D&M heating and cooling, Dan Jackson and his team are awesome. My furnace was pulling hot air down from my attic when my AC was running. It's a brand new furnace and central air unit not even 2 years old. D&M did not install, but they did not hesitate to come look at the mistake from the other company. I called Monday and made an appt for Friday and John from D&M came out Friday and made a plan. John called early Saturday morning and came within half hour and fixed the issue. John was very pleasant and helpful. I highly recommend and will be calling D&M from now on for any and all issues I have going forward. Appreciate all of you at D&M. Thanks a bunch from The Popovich family.

Highly recommend this company! Tony came out to service our air conditioner when it started acting up. He was incredibly thorough, taking pictures of the debris on the condenser coil to show us the root of the problem. He explained the entire breakdown clearly so we always knew what was going on. His service was so exceptional and friendly that we almost wanted him to stay for dinner. It is rare to find such an honest, reliable, affordable, family-run business.
