C.M. Joy Company - Kingston Electrical and HVAC

Eversource drove past a Kingston remodel after a big snowstorm and tore the electrical service clean off the house. The contractor called Chris Joy on a Sunday; he was on site inside an hour and had the client's power back. He works much the same way on ordinary days — showing up when he says he will, and finishing neatly enough that other tradespeople notice. C.M. Joy is a veteran-owned, locally owned electrical and heating-and-cooling company based in Kingston, covering the South Shore and Boston-area towns it lists: Duxbury, Hanover, Hingham, Norwell, Pembroke, Plymouth, Quincy, Scituate, Cohasset, Cambridge and Boston. Chris Joy is on the jobs himself with a small crew, which is why nearly every review names him personally. Electrical and ductless heating often land in the same visit. In May 2026 one homeowner had underground power run to the house and the overhead wires taken down, with the new service equipment set neatly and room left for a generator later. Another had old unpermitted wiring pulled out of an apartment building, everything brought up to code, and new heat pumps installed on the same job — his subcontractors told him they had never seen work done that well. A five-zone mini-split with a service upgrade, a Generac standby system, an EV charger that turned into track lighting for an art studio, hardwired smoke alarms, recessed lighting across two properties: most of it done this spring. The trade vouches for him, which is unusual. A working electrician says he refers Chris the jobs he cannot take. A contractor says Chris is the only electrician he trusts for his clients, from high-end projects down to small service work. A carpenter of 55 years, surprised to find him on site before the agreed start time, called him one of the best he has been around. In a July 2024 review, a homeowner who had a three-zone mini-split and a ducted heat pump fitted noted the state program's representative remarked on the install and that the unit was sized correctly. If you want one company handling the panel and the mini-splits together on the South Shore, this is a strong call — and reviewers repeatedly say the final bill matched the quote. Pin the start date down in writing alongside that price, since the same crew is running both trades on every job.
