HFCs

About HFCs

HFC refers to the chemical composition of the refrigerant. HydroFluoroCarbon indicates that the refrigerant is comprised of Hydrogen, Fluorine, and Carbon. A blend that contains different HFCs is considered an HFC refrigerant.

HCFCs

About HCFCs

HCFC refers to the chemical composition of the refrigerant. HydroChloroFluoroCarbon indicates that the refrigerant is comprised of Hydrogen, Chlorine, Fluorine, and Carbon.  A blend that contains both an HCFC and HFC is considered an HCFC refrigerant.

CFCs

About CFCs

CFC refers to the chemical composition of the refrigerant. ChloroFluoroCarbon indicates that the refrigerant is comprised of Chlorine, Fluorine, and Carbon. A blend that contains a CFC and any other product is still considered a CFC refrigerant.

Hydrocarbons

About Hydrocarbons

Hydrocarbons are naturally occurring chemicals made only from hydrogen and carbon. A blend of hydrocarbon with any other type of refrigerant would be considered the other type of refrigerant (CFC, HCFC, HFC, or HFO).

HFOs

About HFOs

HFO refers to the chemical composition of the refrigerant. HydroFluoroOlefin indicates that the refrigerant is comprised of Hydrogen, Fluorine, Carbon, and that there is at least one unsaturated double bond between two carbons (olefin structure). A blend of an HFO with another type of refrigerant is typically combined with a slash (example: HFC/HFO).
