What Type of Refrigerant Should I Use When Replacing an Air Conditioner?

When it comes to replacing an air conditioner, it is important to know what type of refrigerant to use. Ozone-friendly refrigerants, such as R-410A, are now the standard for residential air conditioning systems. If you have an older system that uses HCFC-22, an HVAC contractor may be able to retrofit the air conditioner for use with the R-410A. The technician will determine the type of refrigerant your air conditioner uses so that it can be refilled with the appropriate type.

The technician will recommend if your air conditioner uses R-22 or R-410A refrigerant. You can thank your air conditioner for having a cool and comfortable home during the hottest days of the year. There are actually three different types, and using the wrong one can damage the air conditioner because they are not interchangeable. One way to know what refrigerant your air conditioner needs is to check the large label or plate on the compressor or evaporator, which will indicate the refrigerant you need.

All centralized air conditioning systems use several refrigerants to remove heat from the air and cool the space. On the other hand, if you don't feel comfortable replacing it yourself, you can always hire a professional like Dependable Heating & Air Conditioning to do it for you. They specialize in replacing outdated refrigerants with new types of environmentally friendly ones. If your air conditioner expels hot air, you may need more refrigerant, but you'll need to fix the leak first.


(also known as Freon 2) is a CFC-containing refrigerant that was standard in air conditioners from the 1960s to the 2000s.

This basic principle is what allows warm air in the house to pass into the air conditioning system and be replaced by cold air.
