My Go-To for All Heating and AC Needs

Jon from Chicago, IL

I use TDH for my personal and rental properties. They are family owned and honest. Also, you’ll find their pricing can’t be beat.

Excellent price and no frills

Gina from Lombard, IL

We priced a couple furnace and AC systems and TDH was the best price and they didn't try to add a bunch of extras to the systems. They were clean, friendly and efficient at installation. Highly recommend.

Best Service - Best Technician

Erik from Chicago, IL

Firstly, there is consistency. TDH techs are all good. But having the same one for 15 years is outstanding. Wally has installed our furnace, tankless hot water system, radiant heating in floor and ceiling. Secondly, the work Wally performs not only is outstanding but the details in laying out the radiant system is a thing of beauty. Shows the care that TDH puts into their service. Thirdly, is consulting on complex projects - TDH (Tim and Wally) did great work in consulting on the design. Few in Chicago would even quote on our needs for a tankless hot water and radiant heating. All of the recommendations worked out perfectly. For service Jacquie is always responsive - and on the few times over the years we’ve needed service she has been fast and very communicative. Highly recommend TDH for any HVAC needs.

Amazing service!!

Fantastic service, competitive pricing, impeccable workmanship

Clean Professional Install of mini split and water heater.

James from Chicago, IL

Great experience with installation of a new multi-zone mini split system (with lines on brick work in a tight space) and water heater. Work was done super clean with basically no debris, and looks super clean and professionally installed. Was super understanding of working with animals in the house. Also went the extra mile in installation without being asked to (but did prompt to confirm), for things like lifting the water heater to drain it, cleaning up existing water lines, and adding air redirection on top of the neighbors outdoor AC to make sure the air doesn't get trapped under the deck. You do pay a bit more for the service, but it's worth it to pay a little more up front to not have to worry about it for the next couple of decades.

Professional

Vin from South Elgin, IL

Wally and his assistant did an outstanding job replacing my old Furnace and AC condenser. Kept my home clean the whole time.

Excellent AC installation!

Victor from Chicago, IL

Wally and Jesus at TDH spent three days installing coils and condensers for central air conditioning in the front apartments of our 1880s building. They solved some tricky spatial and technical issues along the way. The price was more than reasonable and the best of the quotes we received. The office staff even sent someone to pick up a check when my bank fouled up the final payment. Highly recommend from bidding process to installation and accounting.

TDH is great

Brieanne from Chicago, IL

TDH Mechanical installed the HVAC system in our home twenty years ago before we even owned the house. When it was time to replace the equipment this year they were a very easy choice as they have been a very reliable and steady company. No question I would recommend them.

Great Experience

Kevin Bricknell from Batavia, IL

TDH Mechanical Inc. installed two Carrier furnaces, AC units and Aprilaire humidifiers in my home and were very professional, thorough and detailed in their work. Reviewed bids from 5 different companies and glad we chose them. I would highly recommend TDH Mechanical.

Great service

Benny from Lake Barrington, IL

Excellent, professional service

Alicia from Chicago, IL

Wally was prompt, intelligent and fixed our furnace as quickly as possible.

Great service, great price, poor customer support!

Peter from Park Ridge, IL

We took advantage of a pre-season sale on new air conditioning equipment. When we accepted the TDH proposal we requested 2-days notice for installation. A week later we again requested an installation date. Eight days later the installation crew showed up at 0730 without notice. Since TDH had arranged for the Carrier distributor equipment delivery we accepted the unscheduled installation. Since we had scheduled our spring cleanup by our landscape service for that same day the landscaper was not able to fully service our yard because we had old and new AC equipment, tools and other parts in our yard.

Excellent service!

Pat from Chicago, IL

Wally was great! He is very knowledgeable about the heat pump gas furnace and thermostats, figured out the problem and solved it!
