When did auto ac change to R134a?

R-12 is no longer used or produced in many countries and remaining quantities have skyrocketed in price. Since then, the industry standard has been R134a, which is an efficient replacement.

Can you put 134a in an R12 system?

No. Federal law prohibits topping off an R12 system with a different refrigerant. Or you can convert the system using one of our R134a retrofit kits, that will allow you to now add 134a refrigerant to your automotive air conditioning system.
