A Brief History of Refrigerants

Updated: Aug 2

Most people don't realize it, but a vehicle's refrigerant is a very toxic chemical. So toxic, that venting refrigerants into the air is illegal!

Older refrigerants contained chlorofluorocarbons (CFCs). CFCs were so bad for the environment that 197 countries signed a ban on any product containing them in 1987. It even included hairsprays! You may know this ban as The Montreal Protocol.

This CFC-ridden refrigerant is called R12. For years, R12 was efficient and cheap. But it was destroying our ozone layer. The Montreal Protocol banned R12 from all new cars post-1994.

After R12, manufacturers switched to R134a. Most of you readers likely have R134a refrigerant in your A/C system. It is better for the environment, but it still isn't perfect.

Once R134a gets into the atmosphere, it takes a long time to break down. So a new rule got passed! As of 2021, all new cars have to have R1234yf refrigerant.

R1234yf refrigerant may be a mouthful, but it works the same as R134a refrigerant. The only difference is that it breaks down a lot faster in the atmosphere.
