Phase-Out of R-22

Hydrochlorofluorocarbons (HCFCs) are chemicals used as refrigerants in the air conditioning and refrigeration industries. Scientists believe that the chlorine molecules in HCFCs can damage the ozone layer that protects the earth from harmful ultraviolet radiation.

In 1987, an international environmental agreement called the Montreal Protocol established a worldwide, structured phase-out of HCFCs. The most well-known HCFC is R-22, which has been the refrigerant of choice for residential heat pump and air conditioning systems for more than 40 years. Beginning January 1, 2010, the production and importation of R-22 was banned except when needed to service existing equipment.

New air conditioning systems contain a more environmentally-friendly family of refrigerants made of hydrofluorocarbons (HFCs) without the chlorine molecules. It is believed that HFCs do not contribute to the depletion of the ozone layer. The HFC now being used in most residential applications is R-410A.

All R-22 in existing air conditioning systems must be recovered and captured rather than being released into the atmosphere. Although R-22 equipment will no longer be sold and installed in the United States, existing equipment can continue to be used. If you presently own central air conditioning equipment containing R-22, there is no need to worry about replacing this equipment prematurely. The R-22 needed to service this equipment will be available indefinitely. However, over time, as supplies of R-22 become limited, the price will most likely increase.
