Having retired back to this area after over 30 years in a different part of the country, I consulted McCoy to establish ongoing residential service as needed. McCoy was (still) highly recommended by family and friends, as they had always been even before I moved away. I’m glad to confirm that their long-held family standards of expertise, fairness and honesty are intact. I’ve had them come out for at least a couple service calls on our “older” HVAC system, as well as for the recent replacement of our water heater.

Reviews
I was very impressed with McCoy Furnace Service. I expected to be told that my older furnace needed replacement, but instead received a thorough inspection and tune-up at a reasonable cost. The technicians arrived on time and clearly explained their findings. They replaced a faulty capacitor that resolved a slow-starting blower motor, cleaned the AC drainage lines, and showed me a video inspection of the heat exchanger, which was in excellent condition.
McCoy fixed a long-standing heating problem in our home. They were friendly, efficient, and affordable. Brett is very knowledgeable about the historic homes (and heating systems) in our area and gave us some great ideas as well. We’ll be using their services form now on.
