A mini split quit; Chadi drove a long way to get to it and had the house cooling again about fifteen minutes later. Every one of NuTech's written reviews makes the same point about timing — he comes when he says he will, often the same day. It goes the same way on the heating side. In a March 2026 review, a homeowner with a non-urgent gas furnace problem got same-day availability and mentioned that Chadi wiped his feet every time he came in, which they said many service people skip. That customer also felt he had not been over-charged, and that he was told which items were not urgent. A December 2025 customer said he arrived as scheduled, fixed the problem, explained what had caused it and talked through complications that might come later; another writing that month said he came right away, diagnosed the issue quickly and kept the customer informed. Thumbtack lists NuTech in Norwood as one year in business with 59 hires and a background check, and its work as heating repair and maintenance, central air conditioning repair, thermostat installation or repair, and duct and vent repair — the profile says oil burners are excluded. The Angi listing at 185 Washington Street adds free estimates and Spanish-language service. On Thumbtack the rating is 4.7 across 26 ratings: 84% five-star, with one 2-star and one 1-star among them. For a mini split or a gas furnace that has stopped working and needs someone today, this is a sensible call. Say which system you have when you book, since oil burners are off the list, and ask what the visit costs before he drives out.
Responded very quickly and drove quite far to fix my mini split. Had it chilling my house in about 15 mins. Excellent response and work!
Chadi had same-day availability for non-urgent service on my gas furnace. He was punctual, respectful (wiped his feet every time he came in, which many service-folk don’t do), and efficient. I also felt like he was honest and didn’t over-charge me. Told me things that weren’t urgent that we could address next time. I will definitely utilize his services again!
On point! On time! Knew what he was doing and well... Nobody likes to pay but... the heat is definitely worth the cost. HIGHLY RECOMMEND this technician and his services…
I had a great experience with Chad. He was punctual, communicated clearly throughout the process, and came right away when I needed help. He quickly diagnosed the issue and fixed it efficiently. Professional, knowledgeable, and reliable! I would definitely recommend his services to anyone in need of HVAC repairs.
Chadi from Nutech arrived as scheduled, fixed the problem, explained its cause, and discussed potential future complications. I recommend him to anyone experiencing HVAC issues with their mini-split reversible air conditioning systems.
