HCFC's
HCFCs are compounds containing carbon, hydrogen, chlorine and fluorine. Industry and the scientific community view certain chemicals within this class of compounds as acceptable temporary alternatives to chlorofluorocarbons. The HCFCs have shorter atmospheric lifetimes than CFCs and deliver less reactive chlorine to the stratosphere where the "ozone layer" is found. Consequently, it is expected that these chemicals will contribute much less to stratospheric ozone depletion than CFCs. Because they still contain chlorine and have the potential to destroy stratospheric ozone, they are viewed only as temporary replacements for the CFCs. Current international legislation has mandated production caps for HCFCs; production is prohibited after 2020 in developed countries and 2030 in developing countries.
HFC's
"Hydrofluorocarbons (HFCs) are compounds containing carbon, hydrogen, and fluorine. Certain chemicals within this class of compounds are viewed by industry and the scientific community as acceptable alternatives to chlorofluorocarbons and hydrochlorofluorocarbons on a long-term basis. Because the HFCs contain no chlorine they do not directly affect stratospheric ozone. Furthermore, mechanisms for ozone destruction involving fragments produced as HFCs are decomposed within the atmosphere (CF3 radicals) have been shown to be insignificant.
Like HCFCs, the HFCs contain hydrogen that is susceptible to attack by the hydroxyl radical. Oxidation of HFCs by the hydroxyl radical is believed to be the major destruction pathway for HFCs in the atmosphere. Atmospheric lifetimes of the most commonly used HFCs (HFC-134a and HFC-152a) are limited to <12 yrs because of this reaction.
Although it is believed HFCs will not deplete ozone within the stratosphere, this class of compounds has other adverse environmental effects (see the Chlorofluorocarbon Alternatives Measurement Project info)-for example, these gases are efficient absorbers of infrared radiation. Concern over these effects may make it necessary to regulate production and use of these compounds at some point in the future. Such restrictions have been proposed in the Kyoto Protocol." - The US Global Monitoring Lab

HFC-HFO's
HFC-HFO refrigerants are synergistic blends of Hydrofluorocarbons (HFCs) and Hydrofluoroolefins (HFOs) designed to balance environmental sustainability with operational safety. While traditional HFCs like R-410A are highly stable but possess high Global Warming Potential (GWP), newer HFOs offer ultra-low GWP but are often mildly flammable. By blending these two chemistries, manufacturers create "bridge" refrigerants—such as R-454B and R-448A—that significantly reduce carbon footprints while maintaining the performance and safety profiles required for modern HVAC and refrigeration systems. As of 2025, these blends have become the industry standard for complying with the Kigali Amendment and the EPA's phasedown of high-GWP substances.
Hydrocarbons
Hydrocarbon (HC) refrigerants are natural, organic cooling agents composed entirely of hydrogen and carbon. Unlike synthetic HFCs, they are "natural refrigerants" that occur in the environment, primarily as byproducts of natural gas and petroleum production. They are favored for their zero Ozone Depletion Potential (ODP) and nearly zero Global Warming Potential (GWP), making them one of the most climate-friendly options available. While they possess superior thermodynamic properties and often lead to higher energy efficiency than synthetic alternatives, they are classified as A3 (highly flammable). Consequently, their use is governed by strict safety standards regarding "charge limits"—the maximum amount of gas allowed in a single system—though these limits have been expanded as of 2025 to allow for broader use in commercial refrigeration and heat pumps.
Recovery Cylinders
Refrigerant recovery cylinders are specialized, DOT-approved refillable containers designed to safely store and transport refrigerant gases removed from HVAC systems during service, repair, or decommissioning. Unlike single-use "disposable" cylinders, which are strictly prohibited from being refilled, recovery cylinders are built from high-strength steel or aluminum to withstand the repeated stresses of pressurization and evacuation. They are easily identified by their signature yellow-and-grey color scheme (for non-flammable gases) and are equipped with dual-port valves that allow for both liquid and vapor extraction. As the industry shifts toward mildly flammable A2L refrigerants in 2025, modern recovery tanks often include additional safety markers, such as red bands, to indicate compatibility with these lower-GWP substances while ensuring compliance with EPA Section 608 environmental regulations.
