Great service
Alison - Chicago, IL 60647
Job well done!
TDH guys are so professional on installing the HVAC unit on a pitched roof. They even sealed the duckwork connected to the main unit. The price is reasonable too. I’ll definitely recommend this company to my friends.

TDH Mechanical and Wally Wojtowicz
We initially contacted TDH Mechanical due to two neighbors who recommended them. They were correct in their recommendations. We got Wally Wojtowicz and his co-worker for the project. They were professional workers. They worked all day with only lunch breaks to complete the project. They provided through workmanship by minimizing the size of holes cut into drywall. He explained how to do the dry wall repair so the room would not get cold. He was considered for us as customer by starting the project at 8 am instead of 7 am. They cleaned the work area every day to avoid disturbance. We would recommend TDH Mechanical to anyone looking to install or repair mini split units and refrigeration lines.
Jose Gonzalez - Chicago, IL 60641

Phil - Chicago, IL 60657

Thoughtful. Helpful. Easy-going. Effective. Fast.
Leslie - Chicago, IL 60653
Feels like I’m being taken
3 years after installation, something failed and had a warranty call. Tech came out same day (great), but then said the wiring failed and he did a temp fix by disconnecting the heat and applying the wires to the AC. Told me $250 for today and another $450 to come finish the job. Angie’s list says it is a $120-200 job total and that is assuming it wouldn’t be covered by the warranty, which it is for 4 Seasons Heating & Cooling (their competitor). So they want $700 for something that should be free. Ridiculous.
Scott - Chicago, IL 60622
Quick and Knowledgeable
Diagnosed the problem quickly and made the repair smooth
Toby - Chicago, IL 60657
Long day, great work!
12 hour day, full AC and Furnace install, including a crane to get the unit to the roof! Excellent job! Couldn’t be happier!
Toby - Chicago, IL 60640
Considered about the quality of work
I sent a photo of the problem ahead of time but when technician arrived he said he could not service the machine because of the drainage pipe. We eventually convinced him to provide the service because he said he was going to charge us and not do it. Afterwards, he didn't explain anything from the inspection. And the information I could understand like the outside temperature was not accurate. It said the temp was 96 but it was only in the 70s. I feel like I paid 85 for nothing.
Hannah - Chicago, IL 60618
Super Knowledgeable, Right on Time
Kris is great. He’s serviced our navien boiler a few times now and I appreciate that he shows up at 7:50am for an 8am appointment. I also recognize that preventative maintenance isn’t the most exciting part of the job. He still takes it seriously and it’s clear he genuinely cares about his work and our reliable access to hot water!
Scott - Chicago, IL 60622
Excellent service!
Wally was diagnosed the problem with our cooling unit promptly. He scheduled the next job promptly for the following morning which will be a great relief to our staff and clients.
Reginaldo - Chicago, IL 60640
Excellent service
TDH Mechanical overall was very satisfying to work with from setting up initial appointment to view the work to be completed, very competitive proposal quote, and the installation by Alfredo who ensured i knew from the beginning the work to be completed and the timeframe it would be completed. Very professional to work with. Additional item, I would occasionally hear back from the company as I was evaluating all the proposals which indicated to me that I was more than just another customer contact in a database. There were no surprises before, during or after and received the best labor/equipment/install price from this company; highly recommended?
Earnell - Chicago, IL 60643
Excellent and fast service
They came right away on a busy weekend. The technician was very politey and knowledgeable, and the price was very reasonable. Will use them again for sure.
Olga - Chicago, IL 60613
Great service! Very response.
Everyone from Rolando, Mark and Tim were great to work with. Very responsive and consulted with me to give me options of how to service/replace the furnace. Would highly recommend them. My mother and sister have also hired them for work and had recommended them due to a positive experience.
