We have always been happy with Complete Comfort Heating and Cooling, and always recommend them to others. They are very busy, so there are times they can't get out to us right away, although thankfully we've never had to use them in an emergency situation. But, when they're here they are very polite, and they know what they're doing. Their techs are always very knowledgeable about the problems we have had, and we will certainly use them again.
