The guy who does my ac makes a hell of a lot more money than me. I don't think it would be in his best Interest to put his life and family at risk to rob someone's 4 lighter . And being a combat veteran. I'm assuming you can aim. You are thinking crazy. If you live in SoCal I can give you a list of worthy people.. Most come precharged... You need the hvac guy to vaccum the lines.. To hook it up and vaccum the lines, they will normally charge you about 300 bucks... So it is close to getting robbed.. Takes them less than an hour to make 3bills. I'm sorry you had to fight for the wrong team and it's made you paranoid. Good luck
