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.
HFC/HFO Blends
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.
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).

HCs
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).
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.
