I suppose it is easy to throw around name brand as descriptions for actual products i.e kleenex for tissue or Saran wrap for plastic wrap, but when asking for help on specific systems and components you should know some, well, specifics. "Freon" is a trademark of du Pont de Nemours & Company (DuPont). It was formulated in 1928 and was made famous for its non toxic attributes that made people feel safe having refrigerators in their homes. I think the confusion comes from the fact that FREON also had products for vehicle applications such as Air Conditioning. This product was labeled Freon-12 (Dichlorodifluoromethane). In the 80's environmentalists started realizing that the CFC's (chlorofluorocarbons) such as Freon-12 destroy the O-zone so they came out with alternative products that are not AS hazardous to the environment. By 1995 No automobiles sold in the U.S. contained any FREON products. The most common refrigerant used now is R-134a (1,1,1,2-Tetrafluoroethane) And is easily retrofitted in to pre-1995 systems. So if your car has a R-134a retrofitted R-12 system or rolled off the production line after June of 1994 you do not have FREON in your Air Conditioning. Now that you are informed you no longer have ignorance as an excuse. Please use this information to help stop annoying automotive cliche. If you think I sound arrogant, remember that you clicked on a topic of "pet peev"
