I was complaining to a co-worker that I got an outrageous estimate for replacing my old furnace and she recommended One Hour Heating and Air. I called and quickly got a man to come give me an estimate that was perfect. He even saved me money by telling me I did not need to replace my ductwork. Two weeks later, they arrived exactly on time and 3 hours later I had my new furnace. They showed me how to work the new thermostat and how to clean the filters. They left with all trash and the old furnace. Excellent work!
