Freon vs. Refrigerant — What's the Difference?
By Fiza Rafique & Urooj Arif — Updated on April 16, 2024
Freon refers to a specific brand of refrigerants primarily used in air conditioning systems, while "refrigerant" is a general term for any substance used in cooling processes.

Key Differences
Freon is a brand name traditionally associated with chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), which were common in various cooling systems. Refrigerants, on the other hand, include a broader category of compounds such as CFCs, HCFCs, HFCs, and natural refrigerants used for heat exchange in systems like air conditioners and refrigerators.
Historically, Freon was widely used in air conditioning, refrigeration, and aerosol propellants until the discovery of its harmful impact on the ozone layer led to many of its substances being phased out under international agreements. Refrigerants now encompass a variety of other substances that do not harm the ozone layer, including the more environmentally friendly hydrofluorocarbons (HFCs) and natural options like ammonia or carbon dioxide.
The use of Freon is now heavily regulated and is being phased out in favor of alternatives that do not deplete the ozone layer or have significantly lower global warming potentials. Refrigerants as a general category are also being evaluated for their environmental impact, but include both harmful substances as well as more sustainable ones.
Freon, due to its historical usage and subsequent regulation, has become synonymous with the environmental impact of refrigerants, leading to increased awareness and regulation in the refrigerant industry. Modern refrigerants are developed to meet stricter environmental standards, which Freon products originally did not.
While Freon specifically refers to a subset of refrigerants produced by the Chemours Company (formerly part of DuPont), the term "refrigerant" is used universally in the HVAC (heating, ventilation, and air conditioning) industry to refer to any cooling medium, regardless of its chemical composition.

Freon
Freon ( FREE-on) is a registered trademark of The Chemours Company, which uses it for a number of halocarbon products. They are stable, nonflammable, low toxicity gases or liquids which have generally been used as refrigerants and as aerosol propellants.
Refrigerant
A refrigerant is a working fluid used in the refrigeration cycle of air conditioning systems and heat pumps where in most cases they undergo a repeated phase transition from a liquid to a gas and back again. Refrigerants are heavily regulated due to their toxicity, flammability and the contribution of CFC and HCFC refrigerants to ozone depletion and that of HFC refrigerants to climate change.
Freon
(organic compound) Any of several non-flammable refrigerants based on halogenated hydrocarbon including R-12, R-22, and R-23.
Refrigerant
Cooling or freezing; refrigerating.
Freon

Refrigerant
(Medicine) An agent used to reduce fever.
Refrigerant
A substance used in a heat cycle that undergoes a phase change between gas and liquid to allow the cooling, as in refrigerators, air conditioners, etc.
Refrigerant
