TDH Mechanical Heating & Cooling Contractors

We were very happy with our decision to contract with TDH. The two-man crew were on time, courteous, answered questions and very efficient. Felt the project (new furnace and air conditioner) went very smoothly.

Excellent, absolutly amazing, quick response, quick estimate, fair price and installed. Tim is the owner, very knowlegable. Very neat and respectful of your home, Mark & Videl were awesome. This company is JUST GREAT

they did a lot of work did a good job for a very low price , A company that will do what you want did an excellent job

I had a great experience with TDH Mechanical. They did a full HVAC replacement of 2 systems in my single family home, including furnace and air conditioners. They were highly consultative and patient during the selling process, all work was completed on time with high quality, and the team was neat and courteous. When the units needed a bit of tuning post install (normal), they were back onsite in a matter of hours. Tim, the owner, is hands on and responsive and proactively checks back in on how things are doing. Would definitely recommend them to friends and family.

This is by far the best company I've ever dealt with for HVAC... They made an appt to come out at 7am to replace my boiler and they were here at 6:50am. Jorge was awesome I would highly recommend them. A+

Their service was very good; they always come when I call for service; every time I hear problems on my furnace or air conditioning, they always check and make sure that everything is working well.

Went very well. TDH services my two furnaces and one humidifier every autumn to assure trouble-tree operations. Their technicians have always been thorough, knowledgeable, efficient, friendly and professional; an this year's visit, by technician Gelacio, was no exception. Together with TDH's fair price, this keeps me a satisfied customer.

One of the larger HVAC companies in Chicago told me I needed a new boiler to the tune of $8000, but something smelled fishy to me. On a referral from a friend, I called TDH, and their technician came out and checked out my boiler and told me there was nothing wrong with it. He also told me that the other company pays their technicians COMMISSION on anything they sell, producing a huge conflict of interest. TDH did some minor maintenance on my boiler for a low/reasonable rate and saved me close to $8000. Thanks TDH!

Excellent communication from both sales office and the onsite mechanics. Professional, hard working, and I am very satisfied with the quality of work performed.

Tim was amazing! He sent a crew the next morning after my moms furnace broke down! His pricing and customer service are outstanding! Returning all my phone calls and text messages! Thank you so much!

These guys are great and were definitely the best value. Very knowledgeable and up on the latest technology and research in home comfort. We discussed some possible upgrades to improve efficiency and comfort and I was very confident in my decisions. Installers were professional and hard-working. The owner, Tim, is a really nice guy and I didn't feel rushed or pressured as we were talking through the options. Office staff was on the ball with gentle (not aggressive) follow ups. Also, TDH Mechanical guarantees the system for 12 YEARS parts AND labor!!! So if something, anything goes wrong with the system (other than you bashing it with a hammer or like your basement flooding) they come out and fix it at NO charge. That sealed the deal for me. It was refreshing to see somebody stand by the product and workmanship like that. I give them the highest marks.

I don't know how other HVAC companies compete against TDH. Put in a top brand (Trane) 2 stage for the price others were quoting me for a mid brand one stage. The Installer (Mark Keenan) found a world of hurt when they pulled the old unit out and crafted a great fit on the spot with fixed space limitations (with a trip to the Home Depot). Instead of 5 hours it took 7 to finish the job, did not even ask if he could charge me more - which I would have understood.

Process was very smooth. Short phone text with a quote. Appointment arrangement.Punctuality on the day agreed. They did the job expected. Very efficient. Alfredo did a very good job installing the humidifier in my basement and he did the right recommendation for the humidifier at the second floor. He also clean the ducts. Everything in around 4 hours

Tim and his team exceeded every expectation I have. I am an educated consumer of home improvement services and have contracted for numerous projects over the past 10 years in a 100 year old bungalow. The TDH team was the easiest and by far the best to work with of all contractors. They responded within an hour to my initial request and was on site the same day to inspect the site and assess my needs. We discussed numerous options at all price points and decided on a complete replacement of the water heater, hot water heat boiler and the piping. I had final quotes in less that 3 hours and they responded within hours with any question I have. They were able to schedule the work within 2 weeks. The On-site team of Chris, Bernie, and Zeorge also installed a two zone system with computerized controls attached to two smart thermostats. The work was scheduled to 2 days of on site activity. The team arrived exactly on time, 7AM,on the scheduled day. They laid down drop cloths and 100% of all debris and trash was removed. They were completely done by the 2nd day, on schedule. When the work was done, the job site was spotless, Chris did the walk through and review of all the new equipment, answering every one of my numerous questions. The work was flawless and neat. Very professional. Tim, Jim, and his team set the standard for how contracting work should be done, from the first contact through the end of the project.

TDH Mechanical set the bar high! I happily give my highest recommendation. Tim contacted me and went above and beyond, breaking the ceiling in my satisfaction of his knowledge and the service provided. TDH will not disappoint!

TDH was very good at handling the removal and installation of a new HVAC unit in a crawl space. They were knowledgeable and only wanted to provide me what I needed and not try and sell me the most expensive. The installers work very had and were very clean. They've earned a customer for life.

Louis came out to give me an EXCELLENT quote. Kris & Ceasar did an outstanding job on installation. Owner Tim Hancz phoned me to see how things went. 5 STAR all around !!!!!

I was able to reach Jim right away, and he immediately got me a quote (the best price I found) to replace both of my furnace humidifiers. I was on a tight schedule because of a home closing, so he fit me in the next week. Hector showed up as scheduled, was very friendly and professional, and was very clear about the work he was doing. This was an excellent experience from start to finish, and II would definitely use TDH again.

Tim responded almost immediately after submitting my request for contractors. Good price, very friendly and a great warranty. Install went very smoothly. Crew was on time and finished before I expected.

I got 5 quotes for a new furnace and AC in Uptown Chicago and TDH was the lowest and most responsive. Tim responded to my questions and got back to me over the weekend. I hired them and they installed the new units that week. His team was professional and did a great job and I would definitely hire them again.

3 months after they did HVAC inspection, HVAC broke. During visit, we asked for estimate of repair twice, never given, repair made and presented with $1200 bill. Company refused to work on this despite comparable prices. Terrible customer service. After their visit it was discovered that electric wiring left disconnected— required another visit to fix (by another company). Then i found they put air filter in with wrapper still on.

They arrived on time and worked quickly with replacement, installation and cleaning.
