Testimonials
Great company and technicians. Called in the morning and they had my AC running by the afternoon. Very Thankful.
Honesty, integrity, fair prices they always helped me.
I am a local contractor. I do not use anyone else, but Miller I refer all of my customers to them and they are all satisfied,, top-notch servers and top-notch people.

I have a short term rental property in Mountain Home that had guests in it staying over the weekend. The HVAC system was not keeping up with the heat and my guests let me know the indoor temperature was 60 degrees. The outside temperatures were unusually low in the teens. I was able to reach Miller after hours and they were on site in about 30 minutes. I had some of the settings in the thermostat set incorrectly so the auxiliary electric “bars” were not coming on. The service tech changed the settings and the temperature came up quickly. This saved a potentially difficult situation with my renter and worst case possibly my water pipes freezing. Thank you Miller!
Call these guys! Excellent service!
Everyone from Miller was professional and courteous. They did a very nice job replacing our heat pump as well as doing additional duct work. All the work was done in a timely manner. They also left our house picked up & clean when they were done each day. Would highly recommend them.
I have been using these guys from the time I moved down here 6 years ago and they are the nicest most honest and competent people I have found. Besides getting the job done without trying to over sell something or over charging you like some of the places around. I 100% think you should use them for all your HVAC needs.
We had a 28 year old furnace and AC. Miller serviced it last year, and Mr. Miller was very honest that it was still in fair working condition, given it’s age and use. I appreciated his honesty. So this year we decided to go ahead with a full upgrade. His team was professional, prompt and courteous, even though they had an issue with the fitting the furnace into the attic. They managed all during very hot weather. We certainly appreciate them and are very pleased. 5* absolutely Highly recommend.
Thank you so much for coming to our rescue this very HOT weekend!!!! You guys are the best
