T.H.
DO NOT go thru Minnegasco! Their guys don't know what they're doing, and you end up spending more than you need to. The guys that we've used is Dennis from Team Mechanical. Make sure you get Dennis. He knows what he's doing, he knows how to explain things and he's really gifted at what he does. His direct line is ###-###-####. He also won't sell you anything you don't need, which was a problem we had with Minnegasco. If you need it, he'll suggest it and explain in full detail and totally understandably why you might want to consider it, but he never forces the issue. At least that's not the impression we got.
