"He explained how they would design and install the new furnace and all the zones. He obtained new hot water heater at no additional cost as well as the available rebates. The actual installation was accomplished in one and a half days. Everything was done very professionally and the area left totally clean. He"

"I recently bought a house and needed a new furnace and I wanted to add central AC to my house. I have a friend who has been a contractor for 20 plus years in the town I moved to. I asked him who he uses, he said he only uses Druziako. I called them up and they came out gave me all my options and advised me on the best way to add duct work etc. They gave me a date they would be there and said it would take 2 days to complete the install. They showed up on time. They finished it in 2 days. Guys were professional and clean. The whole project came out better than I expected. I couldn't be more happy. I would recommend them to anyone. I would also recommend central AC to anyone. It's a nice gift to give yourself :)"

"Excellent. I've had Genove install both gas and oil heating systems in my properties, most recently oil. They have also installed central air/hydro air and handle my oil delivery. The techs have always been polite & knowledgable. Their customer service is impeccable. As a landlord/home owner, I couldn't be happier with them handling all my HVAC needs and would recommend them to anyone."

"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."

"Great experience with Milltown. Their sales manager Jason came out twice to meet with me personally and tailor a proposal to my needs. I had some non-HVAC ancillary work needed (ice maker line) and they were happy to incorporate this. On the day of install, Derek and the onsite team were friendly, professional, and responsive to all of my questions. Price was competitive with two other bids I had solicited. I would highly recommend working with Milltown and would work with them personally again without hesitation."

"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."
