All Freon is not banned. The old Freon 12 used in autos for many years is now restricted to licensed persons only. Autos today use the 134a refrigerant. IF you are changing your system from 12 to 134a you not only must pump the system down, but you must also change rubber hoses as those older ones will degrade with the 134a. As for window AC's the proper Freon used in most is Freon 22. Other Freon's used in dehumidfiers and some old refrigerators are Freon 17, and 19. Freon 22 can still be purchased by individuals.
I don't beleive there is a DIY kit for recharging window air conditioners. At least not one, that would be reasonably affordable (less than $100.00) . Now, if you have a friend who's in the auto repair business and as part of his work, he recharges automobile AC compressors, he may can help you. As he would have the knowledge to balance the high and low sides of the compressor. As well as evacuate and capture any freon that's left in the system. As freon has be banded by the EPA. R134a is now the refrigerant used in AC compressors. By now, I guess you figured out, that recharging the system is not necessarily a DIY project. It's best left to the pros.
Hope this was of hep to you and thanks for choosing fixture.
