Twas the Saturday after Christmas and all through the house, the heat was not. In a panic, we called D&M and 20 minutes later a technician was at our home. He was fast efficient and had us up and running quickly! Genuinely appreciate good customer service. Definitely recommend to anyone with heating or cooling needs. Y'all have a customer for life. Thank You!

I woke up on Christmas Eve to no heat! After returning home, I called and within just a few minutes Dan called me back and was able to talk me through resetting my furnace over the phone! My heat started working again within just a few minutes. He was in my area yesterday looking at someone else’s furnace and decided to stop by and follow up to do a quick diagnostic check! I absolutely will be a returning customer and will refer this company to everyone! Thanks again D&M!!🙌
