What You Need to Know About R-410A Refrigerant for Air Conditioning Systems

On January 1, 2010 the EPA began requiring R-410A (also known by the brand names Puron, SUVA and GENTRON AZ-20) refrigerant in air conditioning and heat pump systems. This means that all air conditioning and heat pump equipment produced in or imported to the U.S. must use R-410A or another non-ozone depleting refrigerant.

Why was this change made?

The release of HCFCs (hydrochlorofluorocarbons) into the atmosphere has depleted the earth's protective ozone layer, and created an ozone hole. This will help restrict the release of this manmade chemical and others that deplete this layer and help it to recover. This is a worldwide initiative.

How has HWA complied with the R-410A regulation?

  1. Air conditioners and heat pumps that use R-22 can still be serviced and repaired and R-22 will still be available for use in equipment that was manufactured prior to January 1, 2010.
  2. When a replacement system is necessary, a system can still be replaced with R-22 equipment as long as it is available. There is no ban on the sale of R-22 equipment, the new regulation only requires manufacturers to produce R-410 equipment.
  3. HWA will implement some upgrades and modifications needed to bring your covered heating/cooling system into compliance with crucial SEER and HSPF standards.

Note: The price of these phased out coolants and R-22 system parts will continue to rise as their availability decreases, and may take longer to acquire.
