Gunthers Comfort Air redid my furnace. They took out the old one and put in a new one. I think that their expertise is refreshing; they are one of the few companies that actually knows a lot about HVAC systems. They seem like HVAC engineers, not just furnace installation people. They spent a lot of time looking at the whole system, they explained what was going on, and they answered any questions I might have had. I had never used them before but I would definitely go back again.
