1994Type #3: R12 — The Old and Busted One For many years, R12 was the automotive refrigerant standard. It was effective and cheap.

What year did Freon change in cars?

1994However, it was found that when a car emits R-12 Freon, it depletes the ozone layer. The Environmental Protection Agency outlawed ozone depleting substances in 1994 and, as a result, R-134a Freon is now used instead. If you own a car that was manufactured before 1994, you can have your A/C retrofitted for R-134a Freon.

When did they stop using r134a?

1990sUse of the ozone-depleting refrigerant, chlorofluorocarbon (CFC)-12, in new motor vehicle air conditioning (MVAC) systems ended in the mid-1990s in the United States. Since 1994, the most common refrigerant used in MVAC systems has been hydrofluorocarbon (HFC)-134a.

R12 fittings look like a tire valve stem, with threads on the outside. R134a fittings look like a air hose ‘quick connect’ fitting.

Do cars still use freon?

Cars used to use Freon as a refrigerant, but it’s no longer allowed to be made in the U.S., so modern cars use R-134 instead. Most vehicles don’t need refrigerant to be added more than every few years unless there’s a leak somewhere in the system.

Can a car lose Freon without a leak?

In a properly sealed system the gas can continue being compressed and released over and over, so long as it doesn’t leak out.

Can I mix r12 and 134a?

You cannot mix R-12 with R-134a, they are not compatible (and neither are the compressor oils used with them).

What is the best replacement for r12 refrigerant?

The best replacement for R12 is considered to be R-134a. The chemical name of R134a is tetrafluoroethane and it chemical formula is CF3CH2F. It is a hydrofluorocarbon (HFC) and has zero ozone depletion causing potential and very low greenhouse effect.
