As of January 1, 2010 HVAC system manufacturers no longer produce air conditioners and heat pumps containing R-22, commonly known as Freon. 

Consequently, the HVAC industry has shifted to the refrigerant R-410A, commonly known as Puron.  You can continue to get your current unit serviced and repair R-22 systems, but in the event that a heat pump or air conditioning unit needs to be replaced, you will want to:

  • Replace components that are necessary to maintain compatibility with the replacement unit
  • Replace the indoor furnace or air handler, evaporative coil, transition, plenum, indoor electrical, duct connection, accessible refrigerant and condensate drain lines and thermostatic expansion valve (TXV).

Eventually the R-22 inventories will be depleted and R-410A will be all that is available in the marketplace.
