# WINCHESTER MECHANICAL **Trade:** HVAC / Heating & Cooling · **Address:** 20 Trafalgar Sq Suite 109, Nashua, NH 03063 · **Phone:** (603) 402-1934 · **Languages:** English **Rating: not yet scored** — 0 reviews across 5 sources is too little evidence for an honest number. ## The honest read 111 projects on its Procore profile and 44 building permits on BuildZoom: Winchester Mechanical, LLC does the kind of HVAC work that gets pulled as a permit, not squeezed into an afternoon. Its BBB page describes a Nashua, New Hampshire contractor with 36 years of operating history, and the company's own Procore listing gives a service area across New Hampshire and Massachusetts. The BBB service list is a wide one — heating systems, HVAC installations and repairs, custom ductwork, indoor air quality, geothermal and residential geothermal, alongside commercial HVAC installation, building maintenance and design-build. The sheet-metal side of the trade shows up in its licensing too. The BBB lists the company as accredited with an A+ grade, cites a New Hampshire fire-safety licence and gives the number MBE1500883. BuildZoom lists two Massachusetts licences for the company: a sheet metal business licence and master pipefitter licence #PM-028472. This is the shop to call for a geothermal system, a heating replacement or ductwork you want designed rather than patched. Ask which licence covers the work at your address — New Hampshire and Massachusetts keep separate registers — confirm the current status with the state, and get the scope, the equipment and the price in writing before you sign. **Strengths:** - Permit-backed history — 44 BuildZoom permits and 111 Procore projects - A+ BBB grade — accredited HVAC contractor on its BBB page - Geothermal and ductwork — residential geothermal, custom ductwork and air quality listed - 36 years stated — BBB page cites a long operating history **Where sources disagree:** - BuildZoom gives a Burlington, Massachusetts address for the company, while its BBB and Procore profiles both place it in Nashua, New Hampshire. ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. -
