D & M Heating & Air Conditioning was recommended to me by a friend, and I called them when my furnace wasn't working. They fixed it on the spot, but it turned out it would be cheaper to get a new furnace than do repairs.

They did a temporary fix, and then they came back out and put a new furnace in. They were on time, and they did a great job. They were very professional, and they informed me on how to use the new furnace. I thought it was a very good experience!
