R-410A, an environmentally friendly refrigerant used in air conditioning systems, does
not contribute to ozone depletion and is becoming more widely used, as ozone-
depleting refrigerants, like R-22, are phased out. Every major air conditioner
manufacturer in the United States has selected R-410A to replace R-22 in new
equipment. R-22 is being phased out, and the manufacturing plants that make R-22
will eventually be shut down or converted to make other chemicals. In 2003 the U.S.
make and import R-22, and the amounts that they each can make or import. The
Clean Air Act requires that as of 2010, all new air conditioning and heat pump units
manufactured in North America will use chlorine-free refrigerants. So by choosing an
R-410A air conditioner or heat pump, you’re getting the latest in refrigerant
technology and helping the environment!
Our technicians are certified in R-410A refrigerant by Mainstream Engineering.
