Keyes North Atlantic, Inc.

Keyes North Atlantic is a Newton-based, family-run design-build contractor whose strongest fit is heating and cooling work. The company says it has served Greater Boston since 1953, with Susan Keyes as President and CEO; its offerings also include electrical, alarm and fire-alarm work. Its Massachusetts HVAC license 250-SM-B is active. The clearest recent example is a July 2026 replacement of a failed heat-and-AC system, which one homeowner said was quick and reasonably priced. A May 2026 reviewer praised efficient work and communication. Earlier customers describe a difficult basement HVAC installation and, in November 2024, a heat-pump installation paired with electrical upgrades. Google shows 3.6 stars from 17 ratings; the available written reviews run from 2023 through 2026 and include both strong praise and specific complaints. The complaints merit a direct conversation. In August 2024, a reviewer objected to a $218 first half-hour charge, $145 hourly billing afterward, and being billed for two hours on a roughly 30-minute job. An October 2023 review described a wrong-size filter taped into place, three appointment reschedules, a refrigerant overcharge and a misdiagnosis. Those are dated accounts, but they are specific enough to ask how labor is billed, how installations are checked and who handles callbacks. Keyes looks suited to homeowners comparing heat-pump or air-conditioning replacement alongside electrical upgrades.
