Pro-Fast Sheet Metal and Ductwork LLC Northborough MA

Every written word about Pro-Fast Sheet Metal and Ductwork was posted in 2026. The shop has been running since June 2020 out of 444 Green Street in Northborough, and its Google page went from nothing to six five-star ratings between January and August of this year. What those reviews describe is specific enough to be useful. One customer had an air conditioning system replaced and singled out the crew for keeping the house clean through the installation. Another had a new HVAC zone and custom ductwork added to a finished basement: "Clean work, fair pricing and our basement has never felt more comfortable." Speed keeps coming up — quotes turned around quickly, crews arriving when they said they would. The permit record backs the trade up. Building permits over the past three years cover a $22,500 two-zone furnace and coil install in North Dighton in September 2025, a $12,000 heat-pump addition with a kitchen exhaust in Hingham in May 2025, and a bathroom exhaust replacement in Brookline that September — small residential mechanical work spread across eastern Massachusetts rather than clustered near home. Its Massachusetts sheet metal business licence, 856-SM-B, is active on the state registry. A business-services firm posted in September 2025 that it had stopped by a five-unit project in Medford where the Pro-Fast team handled all the HVAC work — the only outside account of the work beyond the reviews. Two things to weigh. The written history is young: six reviews, all inside seven months, all five stars, and one of them reads as a well-wisher proud of the owner's business rather than a customer describing a transaction. And a 2023 ductwork and insulation permit in Stow still shows as expired, worth a question if permit close-out matters on your job. For a ducted AC swap, an added zone, or custom sheet metal in a finished space, they are a reasonable call. Ask for two references from jobs like yours, and settle who pulls and closes the permit before work starts.
