AC systems still use refrigerant. It's only Freon if it's manufactured by DuPont, who trademarked the name Freon for a line of CFC and HFC refrigerants which they manufacture. Other manufacturers make the same refrigerants - they cannot, however, call it Freon, since DuPont holds exclusive rights to the name.

There are various types of refrigerant used in various AC systems.
