 They'll go over and say, hey, is this unit salvageable? Can you still get a few years out of this thing? Or is it ultimately going to be cheaper to just get a new unit that's going to last you for years and years to come? Jerry bailed me out a couple of weeks ago on my air conditioner. I was a little worried about it, but he took me through some tips and pointers, and we got through it. It's the kind of service you can expect. Lemons, heating, and cooling.
