What are refrigerants used for?

When combined with the compressor and evaporator of an air conditioning system, refrigerant can absorb heat from the surrounding areas and provide refrigeration.

Refrigerant is found inside the copper coils of your air conditioning system and absorbs the heat from the air and converts it from a gas into a liquid.

The refrigerant is sent outside where a fan blows hot air over the evaporator coils, which exhausts the air externally. The refrigerant is then cooled and converted from liquid to gas by the compressor and condenser. A fan located inside your home blows air over the coils to deliver cool air to your home and the cycle repeats.

Which refrigerants are banned?

R22 refrigerant is being phased out by the U.S. government by the end of the year 2020 due to environmental concerns. Suitable R22 replacements include R-407c and RS-44b.
