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

I have trusted TR Miller for a complete HVAC, water heater , sump pump and drain clearing over the last few years. After scheduling any service I received confirmation texts and updates that kept me fully informed including name and picture of the service person arriving. Every service person was very personable and professional. The quality and value of their services was outstanding. As a homeowner over 30 years I fully recommend TR Miller. read more

Very prompt and professional from the phone call to the office setting up an appointment to the tech arriving and diagnosing the problem with my air conditioner. Signed up for their TruCare program so they can take care of any other HVAC, plumbing or electrical needs I may have. 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

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

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

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

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

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

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

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

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

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

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

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

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

I've always been very happy with the staff at TR Miller. It's a secure feeling for a widow to know that help is only a phone call away. From the office staff to the service reps, they've always been kind, professional, and thorough. Julian was great today explaining all he was doing and very kind. Thank you. 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

Had maintenance for ac today and the tech Daniel was very professional and did a great job! That is always appreciated!

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

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

I have used TR Miller in the past and have been very happy with them. The techs have been wonderful and I recently had Daniel out for a one year check up call. He was very polite and professional. 5/5! 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. Because of this positive experience I decided to purchase a TR Miller VIP Service agreement to cover both our furnaces and air conditioners. read more

Josh was very knowledgeable and comes highly recommended. He is my go to when I need something done fast

Kevin the tech identified the issue and was able to enact a temporary fix until the part comes in to correct the issue. I've used TR Miller in the past and overall they deliver good service. read more

Today Andrew arrived to perform a service check. He was respectful, described things well and was thorough. My husband and I felt all our questions were thoughtfully addressed read more

Per usual, TR Miller sent Jacob W out soon after I called and assessed our plumbing situation with a few different options and recommendations which were well explained and documented. He got us scheduled for 2 days from the visit, and then addressed another plumbing question for me, with options and pricing...over and above!!! Thanks Jacob W! Dean A read more

They kept me informed of arrival. The technician was knowledgeable and friendly. Everything was explained

Alex showed up on time as scheduled for the appointment. I've used TR Miller before and I've always been impressed about their scheduling communication and on time service. Alex was dressed professionally and was obviously trained well while he was there. He fixed another small issue with our furnace that was unrelated to the AC repair and helped us out for essentially no charge. I run a service industry company and I'm always jealous of how well the in the technology that they use. It's very very difficult to get service consistency and it requires a tremendous amount of training time and investment. My only issue is today's AC units and furnaces tend to break at a higher rate than units in the past. It just doesn't seem like their usable lifetime is as much as it used to be. read more

The technician arrived on time. He explained everything that he was going to review and fix.He was very knowledgeable. My A/C has never worked better.Two sets of filters were changed and outdoor unit was inspected. Having the T R Miller monthly subscription is also a relief as there are benefits. Great staff who are very helpful. read more

Brandin A did a fantastic job. He was very knowledgable and nice! Would definitely recommend.

Our A/C went out on Thursday, 7/2. Called around 6pm to see what they could do. By 2:30-3pm on Friday, 7/3, Kaleb W was at our house, diagnosed and fixed the problem and was gone within 20 minutes! We LOVE TR Miller and recommend them to EVERYONE!!!!! read more

We couldn't be happier with the service we received from TR Miller. We had an air conditioner emergency leading into one of the hottest spells of the year and not only did they send a tech out the same day we called they were able to get someone out for a full estimate also that same day and do the install the very next business day. Everyone we worked with was extremely professional and courteous. This is the second time we've used them and we are lifelong customers. read more

I couldn't be more satisfied than we were with our plumber Chris. He is very knowledgeable and thorough with our inspection. He went over things to be aware of and fixed the issues that we had. I can say the same with TR Miller's H Vac inspections. We are satisfied customers. read more

We have had great experiences. Communication is excellent, response time is great. Their employee Ryan F. is highly skilled and will take the time to show you important aspects of maintaining your plumbing through your home. Found them honest and simply excellent! read more

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

TR Miller Heating, Cooling, Plumbing & Electrical - Heating & Air Conditioning/HVAC Near Me - Plainfield, Illinois

Jason was timely and professional. everything was done properly. I will use them again!

Very thorough, informative and helpful. AC stopped working over night and they came early in the morning and walked us through all the options and helped us make an informed decision read more

I've used TR Miller a few times. I was on the "VIP " program which has been a WASTE of 19 bucks a month, you don't get anything out of it! All the techs have been nice except when you don't want to have them do a job lol! I paid $788 because my water heater was making noise. Guess what it still does! Actually never stopped even after they "fixed" it! They sent another tech out and they'll fix it for another 300 bucks! I will NEVER use them again. I also have asked numerous times to stop charging me for the VIP program. I literally need to call them once again! Stay FAR away from this company. They create more problems to keep coming out and make more money! read more
