R-410A is a new type of refrigerant created to replace traditional Freon refrigerant, dubbed R-22. This new refrigerant is chlorine-free and meets many of the newer environmental guidelines.
Because there’s no chlorine in it, R-410A doesn’t cause the same damage to the ozone layer that older refrigerants do. For this reason and because it’s generally more efficient, many manufacturers have made the switch away from R-22 to the newer R-410A refrigerant.
Manufacturers are beginning to consider phasing out R-410A refrigerant for the newer R-32 version, which has a much lower expected impact on global warming. Homeowners making a new purchase today can still buy systems that use R-410A. Unlike with R-22 there is no ban on production or import of R-410A refrigerant, and the R-22 ban does not affect homeowners who already own a R-22 system.
R22 is a chemical cooling compound used in older air conditioners and heat pumps. It is currently being phased out of production and use due to its harmful impact on the ozone layer when released into the air.
Refrigerant is a chemical cooling compound that absorbs and releases heat at different points in the heat exchange cycle as it runs throughout an HVAC system.
