Review: TDH did an installation of 6 ductless air handlers for an office. They were very efficient and worked around our office availability to get the work completed on time and at a reasonable price.Excellent communication and tidiness throughout the project were above expectations and appreciated. Wally and his crew were on time and easy to work with. Would highly recommend them for professional quality work and craftsmanship.

Review: Called TDH and it was a pleasure dealing with Wally. We received quotes from other companies just to receive the same old story from every salesman. Wally came out, was incredibly knowledgeable and was also onsite for the install to ensure everything was done correctly. He was not just a sales guy. He’s part of the install team and I appreciated that. Our friends have used their services multiple times and we will too!

Review: They cleaned my AC unit after another firm I had called left my unit dirty even though I had called for a AC cleaning and spring checkup.
The other firm’s technician claimed I had multiple things wrong with my unit and I needed to shell out a minimum of $600. And he then kept going by telling me I should get a package deal which guarantees certain things for $1600. I said no thanks and told him I’d be calling the firm that installed my unit. He then told me they aren’t really supposed to clean a defective AC unit and he wasn’t kidding as he did a terrible job of it. And this company’s policy is that they no longer open the top of an AC unit to clean out all the leafs and debris.

Review: You can see the obvious upgrade from my 20+ year old HVAC system. I am a repeat customer to TDH. I bought a Trane Furnace from them in February in prep for putting our suburban home on the market. We now live in Chicago and we purchased a condo with a very tired HVAC system. We got three quotes – TDH was not the lowest – but better cost than the Carrier supplier. Also my Trane furnace was assembled in the USA – this means allot to me. Great installation team today of Julio, Javier and Luis! They really did a great job, cleaned up well and made sure I was happy. Note: I had an existing humidifier and Ecobee 4 smart thermostat. TDH was great about letting me re-use those (as both almost new) – saving me time and money. Also the Julio made sure the Ecobee was re-programmed for the 2-stage furnace and also humidifier control! Also my new HVAC comes with a 12 year warranty from TDH!
