San Diego, CA., USA. Wednesday, January 30, 2013._The EPA is reducing the amount of ozone depleting chemicals we use, which includes the elimination of the refrigerant R-22 in our air conditioners. Instead, homeowners get to buy new, environmentally friendly units that use R-410A refrigerant (which doesn't punch a hole in the ozone).  Mauzy Heating & Air Conditioning of El Cajon, CA install furnace and A/C combos that are most likely the newer R-410A models. Scott McClain (cq), the General Manager at Mauzy, checks on the progress of an installation at a home in Rancho Santa Fe.  The house is so big that it requires more than one unit.
