JM Electrical Company, Inc

JM Electrical Company is a Lynnfield-based commercial electrical contractor that's been at it since 1985 — the company describes itself as working with building automation and mechanical contractors across Greater Boston on controls, instrumentation, power and energy-solutions projects, the kind of behind-the-walls work that doesn't always show up as a routine service call. What third parties have said backs that longevity up. A 2026 article marking the company's 40-year milestone credits it with roughly 25,000 completed projects and a national ranking from the National Electrical Contractors Association as the ninth-safest electrical contractor in the country. The customer record, while small, is consistently positive across several years: a 2023 Angi review called the service prompt, efficient and neat; in a 2021 review, a homeowner walked through a Google Nest installation and called the work knowledgeable and prompt, while another 2021 review described a quick office job as efficient and effective; a 2022 review from a Dorchester customer praised professional work and a fast appointment. Google shows 4.2 stars from 11 ratings and Angi shows 5.0 from 4. There isn't much to flag before calling — the written record is short but clean. Given the commercial-controls focus described on its own site, it's worth confirming whether a smaller job like a single install or office repair fits alongside its larger mechanical-contractor work.
