Forge Mechanical LLC

Forge Mechanical is a Rockland-based HVAC, plumbing and electrical outfit, and the name that comes up again and again in its reviews is Mark — also listed on Thumbtack as Mark Dyszczyk — who shows up personally on calls across the South Shore. The company says its owner spent more than 10 years in the HVAC trade before opening Forge Mechanical on his own, and describes the shop as owner-operated. Across 17 reviews on Google and Thumbtack from 2023 through 2026 — all five stars — the same pattern holds: homeowners call for a heat pump that needs reconnecting, a furnace that won't start, a leaky oil tank, or a stubborn drain, and come away describing a tech who explained the options, didn't try to upsell a new system, and charged what was quoted. In a 2026 review, one customer noted the final bill matched the original estimate with no add-ons; another, also from 2026, described technicians who found mid-installation that new thermostat wiring was needed and ran it properly rather than take a shortcut. A 2023 review described a leaky oil tank replaced quickly with flexible scheduling and a clean job site afterward, and one 2026 reviewer reported three separate service calls in a 90-day span, happy each time. The reviews lean heavily HVAC and plumbing — heat pumps, furnaces, AC, water heaters, drains and fixtures — and the company's own service list also includes electrical service upgrades to support new equipment. For a heat pump, furnace or plumbing call on the South Shore, the reviews point to a company that shows up, explains the diagnosis, and sticks to its quote — confirm current scheduling and whether the same technician is available for your job.
