City Heating and Air installed our first heat pump including duct work. I got 3 estimates and took them to a man I know who installed heat pumps on the side and asked him about what was being done and the price. City Heating and Air was the most inexpensive for basically the same services so he recommended them. It was a hard job for them because of the size of the house and the fact that we had to have a split unit with it and the duct work having to be placed in the attic. We eventually had to get another unit and didn't even consider using a different company. Any time we have to call for some kind of service, they act very quickly with arriving and getting the work done. I also recommend their preventive maintenance plan. Great job, City Heating and Air.
