I've had D & M Heating & Air for over 20 years and I've liked them ever since the first visit. I first used them to have a furnace put in, and they came recommended to me by my brother-in-law. I now have a maintenance plan for them to come and check the air conditioner and furnace in the spring and fall. They always call me to setup the appointment, and they call the morning of to say that they are coming within the hour. I like that a lot, because then I don't have to sit and wait for them to show up, which is pretty good. I am very satisfied with them, and I have recommended them many times.
