We used Complete Comfort Heating and Cooling to have a new furnace and air conditioning system installed, and I was happy with their work. Before I reached out to them I had another company come out and I wasn't too happy with them. I didn't know what to do, and that's when a friend of mine recommended Complete Comfort. After they left I looked things over and thought, they were thorough, cleaned up after they were done, and I was very happy.
