Communication was clear throughout the process, and the pricing was fair. Highly satisfied with the quality of work and customer service.

"Nicely done. We have two Carrier furnaces in our old house. I phoned Air Solutions for an annual inspection/clean on both units and they had a man available the same day. Very nice tech, good communication, no issues, and they let us use the Angie's coupon on both units. Will definitely hire again!"

"I got 5 quotes for a new furnace and AC in Uptown Chicago and TDH was the lowest and most responsive. Tim responded to my questions and got back to me over the weekend. I hired them and they installed the new units that week. His team was professional and did a great job and I would definitely hire them again."

"Veteran Air Cleaning Services was great to work with! We bought a new house, and the former owners had pets. After the vents were cleaned, the house smelled fresh. No more dog smell. When Josh and Kyle came, I also had electricians working in the kitchen. They were able to work around the other people, as well as keep me informed of everything they were doing. Their communication went above and beyond what I expected. They explained the tools, then walked me through how to use the furnace humidifier, and how much longer our filter should hold out. I plan to hire them again."
