1. Massachusetts HVAC Licensing — Sheet Metal and Gas Fitting

   Massachusetts has no combined HVAC contractor license and no pipefitter license category. Ductwork and sheet metal installation is regulated by the Board of Examiners of Sheet Metal Workers, under the Division of Occupational Licensure, which licenses apprentice, journeyperson, and master sheet metal workers — and licenses the business itself: every corporation, partnership, LLC, or LLP performing sheet metal work in Massachusetts must hold a Sheet Metal Business License. The entity must be chartered with the Secretary of the Commonwealth (or registered as a foreign corporation), every partner in a partnership or LLP must hold a current Master Sheet Metal Worker license, a corporation must have at least one Master as a corporate officer, and an LLC must designate a Master as its Manager and Responsible Craftsman. Gas-fired equipment work is separate and requires a gas fitter license from the Board of State Examiners of Plumbers and Gas Fitters; a licensed master or journeyman plumber may also perform gas fitting work.

1. City of Boston — Mechanical (HVAC) Permits

   HVAC work in Boston is permitted through the Inspectional Services Department, with separate permits by trade: a sheet metal permit for ductwork, a gas permit for gas-fired equipment, and electrical and plumbing permits where applicable. Permits must be pulled by the appropriately licensed trade person — sheet metal, gas fitting, electrical and plumbing licenses are issued by the state Division of Occupational Licensure boards, not by the city. Each permit is inspected and must be finalized by the building inspector before a Certificate of Use and Occupancy will issue.
