Thermal Circuits Inc

Thermal Circuits Inc, on Technology Way in Salem, isn't a furnace-and-AC outfit that shows up at a house — it's an industrial manufacturer. Public business records put its start around 1984 to 1985, and today it makes etched foil heaters, heater assemblies, surface and air heaters, and infrared panel emitters for industrial and commercial customers. Its own website says so directly: it is not a home-services trade contractor. It carries a Better Business Bureau A+ grade, though it isn't a BBB-Accredited Business, and shows 3.7 stars across 33 Google ratings. Neither number says anything about home HVAC work, because the company states plainly it isn't in that business — there's no track record of house calls to point to here. One blemish worth flagging: Massachusetts environmental regulators fined the company $18,290 in 2007 for an environmental violation. It's an old mark and unrelated to any home-service question, but it's the one concrete negative on file. On the other side, the company holds ISO 9001:2015 and ISO 13485:2016 manufacturing certifications. For anyone comparing HVAC contractors for a house, this listing is a dead end: there's no evidence here of residential installs, repairs, or service calls, just a heater-component manufacturer that shares the industry's vocabulary. Anyone who landed here hunting for a furnace or AC fix should keep looking elsewhere.
