HVAC reviews in Plainfield, Illinois

I elected to go with TR Miller with the expectation of highly competent professional performing the work I needed done, fair pricing and a company would stand behind its work. Robert and Christian just the completed the installation of a new water heater and with the addition of a hot water recirculation system. Good guys, excellent work. Overall I am very pleased and look forward to working with TRM in the future.

The team was very professional, friendly, and easy to work with. They installed a brand new HVAC system and did a great job from start to finish.
Shoutout to Derek H., Sergio, Carlos V., and Maleeyah B. for their hard work and attention to detail. Everything was explained clearly, the work area was kept clean, and the job was done right.
I’d definitely recommend TR Miller to anyone needing HVAC service

I was very impressed with Jon G and Javier V. They were at my residence early, very professional, friendly and very thorough with explaining the installation process and answering all my questions. Very much recommend this team and TR Miller!! New furnace and soon AC as well. Very pleased with the service and attention to their customers. Great job!

Bogdan T was amazing!! The service he provided for my mom when we had an issue with our furnace a week before Christmas. He was kind, polite, funny and truly a pleasure to work with. He found the problem and took his time to explain the issue we had to me and my mom, he also pointed out other things we should monitor and look out for in the new few months. His warmth, patience, and hospitality is a rare thing to experience in a society that has focused more on securing a sale than the overall customer experience amd service. You can do both, and Bogdan did. Bogdan was an excellent technician and someone we requested to be the only person we work with at TR Miller Heating, Cooking, and Plumbing in the future. If you want someone to come in, get out, push a sale, and hand you a bill. Then go to someone else. If you want to have someone explain what the issue is and see you as a person, then go with Bogdan T. at TR Miller.

Derrick was excellent. He removed the old heater efficiently and installed the new one the same way. He explained all the minor alterations needed for the 50 gallon tank. He was clean and efficient, and answered all my questions. He had all the tools needed, and cleaned up everything when he was complete. I highly recommend TR Miller for all your heating, cooling, plumbing, etc.

On Sunday, Ryan F from TR Miller came to replace our broken sewage pump. Like Derrick, he was promp and efficient, explained everything, answered all my questions. I believe TR Miller to be an excellent resource for any repair or replacement jobs. 5 Stars.

Nick and Aiden did an exceptional job with installing my new furnace and AC units! They were very diligent and attentive with the installation, and they explained the new system to my wife and me in great detail. They even cleaned up the leftover mess and removed our old units as well. I’m ecstatic that we went with TR Miller for this project!

Such a great experience! I noticed our water heater was leaking the other night. I was able to get a hold of someone around 7 pm which was nice! I was also able to set up an appointment for the very next morning! Omar came out first thing in the morning and was able to replace our water heater in a timely matter! He also cleaned up whatever mess he made! He was very kind and professional! I would highly recommend this company!

The Dream Team at TR Miller – 5 Stars

This review is long overdue. The team at TR Miller was outstanding and truly deserves a 5-star rating. I half-joked that they should give a TED Talk on customer service—they’re that good.

After our AC failed during the hottest part of August, TR Miller had a technician at our home in under 45 minutes. Marvin G. was professional, personable, and incredibly knowledgeable. He clearly explained every measurement and diagnosis and took the time to thoroughly investigate the issue. Given the age and condition of our system, we decided it was time for a full replacement.

Enter Karen O., our Comfort Consultant, who was an absolute pleasure to work with! She walked us through system options, sizing, efficiency ratings, tax incentives, and financing with zero pressure. She even recalculated our needs and recommended a slightly smaller furnace for the first floor—proof she was focused on what was right for us, not upselling. She helped us choose a system that fit both our home and our budget.

Installation day was impressive. In one day, the crew removed two furnaces, two AC units, and two humidifiers and replaced them with high-efficiency, state-of-the-art equipment, plus air scrubbers and a whole-house dehumidifier. The workmanship was exceptional—everything was clean, precise, and beautifully laid out. The system honestly looks like artwork.

Huge shout-out to the installation team:
Steve S, Nick L, Eduardo R, Derek D, David L, and Jocki S.

They were professional, respectful of our home, and incredibly skilled. Jocki even corrected a poorly designed water shut-off configuration at no extra charge—just one example of how TR Miller’s pricing is truly all-inclusive, with no surprises.

Karen stopped by during the install to check on progress, brought the crew lunch, and followed up afterward to make sure everything was perfect. At the end of the day, the team thoroughly explained the system, set up the thermostats, and made sure we were comfortable operating everything.

The result: noticeably better comfort, improved air quality, and peace of mind. TR Miller combines the expertise of a large company with the care and accountability you hope for from a small one!

I give TR Miller my highest recommendation and wouldn’t hesitate to work with them again.

Curtis and his crew are best in the business. Have used them a handful of times. He is always on time,honest and fair with his pricing. I highly recommend him and trust his professional opinion.

The service call was educational: which is important that I understand was is happening. The call yielded great results: I now have my furnance working and my air conditioner operating. I am so thankful that the cost was affordable as I was truly hoping I did not have another big price tag on top of medical bills in 2024.

My family and I have used Curtis for a few different repairs now. Most recent was our water heater. Came out same day and great, quality work.
Thank you so much and you will be hearing from us again!

Curtis is the Most Professional HVAC Tech I’ve Ever met!!! He came ASAP, diagnosed my problem with my AC Unit. He took pics of my ac unit of what issues were going on & showed us. He went over & beyond explaining what’s wrong & what he would do to fix it. He also showed Pics of Before & After. Very Very Courteous & Super Knowledgeable. I Would Highly Recommend him to Anybody!!! I would give him Six Stars if I could. He’s coming Back in the Fall to service my Furnace. Thanks Again Curtis, see you in the Fall. Ed Data, Plainfield Il.

I called Curtis for a second opinion on an older Unico AC system that I had previously been told needed complete replacement. Curtis proposed repairing instead of replacing, and he had the unit back in working order within a few days of his proposal.
He returned calls promptly, explained the problem clearly, answered all my questions, and he and his assistant, Darwin, performed the repair with great professionalism.
I highly recommend CW Mechanical.

Curtis was very professional and kept me updated on everything he was doing! I would highly recommend him! And he was reasonably priced!

We called Curtis to see if he could come out and service our walk in cooler at our business. He was available to come out the same day, and was in our store within a couple of hours. He was very thorough and explained what the problem was and how he needed to fix it. He had all the parts he needed with him, and made sure our system was working properly long before he left. We will definitely be using his services again.

CW Mechanical installed a new furnace for me. CW Mechanical is Professional, honest, reasonably priced, prompt and the work is EXCEPTIONAL. Curtis explained in detail the work that he had done and gave advise on maintenance, proper filters and the warranty. He left the work area super clean unlike some workers that you have in your house. If you are looking for HVAC services, look no further. CW Mechanical is who you should call. We highly recommend!

Mr. Curtis Walker is all about 100% customer

what's wrong with my heating system. He
explained the steps involved to diagnosis my
heating issues. After a comprehensive evaluation,
he gave me a fair quote. Once the service was
completely satisfied and paid. He immediately
handled me with a very detailed description of his
labor and parts/service. He has no gimmicks, he's
a professional who cares about his work,
customers time, home, cost and clean up.
As a repeated satisfied customer, Please don't
hesitate to do business with a professional who is
highly skill with homestead honest values.

Curtis was great! Professional, freindly and explained everything. We called in the morning as our heater just stopped working. Was able to stop by in the late afternoon, and took a look. Easy fix, but still took the time to explain what happened and what he was doing. Highly recommend!!

We had a little issue with our hot water heater and Curtis was able to fit us in the very next morning as it was not an emergency for us. He came on time, as always. He explains what he’s doing and why he’s doing it. If you have any questions, he has no problem telling you the answers. I love his professionalism, his knowledge and he leaves no cleanup for you to do! He’s the best around! We trust his work and will continue to refer him to others.

To date we have been through multiple HVAC techs/repairmen and was always left with the feeling of being let down as a customer. A heating unit was installed and when it failed to work the installer suggested we have someone else look at it and never came back.
The a/c failed to get cold and 5 out of 5 techs advised to replace it.
Mr Curtis was straight forward and honest.
He made no promises and said he would look at it and give a full assessment. His assessment….. the unit was in dire need of service.

It’s cold now and getting colder…. Matter of fact it’s working better than ever!!!

He walked it like he talked it!!

Mr Curtis is a no nonsense HVAC professional and you don’t get that at all from Vendor now days.
Informative, quality service, quality work.

From here on he’s family!!!

Curtis is the best! He came to fixed my furnace same day and on the coldest day this year. He is great at his trade. Professional, reliable and honest. I will never use anyone else but him for my furnace and air conditioner new or repairs. Thank you for making sure my daughter and I have a warm place and at a cost that did not brake the bank!!!!!!!!!!!
