I recently used TR Miller for the first time to snake my kitchen drain which was clogged. Adam was very friendly and knowledgeable. He got right to work and did a very thorough job. He cleaned up everything, leaving it looking better than when he came. I thought it was well worth the money. read more

Reliable staff, rendered a quality service and company that can be trusted to do a good job.

My sink would not drain at all. I called TR Miller and they were here first thing the next morning. Cristian L was very friendly, knowledgeable, and clearly explained each option and outcome before even writing up the estimate. He took time to make sure everything was successful. He explained the warranty, assured me everything looked good, and even dealt with my big moose of a dog so I didn't have to lock him up. If I ever need service again, I'd gladly welcome Cristian back into my home. My sink would not drain at all. I called TR Miller and they were here first thing the next morning.

They would not tell me how much they charge for a pound of R-410 refrigerant. I have to have them come out and pay them $79 to find out. If you have to hide your pricing until the tech is in your house, likely you are overcharging people. I will probably pay more for this service by going with Anytime Heating & AC, but at least I know the cost up front! read more

Chris from TR Miller Plumbing was beyond exceptional...he left my home about twenty minutes ago and I needed to write a review before continuing on about my day. His knowledge of hot water heaters was no less than what you'd expect an astronaut to know about their spaceship. But what impressed me even more was his ability to explain everything. He didn't just tell me what was wrong--he took the time to understand my hester's situation, explain how my current unit fit into my home, what a repair would actually accomplish, and how that compared to replacing it. I walked away anctually understanding my options instead of just being handed a bill. Beyond that, he was just a genuinely good person to have in the house. He was great with my kids, instantly won over my cat (and even shared photos of his own (hey Dempsey)), and made what could have been a stressful service call feel easy. When you invite a stranger into your home, their energy trulymatters. Competence matters of course, but character matters too. Chris could not have been a more shining representation of this company's character. If you're on the fence about who to call, stop looking. read more

Always kept informed, when arriving and who be working by sending a picture of agent. Brian was excellent, explained everything and very understanding. Belong to VIP program for several years. Now it was furnace and summer will be air conditioner. They did some plumbing in the past. read more

I contacted TR Miller late in the afternoon to have them come an unclog a drain. They stated they would be out the next morning, which was acceptable with us, and they would contact us before the technicians were to arrive. They did contact us and they did arrive at the time stated. We found a coupon for the work and presented it to a technician and he honored it with no issues. They used drop clothes to protect the house from dirt when bringing in/out equipment. The work was done as described. The technicians professional and pleasant. If we have issue in the future we will contact them. read more

TR Miller responded same day for my leaky kitchen faucet. Ryan was friendly and explained what he found and options to resolve it. Their service rate was fair and reasonable. Would definitely recommend them. read more

Marvin came out and did a wonderful job and explained what was wrong with my AC unit, diagnosed it accurately, and fixed it on the spot. The issue was minor, but for any issues going forward, he will be my first call! read more

We really trust TR Miller with every aspect. They have helped us with a few different kinds of projects on our house and have been quick, reasonable, and reliable every time. With big house projects like we have had, it is good to know we can rely on them! Thanks to Jim for the electric help today. Their work seems to be lasting and worth the investment! read more

Our service guy was friendly, knowledgeable, and very helpful! I'm glad that I called TR Miller!!! read more

Charged me $3,145 back in '23 For a water heater, there is now a problem which they want me to pay $356 to fix which I was told by a manufacturer and two other plumbers that this was an install problem. Just search TR MILLER COMPLAINTS in AI And you will get the real picture and the real info about what they do. There is so much more to the story but I'm going to just direct you to the above. I will never have them in my house again. read more

What an absolute joke of a company! Our water heater went out. Called T R Miller and they sent someone out. Milked me for a hour & a half. Told me that the whole water heater would have to be replaced. I'm not that mechanical, but I knew that wasn't the problem. Called another company & they ordered a part & fixed it in half an hour. T R Miller is NOT to be called for any reason!!! read more

Josh was knowledgeable and helpful at addressing our gas leak issue. We have used TR Miller previously for purchasing our furnace, AC, & humidifier. We have been happy with the service read more

Dustin P was absolutely fantastic!! He helped turn around a very stressful situation. He quickly and efficiently communicated the issue while providing clear quotes. Highly recommend!! 10 out of 10 read more

Words cannot express or emotions. The experience I've had with this company. This one day was extraordinary. Don C. Came out checked our water heater tested it, and it fired right up. Also, thank you, Dave for routing our service man out here. This was my mother's first experience with this company. And it's been absolutely terrific. Thank you Mark read more

I wanted to take a moment to thank Andrew S. for his exemplary service. He is a very knowledgeable and thorough technician who explained his findings clearly and concisely, giving my family complete confidence that our concerns were being properly addressed and that we had chosen the right company. We will be sharing this experience with family and friends. Andrew is a true asset to your team, and his outstanding work deserves recognition. read more

Tom & Jane Gallagher - Can't thank TR Miller enough for the prompt response when we called last Sunday about our faulty air conditioners. The estimator, Mike, came out first thing Monday morning!! Mike was very thorough and super knowledgeable - did a great job walking us through the estimate. This morning (Tuesday) the installer crew, Carlos, Joige, Arden, and Andrew, got right to work replacing both the upstairs and downstairs AC units (inside & out). They did an outstanding job on a big job!! The units are working great and look great! read more

I'd leave zero stars if I could. Over-priced - only care about emergency jobs that they can overcharge customers on. Will cancel pre-exiting appointments that were scheduled a month out. Does not matter if you were paying for VIP or not. They do not care about customers, only their next job they can rape and pillage on. ZERO INTEGRITY! Zero customer service. DO NOT USE! read more

I had a small leak coming from an ice maker line. TR Miller came out and fixed the problem very quickly. I had to do everything remotely and other than opening the front door, they were able to accommodate me and explained everything over the phone. I have used them for the past five years for everything HVAC and plumbing related and they are pretty good. A little pricey, but they come out when you need them, and the quality is usually pretty high. The service guys are always very polite and well spoken. If you want quality service and you want it fast, call these guys. read more

We had a new AC and furnace installed this past May.TR miller came out for our first inspection under warranty. appreciated the text advising me of the arrival time. The inspection was great and the technician provided info regarding upgrades and status of our 9 year old 2nd AC. very courteous and knowledgeable technician. read more

Lost cooling in the a/c. Called and was able to have Andrew S come out same day as our call. He was wonderful. He checked everything inside and out and was able to replace a part and had us up and working in no time. Andrew was friendly, knowledgeable and thorough. So so happy with the service and the response time. We were cooled off a couple of hours after Andrew S left. A 10+ starts experience. Thank you read more

8/6/2026 I wasn't sure if I wanted to leave a review, but I think it's a good idea that I do. Seeking Kinetico products I scheduled an estimate for 10am. I called at 10:12am to see if the tech was on the way and I was told yes. Then I got busy cleaning. Waiting to hear a doorbell ring, but realizing it hadn't, I went to my phone and found a text saying that my appointment had been canceled because I didn't respond to the text they sent asking me to confirm the day's appointment. This text was sent AFTER I called at 10:12am. The text went on to say that maybe there'd be time in the afternoon or some other day. I called the company and I said, yo, please. I'm here today at this house.Can you get somebody over here. They did, but they royally messed up the rest of my day. Domino effect on my calendar. It cost me $. The company also quoted me over $750 to remove a single bowl laundry room sink. Today I had a plumber on site and this is what I spent: LAUNDRY ROOM Sink disconnected New shut off valves SPIGGOT WATER LINES 2 shut off valves installed in the basemen to shut off the 2 spiggots and spent... $362.28 I now have serious concerns about inflated costs on my estimates for the water softener and RO system. I also realize I have to babysit my phone while I'm engaged in deep cleaning floors so I don't miss a confirming text otherwise my appointment will be canceled. The single star I chose shines very brightly for the tech that eventually showed up. He was professional and a great communicator. I won't be contacting this company for business especially not since i've read more of the reviews. read more

My HVAC guy was on vacation and our AC went out. He recommended TR Miller and they were able to get to us the next day. Turns out our blower motor was dead. They charged me $1800 to replace it, after trying to upsell me on a new furnace or a new wheel for the blower and a service plan. We went with just the motor and I had our guy come out to see if we really needed a new furnace or wheel. The blower motor that was installed typically costs about $250 so the labor was $1550. When I asked the technician why the high cost as our guy said it should be less than $1000 his response that TR Miller is a big business and can't offer prices that smaller companies can. Needless to say I feel taken advantage of and would not recommend TRMiller. The two stars is only because they got to us the next day. read more

Andrew S. came out to finish up a warranty job today. He ended up recommending some maintenance work to boost performance of our AC unit. I appreciated that he showed me the "before" and "after" readings so I could see that the maintenance had the intended effect. I also appreciated that he took the time to review our file before he headed out to our home. The last tech here recommended service on our boiler, which Andrew knew he wasn't qualified to handle, so the office called back to verify that they weren't supposed to have it on today's ticket. As with all of the TR Miller techs who have been to our house over the years, Andrew S. was personable, helpful, and efficient - and definitely delivered the excellent customer service this company is known for. read more

They installed our furnace/AC 20 something years ago, when they were named Tamarack, there service and pricing was second to none. They still had the same phone number when I called recently to get an estimate on new HVAC.. I was dissapointed at first, when they told me they are TR MILLER now. But the man that answered the phone was the previous owner. He explained he retired, but his sons took the business over. He remembered me and my husband. So I had them come out, and they were fantastic. Pricing, install,and service was something you really don't see of anymore. When it was time for a 3 and 6 month check up, they called me. Which indicates they are very service oriented. With all the choices out there today, it can really get confusing, but rest assured TR Miller is a company you can really trust. Sorry for the long review, but they truly are a remarkable company. read more

I am so proud and happy for this great company. TR Miller responded to my call and said they could be here today. first of all, after the horrible weather I was so happy to hear they could help me with my sump pump. Drew V. was so helpful and fixed my battery backup. He then showed me how to take care of it if it happened again. Thank you, Drew V., and thank you TR Miller Heating, Cooling, Plumbing and Electrical. I am truly happy. read more

Do NOT use TR Miller Heating & Air. I bought a new heating & air conditioner & hot water tank from them in June, 2025. I have had not heat on several occasions since putting in the new unit and called them out, the last being on New Year's Eve, 2025. They say 24/7 service but that is only for an answering service! No one comes out if after hours! read more

I had my AC/heater unit installed about a week before Labor Day this year (2026). I intentionally waited to write a review to make sure everything continued to perform well--and I'm happy to report that it has been excellent since day one. I'd like to thank Ryan, our salesman. He was professional, patient, and a pleasure to work with. He took the time to answer all of my wife's questions (sometimes more than once) and clearly explained how every component of our new system would work. He made us feel confident and at ease about such a significant purchase. I also want to thank the installation crew--John, Ammon, and Andrew. They were highly professional throughout the job. I was particular about how I wanted everything routed and finished so it would look clean and not be an eyesore. I checked in regularly and asked a number of questions, and they answered each one patiently and without complaint. When they finished, they thoroughly cleaned up and removed all debris. A special thank-you goes to Dusty, the plumber. He came out to replace a corroded shut-off valve for the humidifier. While he was there, he noticed that the basement sink was leaking when the faucet was turned on--a problem that had been bothering me for over a year. He fixed it in under five minutes at no charge. Thank you, Dusty, for going above and beyond. I truly appreciate it. For all of these reasons, I highly recommend TR Miller for your heating and cooling needs. Shout-out once more to Ryan, John, Ammon, Andrew, and Dusty. Thank you, Jose Perez read more

I am very pleased with the service from TR Miller. They had a coupon special for a furnace tune up for $59, which I thought was very reasonable. They scheduled me within days and were very good about keeping me updated on when the technician would be arriving at my house, along with his picture. The technician was very knowledgeable and explained everything that he was checking. Would highly recommend. read more

we recently had TR Miller out to replace our air conditioner and our heater. The crew that they had were amazing. They were so polite and respectful and did an amazing job. They left the area spotless. I would recommend them to anybody. read more

Major rip off. The $79 service fee covers nothing except to get them to your property. Then they give a dog and pony, cause they are not interested in your problem, they are there to bs you. "We're gonna do this, then we're gonna do this and that and blah, blah, blah". All I needed was an answer to a 2 wire question. "Oh, we'll get to that" but first we have to do a bunch of things you do not want or request. $350 later, I naturally object, so that's when the strong arm tactics begin. "We did all this work, we have it working, or do we?" "If you won't pay, we will take it apart and leave it the way it was when we got here". DO NOT LET JOCKI INTO YOUR HOME. He is a snake. Just enough of a mumbling accent to lead to confusion. So I'm burned out of $350, then they have the nerve to pitch their maintenance program. Ha! "Oh we want to make your home safe and check all you systems". "We want a "relationship with our customers". So pay us every month so we can come a find a bunch of this we can rip you off on. What a joke. They are not the only ones pulling this garbage. Simple, show up, answer the 2 wire question, take your$80 bucks and gtfo. STAY AWAY. read more

I recently had my furnace and air conditioner replaced by TR Miller. The sales rep was extremely helpful when I was making my decision. They installed it 2 days later. The team they sent (3 young men) was exceptional. They were polite. They took the time to explain everything they would be doing and they did an excellent job with the clean up. Their work was outstanding. After everything was installed they took time with me to explain how to work the new system. They answered all my questions. I highly recommend TR Miller if you are in need of HAVAC repair or replacement read more

They came and did an inspection on my HVAC and were very thorough. I am pleased with their service.

Great job installing my ceiling fan. Friendly and professional. Jim C. who came to give an estimate and listened to my concerns; and technician Josue P. who did the installation, was neat, respectful and took the time to explain the process. So pleased with the quality of work. read more

Kaleb W arrived on time. He wore shoe booties whenever he was inside the house. Kaleb carefully explained the results of his tests and observations. After completing his work, he made sure all the doors were closed and the lights were turned off. Kaleb was very polite.
