What is Freon/R-22?
Hydrochlorofluorocarbon (HCFC), known as R-22, has been used as a refrigerant for more than 40 years by HVAC manufacturers. While HCFC’s are considered safe for the environment they do contain chlorine which is classed as an ozone-depleting chemical. The Clean Air Act set a target date of January 1, 2010…
What does SEER mean?
Season Energy Efficiency Ratio. It is a system for rating the efficiency of air conditioning equipment. SEER is calculated by dividing the cooling capacity in BTU/H, of a continuously operating air conditioner, by the electric power input, or watts, of power consumed. The higher your SEER, the less the unit…
My ten-year old air conditioner was called high-efficiency and I was told that was why the outdoor unit was so large. A neighbor replaced his air conditioner and his outdoor unit is about half the size of mine. Why is this?
Generally, higher efficiency units are larger than standard units. This is due to the added coil area for heat transfer. In addition, some manufacturers make units that are physically larger than other manufacturers. Some of this is due to their desire to make the unit quieter as well as more…
How Does the Accelerated Phase-out of R-22 affect me?
The Environmental Protection Agency, (EPA), a part of the US government, recently proposed an accelerated phase-out of R-22 which is an HCFC (hydro-chlorofluoro-carbons) refrigerant known by various names such as Freon Genetron, Isotron, Carrene and Frezone. The Montreal Protocol, an international effort, has a goal to eliminate these recognized ozone…
