Typical Greater Boston range for this kind of work, from regional averages — not a quote from Arm Mechanical. Use it to sanity-check bids, then get the real number in writing.

Good guys, good work, good experience.
I recently had ARM Mechanical install a boiler and mini-split system in my home, and I couldn't be happier with the experience. Their professionalism and the price that couldn't be matched by other contractors really stood out. The technician was super knowledgeable and friendly and explained everything clearly throughout the process. They finished the install on time and left everything clean which my wife certainly appreciated. I would highly recommend them for all their services, they are great!
