McMillian Electrical Services

McMillian Electrical Services is John McMillian's one-person electrical shop in Cambridge, and after 16 years on his own he's built something rare: a completely clean record. Across 21 ratings on both Angi and HomeAdvisor, the average sits at a flat 5.0 — every single review lands at the top. The specifics, when reviewers give them, describe ordinary household electrical work done carefully. In an early-2026 review, a customer described him wiring a Tesla wall charger and choosing heavier metal-clad cable over the lighter wire another electrician had suggested, because it handled heat better. A cluster of reviews from 2025 describe a service upgrade from 100 to 200 amps done alongside new outlets and a hardwired picture light, a garage rewiring paired with new LED fixtures, and a tracked-down fix to outdoor lighting that had stopped working. One 2025 reviewer called him in specifically to handle repairs ahead of putting a house on the market. What repeats across nearly every review isn't the size of the job but how he runs it: he comes out to look before quoting, sticks to the number he gives, shows up when he says he will, and leaves the work area clean when he's done — one 2025 reviewer specifically noted he cleaned up even after a neighborhood power outage interrupted the job midway through. Several describe him as more affordable than larger outfits "with the fancy trucks and radio ads," and more than one reviewer mentions calling him back for repeat work or recommending him to friends and family. There's little to flag. No review drops below five stars, and there's no lapsed license or negative press to weigh against the praise — the one sour note in the record, a 2026 customer grumbling about Angi's own AI assistant wasting their time, has nothing to do with McMillian's own work. Angi and HomeAdvisor both list a Massachusetts trade license (#13678, expiring July 2028) for the business, though that's the directories' own record rather than a state verification, and HomeAdvisor's listing appears to mirror Angi's data rather than an independent count. For a smaller residential electrical job — a panel upgrade, an EV charger, a stubborn light or outlet — this looks like a safe, well-reviewed call. Since McMillian appears to run the business alone, it's worth confirming his current availability directly before booking.
