An important change just around the corner is the phase-out of R-22. As of January 2010 the refrigerant R-22 (what consumers call Freon®) will not be allowed to be used in the manufacturing of new equipment. R-22 has been used as the “standard” refrigerant for many years but has been found to be harmful to our planet by our government. All new air conditioners and heat pumps will be required to use “environmentally sound” refrigerant, such as Puron® (commonly known as R-410A).
R-22 is the most commonly used refrigerant in residential homes today. However, per the Montreal Protocol, caps have been established to eliminate the production of R-22. In 2004, there was a 35% reduction; in 2010 there will be a 65% reduction; in 2015 a 90% reduction; and finally in 2020 a 99.5 % reduction in the production of R-22. This means that during the time of these reductions with high demand, the price of each pound of refrigerant could potentially skyrocket.
If you are considering replacing your existing air conditioning equipment, most higher efficiency products have already made the switch to R-410A, the more “environmentally sound” refrigerant.
