Is freon the same as R134a?

Note that R134a is also sometimes called “Freon,” even labeled as such on the can, so it’s best to be clear and use the names R12 and R134a. R134a systems operate at higher discharge-side pressures than R12, which can cause compressor seals to leak. Bottom line, R134a simply doesn’t cool as well as R12.

What type of freon do I need?

So, a good rule of thumb is if you own a vehicle that is newer than 1995 your engine should take R135a refrigerant, but if you have a vehicle older than 1995 you are going to be purchasing R12 refrigerant.

What happens if you mix R12 and R134a refrigerants?

R134a systems work at higher discharge-side pressures than R12 systems, which could lead to compressor seals leaks. Additionally, since R134a is composed of much smaller molecules, it has a greater chance of leaking from an R12 system.

How do I change from R12 to 134a?
