"We found SmartHouse almost by accident while looking for solutions to what turned out to be botched previous AC installation by a much bigger and more established company who we had trusted to do a decent job. Instead we ended up with a system that wouldn't cool the house. Smarthouse first correctly diagnosed the problem, then fixed it, and advised us on how best to heat and cool our 100+ old house. We now have a service contract with them for regular maintenance and they recently installed a mini-split for us. Their techs are great. Just the sort of people we would feel comfortable leaving alone in the house to finish a job if necessary."

"He serviced our HVAC system. House was dormant for about 9 months and for sale. We noticed the system didn?t smell good and wasn?t cooling the house right. So we called him to service our house. He found our duct work to be compromised and pulled out some dead animals. He fixed the ducts and put this shiney metal tape on all the seams. Checked the AC outside for refrigerant gas and operation. Then he checked our furnace inside.

Checked the fan blades with a tool to make sure it was blowing a strong stream of air. Took a shop vac cleaned each of our floor vents and put about 10 or 15 foot of hose going in each direction. For a man by himself he was very"

"Had new hvac, furnace, and hwh installed. Furnace had a couple of air leaks between a coil and furnace which I fixed myself. Hvac was spot on. Hwh failed first inspection, but was corrected in same day. For the premium price paid, these issues should not happen. Quality 4.5 because of these issues, same goes for value. Customer service is very good. They are very professional, work looks very good, clean worksite afterwards. I would recommend, but don't think about negotiating price with them. Their labor is very high."
