Mixed bag. I cannot complain about the quality of the work or friendliness. We bought a service contract and then had a new system installed. One year later we sold our home and the inspection came back with two items: missing insulation on a refrigerant line and missing insulation on top of our attic access door. Not a big deal but when Bill showed up he insisted that he had to charge us for one of the items. The door insulation was laying in the attic because they had never placed it back over the door and he did that for free. Charged us for the missing insulation around the line even though they are the ones who left it off. Gave me a song and dance about how he had to charge us if he verified the fix. Well, I was not born yesterday. Be very careful about their service contract, just an excuse to come back and charge you for something.
