Mass Generators is a Weymouth shop built around one thing: whole-house standby generators, sold and installed as an authorized Kohler dealer. Its website describes the company as family owned and operated, serving homes and businesses across Massachusetts and New England. Eighteen Google and Angi reviews running from 2016 through this year are unanimous — every one five stars — and owner Don Noll is named by name in almost all of them. A 2026 review has Kohler-certified technician Brady diagnosing and replacing a failing battery the same visit a generator quit; another recent review describes a full standby-generator install with extra electrical wiring finished the same day, plus a callback later to fix an unrelated breaker at no extra prompting. Repeat business shows up too — in 2022 and 2023 reviews, different homeowners describe calling Don back for annual maintenance or another electrical job after their original install. One customer, writing in a 2021 review, called Don "the G.O.A.T. of generators" after office manager Janice fielded the first call; shorter reviews across the years repeat the same themes — quick estimates, on-time appointments, the install explained step by step, and a jobsite left clean. One thing worth clarifying before booking: the website advertises 24/7 service, but the company's Angi profile states it doesn't offer emergency service or free estimates — so this reads as a planned-installation specialist rather than an emergency call, and it's worth confirming turnaround and pricing up front. For anyone weighing a whole-house Kohler or Generac system, the decade-long record here is about as consistent as they come.
“Great service, pricing and process”
Highly recommend this company, 5 Stars in every way!
Mass Generators, LLC, came to service my Generac house generator today, that had stopped working. From the first contact with Janice in the office, everything was handled friendly and professionally. The technician that came today was named Brady and immediately diagnosed the problem with my battery, performed the full inspection, and maintenance upgrade, and had me back up and running in no time. As a retired architect, with 45 years experience, I’ve encountered a number of contractors along the way, and this outfit certainly shines in their field. I highly recommend them for your generator needs.
Don and team installed a whole house standby generator for us a couple of days ago. I had a very good experience with Mass Generators--very quick to get me an estimate, great communication, fast and high quality install, neat jobsite. The team was warm and had a good sense of humor. It was fun to have them at the house for the day.
Had a great experience with this company and Don the owner. Great communication and in installed my Kohler generator with no issues. Did some extra electrical wiring I needed the same day and it looks great and is much safer! Was very professional and explained everything very well and answered all my questions. Also called back quickly and even came back out at a later date when I was having a small issue with my main breaker and fixed it. Would definitely recommend and will be using them for future maintenance and electrical needs!
Don and his team are very professional and extremely knowledgeable about the various generator lines they install and support. They're punctual with their annual maintenance programs, and when needed, very responsive in addressing issues and or concerns.
