    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

    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.
