Now that's helpful right there...don't care who you are...
Except that it is incorrect! Freon, a Dupont trade-name, is still used by Dupont for their R13 replacement refrigerant. The name Freon has not been phased out.
R22 refrigerant is in the process of being phased out. Where I work, we have pallets and pallets of it and are still able to purchase it as long and the national inventory lasts.
Symantics, here because the word Freon has been a term missused by many over the years. It has been used to describe R12 which was phased out many years ago. It is currently being missused to designate the new R410A as well as many other refrigerants over the years when, again, it has always been a trade name used by Dupont.
R22, as well as other refrigerants, have different trade names depending on the manufacturer.
Commercial names
Freon is DuPont's brand name for CFCs, HCFCs and related compounds. Other commercial names from around the world are Algofrene, Arcton, Asahiflon, Daiflon, Eskimo, FCC, Flon, Flugene, Forane, Fridohna, Frigen, Frigedohn, Genetron, Isceon, Isotron, Kaiser, Kaltron, Khladon, Ledon, Racon, and Ucon.

As one who has been in the AC/REFRIGERATION BUSINESS FOR 30+ PLUS YEARS I would love to hear your version of the difference between "freon" and 12/22?? .....I have been under the impression all these years "freon was Dupont's branded name for their different refrigerants..12. 22, 500, 502 etc...documentation please...

Chlorflouromethane in 30 lb. cylinder, branded Dupont. R-22 has a boiling point of -41 C. R-12 boiling point is -30 C..
Lately, if I encounter an appliance that has a fill port installed, I suggest the owner replace the appliance. It is more expensive to charge the system a couple of times than replacement.
