Stop in for a cup of coffee

Got the R12 all in and he saw the schraders were leaking. :wtf: :BangHead: Then he's like "if you get the valves I have the tool to change them" Huh, you can do that? Without taking the charge out? ...He goes and gets the tool and guess what? There's extra cores in the bag with it. Oh, didn't know I had them"... Swapped them out and the Duster AC is all charged and chillin'. :thumbsup:
