    D Miller Mechanical came and cleaned my coil, optimized my blower, and installed larger return air ducts to make my system more efficient.
    They also recommended installing an entire house
    … More humidifier system. This was a game changer! I highly recommend them if you would like to work with a company that is punctual, honest, and knows their stuff!

    Dwight and his team have bailed us out more than once. First, he was the most responsive in an emergency call, and did amazing work for us. Then he later replaced the whole heating and … More cooling system, plus installed a wireless smart thermostat, and did amazing work. He communicates well, overdelivers, is prompt, does great quality work, really cares about the ultimate outcomes, and is just a pleasure to work with. We will keep using him for all our needs.
