This was my first time using McCullough Heating and Air Conditioning. It was very easy to call and make an appointment over the phone. The technician, Mitchell, quickly diagnosed the problem and got it fixed and the heat working! He was very knowledgeable, and he didn’t mind me looking over his shoulder and asking questions as he worked. -I am happy with this service call visit; it was a good experience. I will call McCullough next time!
