I have been using City Heating and Air Co. for a few years now, and I am sure that I will continue to use them in the future. More recently, they installed a new heat pump in my home, and it was done as requested. The unit has been functioning well so far, and I'm pretty satisfied with how everything turned out. The person who installed it was very accommodating and thorough in explaining what the unit does and how it functions, and was very helpful. I continue to use City because of their dependability. They're professional, accommodating, and efficient and I highly recommend them.
