The air conditioning industry is getting a breath of fresh air as federal regulations phase out ozone-depleting units from homes and commercial buildings.
The U.S. Environmental Protection Agency is slowly doing away with air conditioners that spout hydrocarbons, which deplete the ozone layer.
A new generation of more environmentally friendly AC units will be powered by gases such as R-410A, a mixture of difluoromethane and pentafluoroethane - which don't damage the ozone as severely.
Ronald Pento, president of RP Cooling Corp., a Hicksville commercial air conditioning contractor, said the shift will require not only a new substance, but new units.
