In the past, air conditioners used CFCs and HCFCs as refrigerants until the discovery of their impact on the ozone layer. The use of CFCs have been phased out since 1995, and HCFCs are being used as an interim solution which will be phased out by 2030. Currently, HFCs and refrigerant blends are being created to replace the others, though some HFCs do have a slight effect on global warming. If you have an older air conditioning system, it may still be using HCFCs but because ACs operate in a closed system, it should not be harmful unless there is a leak.
