"We hired Smarthome to insulate our attic. They were not the lowest bid, but their expertise, particularly about the various insulation options, convinced us to go with them. And I am so very glad that we did. Not only did they do everything we expected in terms of insulating our attic, they noticed that the duct work in our air conditioning system had not been properly sealed. We had been wrestling with the unit's inability to cool our house for years, and our regular HVAC provider told us that this was the best the system could do. In fairness, we have an old house and a complex air conditioning set up. Smarthouse both diagnosed the problem and undertook the necessary fixes for a very reasonable price. As a result our house is markedly cooler and our electrical bill has come down a bit. This is a great company. They know what they're doing and they genuinely seem to care."

"Excellent! I love JT Dunn Heating and Cooling. We selected them out of 5 different contractors to install our brand new furnace and conditioner in 2017 and we hadn't had a problem since. We just had a 3 year tune-up and nothing was wrong and the ac is quietly humming away outside. Thanks to employee Robert Fitzgerald for coming out today and doing a awesome job and keeping us as customers!"

"I got several quotes for a full dual zone Central Air install on our 100 year old house, and this came in as the lowest, plus it included all carpentry and drywall work, which the others did not. The fact that they also do home restoration was a big bonus, since the guys they brought to put in our new ceiling (we dropped the ceiling in the hallway to accommodate the vents) were professionals and did a great job. Jed was friendly, trustworthy, flexible and made sure we were taken care."

"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."
