Project teams often confuse CFCs, HCFCs, and HFCs.Chlorofluorocarbons (CFCs) have been completely phased out of new equipment in the U.S. Hydrochlorofluorocarbons (HCFCs), the transitional substitutes for CFCs, are in the process of being phased out.

Project teams often confuse CFCs, HCFCs, and HFCs.

• Chlorofluorocarbons (CFCs) have been completely phased out of new equipment in the U.S. 
• Hydrochlorofluorocarbons (HCFCs), the transitional substitutes for CFCs, are in the process of being phased out.
• Hydrofluorocarbons (HFCs) are another class of refrigerants that are used as substitutes for CFCs and HCFCs. Currently, there are no federal regulations to phase out the production of HFCs.
• This prerequisite addresses only CFC use in base building equipment.
• EAc5: Enhanced Refrigerant Management deals with all refrigerants, including CFCs, HCFCs, and HFCs.
