How much R-12 would you like? I have over 120 pounds on hand and can
buy more anytime I want. You DO have to get certified to buy it but that
takes about 20 minutes online and a weeks wait for your card. Current
pricing runs about 34.00 a pound. As for cleaning the system, disconnect
ALL fittings while you have it apart and flush them with alcohol, then
blow them out with clean, DRY air, I would replace the drier,
compressor, and orifice tube and ALL o-rings. Then pull a vacuum on it
and let it set with the vacuum in it as long as you can to make sure it
doesn't leak down. Then recharge it. You could do all the hard work as
far as the cleaning and repairs and then once the system is closed back
up take it to a shop to have them pull the vacuum and recharge it as
well.
