CFC is Cloroflurocarbon and it refers to the Clourine, Flourine, and Carbon that are present in Freons such as R12. Most home AC units use R22, which is a HCFC, that is HyrdoClouroFlouroCarbon. Any Freon that starts with R requires a EPA license to purchase, and any that ends in A (such as 410A or 134A) is available to the public.
