"They did a fantastic job with the installation, and even installed a WiFi-based thermostat that increased the efficiency of the fan and dehumidification capabilities of the new system. We did call around to get quotes/bids and pretty much all the shops in town wanted to charge about the same so we feel the price was very reasonable."

"The inspection turned into a new furnace and air conditioner. I decided to take advantage of their special of $1000 off if you replace both. Mine were old enough so that I decided to replace rather than repair. Technicians were very pleasant, knowledgeable, and professional."

"Went great, poor guy had to go into the attic to put in new mounting box. Hot up there. Was very professional and fun to talk with. Explained what he was doing and gave us mounting choices on the fan. Would definitely recommend for projects in the future."
