Keno Electrical Systems is an electrical company that describes 25+ years of experience across residential, commercial, service repairs, new construction, fire alarm systems, security camera installation and television installation. Its stated service area runs from Hartford and Manchester to Bridgeport, Stamford and Greenwich. On Google it holds 5 stars from 81 ratings. A recent customer called about a broken switch that was starting to spark and melt, and said an electrician was sent right away; the team showed them the damage, explained their options and took their shoes off indoors. A recent customer said Keno resolved an electrical issue the same day, at a price more reasonable than most electricians they called. A 2025 customer said Keno replaced the corroded electrical panel on their new home and sealed the area where water had been leaking into the old panel. A 2025 reviewer wrote that Keno replaced their entire electrical panel and spoke to Eversource after finding that part of the problem came from the main line outside the home. A 2024 customer said Keno updated the electrical panel in their home and reran the cables through the studs so the basement could have a clean finish. A 2025 customer said Keno walked them through a fix over the phone at no charge, after an issue knocked out a bathroom, part of the garage and an outdoor outlet. A 2023 customer said Keno came out the same day when their garage had no power, and that Keno and his guys dug, ran pipe and replaced the underground wires.
