Jaki czynnik do klimatyzacji wybrać – R134a czy R1234yf?

Which refrigerant to choose for air conditioning – R134a or R1234yf?

Choosing the right car air conditioning refrigerant is a key issue when servicing or refilling the A/C system yourself. The two most commonly used types are R134a and R1234yf. Which one is right for your car? Check before you refill the air conditioning.

R134a – for which cars?

The R134a refrigerant was the standard in car air conditioning for many years. You will find it in most vehicles produced up to around 2016.

Characteristics of R134a:

  • used in cars produced from the 1990s to around 2016,

  • widely available and popular,

  • compatible with most older air conditioning systems.

If your car was produced before 2017, it is very likely that the appropriate one will be R134a type air conditioning gas.

R1234yf – refrigerant for newer cars

Since 2017, car manufacturers in the European Union are required to use R1234yf refrigerant.

Characteristics of R1234yf:

  • used in newer vehicles (from around 2016/2017),

  • a different type of service connector than R134a.

If you have a newer car, you probably need R1234yf type refrigerant.

How to check which refrigerant is in your car?

To choose the right air conditioning refill kit, check:

  1. Information sticker under the hood (with R134a or R1234yf marking).

  2. Vehicle user manual.

  3. Car production year.

Attention! Remember not to mix R134a and R1234yf refrigerants.

Can you refill the air conditioning yourself?

Yes. Special kits are available for self-refilling car air conditioning – separately for R134a and R1234yf. Just choose the right version and check the pressure in the A/C system.

Refilling the air conditioning yourself is a quick and economical solution, especially when the problem is a low refrigerant level.
