"I needed to replace my parents' 40 year old AC Condenser and coil, and replace it with something that worked with the new furnace my father got installed four years prior. They were able to do the work requested, and also offered to redo the furance installation as the previous company installed it right on the basement floor where any backup/water could possibly get into the system. They were very prompt and showed up on time/on schedule. They were very upfront about costs and pricing and there were no last-minute price changes or hidden fees, which I appreciate. Work was done well and they ensured that everything worked before leaving the job site. The gentlemen working were very professional and understanding. I highly recommend them for anyone looking to replace their HVAC or to correct work that was previously poorly done."

"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."

"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."
