C.M. Joy Company - Kingston Electrical and HVAC

The number that stands out for C.M. Joy Company is the flatness of it: 74 Google ratings, every one five stars, and zero negative reviews anywhere in the past six months. Chris Joy runs the Kingston-based electrical and HVAC outfit, working jobs across the South Shore. The work behind that record ranges from small fixes to full commercial jobs. He rewired an apartment building's unpermitted electrical and brought it up to code cleanly enough that the building's own subcontractors said they'd never seen it done so well. When Eversource tore an electrical service off a Kingston house mid-remodel, he was on-site within an hour of a Sunday call, after a snowstorm. He's wired overhead doors and coordinated smoke curtain systems on a construction project, put in a Generac standby generator, added an EV charger that turned into a track-lighting install for an art studio, run power to a backyard "she shed," and handled the fixture-level calls — thermostat wiring, a bathroom fan where there wasn't one, four hardwired smoke alarms — that homeowners tend to call an electrician for one at a time. On the HVAC side, multi-zone ductless mini-splits and heat pump installs come up again and again, including one job a customer called "incredibly unique" for how the house was built. Some of the more convincing reviews come from people in the trades themselves: a working electrician who refers overflow jobs to him, a general contractor who says Chris is the only electrician he trusts with his own clients' installs, and a business owner who has subcontracted him for 20 years. Several homeowners describe relationships stretching 15 years or more — an unusual thread for a small shop, and a sign the five-star pattern isn't just new-customer goodwill. There isn't much to caution against. Across 68 reviews spanning 2024 through 2026 on four different platforms, nothing negative turns up — no complaints about pricing, scheduling, or follow-through. The one practical thing worth asking about upfront is how soon he can get to a new job, since a lot of the work clearly comes from repeat clients and referrals rather than first-time calls. For anything electrical or HVAC in the Kingston/South Shore area — a panel upgrade, a generator hookup, a full mini-split changeout — this reads like a contractor worth calling directly, sometimes alongside his apprentice Shay on bigger jobs. Still worth pinning down a specific quote and timeline for your particular job before booking.
