Home Air Conditioners That Use R-134a

While used mostly in cars, only one home air conditioner has been made, as of November 2010, that uses R134a as a standard. As of 2010, new home air conditioners that are produced must use a refrigerant that does not deplete the ozone. While R134a is eco friendly, most new air conditioners produced in 2010 use the R410a because it is even more energy efficient and environmentally friendly.

R134a is a hydrofluorocarbon that does not cause environmental harm.

The WeatherMaker 134A

The WeatherMaker 134A by Carrier Corporation is the first and only residential air conditioner that uses R134a as a refrigerant as of November 2010. The WeatherMaker is made in part from recycled materials and claims to make "efficient use of energy and reduces noise," according to Carrier Corporation. The WeatherMaker offers similar installation and maintenance to average air conditioners but claims to be much more environmentally friendly because the refrigerant "does not contain ozone damaging chlorine atoms," according to Hometips.com. As of 2010, similar home air conditioning systems are being produced, with refrigerants that are even a step above R134a as far as green quality goes.
