Can You Use R-134 in a House's Air Conditioner?

The Earth's ozone layer is a shield some 35 miles above the ground that protects us from the sun's harmful ultraviolet rays. In the mid 1980s it was discovered that air conditioner refrigerant was damaging the ozone layer. The refrigerants used at that time were known as chlorofluorocarbons (CFCs) and hydrochloroflurocarbons (HCFCs). This led to the signing of the Montreal Protocol of 1987, in which 180 countries agreed to phase out CFC production by 1995 and HCFCs by 2030.

R-134a refrigerant is a member of the HFC family of refrigerants. HFC refrigerants are widely used to replace CFC and HCFC refrigerants. R-134a is non-toxic, non-corrosive and non-flammable. It's currently being used in newer automobile air conditioner systems. It's used as a propellant in the pharmaceutical industry, and in manufacturing, where it's used in plastic foam blowing.

HFC refrigerants such as R-134a and R-124 lack a chlorine atom and are not destructive to the ozone layer. They do, however, have a slight impact on global warming. They're safer for the ozone layer than CFC refrigerants, which were developed more than 70 years ago and ceased production in 1995. HFC refrigerants are still used today in residential air conditioners. Much of this equipment can last up to 30 years.

As a consumer, you can do your part to help stop ozone depletion by purchasing air conditioning equipment that uses R-134a and the newer refrigerant blends. She just cut her electricity bill to 60%, click here to read. Most units will be labeled "ozone friendly" and state the type of refrigerant used on the label. Avoid buying older equipment that uses CFC and HCFC refrigerants.

In 2010, the production and import of HCFC-22 for newly manufactured equipment was banned. Production and import limits were set for its use in existing equipment. Between 2010 and 2020, both HCFC-22 and HCFC-142b will be limited to servicing existing equipment. In 2015, the sale and use of HCFC-22 will be banned except for transformation or servicing refrigerators and air conditioners. In 2020, the production of HCFC-22 will be completely banned in the U.S. This leaves HFCs and refrigerant blends as the only options available in the future.
