What is Puron
Puron is Carrier's brand name for a refrigerant approved by the U.S. EPA to replace Freon-22, the most commonly used refrigerant in home heating and cooling systems today.  The government is phasing out Freon-22 because it contains chlorine, which harms the earth's protective ozone layer.

Why is the heating and cooling industry converting to Puron refrigerant?
Puron is the preferred alternative because it is environmentally sound, which means it doesn't deplete the ozone layer and it has low global warming potential.  It also has better performance than Freon-22.  Plus, the availability of Puron is not restricted, as it is for Freon-22.

How can consumers benefit from Puron refrigerant systems?
