Do air conditioners still use Freon?
Most of the air conditioner systems installed since 1970 have used a refrigerant labeled R-22, commonly called Freon, which is a trade mark of the DuPont Corporation. The manufacture of equipment and products using refrigerant R-22 will cease by the year 2010. R-22 refrigerant production will end in the year 2020. Supplies of R-22 will become scarce and it’s cost will continue to rise. Alternate refrigerants have been introduced such as R-410A in 1997, and R134A.
