Family Air is a really wonderful company, we've had them over a few times. The back of our house was so much cooler than the rest, so a gentleman came out to survey the situation. He suggested we remove our old thermostat in the hallway and put new on in the living room. It was a good suggestions so we had them do that. That really helped. The folks that came out were just delightful, and so far everything has been all good.
