How Much Does It Cost?

Refrigerant is one of those things that no one really thinks about. People go throughout their days and it never crosses their minds. Why should it? It is one of those ‘hidden industries’ that no one really knows about. It is an inside club that only those within the industry are aware of. Regular people only become interested in the topic when it affects them. It’s human nature. The problem with refrigerants though is that it is such an ambiguous topic and there just isn’t that much content out there to read on it. So, when a homeowner is faced with a hefty repair bill how do they know they are being treated fairly? Or, if your vehicle’s air conditioning has quit working and you take it to the dealership how do you know you are receiving a market price for your refrigerant?

In this article we are going to provide you with links to our various price per pound articles for 2020. These are various articles here and that leads me to my first point. You may be under the misconception that there is only one kind of refrigerant. In fact there are hundreds of different refrigerants out there. If you look at this list from Wikipedia you can see exactly what I am talking about. While that list may seem a little overwhelming, I do have some good news.

Out of that large list of refrigerants there are only a select few that are widely used in today’s world. A good portion of the refrigerants in that listing have been phased out over the years for a variety of reasons. They could have been toxic, flammable, Ozone damaging, or global warming damaging. When it comes to repairing an appliance or vehicle in 2020 the number of refrigerants that your appliance could take are significantly lessened.

So, What Kind of Refrigerant Do I Need?

As I was saying above, there are a select few refrigerants that your appliance are using in 2020. In fact, there are five main refrigerants that you are going run into over and over again. They are your HCFC R-22, HFC R-410A, HFC R-404A, HFC R-134a, and the HFO R-1234yf. This definitely makes it easier to identify what refrigerant you need. But, in an effort to make it even simpler let’s take a deeper 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.


Ok folks, so after reading the above section you should have a very good idea on what kind of refrigerant that your appliance or vehicle takes. That being said, never guess as to what kind of refrigerant your system needs. That my friends is a recipe for disaster. You cannot mix refrigerants with other refrigerants. If you do so you will permanently damage your system. Think of it like putting diesel into a gas vehicle. You shouldn’t do it. You have to know what refrigerant your system takes before anything else can be done.

In recent years there have been pushes to phase out some of these refrigerants. In fact, R-22 is going away entirely on January 1st, 2020. Other refrigerants such as the HFC classifications may end up being phased out fairly soon. If you happen to see a refrigerant that your appliance is using and that it is NOT in this list please reach out to me and I will do some research and get it added to this listing.

Thanks for reading,

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:

[ebayfeedsforwordpress feed=”http://rest.ebay.com/epn/v1/find/item.rss?keyword=1234yf+refrigerant+cylinder+-%28can%2Crecovery%2Cgauge%29&sortOrder=BestMatch&programid=1&campaignid=5337389126&toolid=10039&listingType1=All&feedType=rss&lgeo=1″ items=”2″]

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.


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,

R-134a Refrigerant

One of my most visited articles this year was on the topic of the Environmental Protection Agency’s proposed phase down and eventual phase out of the HFC R-134a. This article is a few years old now and it was referencing the EPA’s SNAP Rule 20 and 21. These rules, which were issued in 2015, stated that R-134a would no longer be acceptable for use in new 2021 model year vehicles.

When I wrote that article everyone was under the impression that this phase out would come to fruition and auto-makers would be forced to switch away from R-134a just as they had done in the 90’s with R-12. There was very little debate on it, it was just the next logical step. However, the winds of politics changed a few years after the EPA announced their new regulations.

In the summer of 2017 a federal court overturned the EPA’s regulations stating that they had overstepped their authority. The argument was that the EPA was using authority granted to them by the Clean Air Act and the Montreal Protocol. Both of these refer to Ozone damage done by products that contain chlorine. Since HFCs contain no chlorine and do not harm the Ozone the EPA does not have authority to phase them out. HFCs do harm the environment, just not in the specific way that these documents lay out. It may have been a loophole, but the law is the law.

This was a surprise to a lot of folks and it caught many companies off guard. I know that courts are supposed to be impartial when it comes to politics but I find it an odd coincidence that a short while after Trump is elected we see this significant overturn in government policy. The court’s ruling voided the EPA’s SNAP Rule 20 and 21 regulations including the one on R-134a. So, as of 2017 there is NOT a scheduled phase out date for R-134a. When I initially heard about this ruling I had assumed automakers would take the easy route and continue the status quo with R-134a.

I was wrong. Over the years more and more makes and models are switching their new vehicles away from R-134a and over to the HFO 1234yf. Earlier this year I wrote an article that attempted to gather a listing of ALL manufactured cars and what refrigerant they are using for their 2020 models. This article took quite a bit of time as I had to dig through instruction manuals for each of these vehicles in an effort to determine the refrigerant they used. The article can be found by clicking here.

The results were rather astounding. If you look at the top fifty selling cars within the United States there are only fifteen using R-134a. That is a seventy percent market share and those numbers are growing with each passing year. Over the next few years there is a prediction that up to ninety percent of cars will be using 1234yf. There are a few reasons for this but in my opinion one of the biggest is that the European Union and other countries have already begun phasing out R-134a. The EU is using R-1234yf and R-744 in their newer vehicles. Perhaps, in an effort of engineering simplification these auto-makers have decided to bite the bullet and switch to 1234yf.

The other major reason for this is pressure from state and environmental groups. While the Federal Government doesn’t have a phase out plan for R-134a there are many states that do. These states makeup what’s known as the Climate Alliance. While not all of these states have announced an HFC phase out plan a good portion of them have. Some of the largest are California, New York, and Washington State. These states can have enormous sway with auto-makers. Just imagine if Ford could no longer sell their trucks in California or New York. That would be a huge impact. Why not make ALL of their vehicles compatible and just use 1234yf?


So, instead of the phase out that occurred with R-12 we have seen a phase out occur due to attrition. Over time the amount of cars using R-134a is going to shrink and shrink. Yes, it may take another ten years or so to get most of the R-134a vehicles off the streets but, in essence, the phase out has already begun. With all of the twists and turns the R-134a phase out has had it is somewhat ironic that we may hit the ninety percent 1234yf usage by the year 2021. While we may have not met the EPA’s goal entirely we are going to be darn close.

Before I close this article I did want to bring up one additional point. This is a question that I’ve had in the back of my mind when it comes to 1234yf. You see, I work in the heavy duty trucking industry. Think over-the-road trucks, dump trucks, water trucks, etc. Through all of this talk on phasing out R-134a for automotive vehicles I have seen very little, or in some cases nothing, when it comes to R-134a usage in truck classes six, seven, and eight.

I have seen the amount of R-134a a single truck dealership can go through in a year. The numbers can be staggering. The question I have is when will these truck OEMs begin to seriously look at 1234yf? Has Kenworth or Freightliner already begun looking? The only news stories I could find on it are three or more years old and reference the original EPA rule as gospel. If we’re going to phase out R-134a in automotive we have to phase it out in heavy-duty as well.

I wonder, when will these OEM behemoths make the move?

Thanks for reading,

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.


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.

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.

The chart below details the pressures and the saturation point, or boiling point, R-1234yf:

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. 

Thanks for reading,
