Replacing outdated HVAC equipment with modern, zero-use CFC HVAC equipment limits CFC damage to the ozone layer. Chlorofluorocarbons (CFC) have been proven to deplete the protective layer of stratospheric ozone, and the Montreal Protocol instituted a worldwide phase-out. In 1996, the U.S phased out production of CFC and products that use CFCs. However, equipment that dates to pre-1996 may still contain CFCs.
Equipment in the U.S that uses CFCs is outdated. Companies that install or replace old HVAC equipment with new HVAC equipment could realize large savings in efficiency and also prevents the release of CFCs into the atmosphere.
