McMillian Electrical Services is John McMillian's Cambridge, MA electrical business, and the 21 reviews on file — all five stars, all from 2025 into 2026 — describe an unusually consistent pattern: honest quotes that don't creep up, careful work, and the kind of communication that makes bigger jobs feel manageable. The specifics range from small to substantial. A 2025 review describes a service upgrade from 100 to 200 amp alongside converting standard outlets to ones with USB and USB-C ports built in. Another describes rewiring an entire garage's outlets and installing new LED fixtures, professional from the initial consultation through the final inspection. A March 2026 review describes a small Tesla wall charger install handled with the same patience John brings to bigger projects. One reviewer specifically credits him with old-school integrity: his estimates hold even when a job turns out to be harder than expected, and his quotes are described as always matching the final bill. Another describes him working through an unrelated neighborhood power outage without missing a beat, then cleaning up the work area — down to dust bunnies — before leaving. The reviews keep circling back to the same handful of qualities: responsive, punctual, fairly priced, and willing to take on small jobs that bigger companies turn down. Several reviewers describe using him for more than one project and recommending him to friends and family. Angi and HomeAdvisor both show a perfect 5.0 rating from 21 reviews and both list a Massachusetts trade license, number 13678, running through July 2028, alongside 16 years of experience. Both directories also note he does some handyman and small home-improvement work alongside electrical, though the specific reviews here are entirely about electrical jobs — panels, wiring, lighting, and EV chargers. For electrical work of almost any size, from a single light fixture to a full service upgrade, this is about as consistent and specific a record as a residential electrician gets.
Great Service
He fixed the problem to my satisfaction for a reasonable price, and enough said. I appreciate "Angi" but I don't appreciate the A.I. version of "Angi" wasting my time.
John is such a great guy to work with: responsive, punctual, honest and patient. I have worked with many contractors over the years and John is the only one that actually deserve all these four words. My project (installing Tesla wall charger) was not a big one but John took the time to stop by before the installation day to check on the charger I bought and made sure everything was fine. Some other electrician has suggested using #6 Romex wire for the 60 amp charger but John went with #6 metal clad wire which is harder to work with but better for heat dissipation. The site for the charger is on a concrete block wall and John went extra miles to make sure the charger was attached to the concrete nice and strong. For such a beautiful job, John's price is very reasonable.
John did a great job in getting recessed lights in my home and put in extra one too. His price was very reasonable and got it done quickly as well. I would highly recommend him.
Was available the morning I called. Figured out how to fix the problem. Had to make an unexpected trip to Tags and also cut a part down to size. He's great.
