Changes ahead for valley air conditioning units
If you are getting ready to replace your old AC unit, you now have a new consideration to make; the type of refrigerant. Most AC systems in Arizona run off of Freon, also known as R22. Systems are now being offered that run on R 410 or Puron. Here is more information on why this change could be important to you.
From Wikipedia:"Freon is DuPont's trade name for its odorless, colorless, nonflammable, and noncorrosive chlorofluorocarbon and hydrochlorofluorocarbon refrigerants, which are used in air conditioning and refrigeration systems."In 2004, the Clean Air Act called for a 25 percent reduction in the supply of HCFCs. Like any other item, as supply is reduced, the costs for that item increases. In the year 2010, no new equipment may be manufactured that use R-22 refrigerant, which suggests that HCFC refrigerant is obsolete. Additionally, as HCFCs are further reduced, R-22 refrigerant may increase in cost. Additionally, as HCFCs are further reduced, R-22 refigerant may increase in cost as did R-12.Future Cost Of Service Savings - Because of U.S. government restrictions on future production, refrigerants with ozone-harming CFCs, the refrigerant used in most of today's heat pumps and air conditioners, will become harder to find and, eventually, more ... more
