KNC Mechanical

KNC Mechanical is a Braintree-based mechanical contractor working plumbing, HVAC, and boiler systems for commercial, multi-residential, and industrial buildings, with a self-reported family ownership going back roughly 70 years and 24/7 emergency service added over the last decade. The one detailed account in the record is institutional, not residential: a 2014 trade-press feature describes KNC replacing the boiler room and 120 heating units and helping renovate 50 bathrooms and kitchens at Chapman Arms, a historic 50-unit apartment building in Harvard Square — all while the building stayed fully occupied. The written customer record beyond that is thin and mixed: a 2023 review describes the workers as rude and aggressive, and a 2021 review describes a company vehicle driving recklessly through stop signs in Framingham — neither describes the mechanical work itself. A 2022 five-star review is enthusiastic about their heating and cooling but offers no specific job detail. The company's BBB profile carries an A+ grade, though BBB notes it is not an accredited business and the profile lists no customer reviews or complaint history. For a commercial or multi-unit mechanical project, the Chapman Arms work is a real, if dated, example of scope handled. Given how thin and conduct-focused the residential-facing reviews are, it's worth asking directly about current crew conduct and getting references from a comparable recent job.
