ZeroR® AC Refrigerant | R134a Replacement | 3 6oz Cans for AC Recharging

These are perfect and way cheaper than buying them at the store. Great deal and I will be purchasing more when needed due to a slow leak in my AC system.

Very user-friendly only had to use half a bottle to get my AC cold Where my gauge was for the AC technically only needed half a bottle to fill the bought three just in case

Easy refills

It does exactly what it says it's going to do. Results might vary according to your system of course but it works well enough for me and it hasn't ruined anything yet so 4 stars from me for now

I have used HC12a products before with success. This was not on par with my past experiences. Unfortunately, I bought quite a bit of this product for a project of mine, and it's non-returnable. I feel that I have truly wasted my money. I will not recommend THIS brand, but there are others that do exactly what they say, and have great support.I reached out to DIY Parts to ask for some guidance with one of the problems I was seeing, and didn't get any help. Granted, I have an R12 system (converted) but they weren't willing to provide any input. Additionally, I called their phone number several times and it just kept going to voicemail.I just cannot recommend this product to anyone. Don't take this low review as a poor reflection on other hydrocarbon-based refrigerants, but whatever this company is selling is not of equal quality.

Put a new compressor on my 2004 f150. Thought I was buying 134 but mistakenly bought this but decided to use it anyway. Worked far better than I thought it would. 2 cans and blowing really cold. Very satisfied.

I have been refilling automotive systems with HC refrigerants for around 15 years now with no issues at all and better performance out of the systems over the original R134a refrigerant (can't explain it since the boiling point is typically lower for R134a depending on the HC). I prefer to switch to these refrigerants when the system has developed a leak and pressures are low since you need to evacuate the system before filling with this product. I have always wondered why companies spend so much time developing systems for chlorinated and fluorinated compounds when hydrocarbons have been proven to do the job just fine without the ozone/greenhouse risk and have a flammability rating that is manageable. It's not like the government isn't pushing hydrogen everything to be the next "green" transition and it has some pretty serious flammability/containment issues of its own.

When's I put the in today air conditioning It did not work, still Blow out Hot air. So I gone to the store and brought the right one and behold Great air.
