Easy Scheduling + Install

I got a referral from a neighbor who replaced their HVAC system with TDH and went with them over two other contractors, as they provided a better quality unit in the spec and at a better price. The installation went quickly, and the new system is a huge upgrade from my 17+ year old one.

Excellent

TDH quoted us for a new AC and furnace after ours died during a hot spell. They were priced better than the other quote we received and their team installed everything with respect and efficiency. I am grateful that Wally the technician took time to communicate with me throughout the day and explained the parts, the mechanics and maintenance going forward. Highly recommend.

Great team!

Our installation team of Wally and Chuy were wonderful. They had our furnace and A/C installation completed in amazing time. Very informative as I asked questions (I tried to get out of their way!) we are more than pleased with the TDH team. Thank you

No surprises

TDH did what they said they would do for the price they said they would do it and the equipment and installation is top notch. The TDH quote for all new heating and cooling equipment and installation was my 2nd quote and it was way way better than my first quote. Very good people; friendly and respectful. I have already started recommending TDH to my neighbors in my condo building.

My Go-To for All Heating and AC Needs

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

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

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.

Clean Professional Install of mini split and water heater.

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.
