Refrigerant Gas and the Law

Freon is a refrigerant used for most home heating, ventilating, and air conditioning (HVAC) units in America. While only a brand name of DuPont, the name “freon” often represents all HCFC refrigerants. The makeup of freon includes hydrogen, carbon, fluorine, and chlorine, or HCFC (hydro chlorofluorocarbons).
