Heating & AC Service in Chicago

Rolando is the best TDH technician. He is very professional & knowledgeable. He was especially careful working in our home making sure his work area was clean.

Very polite, knowledgeable and professional

On time, courteous, fixed the problem inside of 15 minutes.

Kris has serviced our AC last year, and he is always efficient and professional.

Rolando called in advance to advise me of his ETA, and arrived on time. He was courteous, efficient, and completed the AC check up in a timely manner. He gave me good advice to delay the furnace checkup until the Fall since I had no need to use it during summer months. TDH installed my AC unit 6 years ago and has serviced it annually since. I’ve never had any issues and they have been great to work with.

Ken was great, thorough in knowledge, did all Informed him of asked concerning issues, Thanks!

Ken was great and knowledgable about the work he was completing. He helped us determine where our AC Unit was located in our building although we were unable to identify it prior to him helping out which I felt terrible about. TDH has always been a helpful company as they originally installed the HVAC system of the unit we purchased. I highly recommend them for your Heating/Cooling needs.

Ken was super helpful and explained various approaches we could take. I have worked with TDH for close to a decade, and will continue to do so based on my recent experience.

Communication was great, service equally so.

Mark who installed my new system was really professional. He answered all my questions along the way. Rolando who came out for the quote was a great guy too. The overall quote for the equipment was great and they installed two days after the quote so very timely.

Ken was very informative and responded very well to all of our concerns

Chris was awesome,

Our furnace needed some repair, Kris was kind and efficient, and our furnace issue was resolved. Thanks!

In advance of scheduling my service appointment with TDH Heating & Cooling, I did, of course, consult numerous online reviews. The consistency of top ratings gave me confidence that engaging TDH was the way to go. Still, I was amazed by the high quality of service experience in every respect. It started with Tim as attentive listener, then flexibly putting on the rails a timely house call. Rolando came out promptly and proved very courteous, skilled and knowledgeable about the problem issues under consideration (furnace service, malfunctioning humidifier, valve replacement, overall condition assessment and recommendations for equipment replacement). His problem resolution skills and customer focus were excellent. The price was great and turned out even better than fair. Give TDH a try! You won’t regret it.

So professional

My 2.5 yr old furnace had stopped working and TDH was able to quickly send someone out. Technician Kris did a great job and got it running again. He was knowledgeable, courteous and professional.

Very polite and Quality service. We appreciate all the hard work in replacing our boiler and giving us heat again.

Had to reschedule last minute and TDH easily swapped me to the next day with no problems.TDH installed my navien two years ago so having them back for maintenance was a good decision.

The workers were all professional, worked hard and were very thorough. Kept me up to date on the process and walked me through all potential options.

Exceptional service

Always good to get a second opinion. Thanks Kris!

Was getting announced on a tank with water heater unfortunately the condo was not in a position to have it done but they were very professional in their presentation and try to look for alternatives so I appreciate it their time and their service.

Roland’s was awesome. Thank you very much!

Always trust TDH for HVAC needs. Kris called when he was 45 min out and arrived on time. He clearly explained all options for me for my issue.

Rolando, did an excellent job as he took his time explaining the situation about my HEATING system.

He came on time and provided good service

Really fast response when I called. Problem was diagnosed and repaired with my HW boiler. TDH is fairly priced on service and installations. Good operation.

Our furnace keeps having problems. We are looking for a replacement. Willy, from TDH, came to our house to provide an estimate. He is friendly, knowledgeable and provide competitive and comprehensive quotes

He knocked on the counselors doors before entering and thanked them afterwards. He spent the time to let me know how the ductwork runs in the building and what he recommends to get a more even heat distribution. All in all was a good experience.

The rep showed up on time, was very thorough, answered all questions, & was very nice.

Our tech was not only speedy and polite, but was super informative on how we could ensure we were taking care of our furnace going forward. Great service!

Extremely fast arrival, and resolution to problem. I was provided detailed information as to what the issue was and parts were obtained within an hour. Overall process was 2 hours max. I'm very pleased.

Ken came and was very respectful and professional. Gave us a very reasonable estimate for equipment installation and explain everything in detail.

Rolando did an excellent job getting my humidifier and furnace in fine working condition again. He answered my question about humidifier settings with a clear explanation and explained what was going on with my humidifier and furnace and why they were weren’t working and what he did to make them work again. He was right on time for my scheduled appointment.
