RefrigerantHQ's Pressure Charts

One of the very first steps when it comes to diagnosing your home air conditioner, refrigerator, or even your vehicle’s air conditioner is understanding the temperature and the current pressure that your system is operating at. Having these facts along with the saturation point, the subcool, and the superheat  numbers for the refrigerant you are working on are essential when it comes to really understanding what is going wrong with your system.

After a visual inspection the very next step for the most seasoned technicians is pulling out their gauges and checking the pressure and temperature. It just becomes second nature after enough calls. I have heard stories of rookie techs calling some of the pros on their team for help on a system that they’re stuck on. It doesn’t matter what the situation is. It doesn’t matter if you’re in Miami or in Fargo. It will never fail that one of the first questions the pros ask the rookie is what is your subcool and what is your superheat? Having  and understanding these numbers is key to figuring out what to do next.

But, these numbers won’t do you any good if you don’t know what refrigerant you are dealing with and what the refrigerant’s boiling point is at each pressure level. This article aims at providing you with just that information.

R-448A Solstice N40 Basic Info & PT Chart

It seems that as the years go by we face more and more pressure to begin phasing down HFC refrigerants. As I write this article most HFCs have already been phased down across the European Union and we are not too far behind here in the United States. When a class of refrigerants are phased out there obviously needs to be another to step up and take their place. The debate is still raging on rather that should be natural refrigerants or if we should go with the newer class of refrigerants known as Hydrofluoroolefins (HFOs).

The newer refrigerant R-448A, also known as Solstice N40, is an HFO refrigerant. It was introduced by the Honeywell corporation under their new Solstice brand line. While 448A can technically be classified as an HFO refrigerant it actually has more HFC refrigerants in it. This refrigerant is a zeotropic blend of R-32 (26%), R-125 (26%), R-134a (21%), R-1234ze (7%), and R-1234yf (20%). This N40 refrigerant was designed to replace the ever popular HCFC R-22 and the HFC R-404A.

It can be used for new installations and in retrofits. I won’t get into retrofitting here, but there are many guides from OEMs and Honeywell that take you through step by step. One word of warning though is if you are trying to retrofit an R-22 unit over to this refrigerant you should know that R-448A requires POE oil while R-22 requires mineral oil. They are not interchangeable. R-404A does use POE oil so there won’t be a problem there.

This refrigerant is designed for use in low and medium temperature applications such as supermarket refrigeration, refrigerated cold stores, refrigerated transport vending machines, and industrial refrigeration. This N40 refrigerant from Honeywell has an A1 safety rating from ASHRAE. What that means is that the refrigerant is non-toxic and is not flammable. That is a big deal as so many refrigerants nowadays are rated either flammable or slightly flammable.

As I had mentioned earlier, the main point of switching to these new HFO refrigerants is to protect the climate. In the case of R-448A you will see a sixty-eight percent reduction in Global Warming Potential (GWP). That is a significant reduction. Let’s look at the numbers. R-404A has a total GWP of nearly four-thousand. R-448A has a GWP of fourteen-hundred. Along with the savings of GWP you will also find that this Solstice refrigerant runs between five to ten percent more efficient then R-404A. SO, you’ll get the benefit to the climate in two ways.

There is one big downside here on this refrigerant I want to mention before I get to the PT chart. I had stated that the GWP for this product is fourteen-hundred. While it is lower then R-404A you should be aware that it is still a very high GWP number. Because this number is so high I do not foresee this refrigerant lasting in the long run. Its GWP is just too high. I would fully predict that we would see this refrigerant being phased out in just about five years time. It will be replaced by something else down the road. This refrigerant is just a stop gap until we find something better.

Alright folks, I’ve talked enough. Let’s get to the pressure temperature chart. As you are looking over this data please reach out to me if you find something that is not correct. I strive to make these tables accurate and will get any errors corrected as soon as I can.

R-450A Solstice N13 Basic Info & PT Chart

The refrigerant known as R-450A is brought to you by the Honeywell corporation. This refrigerant falls under their new Hydrofluoroolefins (HFO) Solstice line of refrigerants. You may see R-450A referred to as N13 which is the official Honeywell brand name. As most of you know there has been a push to phase out HFC refrigerants such as R-134a, R-404A, R-410A across the United States. This push is due to the very high Global Warming Potential these refrigerants have.

R-450A was introduced as an alternative to the commonly used HFC R-134a. 134a has a GWP of over fourteen-hundred whereas the new 450A has a GWP of only six-hundred. That is a nearly sixty percent decrease in GWP saved by switching over to this new HFO refrigerant. It is also slightly more efficient then R-134a so users will end up seeing a savings on their energy bills as well. 450A is a Azerotropic blend of forty-two percent R-134a and fifty-eight percent of R-1234ze that uses POE oil for lubrication. While it is a mixture of HFCs and HFOs refrigerant it technically falls under the HFO classification. The good news here is that HFO refrigerants are classified as flammable or slightly flammable… but not the Solstice N13. It has an A1 safety rating from ASHRAE. That is the same safety rating that R-134a and all of the other common HFC refrigerants has. To me, that is a big selling point. There is no risk here unlike the risk you could find of when dealing with hydrocarbon or natural refrigerants. The only real thing to be concerned about here is that it still has a somewhat high GWP number… so it may be phased out in five or ten years.

This HFO refrigerant was designed to be used in a variety of medium temperature applications such as refrigerated transport, heat pumps, chillers, vending machines, super market cascade systems, and commercial/industrial refrigeration. It has been approved for use in many of these applications by the Environmental Protection Agency’s SNAP program as well. In fact, it was approved a few years ago now so you may have already run across it before. In most cases you’ll find it in only newer applications, but there is the possibility of a retrofit when it comes to vending machines.

Lastly, before I get to the PT chart I wanted to inform you that this refrigerant can actually be charged from either the liquid or the vapor phase. It is your choice. That is why in the table below I included PSIG for both liquid and vapor. If you have any questions on the table or if something appears to be incorrect PLEASE reach out to me and I will get the information updated just as soon as I can.

Last week I saw a few headlines surface about R-1234yf that caught my attention. The premise of these articles was that the very popular HFO R-1234yf was toxic. Now, if true, this is a huge deal. There was already a significant battle in the European Union when R-1234yf was first being rolled out about the flammability risk and now… we may have a potential toxicity risk as well?

Let me back up for a moment here folks. First a brief history lesson, as many of you know the HFO R-1234yf was brought into the market as a replacement for the HFC R-134a. This was done due to R-134a very high Global Warming Potential number of one-thousand four-hundred and thirty. Every time R-134a was released into the atmosphere either by leak, accident, or on purpose it actively impacted Global Warming and Climate Change.

To prevent further damage to the climate automotive manufacturers begin transitioning away from 134a over to this new HFO. 1234yf only had a GWP of four. A remarkable difference when compared to 134a. The problem with 1234yf is that it is flammable. This flammability rating caused a lot of hesitation from automotive manufacturers. In fact one of them, Daimler, fought the change tooth and nail. Eventually, they came up with their own automotive air conditioning system using R-744 Carbon Dioxide.

Eventually the fight on the flammability risk was nullified and we began to see more and more vehicles switch over to R-1234yf. As I write this article today ninety percent of new vehicles are using this HFO refrigerant. Each year that passes we are seeing more and more manufacturers switch over. The flammable risk was accepted as a necessary risk for helping the environment.

The Study

Last week there was a study done by the Advancing Earth and Space Science association (AGU). AGU is a scientific research firm that works in growing the exchange of scientific knowledge through publishing studies and holding meetings. They are based out of Washington District of Columbia. One of their most recent studies found that R-1234yf is toxic. Now when I use the word toxic it is not like how other refrigerants are toxic. For example, if there is an ammonia leak then it can be extremely deadly. That is why that refrigerant is rated as a B2L from ASHRAE.

R-1234yf is still rated as an A2L refrigerant from ASHRAE. Class A rating on toxicity signifies refrigerants for which toxicity has not been identified at concentrations of less than or equal to four-hundred parts per million. The difference here is that this study focused instead on what the refrigerant does when released into the atmosphere, specifically on Trifluoroacetic acid. I wasn’t familiar with this type of acid so I had to do a bit of research.

“Trifluoroacetic acid (TFA) is a breakdown product of several hydrochlorofluorocarbons (HCFC), regulated under the Montreal Protocol (MP), and hydrofluorocarbons (HFC) used mainly as refrigerants. Trifluoroacetic acid is (1) produced naturally and synthetically, (2) used in the chemical industry, and (3) a potential environmental breakdown product of a large number (>1 million) chemicals, including pharmaceuticals, pesticides, and polymers. The contribution of these chemicals to global amounts of TFA is uncertain, in contrast to that from HCFC and HFC regulated under the MP.” – Source

As you can see from the above quote these Trifluoroacetic acids are found in all of the man made refrigerants such as HCFCs, HFCs, and HFOs. The difference though is the amount that is found in each classification of refrigerant. You see folks, it turns out that HFOs are significantly worse when it comes to TFAs. The below quote is from the study that AGU completed:

“Replacement of HFC‐134a with the short‐lived hydrofluoroolefin (HFO) HFO‐1234yf as the coolant in mobile air conditioners will lead to an increase in TFA deposition. The yield of TFA from HFC‐134a is <0.2, while the yield from HFO‐1234yf is 1. One model estimates replacement of HFC‐134a with HFO‐1234yf will result in annual TFA wet deposition of 160–240 μg m−2 in continental North America (Luecken et al., 2010), which is higher than the cumulative deposition during the last decade of record for each ice core (Devon Ice Cap, 110 μg m−2 (2005–2014); Mt. Oxford icefield, 127 μg m−2 (2007–2016)). Another model predicts annual TFA deposition of 42.3 μg m−2 to the area including the Devon Ice Cap (Wang et al., 2018). This represents an increase compared to our observed annual TFA fluxes from 2001 to 2014, which ranged from 3.9 to 21.5 μg m−2 a−1. Both models suggest a large future increase in TFA deposition in the Arctic compared to our measurements from 1970 to 2015.” – Source

That definitely paints a picture of the difference between HFCs and HFOs. The HFOs contribute five times as much TFA when broken down into the environment. The question now though is what impact will this have on the environment? Does everything need to change? The below quotes I found from National Library of Medicine. They go into the impacts that TFAs have and will have on the environment:

“Total contribution to existing amounts of TFA in the oceans as a result of the continued use of HCFCs, HFCs, and hydrofluoroolefines (HFOs) up to 2050 is estimated to be a small fraction (<7.5%) of the approximately 0.2 μg acid equivalents/L estimated to be present at the start of the millennium” – Source

“As an acid or as a salt TFA is low to moderately toxic to a range of organisms. Based on current projections of future use of HCFCs and HFCs, the amount of TFA formed in the troposphere from substances regulated under the MP is too small to be a risk to the health of humans and environment. However, the formation of TFA derived from degradation of HCFC and HFC warrants continued attention, in part because of a long environmental lifetime and due many other potential but highly uncertain sources.” – Source

Conclusion

So the question now is what will happen next? Will this be enough to warrant another phase down in the next five, ten, or twenty years? If so, then what will be the next logical step for automotive applications? Also, it is not just automotive applications. Could this TFA problem found in 1234yf carry over to other up and coming HFO refrigerants?

Should we continue to pursue the HFO route, or should we begin looking at natural refrigerants such as CO2, Ammonia, and Hydrocarbons more seriously? Time will tell I guess…

I was thinking about this very topic earlier today. As we all know HFC refrigerants are being phased down across the world. While we are still lagging behind within the United States we can be assured that HFC’s do not have much of a future. There are many states pushing their own individual legislation on HFCs as well as bills in the Senate and the House. We have seen it all before with CFCs and most recently HCFCs with the phase out of R-22 finalizing at the beginning of this year. It is something we have grown accustom too and something that many business owners have to adapt to.

There have been a few proposed solutions to replace popular HFC refrigerants such as R-404A, R-134a, R-410A, and R-507. The first is getting back to our roots and using classic refrigerants such as hydrocarbons, ammonia, or carbon dioxide. These refrigerants have all been tried and true and while they each have their own specific downsides it may be time to look at them again. Over the decades technology has improved these natural refrigerant systems. There aren’t as many failures in the high pressure carbon dioxide systems. There are more specific safety precautions and charge limits built into hydrocarbon systems. Best of all, these natural refrigerants are all nearly climate neutral. They have no Ozone Depletion Potential and very low Global Warming Potential. The obvious downsides is that they can be expensive when compared to artificial refrigerant systems and there is also the flammability, toxicity, and high pressure risks.

The other proposed solution and one which is taking on steam right now are the new classification of refrigerants known as Hydrofluoroolefins, or HFOs. These HFO refrigerants are synthetic refrigerants just like their HFC predecessors. The difference is that the HFO refrigerants are more environmentally friendly then the very high Global Warming Potential HFC refrigerants. One of the most successful HFC to HFO switchovers can be found in the automotive market. Rewind about six or seven years and every vehicle was using the HFC R-134a. 134a has a GWP of one-thousand four-hundred and thirty. Around 2014/2015 vehicle manufacturers begin switching their new models away from HFC 134a and over to the newer HFO known as 1234yf. This yf refrigerant has a GWP number of only four. That is a huge difference between the two refrigerants.

The Global Warming Potential scale is a measurement of how much impact a specific gas has on the environment, or more specifically on global warming. The common HFC refrigerants we use today are known as ‘Greenhouse Gases,’ or ‘Super Polluters.’ These gases contribute a significant amount to the warming of the planet, more so then standard carbon dioxide. In fact the GWP scale is based off of carbon dioxide, or R-744. R-744’s GWP is one. So, any gas that has a GWP number greater then one can be seen as harmful to the environment. This is precisely why we are seeing the phase down of HFC refrigerants across the globe.

Now we know that there are no perfect refrigerants and alternatives to HFCs are still going to measure on the GWP scale. It is now just a question of how much? In the example we gave above on automotive applications we saw that switching from R-134a over to R-1234yf we were able to shrink the GWP number by over one-thousand fourteen-hundred. That is a significant amount and I can see the HFO R-1234yf being used in cars in the distant future. This is what we want to see when moving applications away from HFCs and over to HFOs.

The question now though, and the reason I am writing this article, is what to do when a new alternative HFO refrigerant is suggested or used even though that new refrigerant still have a high GWP? Earlier today I was reading an article on how the National Hockey League has been transitioning their ice rinks away from their older R-22 or R-507 systems and over to a newer HFO refrigerant known as R-449A (Under the brand name of Opteon XP40).

This is all well and good but when I looked at the GWP of R-449A I was quite surprised. This HFO refrigerant has a GWP measurement of one-thousand four-hundred and forty-nine. That is NOT a low number. While, yes, it is significantly lower then R-404A and R-507 it is still high. Let us look at a few numbers here. R-404A and R-507 has a GWP of nearly four-thousand. By switching away from these HFC refrigerants and over to R-449A there has been significant impact on the environment. However, if we look at switching from an old R-22 system over to R-449A there is much less of a savings. R-22 has a GWP of around eighteen-hundred. The difference here is that when switching over to R-449A you are removing the Ozone Depletion Potential risk that you have with R-22.

My concern is for the businesses that are investing in these all new machines with HFO refrigerants. In the example of the article I mentioned above, lets say that an ice rink retired their old R-22 system and installed a new HFO R-449A system. While they are reducing their environmental footprint at the time what happens in the future when it is decided that refrigerants with a GWP of over one-thousand are no longer suitable? Or, let us go even stricter and say that refrigerants with GWP of no higher then five-hundred? Stricter regulations and laws are always being introduced on refrigerants and I just do not see it making sense to investing in a whole new system only to have it deemed as environmentally harmful in five, ten, or fifteen years later.

Now, I am not saying all HFO refrigerants are like this. There are many that have very low GWP just like the 1234yf that we had mentioned earlier. The question on my mind though is should businesses really be looking at these HFO refrigerants that come with a high GWP? If it was me then I would only look at the HFOs with a high GWP if I am aiming to retrofit my existing system away from an even higher GWP refrigerant. If instead I am looking to purchase a whole new system then I would either go with a natural refrigerant or with an HFO refrigerant that has a very low GWP number. This would significantly reduce risk of another phase out on the refrigerant you selected.

The table above shows the various HFO refrigerants out there and their related Global Warming Potential number. You’ll notice that more then half of them have a GWP of over five-hundred. How long will these refrigerants be around? Will they be sustainable in the future? Or, will they end up biting the dust just like CFCs, HCFCs, and now HFCs?

How Much Does It Cost?

Well folks it is that time of year again already. Thanksgiving is just a few days away and the temperatures outside are thirty degrees or even colder here in Kansas City. Most people are focusing on the upcoming feast on Thursday or Black Friday that comes immediately after. I on the other hand am focusing on one thing this week and that is refrigerant. Yes, during this holiday refrigerant is on my mind… as it always is. You see during these colder months I find that things begin to slow down. The season is over and everyone has time to catch their breath. I have sometime to relax, think, and time to write articles.

Over the past five years or so I have taken the time to write a series of articles known as my ‘refrigerant price per pound’ posts. These articles aim at providing the end-user with the knowledge on exactly how much a refrigerant costs. These posts have quickly become some of my successful as this information just isn’t out there. If you search for refrigerant pricing you either can’t find much of anything and the stuff that you do find is at very highly inflated prices. Our goal here is to find the most up-to-date and realistic prices on refrigerants.

In this article we’re going to give you an accurate price per pound on R-1234yf. But, before we get into that I first want to take some time and go over some air conditioning basics for your vehicle. If you’re not interested in this and you are just looking for the price then please scroll towards the bottom of the article and look for a section titled, ‘Price Per Pound.’ Otherwise, if you are interested then please read on.

Know This Before Purchasing

Let’s say your vehicle’s air conditioner is no longer working. You’ve tried everything you can think of. You even tried a few AC recharge kits and the air only stayed cool for a few days. It is clear that you need a repair… but what should you expect with this repair? Obviously, every dealer or repair shop is going to charge differently for their parts and labor but the below section will at least give you some basic knowledge on what to expect as you take your car into the shop.

R-1234yf VS R-134a

Something that a lot of folks may not have realized is that in recent years the refrigerant that automobiles are using has switched. Yes, that’s right. A lot of newer vehicles are no longer using R-134a. Instead they have switched over to a newer HFO refrigerant known as R-1234yf. In the United States this switch started to occur in 2015 and with each passing year the number of cars that are using 1234yf has increased. In the next few years it is predicted that nearly ninety percent of the market will be using 1234.

Earlier this year I did an article where I put together a list of all cars and what refrigerant they were using for their 2019/2020 model years. This list took quite a bit of time as I had to dig through instruction manuals for all of these different vehicles. I didn’t find every single car but I found the majority. At the end of the exercise I had found that nearly seventy percent of cars produced in 2019 within the United States are using r-1234yf. That is a huge number folks. This article can be found by clicking here.

There is a really big downside when it comes to r-1234yf. That is the price. In most cases r-1234yf is ten times more expensive then r-134a. So, your thirty dollar recharge on r-134a may end up being close to three-hundred dollars on 1234yf. That is quite the difference and can result in a lot of angry consumers when they get their repair bill. The bad news here is that I have seen no sign of the 1234yf pricing dropping anytime soon either.

You Are Paying For Expertise

Ok folks, so the information that I am going to give you in our ‘Price Per Pound’ section is very nearly, if not exactly, the cost that your technician is paying for their R-1234yf refrigerant. What that means is that you can expect a markup. After all, the technician and the dealership need to make money as well. This is a specialized trade and requires trained expertise in order to succeed in. Thinking that you can do this yourself is never a good idea as there are a lot of intricacies that need to be accounted for. As an example, let’s go through and ask a few simple questions that a technician would either have to do or consider:

  • Do you know how to flush your system?
  • Do you know what refrigerants can be vented?
  • Are you 609 certified with the EPA to handle HFC refrigerants?
  • Do you know how to find, let alone fix, a refrigerant leak?

All of these questions and more are what you are paying your technician for. Remember that they need to make money too, but there is also a fine line between having profit and gouging. Reading this article, and reviewing the price per pound, will allow you to be educated and give you the power to negotiate the price of refrigerant.

Your AC Unit is a Closed System

Refrigerant Cycle in a Closed System
Refrigerant Cycle in a Closed System

Even before you bring your car into the dealership to look at the air conditioner you should be aware that air conditioners are what’s known as closed systems. What that means is that the refrigerant in your air conditioner moves back and forth between different cycles and it, in theory, never runs out or needs refrigerant refilled.

If you find that your unit is low on refrigerant or is completely out do NOT just refill your machine with a new refrigerant. I repeat do NOT do this. Your system does not need a top off. It does not need just a little bit more refrigerant to get by. No. If you are running out of refrigerant that means that somewhere in the refrigerant cycle there is a leak. Your unit is leaking refrigerant and will continue to leak refrigerant until a repair is made. If you dump more refrigerant into it without fixing the leak you are literally throwing money down the drain.

I like to think of it as a above ground pool. If you get a puncture in the pool lining water will leak out. Sure you can always add more water but it’s not fixing the problem. Adding more refrigerant doesn’t fix the problem either. It’s just prolong the inevitable and wasting money.

Purchase Restrictions

This isn’t as big of a problem when it comes to automotive application but it is still worth mentioning. You see back in January 1st of 2018 a new regulation was implemented by the Environmental Protection Agency. This regulation known as the, ‘Refrigerant Sales Restriction,’ aimed at preventing novices from purchasing HFC refrigerants such as R-410A, R-404A, R-134a and yes… R-1234yf.  These restrictions already existed on HCFC and CFC refrigerants but they were now moved over to HFC and HFO refrigerants as well. What this means is that you are no longer legally able to purchase R-1234yf unless you are 609 certified with the EPA. Now, there are a few slight exceptions to this such as:

  1. The first exception is that if you purchase small cans of refrigerant that are under two pounds of refrigerant or less. This works great for automotive applications as they only need a few pounds to recharge an entire system. But, this can be difficult when trying to recharge a larger system with only a pound of refrigerant at a time. A typical split-system air conditioner may take up to twelve pounds of refrigerant. So, you could technically do this yourself but you would have to find a source for the cans and it still not legal to tamper or tinker on an air conditioning unit if you are certified with the EPA.
  2. The other exception is providing the vendor you are buying from with an intent to resale form. What this means is that you state that you will NOT be using this refrigerant yourself but that you intend to resell it to another party. In this case the legal record keeping requirements would be passed onto you. So, if the supplier you bought from gets audited by the EPA their records will then point to you. The EPA will reach out to you and you better hope you either sold the product or are 609 certified!

If you do not meet the above exceptions and you try to purchase R-1234yf you will be asked for your 609 license number. If you cannot provide one then you will not be allowed to purchase. This was done to protect the environment. If R-1234yf is vented or leaked into the atmosphere it contributes to Global Warming. The restriction was put into place to prevent novices from playing around with the refrigerant and accidentally releasing it into the atmosphere.  There was talk at the beginning of 2019 that the Trump Administration would rescind these restrictions but so far there has been no follow-through on this matter. As the law is today you are not able to purchase this refrigerant.

The good news here is that this doesn’t affect the automotive market too much. Yes, there are larger cylinders of 1234yf available but there are also cans available. These cans can be purchased either online through websites like Amazon.com or at your local automotive parts retailer.

R-1234yf Price Per Pound

Alright folks so we’ve gotten past the need-to-know section and now we can begin to dive into to see the exact cost per pound. Let me paint a picture for you now. Let’s imagine it is the middle of summer and your car’s air conditioner has gone out. No cold-air is blowing through and you’re stumped. You drive the car into the dealership for a repair, but what can you expect? The first thing is that you will need to pay for a repair to fix whatever caused the malfunction. This could be a faulty hose, a bad compressor, a bad evaporator, and so on and so on. On top of this you will also have to pay for a full refrigerant recharge. But, what price is fair here?

Before I give you the price on R-1234yf I first want to give you a few tools that will allow you to determine the true cost of R-1234yf at any given time. You see, I am writing this article in November of 2019 and I can bet that by the time summer rolls around and you’re reading this article that the prices have changed. Refrigerant pricing is ever changing and you never truly know where it will be at. The good news is that if you check Ebay.com and Amazon.com you can begin to see where the market is at any given time. Yes, it’s really that simple folks.

When looking at these prices on Ebay and Amazon be sure to look at the ten pound cylinder pricing. That is going to be quite a bit cheaper then the cans and that is most likely what the dealer or repair shop you are at are buying. From my experience these dealerships will buy a pallet full of cylinders and use them throughout the season. This gives them a very aggressive cost within the market. Some smaller shops may only buy five or ten of these cylinders at a time, but they still get a rather aggressive cost.

Today, if we look at Ebay we can see that ten  pound cylinders are ranging from six-hundred and seven-hundred dollars per ten pound cylinder. For argument’s sake let’s take the highest dollar one at seven-hundred dollars. In order to get the price per pound let’s do some simple math:

$700/ 10 lb cylinder = $70.00 per pound.

There you have it folks, $70.00 for one pound of R-1234yf refrigerant. Now, please keep in mind that these prices CAN change. To give you a bit more help I have also included a feed from our Ebay partner below that shows you the current market price of R-1234yf:

Now each car is different and the amount of refrigerant that they need can be different as well. Some only require one pound and others upwards of eight to nine pounds. It is always best to check your owner’s manual or your dealership to see how much you need. In our example we’re going to call it three pounds of refrigerant to get a complete fill up of your vehicle.

3 pounds of refrigerant * $70.00 per pound = $210.00 for a complete fill up.

Conclusion

Alright folks, that should about cover it. I’ve gone through everything you should know when refilling your air conditioner as well at what price point to expect. One last thing I wanted to mention before closing this article is that you have to remember that there will be mark-up involved from your technician or HVAC company. The price that I gave you is going to be very close to their cost. So, while you may not get that $70.00 price per pound article it does give you a starting point for negotiations. Remember, that everything in this world is negotiable and if they quote you one-hundred and twenty-five dollars a pound then you do your best to get them down to ninety dollars a pound using this article as a point of reference.

Thanks for reading and I hope this article was helpful,

Over the past few years the biggest concern when it came to refrigerants has been their Global Warming Potential. The higher the number the more damage that refrigerant could do to the environment. The Ozone problem has been fixed, more or less, due to the Montreal Protocol. In fact, just this month scientists announced that the Ozone hole is at the smallest it has ever been recorded. The problem today though is Global Warming or Climate Change. It seems that ALL of the popular HFC refrigerants used today have a GWP problem. Alternatives needed to be developed.

As we all know, there is no perfect refrigerant. There are always sacrifices that have to be made when selecting a refrigerant rather this be safety, environment, performance, or cost. Because of all of the press and news coverage that Climate Change has been receiving the world has been focused on reducing all of these refrigerants’ environmental impact. The smaller the GWP number the more friendly the refrigerant is to the environment.

The problem here is that the alternatives on the marketplace today that have a lower GWP number also come with a higher flammability rating. The HFCs that we all know and love today are mostly all rated as a ‘1’ on ASHRAE’s flammability scale. These refrigerants show no sign of flame propagation when tested in air at 21° Celsius (69.8° Fahrenheit) and 101 KPA. (14.6488 pounds of force per square inch.) These refrigerants are also non-toxic and are rated as an A1 on ASHRAE’s scale. They are very safe to technicians and to end-users.

The alternative refrigerants that are now being used in place of R-410A, R-404A, R-134a, and other HFCs are NOT rated as a ‘Class 1’ on the flammability scale. Depending on the refrigerant you will most likely see them rated as a ‘Class 2’ or a ‘Class 2L.’ These refrigerants are slightly flammable, or have a lower flammability rating. In some cases HFC alternatives, like Hydrocarbons, are rated as a ‘Class 3’ on the flammability rating scale. These refrigerants are in the higher flammability risk zone, some examples of them are R-290 Propane and R-600a Isobutane.

While some of these replacement refrigerants have been around for decades, others are being developed in laboratories as we speak. Honeywell and Chemours both have their own newer product lines known as Solstice and Opteon. These lines mainly focus on HFO refrigerants but also have some HFC releases as well. In both instances though these new refrigerants are classified as lower flammability. Some examples of these are the ever-popular automotive application known as R-1234yf and then Honeywell’s R-452B (Solstice L41y.)

In the past the United States has been hesitant to use refrigerants with flammability risk. Safety was the priority for us. If the choice was between environmental harm or worker/end-user safety we seemed to choose safety most of the time. This isn’t as true for the rest of the world. Countries in eastern Asia have been working with hydrocarbons and other flammable refrigerants for decades without any major issues. But, there is a lot more training and precautions that have to be taken in order to work on a propane system correctly.

The question that I have in my head, and what caused me to write this article today, is that is the United States ready to adopt these flammable refrigerants? I’m not just talking about in vending machines or super market coolers folks. No, are we ready to accept flammable refrigerants in a traditional home or office split system? R-32 is looking to do just that. Over in Europe and Asia it has become one of the leading refrigerant for split system applications and is widely seen as the replacement for R-410A. R-32 is rated as 2L, so it is only slightly flammable, but the risk is still there.

Looking at the Environmental Protection Agency’s SNAP approved refrigerants list I do see R-32 on there as an approved refrigerant for home and office air conditioning. The catch is that it has to be “for use in self-contained room air conditioning; see rule for detailed conditions.” (Source). So, the applications are still limited for now, but that may change in the near future. Mini-split R-32s have become quite popular as well. I believe it’s only a matter of time before we start seeing R-32 in split systems.

I am curious, what my readers think of this. Do any of you see problems with flammable refrigerants? What are your thoughts on the refrigerant pendulum swinging away from safety and over to environmental? Will you feel comfortable working on systems with these types of refrigerants? I’m anxious to hear your thoughts on the matter as all I see on the topic are others who have written articles. Please feel free to e-mail me your thoughts!

I read an article earlier this week on counterfeit 1234yf refrigerant being caught at a port in Poland. This refrigerant was no doubt bound for the Western European market. Polish authorities, in co-ordination with Honeywell, seized the counterfeit shipment and had it destroyed at the purchaser’s expense. As most of you know R-134a was phased out entirely in new vehicles within the European Union. While there was not a specific refrigerant chosen as a replacement most of the market moved towards this new HFO known as R-1234yf. It had a low Global Warming Potential, it had no Ozone Depletion Potential, and it was only slightly flammable. It seemed like the perfect solution.

This was great news to the big refrigerant manufacturers Honeywell and Chemours (DuPont). These two companies hold patents on 1234yf. This patent is not expiring anytime soon. In essence, these two companies have a monopoly on the automotive market within the European Union. There is an alternative refrigerant, CO2/R-744, that was developed by the German company Daimler… but it is still in it’s infancy stages and is not widely used in new models yet.


After writing this article I was informed that I was mistaken when it comes to the patents on 1234yf. There are various patents that are held on 1234yf and they fall into two categories. The first is known as the process patent and the other is known as the application patent.

The process patent is a patent on the recipe that is used to create HFO 1234yf. Honeywell holds a patent here, but there are other ways to create 1234yf. So, outside companies can produce 1234yf legally and hopefully come in at a competitive price point.

The application patents are just that. They are patents on the certain applications that 1234yf can be used in. Honeywell for example holds patents using 1234yf in automotive applications. So, while other companies can produce 1234yf we are still at a bottleneck with the application patents. The good news is that these may expire earlier then the 2030 date that I had mentioned earlier.


The price on R-1234yf is a whole other story. Typically, you could get a pound of R-134a for around three-dollars. This is what folks were used to and what they expected to pay if they needed an air conditioning repair. R-1234yf however is in a whole other ballpark. Your typical price per pound on this product could range from fifty to seventy dollars a pound.  That is nearly a two-thousand percent increase in price to businesses and customers.

So, now let’s look at this critically. We have a very high priced product, a product that is produced by a select few companies, and it is a product that EVERY vehicle within the European Union needs. I’m sorry folks, but these three points means that this is a prime candidate for counterfeit or fraudulent product to hit the market. This is just human nature. Yeah, there is a risk if these folks get caught but there is also a huge reward: profit. Think if this counterfeit product hits the market at twenty percent less then the genuine Honeywell/Chemours product. Customer gets a significant savings and the business behind it makes a killing.

In order to stop this fraudulent product Honeywell has been working with various governments within the European Union and even with China. There was a publicized incident last year in the Czech Republic where fraudulent 1234yf was found at a port. The year before Honeywell and the Chinese government prosecuted a person involved in the production and sale of counterfeit 1234yf. This individual received nine months in jail. There was another incident reported by the CoolingPost last month. This time a shipment was seized at a Polish port.

Most of this product either comes in to a Eastern European country’s port or it travels by road from China, into Turkey, into Bulgaria, and then to whatever western country they wish. Just like with previous counterfeit refrigerant, the product is coming from China. These are most likely the same guys who were producing counterfeit R-22 a few years back when R-22’s price had hit record highs. It was also the Chinese that was found to be violating the Montreal Protocol by still widely producing and using R-11. It is not a surprise that they are diving into the fraudulent HFO market.

Honeywell states that they are going after these fraudulent 1234yf products to protect consumers and to protect their equipment.  They may very well have the interests of protecting consumers but, in my opinion, all this is is Honeywell protecting their monopoly and aggressively going after anyone tries to infringe on their market. Whatever their motivations are they are going to have one hell of a game of whack-a-mole on their hands. The Chinese have been very lackadaisical when it comes to enforcing regulations and preventing illegal products from being manufactured and sold. For every company that Honeywell goes after another one will pop right back up.

Who knows folks, maybe this product is one-hundred percent clean and is made to the same specifications that Honeywell/Chemours have set forward. Even if it was though it would still be targeted and destroyed for patent infringement.  I won’t make a lot of friends by saying this, but I am not a fan of this monopoly. No two companies should control the entire automotive refrigerant market.

Conclusion

While we haven’t felt the pressure of this high priced HFO product here in the United States I can assure you folks that it is coming and it is coming sooner then you think. Earlier this year I did an article on the number of cars using 1234yf. The numbers were staggering. In 2019 nearly sixty percent of new vehicles use R-1234yf. In just a few years that number is expected to climb to ninety percent. R-134a is being phased out here in the United States as well and the only real alternative at this time is 1234yf.

This trend only really started to hit US automotive manufacturers back in 2015. Most automotive companies state that it takes an average of five to six years for a vehicle to need an HVAC repair. Next year is when we may really start to see that sticker shock when folks begin bringing in their vehicles for an air conditioning repair. We could have a simple compressor replacement and recharge price increase by hundreds of dollars.

Don’t get me wrong folks, I am not advocating for any illegal product. Frankly, it is not safe and you never truly know what you are getting. That being said, there definitely needs to be more competition introduced into the 1234yf marketplace.

Thanks for reading,

The other day I was trying to find a comprehensive listing of which cars were using the newer R-1234yf HFO refrigerant. Over in Europe YF refrigerant is now the standard for all new vehicles. (In some cases R-744 is used as well.) R-134a is no longer used due to its high Global Warming Potential.

A few years back the Environmental Protection Agency issued a new SNAP Rule known as ‘Rule 20.’ This new rule stated that a lot of the most popular HFC refrigerants would no longer be acceptable in new applications. One of the refrigerants and applications listed was R-134a for all 2021 vehicle model years.  This all but dictated that automakers would have to use 1234yf in all of their new vehicles.

Well, as you all know, Rule 20 by the EPA was overturned by Federal Courts. The EPA had overreached their authority and had their proposed rules thrown back in their face. Having this rule thrown out left the future of R-134a uncertain. We all knew that 134a wasn’t going to be around forever. It did have a high GWP and it did need to go… but now there was no government mandate to do so.

Most everyone thought as the years passed by auto manufacturers would begin to switch to 1234yf without a government mandate. After all, it was the cleaner option and other states such as California and New York have begun to phase down HFC refrigerants.  It only made sense to protect yourself and make the switch over now.

Top Selling Cars in 2019

All that being said I was curious exactly what automakers and models of cars are now taking the HFO 1234yf refrigerant. How many of them are still holding onto the past? Since I couldn’t find an exact list I took a different approach.

I googled for a listing of the top selling cars of 2019. What I found was a listing of two-hundred cars from a website called ‘goodcarbadcar.net.’ The listing had sales volume, dollars, etc. I was only interested in the ranking though. What was the number one car sold, number two, etc.

Now that I had my listing I cut it down to the top fifty and then begin going to work. My goal here was to find out what refrigerant each of these 2019 model year cars were using.  Some of these were harder to find than others. In most cases I googled the year, make, model, and ‘owner’s manual.’ Usually I could find the manual and then find the refrigerant type in there.

In other cases I found the manual but the manufacturer kept the type of refrigerant a secret. In fact nearly anything to do with the air conditioning system was kept secret. The most I could find was to either ‘Check Under The Hood,’ for the refrigerant type, or to contact your dealer for maintenance questions. In these circumstances I Googled around a bit more and did my best to fill in the blanks.

The completed table can be found below. Overall, I couldn’t find the refrigerant type for eight vehicles. (If you know what they are please reach out to me and I will update the table.) But, for the others that I did find it painted a pretty clear picture of the refrigerant market today for new vehicles.

Let’s look at the facts first. For the top fifty selling cars in the United States only fifteen of them are still using R-134a. The other twenty-seven are using R-1234yf. Even if we give the missing ten cars the benefit of the doubt and state that they are all using R-134a we are still looking at over fifty percent market share of R-1234yf within the United States. Some folks will say as high as sixty or even seventy percent market share.

Even if it’s just fifty percent that is still a HUGE number and it is only going to continue to grow. Each year more and more auto manufacturers make the switch to 1234yf. You may have noticed that in the table some Makes have a mixture of R-134a and R-1234yf. This is most likely them testing the waters with YF. They want to see if everything works as it should before they go all in on YF.

Conclusion

This table provides us with concrete evidence that R-1234yf is taking over the automotive market. If you haven’t come across it yet then I can assure that you will soon. From what I have read the average age of a vehicle that needs an air conditioner repair is between five to six years. So, at that fifty percent market share that we have today we could be looking at half of all vehicle AC repairs being done on YF systems by the year 2025.

R-134a is going the way of R-12. In another ten or fifteen years it’s going to be rare to find an 134a vehicle and when your vehicle does take R-134a you may have to pay a pretty penny to get a recharge. (Just look at how expensive R-12 is nowadays.) The only good news here folks is that there isn’t a mandatory phase out of R-134a yet… so the prices will still stay quite low for the foreseeable future.

The big problem that a lot of end users have with 1234yf is not that it’s a new refrigerant. No, the problem is the cost.  The cost of a pound of R-134a can hover between two to four dollars per pound. The cost of R-1234yf can hover between sixty to seventy dollars per pound. That’s nearly fifteen times more than the cost of R-134a. You can see an example of this cost from our Ebay partner by clicking here.

Because of this huge cost increase there has been a rash of end users manually converting their YF systems back over to R-134a. Hell, there is even an adapter out there for it… Rather these folks like it or not R-1234yf is here to stay and with each passing year the amount of vehicles using it is growing.

RefrigerantHQ's Pressure Charts

The HFO R-1234yf is the refrigerant of the future. Or, at least, that is how it has been marketed. Yf was the first HFO refrigerant to see mainstream attention. A few years back there was immense pressure in the European Union to stop using the HFC R-134a for automotive air conditioning. The pressure was there due to the extremely high Global Warming Potential (GWP) that R-134a has. R-134a has a GWP of one-thousand four-hundred and thirty. It is classified as a super pollutant.

The answer to the world’s problems came with the announcement of the new HFO refrigerant known as R-1234yf. Yf refrigerant has a Global Warming Potential of only four. That is a huge difference when comparing it to other refrigerants on the market today. The only downside for yf is that it is rated as slightly flammable or 2L from ASHRAE and other air conditioning organizations.

The European Union quickly phased down and out R-134a and had their new vehicles start taking R-1234yf. While the acceptance of yf is much slower here in the United States there are numerous vehicle manufacturers who have begun using this refrigerant in their newer model vehicles. With each year that passes more and more vehicles begin taking yf.

1234yf Pressure Chart

One of the very first steps when it comes to diagnosing a vehicle’s air conditioner is understanding the temperature and the current pressure that your system is operating at. Having these facts along with the saturation point, the subcool, and the superheat  numbers for the refrigerant you are working on are essential when it comes to really understanding what is going wrong with your system.

Conclusion

There you have it folks. I hope this article was helpful and if you find that something is inaccurate here in my chart please do not hesitate to reach out to me. I have sourced this the best I could but there is always going to be conflicting data.  I’ve seen it multiple times on various refrigerants. I’ll search for a refrigerant’s pressure chart and get various results all showing different pounds per square inch temperatures.

The aim with this article is to give you accurate information so again, if you see anything incorrect please let me know by contacting me here. On top of this post we are also working on a comprehensive refrigerant pressure/temperature listing. The goal is to have every refrigerant out there listed with a pressure/temperature chart that is easily available.

It was announced today via press release from the Chemours company that their new plant located in Ingleside, Texas (Outside of Corpus Christi) is now manufacturing R-1234yf refrigerant. This factory is by far one of the largest and now that it is live the capacity of HFO-1234yf being produced in the world has tripled.

Today the overall demand for 1234yf is still quite low in the United States. In the European Union volume is beginning to pick up due to their mandatory phase out of R-134a. While there are automotive manufacturers here in the US that are switching their vehicles over to yf it is not yet mandatory. Because of this, we are seeing a slow transition cycle.

Along with the slow change over we also have to keep in mind that if a new vehicle with 1234yf rolls off the floor today that same vehicle may not need an air conditioning repair for another four years. The standard amount of time for a new vehicle to need air conditioning repair is between five to six years. So, even though we had a lot of manufacturers and models switch to yf in 2015 we are still a ways out before the demand of yf is heightened due to automotive repairs.

The good news here though is that with this new plant live and producing yf here in the United States we should begin to see the price dip. Yf still continues to be one of the most expensive modern day refrigerants on the market place. Today it ranges between sixty to seventy dollars a pound. (R-134a is about three dollars a pound.) With the increased supply coming into the market we may begin to see this price drop. Well, at least until the demand starts to climb, then we could see prices level back out.

While we mostly know R-1234yf as the new automotive refrigerant it is also important to note that it is used in other various HFO refrigerant blends such as R-455A and R-513A. As more HFOs are developed in the future we may begin to see the versatility of yf expand. If this happens then we could see another effect on the overall demand of the refrigerant. Regardless of the other application market, we can all be certain that the automotive demand is more then enough to satisfy the needs of this production plant.

In my opinion the launching of production of yf at this plant was a bit too early. Now, I didn’t find anything that specifically said that Chemours was going to be producing at maximum capacity or if they were going to slowly start production to meet market needs. I am assuming that they are going to start slow and adjust as the market requires. Either way though, I just don’t see the demand yet. Perhaps Chemours is preparing for the future but if you ask me I would say we are still a few years out before we really see the demand for 1234yf pick up.

Conclusion

In the short term, a savvy investor may have an opportunity if the prices of 1234yf begin to drop due to oversupply. One could wait for the price to bottom out, buy up a few pallets, and then sit on it and wait for the prices to climb. Remember though folks, it’s always a gamble. If the prices do fall whose to say that they’ll go back up? We could be looking at a new normal price point wise on yf with this new plant.

A few days back I was speaking to an acquaintance of mine. It was a relaxed setting with a few beers and good food. Sometime during the conversation the topic of refrigerant came up, mainly 1234yf. You see, he manages a service center at a Ford dealership. He has been doing this job for over a decade and this fall was the first time that he came across a vehicle needing an air conditioning repair that used R-1234yf. They didn’t have any on hand and worse yet, they didn’t have a recovery machine fit for 1234yf either. They ended up having to purchase the refrigerant from a local autoparts store and paid way more then they should have for a recovery unit.

Up until this point everyone at the dealership had been trained and accustomed to using R-134a. After all, pretty much every vehicle on the road within the past twenty to thirty years was using the HFC R-134a. The concept of vehicles using an alternative refrigerant, like R-1234yf, was foreign to a lot of service managers and technicians. Service employees could have twenty years of experience and not know the first thing about this new 1234yf refrigerant.

Over in the European Union it was a different story as R-134a had been completely phased out for years now. While they may have run into the same problems we are having today, the length of these were short lived due to the mandatory switching from 134a over to yf. If EVERY new vehicle on the road was taking 1234yf then you are going to run into it quite often and you will begin to know exactly how to handle it. Things are different here in the United States.

As I write this article today there is no set phase down of R-134a in vehicles in the United States. Originally, the goal was to have R-134a labeled as unacceptable in all new vehicles in 2020. (2021 model year.) This deadline was set by the Environmental Protection Agency back in 2015 through their Significant New Alternatives Policy (SNAP). Years went by as this being the status quo and so vehicle manufacturers here in the US began to slowly switch their vehicles away from R-134a and over to R-1234yf. This trend started in 2015 and with each year that has passed more and more vehicle manufacturers have begun switching more and more models over to yf. Chances are if you check your company’s new vehicles you will see some of them are taking R-1234yf.

There was a wrench thrown into all of this in the summer of 2017. In August of 2017 a federal court ruled that the Environmental Protection Agency’s new SNAP rules had overreached the EPA’s authority. I won’t get into all of the court details here, but basically the EPA used the same set of laws in the Clean Air Act that were intended for Ozone depletion refrigerants and applied them to Global Warming refrigerants. Ozone depletion does not equal Global Warming. They are two different matters and that is how the court saw it as well. The EPA’s proposed 2020 phase down of R-134a was thrown out the window. There were numerous appeals by varying companies and there was even one to the Supreme Court but the court rejected the case and the previous ruling standed. Today we are in limbo between R-134a and R-1234yf.

Preparing for 1234yf

Regardless of what happened in the courts the fact of the matter is that 1234yf is coming. The only thing the court ruling did was muddy the waters and slow down the rate of change. Now instead of having a mandated change and forcing everyone to ‘rip the band aid off’ we now this slow dribble of vehicles coming into shops with 1234yf refrigerant.

What we find is that service managers and technicians are not prepared. When a vehicle does come in needing a repair there is a scramble to first find a source for the needed yf refrigerant and then to find an adequate recovery and identifier machine compatible with yf. The good news here is that 1234yf and 134a aren’t that different mechanically speaking. A few of the major differences that you will see when dealing with 1234yf are listed below:

  • At the very minimum you will need to purchase a new refrigerant recovery machine if you plan to be working on 1234yf units in the future. The machine will have to meet SAE spec J2843. We recommend purchasing Robinair AC1234-6 recovery machine.
  • There are slight design differences in the design specs of certain components like TXVs, ports, evaporators, and condensers.
  • Service ports are different then 134a. This is done to alert the technician that this is a 1234yf unit and also prevents the technician from accidentally connecting the wrong hose and mixing refrigerants. So even if you aren’t paying attention and try to hook up your 134a hose you’ll quickly realize you’re working on a YF unit. This is very similar to what was done with diesels back in 2007 during the Diesel Exhaust Fluid change. (DEF)
  • With 1234yf systems they have added a Suction Line Heat Exchanger, also known as an internal heat exchanger. This is an additional component located before the expansion valve. It is a state change helper that is used to improve overall efficiency of the unit.
  • The operating pressures and temperatures of 1234yf are VERY similar to that of 134a. This was done intentionally to make for an easy transition.
  • 1234yf uses PAG oil just like R-134a but please note that it does use a different type of PAG oil. It is always safest to read the sticker labels under your hood or to consult the instruction manual before adding in any oil.
  • Evaporator designs must meet JAE standard J2842. Yf is tougher on evaporators then 134a and this new standard is to prevent wear and tear and premature failure.
  • 1234yf is classified by the ASHRAE as a 2L flammable gas. That means that 1234yf is rated as mildly flammable.

Conclusion

The good news here is that we still have some time to prepare before the onslaught of 1234yf repairs begins to hit your dealership. The average length of time before a significant air conditioning repair is needed is between five to six years. Yf really began to pick up steam amongst vehicle manufacturers in 2015 and has increased each year that goes by. So, what that means is that we have five to six years from 2015 before the real quantity of repairs begin to come in. While it’s already 2019 we still have around another year or two before we start seeing yf every day in the shop. The worst thing you can do though is bury your head in the sand and hope that the problem goes away. The change is coming.

Will your dealership be ready? Have you already purchased your yf recovery machine? Do you have a source for purchasing yf refrigerant? If not, then I highly recommend contacting us by filling out the form below to receive a quote. We will get back to you with an aggressive price point. Also, please note that in order to purchase yf you or your technicians will need to be 609 certified with the Environmental Protection Agency.

There is no better indicator or barometer within the industry then the Carrier Corporation. After all, they are one of the biggest and most stable air conditioning manufacturers out there. They are one the ‘trend setters’ within the industry. When a business decision is made everyone watches, observes, and they may even imitate. The same can be said when they choose a new refrigerant.

That is exactly what happened. The Carrier Corporation along with Chemours announced today that Carrier would be transitioning their ducted residential and commercial air conditioning products away from R-410A and over to R-454B. This new refrigerant R-454B, also known as XL41, is an HFO refrigerant from Chemours under their Opteon brand name. The transition for Carrier is scheduled to begin by the year 2023. This is a big deal folks. This could very well be the beginning of the end for R-410A. Especially if other companies began to follow suit.

As most of you know there has been a battle going on for the past few years as to what refrigerant will be the golden choice to replace R-410A. It seems like Puron has only been around for a few years but now there are already companies and countries pushing it out and wanting a better more climate friendly alternative. As I write this article today there is still not one clear and defined winner. None of this isn’t for lack of trying though. There are all sorts of 410A alternatives out there, the problem is none of them were gaining significant traction. This news from the Carrier corporation adds fuel to the fire for R-454B. Along with Carrier some other prominent companies have announced their support for XL41 including Johnson Controls and York. With Carrier coming on board I wouldn’t be surprised if we begin to see more companies announce their support in the not too distant future.

The big distinction here and the reason companies are switching to XL41 is that it has a significantly lessened Global Warming Potential then the other alternatives out there. R-454B has a GWP of only four-hundred and sixty-seven. That is nearly eighty percent less GWP then R-410A and even thirty percent less then the proposed R-32 alternative. This very low GWP gives companies and manufacturers peace of mind knowing that they will meet future climate targets today if they make the switch. I would be apt to purchase one of these machines if I knew it was going to stand the test of time and not have to go through a phase down/phase out period.

The downside though with this newer HFO refrigerant is that ASHRAE has it rated as an A2L. The 2L is what may worry some of you, as that means that the refrigerant has lower flammability rating and a lower burning velocity. While some of you may already have experience working with lower or even mildly flammable refrigerants others may not. In reality though folks, flammable refrigerants are perfectly safe as long as you follow all of the proper precautions and safety procedures.

Conclusion

This sheet attempts to provide any and all information you would ever need on 454B. Rather it’s the GWP, the chemistry, what’s in the blend, the temperature glide, or anything else we aim to have it in our fact sheet. If while reading you find something that isn’t accurate or if you found that we missed something please do not hesitate to reach out to me and let me know. I want RefrigerantHQ to be a great resource for those of us in the industry and I can’t do that if I have mistakes up!

Thoughts on R-454B

R-454B, or XL41, was invented and designed by the Chemours company as an alternative to R-410A applications. These applications include your traditional home air conditioners, your commercial air conditioners, heat pumps, and the occasional chiller. XL41 is a blended HFO refrigerant is comprised of sixty-eight point nine percent R-32 and thirty-one point one percent R-1234yf.

One of the biggest attractions of R-454B is the savings in whats known as Global Warming Potential, or GWP. Every refrigerant out there rather it is a hundred years old or it was just invented yesterday has a GWP rating. GWP is a measurement on how potent a certain chemical is to the environment. The higher the GWP number the worse it is. Like with all scales, there needs to be a zeroing point. In this case the zero scale is Carbon Dioxide, or R-744. CO2 has a GWP number of one. As a comparison the commonly used R-410A refrigerant has a GWP of two-thousand and eighty-eight.

Looking at that number we can begin to see the problem with R-410A. It is directly contributing to Global Warming and Climate Change. The reason R-454B is being selected for newer applications is due to it’s much lower Global Warming Potential. 454B’s GWP is four-hundred and sixty-seven. That is nearly an eighty percent decrease when compared to Puron. This impressive number puts it at the lowest GWP alternative to R-410A. To give you some perspective, the other contender as an R-410A replacement, R-32, has a GWP of six-hundred and seventy-five. R-454B is an additional thirty percent lower. Along with that, 454B has a zero Ozone Depletion Potential rating so there is no risk there either. It is a very healthy refrigerant for the environment.

R-454B, or XL41, is classified as an HydroFluroOlefin refrigerant. These types of refrigerants, known as HFOs, are known for a few things. The first is that they have significantly lower Global Warming Potential then the commonly used HFC refrigerants of today. This fact right here checks a lot of boxes for business owners and manufacturers and may be enough to get them on board. However, like with any refrigerant, there is always a downside. HFO refrigerants are also known for their flammability. It seems we never can truly ‘win’ with refrigerants. There are always Pros and Cons.

In the case of R-454B it is rated by ASHRAE as an A2L. The A rating is great as it indicates that the refrigerant is not toxic. Other refrigerants with this same ratings are R-22, R-134a, and R-410A. The problem though lies in the 2L rating. This indicates a lower flammability rating for R-454B. Most of the common HFC refrigerants that we handle today are rated as a 1 by ASHRAE. A 1 rated refrigerant indicates that there is no risk of flame propagation. A 2 rated refrigerant has a lower flammability rating. Now, a 2L rated refrigerant means that along with the lower flammability we also have a lower burning velocity. This 2L sits R-454B right in the middle of the flammability refrigerant scale. While HFCs are rated as a 1 other very flammable refrigerants like Propane (R-290) are rated at a 3.

While a flammable refrigerant may sound intimidating and dangerous we should mention that they are perfectly safe and are used everyday throughout various Asian countries such as Japan and Korea. They do this daily and prevent accidents due to two major factors. The first is that they take the proper precautions when installing and handling flammable refrigerants. The second is routine maintenance. If you follow your training and ensure that everything is done by the book you’ll be fine.

Regardless though, the thought of working with flammable refrigerant deters a lot of technicians and contractors from using these newer HFO refrigerants. Lastly, since R-454B has an increased flammability rating then R-410A you are NOT able to retrofit existing 410A machines over to take R-454B. This is due to the specialized parts and components that a flammable refrigerant needs for it to work safely. If you wish to go with R-454B refrigerant you will need to purchase a whole new machine.

A few other notes worth sharing on R-454B:

  • XL41/454B is rated as five percent more efficient then R-410A Puron.
  • 454B offers the lowest GWP alternative to R-410A all without compromising on system performance.
  • While retrofitting isn’t possible, R-454B will not require major equipment modifications.

Conclusion

It is far too early to say rather or not R-454B will be the fabled R-410A killer or not. There are numerous alternatives out there that are all gaining traction. The question now though is will one of these began to gain speed over the others? Will companies around the globe began to pick one over the other? It may already be happening with R-454B. There are numerous articles and stories out there about companies moving away from R-410A and over to R-454B. Just a few of these companies are Carrier, York, and Johnson Controls. These are all huge names in the industry and may indicate a turning point.

But, as I said before folks, at this point it is still a guessing game. The true alternative for R-410A may have not even made it’s debut yet. Time will only tell.

How Much Does It Cost?

The term Freon is used all over the country to describe the refrigerant that is used in their home, commercial, or vehicle air conditioner. Even though it is used by man the term Freon is actually antiquated and is very rarely used within the HVAC industry. Chances are your air conditioner that you are using right now doesn’t contain Freon.

In fact, the word Freon is actually a brand name from the DuPont, now Chemours, refrigerant company. Yes, that’s right. Freon is just like Coca-Cola or Pepsi. Freon is a brand of refrigerant. There are many brands of refrigerant out there today but the reason we associate Freon with everyone is that Freon was the first mainstream refrigerant that can be traced all the way back to the 1930’s. At that time DuPont and General Motors teamed up together to form R-12 and R-22 refrigerants. These new refrigerants were the first mass produced and widely used refrigerant and air conditioning technologies in the world. DuPont branded these new refrigerants under their trademarked brand name, ‘Freon.’ The Freon refrigerants exploded in popularity and just a few decades later they could be found in nearly every home and office across the country.

All of this changed in the late 1970’s and early 1980’s when a team of scientists discovered that these Freon refrigerants contained Chlorine and Chlorine was leaking into the atmosphere and damaging the Ozone layer. Realizing this, hundreds of countries signed what’s known as the Montreal Protocol. This protocol phased out CFC and HCFC refrigerants across the globe. Included in these phased out refrigerants were DuPont’s ever popular ‘Freon’ brand name.

So, What Kind of Refrigerant Do I Need?

Ok, so the old Freon refrigerants are nearly gone nowadays. Yes, there are still some R-22 units out there and some people still need them but R-22 machines were phased out in 2010 so that means at their youngest an R-22 unit is already nine years old. They are quickly approaching the end of their life. The term Freon will be going away with it. So, now the question is what kind of refrigerant do you need? Let’s take a look:

Automotive Application – Nowadays nearly every vehicle is using R-134a refrigerant for their vehicles. In recent years a new refrigerant known as HFO-1234yf is being used on newer models. If you car is a few years old you will need to check if it takes 1234yf or not. Otherwise you are fairly safe to assume that your car is taking R-134a.

Home or Commercial Air Conditioner – These ones can be a little tricky. Depending on when you got your unit you most likely either have an R-22 unit or a R-410A unit. As I said before R-22 was phased out in 2010 for new units. R-410A has been around since 2010 but it’s popularity didn’t really take off until the 2010 deadline hit for R-22.

Refrigerators and Freezers (Home and Commercial) – The go to refrigerant for these applications has been R-404A. There are some other alternatives out there such as CO2 (R-744), R-502, and some other new HFO refrigerants coming out soon.

Conclusion

I hope that this article was able to answer your questions on refrigerant pricing and to also open your eyes on the wide variety there is within the refrigerant industry. There are two things that I want you take from this post. The first is the relative price per pound of the refrigerant you need and the second is the understanding that your contractor needs to make money too. Sure, you might know his price but you should not haggle down to zero. You should negotiate to a fair price that allows profit but also prevents gouging.

Lastly, if you are unsure what type of refrigerant your system needs please check the label/sticker on the machine. Normally it will state the refrigerant that it takes. However, if you still can’t find it then you can either contact the manufacturer or you can call a HVAC professional out to take a look. This is never something that you want to guess at.

How Much Does It Cost?

Most people couldn’t care less about the pricing of refrigerant. I’m sure you didn’t care at all until your air conditioner broke down. Now you have a contractor at your home or office looking over the damage, or perhaps you have already received a quote from them and you are a little surprised by how much they are charging for refrigerant. Whatever your reason is for reading this article we are going to do our best to answer your question and to give you a fair estimate on what the going price per pound on some of the most common refrigerants on the market place today.

First and foremost, let me first explain that there are hundreds of different types of refrigerants out there. No two refrigerants are the same or work the same either. The air conditioner that you are using is designed specifically for a certain refrigerant and no others. The science of refrigeration and air conditioning all boils down to basic chemistry and understanding when a refrigerant changes states either from gas to liquid or liquid to gas. Each machine is designed to accomdate that refrigernat’s specific saturation point. If you were to add the wrong refrigerant to your air conditioner you could damage or even destroy the system. You wouldn’t put diesel into a gasoline sedan would you? The same principle applies.

In this article we are going to go over some of the most popular refrigerants out there today, their applications, and where they can be found. It will be up to you to determine exactly what refrigerant you need for your repairs.

So, What Kind of Refrigerant Do I Need?

As we mentioned above, there are hundreds of varying kinds of refrigerants out there. A lot of times this can be overwhelming and confusing to a laymen as to what kind of refrigerant they need. The good news here is that for most applications there are only a select few refrigerants that are used here in the United States. In this section below we are going to highlight the most commonly used refrigerants, what their applications are, and what their price per pound is. The price per pound section will have a link to the exact price per pound on that refrigerant.

Let’s dive in and take a look:

  • Automotive Application – Nowadays nearly every vehicle is using R-134a refrigerant for their vehicles. In recent years a new refrigerant known as HFO-1234yf is being used on newer models. If you car is a few years old or brand new then you will need to check if it takes 1234yf or not. Otherwise you are fairly safe to assume that your car is taking R-134a. For those of you who are into restoring classic cars you’ll find that you may end up needing R-12 Freon.
  • Home or Commercial Air Conditioner – These ones can be a little tricky. Depending on when you got your unit you most likely either have an R-22 unit or a R-410A unit. As I said in previous articles, R-22 was phased out in 2010 for new air conditioners. R-410A has been around since 2000, but it’s popularity didn’t really take off until the 2010 deadline hit for R-22. When it comes to cost though you better hope you have a R-410A unit rather than R-22. The difference in price between the two refrigerants is astonishing.
  • Refrigerators and Freezers (Home and Commercial) – The go to refrigerant for these applications has been R-404A. There are some other alternatives out there such as CO2 (R-744), R-502, and some other new HFO refrigerants coming out soon but today if you were having to recharge one of these you are most likely going to run into 404A.

Conclusion

I hope that this article was able to answer your questions on refrigerant pricing and to also open your eyes on the wide variety there is within the refrigerant industry. There are two things that I want you take from this post. The first is the relative price per pound of the refrigerant you need and the second is the understanding that your contractor needs to make money too. Sure, you might know his price but you should not haggle down to zero. You should negotiate to a fair price that allows profit but also prevents gouging.

Lastly, if you are unsure what type of refrigerant your system needs please check the label/sticker on the machine. Normally it will state the refrigerant that it takes. However, if you still can’t find it then you can either contact the manufacturer or you can call a HVAC professional out to take a look. This is never something that you want to guess at.

How Much Does It Cost?

Hello folks and welcome to RefrigerantHQ. As I write this article today Halloween has just passed and the weather has already begun to get cold. We’re expecting snow in just a few days here in Kansas City. All of this is happening outside and here I am sitting at my desk, sipping on some hot cocoa, and thinking about refrigerant. Yes, I know that sounds rather odd… but that is what we do here at RefrigerantHQ. Refrigerant all the time. Today I am thinking about R-1234yf. What can we expect from it next year? What will consumers be paying for it?

Over the past few years here at RefrigerantHQ we have taken the time to write what’s known as our ‘Price Per Pound’ articles. These articles break down the cost of refrigerant so any laymen can understand it. It takes away that hidden cost and brings it out into the light. The goal of these articles is to arm the homeowner or business owner with enough knowledge so that when they receive a quote for R-1234yf they know where the price should be. This prevents people from being gouged and overcharged, especially during the dead heat of summer.

Now before we go any further into this post I first want to give you a warning that I can be rather long winded. All of this information is good and relevant to your situation, BUT if you are just looking for a basic price per pound price then I suggest you just scroll on down to our ‘Price Per Pound’ section. However, if you’re looking to learn a bit more about your air conditioner then by all means keep reading.

Know This Before Purchasing

Purchasing refrigerant from your contractor isn’t always black and white. There are different factors that need to be considered before you purchase. In this section we are going to take a look at each of these:

You Are Paying For Expertise

Ok folks, so the information that I am going to give you in our ‘Price Per Pound’ section is very nearly, if not exactly, the cost that your technician is paying for their R-1234yf refrigerant. What that means is that you can expect a markup. After all, the technician and the dealership need to make money as well. This is a specialized trade and requires trained expertise in order to succeed in. Thinking that you can do this yourself is never a good idea as there are a lot of intricacies that need to be accounted for. As an example, let’s go through and ask a few simple questions that a technician would either have to do or consider:

  • Do you know how to flush your system?
  • Do you know what refrigerants can be vented?
  • Are you 609 certified with the EPA to handle HFO refrigerants?
  • Do you know how to find, let alone fix, a refrigerant leak?

All of these questions and more are what you are paying your technician for. Remember that they need to make money too, but there is also a fine line between having profit and gouging. Reading this article, and reviewing the price per pound, will allow you to be educated and give you the power to negotiate the price of refrigerant.

Your AC Unit is a Closed System

Refrigerant Cycle in a Closed System
Refrigerant Cycle in a Closed System

Even before you bring your car into the dealership to look at the air conditioner you should be aware that air conditioners are what’s known as closed systems. What that means is that the refrigerant in your air conditioner moves back and forth between different cycles and it, in theory, never runs out or needs refrigerant refilled.

If you find that your unit is low on refrigerant or is completely out do NOT just refill your machine with a new refrigerant. I repeat do NOT do this. Your system does not need a top off. It does not need just a little bit more refrigerant to get by. No. If you are running out of refrigerant that means that somewhere in the refrigerant cycle there is a leak. Your unit is leaking refrigerant and will continue to leak refrigerant until a repair is made. If you dump more refrigerant into it without fixing the leak you are literally throwing money down the drain.

I like to think of it as a above ground pool. If you get a puncture in the pool lining water will leak out. Sure you can always add more water but it’s not fixing the problem. Adding more refrigerant doesn’t fix the problem either. It’s just prolong the inevitable and wasting money.

R-1234yf Price Per Pound

Ok, now we are ready to take a look at the price per pound of 1234yf. First, let me paint a picture for you. Let’s say the air conditioner on your new vehicle went out and you just went past the warranty period. What can you expect repair wise? Well, you will need to repair and replace the part that failed but you will also most likely need to have the refrigerant recharged for your vehicle. But, what price should you pay?

I could tell you the price today, which I will in a bit, but I will also give you kind of a cheat sheet that I like to use when gauging the R-1234yf market price. It’s so simple. All I do is just go to Ebay.com and search for R-1234yf cylinders.  By doing this I can see what the going rate is per pound of R-1234yf. As I write this article today I can see that R-1234yf is priced between six-hundred and seventy to seven-hundred dollars a  ten pound cylinder. Now, let’s do some simple math to get your price per pound. Let’s take the higher amount of seven -hundred just to be safe.

$700 / 10lb cylinder = $70.00 per pound.

There you have it folks, $70.00 for one pound of R-1234yf refrigerant. Some of you may be having sticker shock right now, and yes I agree. It is a very high price especially when compared to R-134a. But, that’s just the way it is unfortunately. Now, please keep in mind that these prices CAN change. To give you a bit more help I have also included a feed from our Ebay partner below that shows you the current market price of R-1234yf:

Listings from eBay

CHEMOURS Dupont R-1234yf Opteon YF Auto Refrigerant HFO-1234yf 10LB Cylinder

Now each car is different and the amount of refrigerant that they need can be different as well. Some only require one pound and others upwards of eight to nine pounds. It is always best to check your owner’s manual or your dealership to see how much you need. In our example we’re going to call it three pounds of refrigerant to get a complete fill up of your vehicle.

3 pounds of refrigerant * $70.00 per pound = $210.00 for a complete fill up.

Conclusion

There you have it folks, that is the true cost per pound of R-1234yf refrigerant. I have said it already in the beginning of this article but I want to emphasize again that you may not pay the price we mentioned above due to your dealership’s markup. They deserve to make money as well and they deserve to be paid for their expertise. Just keep this article in the back of your mind so that when you do receive a quote you can ensure that you are receiving an accurate and fair price.

If you do find that you are being gouged and the dealership won’t budge then you may be able to run by a local auto-parts store to see if they have any yf cans in stock. If they do, then you could save some money by providing the refrigerant to the dealership.

EU Phasing out HFC

Over the last few years the European Union has experienced a rash of illegal refrigerants, refrigerant thefts, smuggling, and counterfeit refrigerants. Most of the time the refrigerants affected were R-22 or HFCs such as R-134a or R-404A. This time though things are a bit different.

Last month Honeywell worked directly with the Czech Republic’s Customs Office to seize a 1234yf shipment. As most of you know, Honeywell has a patent on 1234yf manufacturing. That means they are the only ones who can manufacture this refrigerant. (Chemours can as well, but that is because they are partnered with Honeywell.)  Besides these two companies no one else is able to legally manufacture 1234yf. That doesn’t stop everyone though, especially rogue companies found in China. Yes, this product that was seized came directly from China. Along with seizing the product Honeywell also took the step to file a suit against a Czech Republic refrigerant distribution company for attempting to distribute illegal product.

Earlier in the same month Honeywell did something similar to a Chinese manufacturer and distributor in Germany. And a few years back Honeywell partnered with the government out of Shanghai to sentence a man convicted of producing counterfeit 1234yf refrigerant. The man who was sentenced served nine months in jail and also paid a hefty fine for the violation.

Causation

All of the above cases were done to protect Honeywell’s monopoly on the 1234yf refrigerant. Some of you may not like that word monopoly, but that is what it is. Honeywell not only invented and patented this refrigerant but they also pushed and lobbied to have it adopted in every new vehicle across the globe. As the years go by Honeywell’s slice of the automotive refrigerant market gets larger and larger as R-134a applications begin to retire.

In Europe it has already happened. As of 2015 no newly manufactured vehicles can use R-134a. That leaves vehicle manufacturers with one of two options. They either use 1234yf or they use the experimental R-744 applications like what Daimler is doing. Most companies opt for 1234yf as it is the easier choice.

Since Europe started this conversion a few years ago it is only fair to have the first waves of counterfeit product arrive there. The price per pound on yf is quite expensive. Here in the United States it is about sixty-five dollars a pound. If we compare that to R-134a’s price per pound of three dollars we can begin to see why counterfeiting has begun. Now, I don’t know the markets over in the European Union, but I imagine yf is just as high if not higher over there. It is only natural for counterfeit product to show up.

Conclusion

There is only one real way I can see this counterfeiting to stop. Sure, Honeywell can keep playing whack-a-mole with these Chinese counterfeiters but it is not addressing the root of the problem. A counterfeit market typically exists because the price point is too high or the availability of the product is too low. By Honeywell addressing these concerns they could very well stop the counterfeit market in it’s tracks. But, that also means that Honeywell may have to lower price on their prized 1234yf refrigerant.

Over here on the Americas’ side I do not believe we’ve seen this problem yet on 1234yf. Yes, we’ve had our share of counterfeit products but that is still mostly HFCs and R-22. As the market for yf grows here we may very well have the same problems the EU is having. Remember, that when purchasing refrigerants to always ensure you are buying from a reputable supplier.

By now we all know that R-134a is on it’s way out. It has already been phased out on new vehicles in the European Union for years now. While there was a planned phase out date here in the United States of 2020 (2021 Model Year) by the EPA, it was overturned earlier this year by a federal court. The phase out is still coming though and some States (California and New York) have already announced they will mandate the 2020 deadline even if the EPA does not.

The problem we now have though is the price of 1234yf. Originally, we heard from the manufacturers that the price was so high due to development time and lack of resources to manufacture the product. But now, years have passed and fully functioning manufacturing plants have been opened. Honeywell opened one up in Louisiana and Chemours broke ground on theirs over a year and a half ago in Texas. That isn’t even mentioning the plants in China.

We would think that the price would begin to come down but here we are in 2018 and we are still looking at around seventy dollars a pound wholesale. That is NOT even mentioning the cost to the end user. If we check on E-bay or Amazon we’ll find cans of 1234yf selling for forty or fifty dollars per eight ounces. Let’s look at R-134a pricing now. If we go to Amazon.com we can buy three twelve ounce cans for less then twenty dollars.

Now let’s really do some math. Most cars take anywhere from two to three pounds of refrigerant. Let’s say, for whatever reason, our compressor has cracked and we have lost all refrigerant in the system. We need a new compressor and a complete recharge. Let’s look at the two different refrigerants and what the predicted cost would be to repair at a dealership.

R-134a

For argument’s sake let’s call a new A/C compressor around two-hundred dollars. So, we have the new compressor and the two pounds of refrigerant to fill up. Using the R-134a price we mentioned above we can figure out what the approximate resale price would be. If we break down that twenty dollar price on Amazon by can, then by ounce, and then multiply the ounce price by sixteen ounces we get the price per pound. In this case the price we get is just shy of nine dollars per pound.

So, for this repair we would be looking at:

  • $200 for a compressor
  • $18 for two pounds of R-134a refrigerant
  • $100 for labor.
  • $318 for your grand total to get your AC running again.

R-134yf

Now, going through the same scenario that we laid out above, let’s do the math with the 1234yf refrigerant. The A/C compressor will still be two-hundred dollars. The price we mentioned earlier on 1234yf was around forty-five dollars per eight ounces. Let’s take that number times two to get our per pound price of ninety dollars. Now let’s figure the repair bill:

  • $200 for a compressor
  • $180 for two pounds of 1234yf refrigerant
  • $100 for labor.
  • $480 for the grand total of the repair.

Difference

Obviously, there is a large disparity in price here between the two refrigerants. So large in fact, that 1234yf is ten times the price of R-134a. In this example the customer is paying one-hundred and sixty-two dollars more to repair their air conditioning system and that is assuming that the dealership won’t mark up 1234yf at a higher percentage then they do R-134a.

This difference is causing a lot of gripe and complaints here in the United States. Over in the European Union it isn’t as big of a problem as the price of R-134a has gone up to extreme levels due to the mandatory phase down and phase out of the HFC refrigerant. So, the price disparity between the two refrigerants isn’t as dramatic.

In the US though things are different. Consumers have been paying dirt cheap refrigerant prices for decades now and they are used to it. The moment someone gets one of these high priced repair bills on a faulty yf system they are going to be in for a shock. I can’t even imagine what will happen when refilling a larger vehicle like a semi-truck. I believe this cost difference is what is causing some users to ‘retrofit’ their yf systems back over to R-134a.

Yes, you heard me right. There are quote a few people doing this today. In fact, I found a video about a month ago that gave viewers a ‘How To Guide’ on switching yf over to R-134a. The video has since been taken down (Smart of the creator), but my article can be found by clicking here. This conversion is not only risky to your car and it’s air conditioning components but it is also against the law.

Yes, that’s right folks. This isn’t just about the environment. If you convert your vehicle over like what was done in this video then you are actively breaking Federal Law under Section 203 of the Clean Air Act. What was done in this video is known as ‘tampering’ with a vehicle’s emissions’ control device.

“According to MACSWorldWide.com, ‘Any person other than a manufacturer or dealer who violates the tampering prohibition is subject to a civil penalty of not more than $2,500 per violation.'”

Conclusion

If the price doesn’t come down on yf then I can foresee a lot of these do-it-yourself conversions or retrofits back over to R-134a. While this is illegal, the risk of doing it is so minimal that I can see a lot of folks doing it already today. Heck, there are even conversion port adapters out there so that you can charge R-134a in your yf ports.

The only way I can see this getting better is if the price on yf begins to drop and drop significantly. I just don’t see this happening though as the price and market on yf is controlled by two companies: Honeywell and Chemours. They have a monopoly on this refrigerant and I do not see them giving up their cash cow, especially when it’s just starting to get good as more and more vehicle manufacturers are beginning to switch over to yf.

The other option is if yf price doesn’t go down then the price of R-134a will need to go up, and up dramatically. Maybe, once we get closer to the 2020 deadline and more States phase out 134a we will begin to see the price rise enough to make yf look more attractive. For now, it seems we are stuck with the high price of 1234yf refrigerant.

RefrigerantHQ

Hello everyone! I hope your Labor Day is going well. We just got back from our city’s parade and I’ve got a few hours before our barbecue so I thought I’d take some time and get an article out there. I’m going to preface this article with the disclaimer that this is an opinion piece. Take it how you want, but it has been on my mind over the past year or so.

As we all know refrigerants have been phased out or phased down for decades. We started it way back in the early 1990’s with R-12 and other CFCs. Then we focused on HCFCs and now the world is looking at HFCs. With CFCs and HCFCs the goal of the phase out was to stop using Ozone damaging refrigerants. These refrigerants contained Chlorine which did not break down in the atmosphere and ended up harming the Ozone layer.

HFCs were the replacement for these Ozone damaging refrigerants. HFCs did not contain Chlorine and did not harm the Ozone layer. They were also non-flammable and non-toxic. Yes, I am aware there are always exceptions out there, but the most commonly used HFC refrigerants were non-flammable and non-toxic. These HFCs seemed to be the perfect substitute for HFCs and HCFCs.

Fast forward to the present and the world is now looking to phase down or phase out HFC refrigerants across the globe. This time though instead of them damaging the Ozone these refrigerants are contributing to Global Warming. Refrigerants are measured on a scale known as Global Warming Potential, or GWP. The zero scale for GWP is Carbon Dioxide (R-744) with a GWP of one. Popular HFC refrigerants, such as R-134a, have GWP as high as one-thousand four-hundred and thirty. There is an obvious problem here and the continued use of HFC refrigerants will speed up Global Warming. The question now though is what alternatives are out there?

Natural Refrigerants

For a lot of companies and countries the answer has been Hydrocarbons such as R-717 and R-290. These natural refrigerants have a very low Global Warming Potential and they do not deplete the Ozone layer. In fact, R-717 is widely seen as one of the most efficient refrigerants out there. Both of these refrigerants are great for the environment. The downside though is that these refrigerants can be dangerous.

Yes, just like with anything, if the refrigerants and machines are handled correctly and maintained properly then there is little chance of problems, but the chance still persists nonetheless. Let’s look at R-717, or Ammonia, as an example. Ammonia is a great refrigerant but it is toxic if inhaled. In today’s world it is mostly used industrial refrigeration such as meat packing plants and in ice rinks. When a leak does happen it can be deadly. Notice, how I said when? Ammonia leaks occur quite frequently across the Americas. There was a particularly bad one around one year ago in Canada that ended up fatally harming three workers. (Source) When an Ammonia leak occurs an evacuation has to occur. Depending on the size of the leak the evacuation could be a couple of blocks surrounding the facility. It can be that dangerous.

The alternative for Ammonia based systems was R-22. In the 1980’s and 1990’s companies could pick between these two refrigerants for their plants. (Yes, there were more, but I believe these were the main players.) The choice for R-22 is now gone due to the phase outs. Depending on the application, some were using R-134a as an alternative to Ammonia. But now, that too, is being phased out. While R-22 and R-134a were damaging the Climate they were safe. If a leak occurred it wasn’t the end of the world.

Now with the shrinking list of alternative refrigerants more and more companies are leaning towards Ammonia. Yes, there are new HFC and HFO alternatives being developed by Chemours and Honeywell but these have not been perfected yet. You may get one that has a low GWP but has a higher flammability rating. Or, you may get one that still has a somewhat high GWP and it just wouldn’t make sense to base a new machine off of a refrigerant that is only going to be around for a few years.

R-290, or Propane, has a similar story. While yes, it’s not near as deadly as Ammonia, it still has it’s risks. Instead of toxicity being a problem we now have to deal with flammability and flame propagation. If an inexperienced technician attempts to work on an R-290 unit and is not sure what they are doing they could end up igniting the refrigerant. (The worst is the guys who smoke when working on a unit.)

Now picture this, what if we start using R-290 in home based air conditioners? It doesn’t even have to be a split system, it could be a mini-split or even a window or portable unit. Let’s say Mr. Homeowner, who has no idea what he’s doing, decides to tamper with the unit because it’s not blowing cold air. Maybe he thinks it just needs ‘more Freon.’ If the unit was using Puron then the homeowner would recharge, waste his money, and think he did some good. However, if the unit contained R-290 the results could be far worse.

HFOs and Alternative HFCs

In my opinion, HFOs are much safer then Hydrocarbons, but there is still that safety risk out there. Let’s look at everyone’s favorite HFO target, 1234yf. Now, I know this horse has been beaten to death, but I’m going to bring it up one more time. YF is rated as an A2L from ASHRAE. That 2L means that YF is flammable and has a chance to ignite. What kills me here is that there was such a push to get YF rolled out to new vehicles that instead of rating it as a standard A2 refrigerant they instead created a whole new flammability called 2L. (Lower Flammability.) So, they’re admitting to it being flammable, but only slightly.

The whole controversy on YF started years ago when the European Union was looking for a suitable alternative to R-134a. There were hundreds of tests conducted across Europe and the World to view the viability of 1234yf. In one of these tests the Daimler company out of Germany found that after the vehicle suffered an impact and the compressor cracked open the HFO YF refrigerant ignited when it was exposed to the hot engine. (For more on this check out our YF fact sheet by clicking here. The video of the ignition is at the bottom.)

Needless to say, this test result shocked Daimler and they published their findings to the world. The other companies and countries stated that Daimler’s test could not be reproduced and that it was a non-issue. The world moved forward with the somewhat dangerous 1234yf. Daimler, being the innovators they are, decided to instead move forward with a completely different automotive refrigerant, R-744.

While 1234yf is by far one of the most popular HFC alternatives on the marketplace today there are others that have similar problems. One that comes to mind right away is R-32. R-32 is an HFC refrigerant that is beginning to see more popularity for it’s usage in home and commercial air conditioners. R-32 is an alternative to the standard R-410A that is found in most home units. The goal of R-32 was to reduce the GWP number when compared to R-410A. 410A has a GWP of two-thousand and eighty-eight while R-32 has a GWP of six-hundred and seventy-five. This is a significant reduction, but the GWP is still quite high when comparing to Hydrocarbons or HFOs. Another very important point is that R-32 is rated as an A2 refrigerant. There’s that 2 again. 2 means flammable except with this one we don’t even get the L for lightly flammable.

So again, I’m going to illustrate the similar scenario we mentioned above. Picture a homeowner, who doesn’t know what they are doing, trying to either retrofit his existing R-22 over to R-32 or perhaps he just wants to recharge his R-32 machine. Without the proper training and knowledge this can end in disaster.

Conclusion

So, now here we are sacrificing technician and public safety for the betterment of the Climate and environment. I understand that Global Warming is a crisis and that it needs to be dealt with, but is it really worth increasing possible risk and danger of everyday workers and people? It appears that in everyone’s haste to move away from HFC refrigerants and to save the environment the thought of safety has taken a backseat.

I mean, if we wanted to get really aggressive in the fight against climate change why not start using Ammonia in nearly every application? After all, it has a GWP of zero and is extremely energy efficient. (I’m being sarcastic here, if you couldn’t tell!)

A reader reached out to me today and told me that I had to watch a YouTube video. I pulled it up not really knowing what to expect. It definitely surprised me. The video is a do-it-yourself guide on how to convert your vehicle’s R-1234yf system over to R-134a. Yes, you read that right. I didn’t have that backwards. We have end users actively converting HFO systems back over to HFCs. I am sure most of us knew this would be happening on one off bases here and there but I didn’t expect to see a full do-it-yourself guide for everyone to watch and learn.

As most of you know, I began my career in the heavy-duty diesel industry. I remember back in 2007 when a new regulation went into effect for our trucks. All new vehicles were to be equipped with a Diesel Particulate Filter, or a DPF. Along with that you had a new fluid to add to your vehicle every so often called Diesel Exhaust Fluid. The point of this was to reduce the pollutants of semi-trucks that move all over the country’s roads. (After all, trucking is the life blood of the country.) While most fleets adapted to the change without issue there were guys out there, mainly owner-operators, that decided they didn’t like the DPF on their new truck. These guys came up with their own work-around that completely bypassed the particulate filter. It wasn’t legal, it wasn’t right, and it caused a ton of damage to the vehicle. But hey, they got their work around and got to do it ‘their,’ way.

We’re seeing a very similar thing here. People assume that R-1234yf and R-134a can be interchangeable. Yes, the pressures between the two refrigerants are very close to each other, but they are NOT exact. Click here to see a pressure comparison chart, courtesy of Lexissecurities.com. (Third page down) As you can see, the two refrigerants meet at thirty degrees Celsius, but after that they differ. Like with any air conditioning equipment the parts on your 1234yf vehicle are specifically manufactured to take 1234yf and no other refrigerants. Contaminating your system with a foreign refrigerant will at best case shorten the life of your compressor and other components. At worst, it will permanently damage your system causing an entire replacement.

When watching this video you’ll notice that he had to get a specific adapter just so he could insert the R-134a refrigerant into the system. This should have been a red flag. There is a reason why there are two different fittings between R-1234yf and R-134a. It is to prevent accidental contamination. I’m not sure why these adapters exist, but there must be a market for them or else they wouldn’t be found in auto parts stores or online. On the upside here, in this video the narrator did go through the trouble of vacuuming out the remaining R-134a from his system. So, we don’t have a contamination of mixed refrigerants… we just have all of the wrong refrigerant.

The video in question can be found below:

The Why?

Now there is one main reason for someone to do this: Money. Yes, it’s all about money and savings folks. R-1234yf is not easily found in stores at this time. Yes, it is available at online sites like Amazon.com and also through certain auto-parts stores but it is hit and miss. While the availability is a problem it is not the main gripe from end-users. R-1234yf is significantly higher in price then it’s predecessor R-134a. Let’s do a comparison real quick just to show the price difference. We’ll use Amazon.com as a point of reference just to make things easy:

  • R-134a: Three twelve ounce cans are for sale right now at $19.95. (Price can change at any time.) Let’s do some math now and break this down by price per ounce. $19.95 / 36 ounces = $00.55 per ounce for R-134a.
  • R-1234yf: Four eight ounce cans are for sale right now at $168.99. (Price can change at any time.) Let’s do some math now and break this down by price per ounce. $168.99 / 32 ounces = $5.28 per ounce for R-1234yf.
  • That is an eight-hundred and sixty percent increase in price between the two refrigerants.

Now, we can begin to see the end-users’ reasoning here. That is one hell of a price increase. Now if we couple that with the fact that not many stores handle 1234yf we find that most car owners end up having to go to the dealership for air conditioning repairs. I can only imagine the mark-up on 1234yf. Ok so, we understand the end-users reasoning but now we need to look at the consequences of converting a system over to R-134a.

Consequences

As with any action there are always consequences. In the case of this moving a vehicle from 1234yf over to 134a we have two distinct consequences:

The first is that by doing this switch you are actively harming the environment. The point of 1234yf is to reduce the overall Global Warming Potential (GWP) of vehicles and the refrigerants that they use. R-134 has a GWP of fourteen-hundred and thirty times that of Carbon Dioxide. Inversely, R-1234yf has a GWP number of four times that of Carbon Dioxide. Beginning to see the difference here? If you switch your unit back to 134a you are actively harming the environment.

The second reason, and the one that will most likely get everyone’s attention, is the Federal Government. Yes, that’s right folks. This isn’t just about the environment. If you convert your vehicle over like what was done in this video you are actively breaking Federal Law under Section 203 of the Clean Air Act. What was done in this video is known as ‘tampering,’ with a vehicle’s emissions control device.

According to MACSWorldWide.com, “Any person other than a manufacturer or dealer who violates the tampering prohibition is subject to a civil penalty of not more than $2,500 per violation.” 

That is quite the fine and if you get caught doing this that extra mark-up at the dealership might not seem so bad. Also, see the below excerpt from the Environmental Protection Agency’s website. Trust me in saying this folks, the Federal Government does not fool around with this stuff. Ask yourself is it really worth it?

Tampering. The CAA prohibits anyone from tampering with an emission control device on a motor vehicle by removing it or making it inoperable prior to or after the sale or delivery to the buyer. A vehicle’s emission control system is designed to limit emissions of harmful pollutants from vehicles or engines. EPA works with manufacturers to ensure that they design their components with tamper-proofing, addresses trade groups to educate mechanics about the importance of maintaining the emission control systems, and prosecutes cases where significant or imminent harm is occurring. – EPA.Gov Source

Conclusion

I am hoping that this isn’t the start of a trend. Remember folks, that the whole reason we’re moving away from R-134a is to reduce Greenhouse Gases and slow Global Warming. By having end-users actively retrofitting their systems back to R-134a we are defeating the entire purpose of this phase down. Now, I wasn’t really around for the whole R-12 phase out. (I was only seven in 1993.) so I don’t know if this was common place in the early stages of the R-12 phase out or not. Regardless, it needs to stop.

I’m hoping that writing this article we can grab the attention of other users out there who are thinking about doing this conversion and steer them away from the cliff. Sure, you might save a little bit of money upfront but you have to ask yourself is it really worth it in the long term? Also, maybe it’s time we get some 1234yf recharge kits out there so that we can prevent these types of retrofits in the future. If they have access to a recharge kit then maybe they will not go down the path of 134a.
