I highly recommend D&M heating and air conditioning. My furnace went out and they came right out to look at it . They let me know all my options. They were helpful from beginning to end. They are very passionate about their work and the people they help service. Thank you.

Absolutely wonderful experience with this company, I highly recommend them! I called with an urgent situation of intermittent heat during a cold weekend, and they came out promptly, immediately diagnosed my problem, and had my furnace fixed and running within the hour. They were very professional and courteous and price was very fair, I was extremely happy with the whole transaction I just can't say enough good things, if I could rate higher than five stars I would, Thanks again!!!! - Finch Family
