Had Dwight out to repair my 30+ year old AC unit. He was fast to respond to my service request and scheduled us for the next day. He replaced a failed capacitor and had the unit running … More within minutes. He's honest, professional and really a good guy. When the time comes for a new unit D.Miller Mechanical will be our first call.

Dwight's two sons came and removed our old heat pump and replaced it with a brand new Bosch brand heat pump. They were very friendly, knowledgeable and answered all my questions! Their … More work was excellent and when they left, here was not a single thing left, everything was clean and the workmanship was perfect. We were very pleased with it and it works so much better than the old one and is much more efficient. I highly recommend Dwight Miller for anything you have to have done of air conditioning and heating issues. Ted Steckley

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.

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!
