John Teheen Master Electrician LLC

John Teheen Master Electrician LLC, based in Salem, is the electrician homeowners call when a job needs real technical judgment — removing knob-and-tube wiring from an old house, running underground power for a new pool, wiring in a sub-panel to handle multiple sump pumps. Across 54 Google reviews from 2021 through 2026 (4.7★ from 64 ratings), the same names keep coming back — one customer says they've used him for ten years and won't trust anyone else with big jobs. The recurring theme is technical range paired with fast turnaround: a chandelier installed the same afternoon it was requested on New Year's Eve, a fuse switch swapped during a full power outage, hard-wired smoke detectors finished days ahead of a tight closing deadline despite an incoming snowstorm. More than one review describes him catching problems beyond the original ask — ungrounded outlets, a missing kitchen GFCI, a washer and fridge sharing a circuit across floors — while doing separate, planned work. The Better Business Bureau lists the company at an A+ grade. Not every account is glowing. Two 2023 reviews describe real problems: one says a project was left with a light and a switch that didn't work after repeated delays and a dispute over billing for items the customer says were already in the original contract; another, after getting a second opinion, says work wasn't completed as paid for and that some of it wasn't up to code. A separate 2021 review, written from what reads as a former employee's perspective rather than a customer's, describes poor treatment of workers and unreliable scheduling — worth knowing, though it isn't about the quality of work delivered to homeowners. Given how busy the reviews describe him as being, plan ahead rather than expecting a same-day slot for anything but true emergencies — and given the two 2023 complaints, it's reasonable to get scope and price in writing before work starts. For a job that needs real electrical judgment — old-house rewiring, pool and generator hookups, a panel planned for future load — this is a deep record to draw from.
