John A Penney & Co

Fifty-plus years is the headline here: the company says it has run continuously out of Cambridge since 1973, under its prior ownership since 1988, as an electrical engineering and construction firm rather than a service call for a flickering outlet. Its own history points to commercial, institutional, life-science, and tenant fit-out work across Greater Boston, backed by real trade credentials — it's a signatory IBEW Local 103 contractor and a NECA member. The public customer trail is thin, though. Google shows a 4.2-star average, but from only 5 ratings, too few to lean on with any confidence, and the Better Business Bureau lists an A+ grade with no posted reviews and no complaint count on the profile. That BBB page also notes the business itself has never pursued BBB accreditation, despite the grade. Two things are worth confirming before calling: the company recently became a division of Sullivan & McLaughlin (SullyMac), which the site says won't disrupt current projects or teams, but it's fair to ask who on the ground will actually run a new job. And because everything on record describes large commercial and institutional electrical work, it's worth asking directly whether routine residential service is still something they take on. This reads like an established commercial electrical contractor with genuine industry credentials rather than a residential specialist with a deep public reputation — a reasonable call for a larger or commercial-scale project, provided the post-acquisition team and residential availability get confirmed first.
