Your question: Do modern cars use Freon?

Vehicles manufactured before the 1994 model year used R-12 (also referred to CFC-12 or Freon). Newer vehicles rely on R-134a refrigerant, also known as HFC-134a.

Do new cars use Freon?

New cars can no longer use R-134a in their air conditioning systems, manufacturers have now switched to R-1234yf which has a much lower GWP.

Do cars still use Freon for air conditioning?

Freon is a brand name registered to DuPont, and it’s applied to quite a few different refrigerants, the most common of which is R-12. Once, this was the most common type of refrigerant used in automotive air conditioners, but it is being phased out.

Do they still use Freon?

To help protect the ozone layer, the EPA has mandated that the production of Freon be stopped by January 2020. The good news is that new air conditioning systems made since 2010 no longer rely on Freon. Most newer AC units use a refrigerant called R410A, or Puron.

What type of refrigerant is used in new cars?

The type of refrigerant used in automotive air conditioning systems is changing. Although R-134a refrigerant was used until recently in late model vehicles, most new cars and light trucks are now being equipped with A/C systems that use R-1234yf refrigerant.

What refrigerant is used in 2021 cars?

Beginning in 2021 all vehicles manufactured will be required to use the new R1234yf or Tetrafluoropropene refrigerant in their vehicles air conditioning systems. This new class of refrigerant was created in an effort to lessen the effects of leaking A/C systems to our environment.

Can R-134a be used in place of R1234yf?

The answer is yes, it will. This makes it simple. Service shops can stock one product, PN 702, and use it for any vehicle, whether it uses R-134a or R-1234yf.

Do cars need Freon?

Though many car owners think they need to recharge or “top off” their air-conditioning system with refrigerant on a regular or annual basis, that’s not the case. An A/C system is a closed system, and if there are no problems, coolant is not consumed by the vehicle, nor does it escape.

Do all cars use the same refrigerant?

The most common refrigerant is R-134A (or HFC-134a) however newer vehicles may use R-1234YF (or HFO-1234yf). Even still, some very old vehicles may also be using R-12 (or Freon). The easiest way to know is to check your vehicles A/C system nameplate under the hood.

Why is Freon banned?

Freon is a refrigerant chemical that was widely used in older residential and commercial cooling systems. R-22, the principle component in Freon, has been banned, along with other greenhouse gases, due to evidence that they damage the Earth’s ozone layer and contribute to global warming.

Is Freon being discontinued?

Freon, also known as R-22, will no longer be made or imported to the United States, starting January 1st, 2020. The Environmental Protection Agency said the odorless gas, which is one of the key refrigerants in air conditioners, is bad for the environment because it depletes the ozone layer.

Should I use Freon?

Never. An AC doesn’t “use up” refrigerant. So you should never need to recharge your air conditioner with more Freon—unless there’s a leak.

What happens if you mix R134a and R1234yf?

If you were to put R1234yf in a system designed for R134a, it looks like you’d end up with about a 10% loss of cooling capacity, but putting R134a into a R1234yf system would be a wash. It appears R1234yf oil is compatible with R134a (but not vice-versa), so shouldn’t be a problem there.

What year did they change Freon in cars?

Many collector car owners wonder what to do about their air conditioning (A/C) systems as ever-changing government regulations dictate the type of refrigerants allowed. In 1994, Freon, or R-12, was outlawed and replaced by R-134a and that is now being replaced.

What year did cars switch to R134a?

R-134a first began to see widespread usage in 1992 and took over the automotive market entirely in 1994. If you have a vehicle from 1994 or newer your air conditioning unit takes R-134a. It has been the standard automotive refrigerant for over twenty years.
