Dear Sir, I am very pleased with the prompt response and conscientious service received. Kris was the service representative. I found him to be competent, courteous, clean, & friendly. He answered all my questions & addressed my concerns in a very professional manner. I will recommend your company without reservations.

Review by Richard L. in Chicago, IL
This company was very professional when they came out to give their proposal and offered more that the others and for less money. They were to come out in the morning, but called to say that they would not be out until 3 pm which was disappointing, but they did come late on time as promised. They did not request any money until the job was completed to my satisfaction.

Jeff M. Highland, IL
TDH was extremely professional. They were prompt, removed our furnace and a/c and replaced them with much more efficient items. They took care to protect our floors and were very friendly. Their bid came in well below 3 other competitors for superior equipment. I would highly recommend them to others.
