Boston's industrial refrigeration work sits on the water. Seafood processing and cold storage cluster in East Boston, Chelsea, and around the New England Produce Center, which means fish houses and freezer docks rather than the supermarket rack circuit that carries most metros. Massachusetts averages roughly $77,000 a year for refrigeration technicians, and unlike most states, it licenses refrigeration techs directly through the Division of Professional Licensure.
Large-scale freezer warehousing with industrial engine rooms and round-the-clock coverage.
The other major third-party freezer operator, staffing techs on rotating shifts.
Foodservice distribution with cooler and freezer dock refrigeration plus reefer fleet support.
Chelsea produce market operators running cooler space that has to hold through early-morning trading.
Chelsea and Everett are effectively part of the same cold-storage corridor, and Quincy, Worcester, and Brockton pull from the same tech labor pool. A Boston-based service route usually covers all of it.
Massachusetts is one of the states that licenses refrigeration technicians at the state level, through the Division of Professional Licensure, so a card from a neighboring state does not automatically travel. That's on top of EPA 608 certification, which is federal and required anywhere you touch refrigerant. Confirm the current class and scope you need in the state license requirements guide before you accept an offer.
The statewide $77,000 average puts Massachusetts above the national median, and the seafood and cold storage side of Boston skews higher than commercial service because the work is industrial. If you're coming in without field time, the realistic entry is a helper or maintenance-tech opening at a freezer warehouse, then license and credential from inside the job. That path is laid out in the guide to becoming a commercial refrigeration technician.
The Massachusetts statewide average is $77,000 a year, above the national median. Boston's industrial cold storage and seafood processing roles generally sit at the higher end of that, and shift differential on nights adds to it. Compare against other specialties in the 2026 highest-paying rankings.
Both. EPA 608 is federal and non-negotiable for refrigerant work. Massachusetts also licenses refrigeration technicians through the Division of Professional Licensure, which means Boston has a harder credential gate than states that leave licensing to cities or skip it entirely.
Mostly industrial. Freezer warehouses in Chelsea and East Boston, seafood processing on the waterfront, and produce cooler space at the New England Produce Center. Supermarket rack work exists but is a smaller share of the metro than it is in most cities this size.
