I picked these up at an estate sale. I am not an AC guy, so I don’t know much about them. I have been told freon doesn’t go bad, is there a way to test it? The tanks defiantly have pressure in them… You can have them both for $100.00 since I have no use for them. Call or text, John show contact info
