I have used Sears Heating & Cooling in the past, and I have always been happy with them. They are professional people, and nice people, too. They know what they are doing. The last time they came out, it was to make a repair to the heater. I was in the hospital at the time, and only part of the heater was working. They got that fixed for me. I have a maintenance contract with them, and this last year they were late coming out, so they combined the spring and fall service together. I hope that they do not do that again.
