Chris Young recently went back to work at his old day job. Before he was singing hits like 'Gettin' You Home' and 'You,' Young was in charge of cooling people off as an AC. repair man. Young installed air conditioning units and did the other duties required of an HVAC technician, but says he wouldn't want to trade his current gig for that kind of work again. It's too hot in the Nashville summer to be crawling around people's attics, as he found out on an episode of GAC-TV's 'Day Jobs.'
