FAQ:

Q: Can a car be converted from R12 to R134a?

A: R12 to R134A Conversion There are two ways to convert the air conditioning of your vehicle to the R134A gas. One is the factory method, where you would need to replace the AC parts, and the other is to modify the existing components to use R134A.

Q: What should I do with my R12 compressor?

A: Make sure your AC compressor is in good shape, otherwise replace it. Flush your current system entirely of R12 without leaving any traces of the R12 in it. Instead of merely letting the gas out into the atmosphere, flush and recover the R12 for recycling purposes with a machine.

Q: What kind of oil to use in a R-12 retrofit?

A: Add the proper Ester or PAG oil to the condenser, compressor and evaporator if necessary. Ester oil is often recommended for use with retrofit systems because it can mix with any remaining traces of mineral oil or R-12 and still lubricate the system properly.

Q: Why is R12 used in air conditioners and freezers?

A: Because of the versatile nature of R12, it quickly became a refrigerant that used in air conditioners, refrigerators and freezers. This refrigerant is used in household appliances because its properties are relatively safe. This refrigerant was neither flammable nor toxic.
