Dwight Miller (DMiller Mechanical) came to our house to give us a quote on replacing our 20 year old geothermal furnace that we’ve been pouring money into for repairs and also to replace our 20 year old hot water tank. He was 1 of 3 contractors invited to price his services He did a detailed examination of our current systems and explained our options in an logical, no pressure manner. He also provided a firm quote in writing for the cost to do the job. We thanked him for his time while we waited on the other 2 contractors to give us their quotes over the next few days Price is not always the final factor when spending the hard earned money we were about to spend One contractor was less expensive and one was way more expensive. Dwight’s quote was somewhere in the middle We chose Dwight and his team for a variety of reasons: He could do the job very quickly verses waiting 6-8 weeks He was local. You want someone that can meet your needs if problems arise. His is a family owned business. His income and livelihood depends on his reputation (high marks on HomeAdvisor) The personal connection we felt in our spirit with Dwight. He is a like minded, kind hearted Christian business man It turns out that Dwight was the correct person to deal with. Dwight and his adult sons(experienced professionals themselves) showed up each day when they said they would They went out of their way to protect the interior of our home during the tear out of my old systems and the installation of the new units This was a large, labor intensive, skilled job. They took the upmost care to make sure the installation was perfect. Duct work was hand crafted to attach to my existing ducts After the multi-day job was completed they hauled away the old units. They throughly cleaned up the work area. You couldn’t even tell someone had just worked there when they had finished Dwight then took the time to fully explain to my wife and I how the controls worked so that we understood them. This long winded review is for the purpose of stating: If you want an honest, hard working Christian family business that is very professional and makes sure you are happy with the results, then DMiller Mechanical is the company you SHOULD hire to do your heating and cooling work. He is the real deal and I highly recommend that you hire him with NO reservations You won’t regret it

Very responsive, professional and honest. Many contractors would have shown up (eventually) taken one look at my 25 year old A/C unit and just condemn it. D. Miller arrived as promised, took just a few minutes to diagnose and quote the job. A/C running again just in time for a dozen dinner guests. Thank you, I’m glad we could do business.
