Why It’s Important to Know If Your Ac or Heat Pump Uses R-22 Refrigerant

If your HVAC system was manufactured prior to 2016, it may use R-22 refrigerant to operate and to cool or heat your home. Up until 2015, manufacturers were allowed to make units that used R-22 (Freon), despite the fact that the use of this substance is being phased out in the United States.

R-22 Refrigerant Prices Skyrocket

Due to the decrease in availability of R-22, the price for this type of refrigerant is skyrocketing. There is a replacement refrigerant for R-22 being used in all new models, which is R-410A. It’s not as simple as using this new refrigerant in your existing system, though. Because these refrigerants aren’t interchangeable, it’s not recommended that these refrigerants are mixed.

Why R-22 Refrigerant Is Phasing Out

The U.S. agreed to phase out the production and import of the refrigerant starting in 2010. The EPA found that use of the substance was negatively affecting the environment by damaging the ozone layer. Since that time, the refrigerant has become increasingly more difficult to find.

What This Means for Your HVAC System

If your system runs on R-22, it’s likely to be expensive to recharge. At some point as supplies dwindle, your air conditioning repair company may not be able to access the substance to add to your system.

The lack of R-22 becomes problematic when your unit requires servicing. If you have a refrigerant leak, it’s going to become increasingly more expensive and difficult to have the refrigerant replaced.

How Can You Tell If Your System Uses R-22?

To discover what type of refrigerant your system uses, look at the label on the outdoor condenser. It will either say R-22, which may be called HCFC-22, or the newer type, which is R-410A.

What to Do If You Have a System Using R-22

If you have an HVAC system that uses R-22 refrigerant, it’s recommended that you have the system inspected and tuned up by an HVAC contractor. A qualified technician will determine if your system has any leaks.
