Central Cooling & Heating has been servicing my heat pump heating and cooling system for 9 years. I have a service contract with them. They come twice a year, tune up and replace filters. They are always on time. Just like his colleagues, John left a clean place. Additionally, over the years I also had a few emergencies and each was resolved efficiently.

Reading other reviews I conclude: that CCH takes care of existing customers first before soliciting new ones. Comcast could learn something here.
