"We could not have been more pleased. We needed to replace our first floor AC, which is a split-type ductless system, about 17 years old. We had an idea of what the cost would be from an online site: [*** Link removed ***] We got 4 bids, 3 from A rated Angie's List contractors to install a Mitsubishi system (top of the line). Except for one, which was off the charts, the bids weren't that far apart. While Unique was not the lowest bid, we chose them for three reasons: (1) Jason (their rep) was the most savvy about the Mass Save and Mass CEC Air Source rebates, which were quite significant (he handled all the rebate paperwork for us); (2) Unique was able to do the job in a week; and (3) Unique included all the electric work into the total bid (rewiring was required). The installation team (John and Quinn) was excellent. It took them a day and half, They were quiet, neat, professional, highly respectful of our homes and proud of their work. We had worried that they would have to remove wooden ductwork which had been recently painted, but they managed to snake the new hoses through the existing ductwork without disturbing anything. Unique had an electrical contractor on site who replaced the breakers on our electrical panel, installed a higher capacity wire from the panel to the AC system, and replaced the cutoff switch on the outside. We were quite pleased with Unique's work, and would definitely recommend them to others."

"Dylan was amazing. My hvac person retired & I found Dylan when my Central air decided to act up. He explained my unit was in approaching its last days but he could attempt to repair it if I wished but I decided it was time to do a complete new heating & cooling system & he made it a easy process. No pressure & no stress. Now we’re ready for the heat wave that’s apon on us. Thank you Dylan & your team for your professionalism & great service. I highly recommend & they’re my go to for plumbing as well as I’m about to have them replace my hot water tank before it becomes an issue"

"I needed to replace an older AC unit that is in a very tight spot in an attic. I had 4-5 people out to look at it and I thought Atlantic (Bill) was by far the most knowledgable and had the best understanding of what I needed, and did the best job explaining it to me. Their pricing was about the same as everyone else so that was the reason I went with them. After we scheduled the install I didn't hear from them until the day before (a Sunday) when I had to reach out to the office. But other than that the installation couldn't have been smoother. Kyle and his team were exactly on time each morning and were very nice and professional and got everything installed smoothly with very minimal need from me. Would definitely recommend."

"The installers were great, removed the 70 year old crumbling boiler and all the old valves, expansion tanks etc. and installed the new boiler and hot water tank in just 2 days. They explained what each valve and control did after they finished the installation. No extra charge for removal of the old equipment and they left the basement cleaner than when they arrived."

"Expensive but professional. The electrician that did the work was excellent and seemed.to enjoy explaining what he was doing and why it had to be done that way. I felt like I learned something while he installed ceiling lights. He also cleaned up after himself like he'd never been there."

"David Sampaio from SumZero was one of six contractors we interviewed for central AC replacement. David was very helpful in our decision making process when we were deciding between AC and heat pump units. His price was very reasonable too. We chose the heat pump in the end and are very happy with the choice. David’s team was very polite and professional during installation, they did an excellent job setting everything up and cleaning the area. High five, David! Thank you!"
