Does your vehicle AC have 134a refrigerant Here is how to tell

Whether you have an older car or a newer one there are many people that have questions about the type of refrigerant that they have in it. Although it may seem confusing at first, it really isn’t once you know the difference and what to look for. With a little detective work, you can know what type of refrigerant you have in your car, too.


There are two types of refrigerant that are used in automotive air conditioners. The first one is called R12, while the other one is R134a. They may sound just like similar part numbers, but there are actually major differences between them. For starters, R12 was the one that was used on older vehicles. It goes by the brand name of Freon and it earned a bad reputation when scientists found out that it was responsible for helping to deplete the ozone layer.


R12 is still used in some older cars, especially those that have not been converted to a more modern and environmentally safer system. R12 refrigerants were used prior to 1995, so older vehicles all had this as a standard fixture if the had air conditioning units. Since that time, some people have converted their air conditioning system, and cars produced after 1995 were all produced with R134, which is a refrigerant that is not believed to harm the environment.


To tell if you have R134a, start by considering the year of your vehicle. If you have a vehicle manufactured after 1995 then you should have R134a. If your vehicle is older you may still have R134a, it just depends on if it has been converted. To tell if it has been converted you can look for a sticker on the unit under the hood, which would indicate that it is R134a, and you can also look for R134a adapters, which would be located on the charge parts.


If you are still unsure what type of refrigerant you have, stop by a shop. Within minutes you will know what type of refrigerant you have, as well as what your options are if you need any service, or if you would like to make the conversion if you have an older model. Within minutes you can be on your way to refrigerant that is better for the planet!
