come on guys, the guys without licenses make the real techs look good. How many times have you ever gotten a call and the unit is all hacked up. You go and tell the customer whats going on and then fix it. Iv'e deal with alot of customers that had something hacked by an unlicensed contractor and now they call us. Most of those customers are the ones that never question a bid or service charge anymore, they've learn't they get what they pay for.
