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.

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! -
When our AC unit went out the D. Miller guys were here as soon as they could get here and had it back up and running. We have always had such great service from them and we really appreciate … More their quick response and knowledge. I highly recommend D. Miller Mechanical.

Absolutely! Heats pumps systems are much more efficient than they used to be and are extremely efficient even in cold weather. You will still need a backup heat source for an air exchange heat pump system but most of the time you won’t need to use it.
A geothermal system harnesses the heat trapped underground to heat your house. By laying a series of pipes several feet below the surface of your yard, we can use the difference between the ground temperature and air temperature to keep your house warm in the winter and cool and you comfortable while saving you money!

A Trustworthy HVAC Company Built by a Family, Serving The People of Columbiana County Ohio
A great reputation
Proverbs 22:1 says "A good name is more desirable than great riches". That's so true and it's how we run our business here in Northeast Ohio.
In business since 1992
We've been working hard and keeping customers comfortable since before most people had internet. A lot has changed in the world since then and our family has grown up a lot but we still run our business the same way.
Quality equipment - Expert installers
We don't play the price game because that means selling inferior equipment. We work with equipment we know will last because we've seen it last. Brands like Bosch, Carrier, and Bryant.
