How Dangerous is Fake Car A/C Refrigerant? Let's Find Out!

Fun fact: "Freon" is DuPont's registered trademark for R12. If it isn't R12, made by DuPont, it isn't "freon"

I own an HVAC company and I'm surprised how well and thorough you did with this video. I shouldn't be, because you're always thorough, but I never expect anyone to grasp refrigeration very well. Great job! I didn't even realize there were a bunch of 134a replacements on the market. Good to know. Replacement refrigerants usually work fine, but I avoid them when I can. Also, I'll ask again and hopefully one day you'll be able to get to it, but- testing coolant additives would be awesome. Those additives that are supposed to make your cooling system run cooler like Royal Purple's Purple Ice, Water Wetter, etc.

Today I learned how to properly recover refrigerant. Thanks for unveiling another mystery of the trades!

This was not a test of R-134 replacement refrigerants … it was a detailed course in AC servicing! Bravo, great job!

My grandpa used to charge his AC system with propane. When I got my first square body truck it had AC but didn't work, he said "oh just needs charged" I didn't think anything of it he charged it and it worked great, I drove that truck for almost a year when one day we were talking and he asked how my AC was doing I said still works great he replys with " good ol propane" I said WHAT!?! He then proceeds to tell me that's how he's always charged ac systems! Sorry papa I had to tell the story, RIP 🙏

Literally one of the best examples of correctly using a refrigerant recovery machine on YT

To be fair, the R134a Replacement Refrigerant has R134a written on it with huge letters despite not being that stuff at all. Unlike ZeroR, the replacement refrigerant has purposefully been designed to deceive customers looking for actual R134a.

I like the dude’s commitment to a task….

Here's a list of the products tested in the video. More details in the video description. Thank you!

Not only a great video about how an AC system works, but also a PSA on refrigerant substitutes and the dangers involved with using them.
