HCFC (hydrochlorofluorocarbon) and HFC (hydrofluorocarbon) are both types of synthetic refrigerants used in various applications. However, they differ in terms of their chemical composition and environmental impact. HCFCs contain chlorine, which contributes to ozone depletion, although to a lesser extent than their predecessor, CFCs.

Hydrofluorocarbons (HFCs) are synthetic organic compounds that contain fluorine and hydrogen atoms, and are the most common type of organofluorine compounds. Most are gases at room temperature and pressure.

HCFCs reclaimed for use as a refrigerant and for have been used in a wide variety of applications, the manufacture of a fire suppression agent including refrigeration, air conditioning (AC), foam used in handheld extinguishers, wheeled blowing, solvents, aerosols, and fire suppression.

HCFCs, or Hydrochloroflourocarbons, are the close neighbor of CFCs. The main difference between the two types of refrigerant is that HCFCs contain one additional hydrogen atom compared to CFCs. Both CFCs and HCFCs were widely used in the twentieth century as refrigerants, propellants, and solvents.
