what type of refrigerant is in my car

There are two types of refrigerant that are commonly used in cars today: R-134a and R-1234yf. R-134a replaced the refrigerant commonly known as "freon" and is the most common refrigerant used in cars today. R-1234yf is a newer and more environmentally friendly refrigerant than R-134a. If you are unsure which refrigerant your car uses, you can check under the hood for a label that will indicate whether your car uses R-134a or R-1234yf. If your car was manufactured after 2014, it is likely that it uses R-1234yf refrigerant. It is important to note that different types of refrigerant cannot be mixed, and unique machinery is required to service a vehicle for each type of refrigerant inside.
