"Very happy with these guys. Previously used one of their competitors (huge company; they sell a pricey maintenance plan and charged a lot for everything). Have used Kettering twice now. They’ve never tried to sell me any membership or maintenance plans.
Charges seem much more reasonable than the other guys (under $300 both visits; other guys charged me $300 to swap out a thermostat that I later found I could get from Home Depot for $50–they charged $200 just for the part and $100 to switch it out, which took 15 min). Kettering’s workers came when they said they would and seemed knowledgeable and polite. "
