What Are The Best R-134a AC Recharge Kits?

Hello ladies and gentlemen and happy Sunday to you all! Over the past few days here at RefrigerantHQ we have been taking a look at the various R-134a AC recharge kits on the market today. These products are typically used during the summer months when a customer gets into their car and realizes that their air conditioner is on but it is no longer blowing cold air. Typically this happens because your AC system is either running low or has lost all of it’s refrigerant. What these AC recharge products do is simply recharge your AC system with more refrigerant. The added refrigerant should be enough to get your car blowing cold again.

Now, there are a variety of R-134a AC recharge kits out there on the marketplace. The question is which ones to buy and which ones are worth your money? Should you go with the cheaper version, or the more expensive? What brand should you get? This buyer’s guide will give you an idea of what to expect when purchasing and using recharge kits as well as how to use them.

Know Before You Buy

A lot of you may already know this but I would be amiss if I didn’t mention it. Before we get onto the top products I want to point out that these AC recharge kits are not a miracle worker. Heck, most of the time they aren’t even a fix. What these recharge kits do is take a problem that you have with your car’s air conditioning system and push the problem on down the road.

Your AC system rather it be on a car, house, or freezer all work relatively the same way. The refrigerant goes through an endless cycle moving back and forth between gas and liquid and liquid to gas. The system is completely sealed and no refrigerant should be coming out of it. So, in a perfect world you should never run out of refrigerant. But, as we all know the world isn’t perfect and things break, hoses crack, o-rings crumble, and so on and so on. When this happens your refrigerant begins to leak out. The more refrigerant that leaks out the less potent your air conditioner will be in the dead of summer.

Now what these recharge kits do is pump your system full of refrigerant again. So, you have a leak where your refrigerant escaped out of and if you use a recharge kit you are just dumping more refrigerant into your system. Depending on your leak this could be a good thing or a bad thing. If you have a tiny crack in one of your A/C hoses that barely leaks then an AC recharge kit will be perfect for you. You could recharge it in March and have it last the whole season because the leak is so small. But, if you have a very large leak, or worse, a major part failure then these recharge kits will not work for you. You could recharge your car today, have it blow cold air, and then come back a few days later and all of your refrigerant is gone again. Not a good deal.

So, the point I’m trying to make here is just know that these recharge kits aren’t a miracle worker. Yes, they’ll work in some cases, but not all. Alright, on to the review!


One last thing that is worth mentioning is that while you may see different brand names and product names below these products are all owned, manufactured, and produced by the same company known as IDQ Incorporated. Upon doing my research on these products it looks like the IDQ company has carved out their specific niche and now have nearly one-hundred percent of the do-it-yourself vehicle air conditioning repair sector. The company has been in business for over forty years and through out all of those years they have been dedicated to providing products for the weekend warrior mechanic as well as the seasoned service tech. These guys know what they are doing and provide customers with a good quality product. That being said all of these products below are from said company even though the brand names may be different.

Good, Better, Best

Alright folks onto the best recharge AC kits on the market today. When I do a best of article I always like to organize things by the Good, Better, Best technique. This process and way of organizing things has stuck with me for nearly ten years. It was how my boss, back when I worked at Kenworth, taught me. If you overwhelm someone by offering them dozens and dozens of choices they will most likely shut down and stop listening to what you have to say. Instead, the smarter way to do it is to offer the customer three main choices: Good, Better, and Best.

The good category offers customers a viable and working product that will get their job done at a low price point. The better category is, you guessed it, the next step up. With better the customer gets a little more quality but also ends up paying a bit more. Lastly, the best category is reserved for the best product on the market. That means top quality and top price. Now, depending on who you are and what your mindset is it is up to you what you decide to purchase. Are you a Good, Better, or Best guy? I hate to say it but I’m a Good guy… I’m trying to break that habit and move up to Better!

Good – Arctic Freeze Ultra Synthetic Automotive Refrigerant 134A (22 oz.)

Arctic Freeze Ultra Synthetic Automotive Recharge


This arctic freeze recharge kit ranks in our ‘good’ category. It provides you with everything you need to recharge your system. It is definitely on the cheaper side of recharge kits but it will still get the job done. This is the product I like to recommend as a ‘trial’ recharge. If you are unsure if you need to take your car to the shop or not then give this product a try and see if you can solve the problem yourself, or at least put it off until next season.

Better – Interdynamics MAC-134 EZ Chill Refrigerant Refill

Interdynamics MAC-134 EZ Chill Refrigerant Refill with Charging Hose and Gauge - 18 oz.


Product Review

This was a tough decision between the better and the best categories. Both of these products are great and will give you that much needing cold air. Coming in at the Better category is Interdynamics MAC-134 EZ Chill recharge kit. This product comes with eighteen ounces of refrigerant, a built in gauge, a hose, and a coupler to fit your low side port. You also get a built in leak sealer to help prevent any future problems that can come up down the road.

Best – A/C PRO ACP-100 Professional Formula R-134a

A/C PRO ACP-100 Professional Formula R-134a Ultra Synthetic Air Conditioning Refrigerant with Reusable Dispenser and Gauge - 20 oz.


Product Review

The A/C Pro ACP-100 is the best recharge product out there today. It is a bit pricier than the EZ Chill version but there are some benefits to this price increase. With the ACP-100 you get twenty ounces instead of the eighteen that we mentioned above on the EZ Chill. Along with that you get an extra long twenty-four inch hose to help you reach those cars with the ‘strange’ designs. To top it off the coupler on this product is easier to attach. Instead of having to manually pull the collar up on the coupler like you do with other products all you have to do is just push the coupler onto the port and it will pop right on. I’m always a big fan of the easier the better and the ACP-100 does just that, it makes things easy.

Remember how I said that these recharge kits are a temporary patch and don’t actually solve anything? Well folks the Interdynamics AFK-11CS actually takes a step in that direction by providing you with UV dye mixed in with the refrigerant as well as a UV light pen that you can use to begin scanning for the source of the leak after you have charged your system. This feature right here, along with giving you two cans of refrigerant, is why the AFK-11CS Arctic Freeze falls into our ‘Best’ category. You get two cans of refrigerant, UV dye and pen, and ALL of the other features and benefits that the other recharge kits have. The only real downside to this product is the price. As you can imagine since this product falls into the best category it is going to be quite a bit more expensive then the other products on the market we mentioned above.


Regardless of what kind of consumer you are any of the above three products will aid you in getting your car blowing cold air again. While some are better than others it is important to note that even the product in the ‘Good’ category is still perfectly viable solution to fixing your air-conditioning system. Also, I’ll say it one more time. These charge kits are not a cure all and most of the time they do not fix your problem. Instead, they delay your problem by adding more refrigerant to your system. So, while this may work for you today you man end up feeling warm air blowing in your face a few weeks later. It is impossible for me to tell if you have a minor leak, a large one, or a failed compressor.

Lastly, if you need some help or am not sure how to use these kits please check out our do-it-yourself guide that we put together a few days ago. It can be found by clicking here.
