"I replaced both of my forced-air furnaces and a/c units due to age (25 years) and efficiency. I also replaced two humidifiers and upgraded to wi-fi thermostats. I contacted TR Miller and another American Standard contractor to receive bids. Tim (the owner) came out and did a thorough job of accessing our situation and walking through his proposal. I contacted both contractors over the next 7-10 days to better understand competing proposals as well as negotiate the overall price. While both parties were close on price, Tim's level of responsiveness and demonstrating that he wanted the business made the difference.
We scheduled an install date for Nov 8th. His crew of five installers showed up on schedule (8am) and worked diligently through the day. They were all very professional and always willing to explain what they were doing if I had questions. Amazingly, the job took just under the 8 hours they estimated. Ben, the manager, provided a detailed walk through of all the work, how to care for the units, as well as things to watch for. Another installer explained how the wi-fi thermostats worked (which are awesome and highly recommended by the way). There was quite the mess from ripping out my old units and some of the duct work, however the crew cleaned up everything. After they left, it was as if they were never there.
Overall, I could not be happier with the process. Despite rather mediocre reviews on Angie's List, I can't say enough good things about my experience with TR Miller.

"He is very patient in fixing my furnace. There were multiple fix he did and now my furnace is working as I wanted it. Other HVAC contractors were unable to fix, but he was able to get the job done."

"I needed the refrigerant in my HVAC system refilled and Juliano and Richard were quick to respond and very professional. They inspected the system and completed the job in one day. Very satisfied with work performed."

"AWE promptly responded to my work request and kept me informed about my appointment status. Peter came to perform the work. He was very thorough and even discovered that the HVAC contractor on our new home installed 2 furnaces: a current year model as well as a prior year model that was more prone to breakdowns. Provided great information and would definitely hire again. Thanks!"
