Massachusetts HVAC technician license requirements
The answer
Massachusetts licenses REFRIGERATION work, not 'HVAC' generally: a state refrigeration license is required for installing, repairing, replacing or maintaining any refrigerant-containing part of refrigeration/AC systems of TEN (10) TONS or greater. The ladder is Refrigeration Apprentice ($40) → Refrigeration Technician → Refrigeration Contractor, with exam prerequisites set by 528 CMR 11. Smaller systems need no state refrigeration license — federal EPA 608 still applies.Your paths to the license
Apprentice → Technician → Contractor
Register as a Refrigeration Apprentice ($40; 18+, diploma/equivalent, Division of Apprentice Standards card, employed by a MA Refrigeration Contractor — and note the apprentice license only renews twice), then qualify for the Technician exam under 528 CMR 11, and later the Contractor license.
Under-10-ton work: EPA 608 route
Systems below 10 tons of refrigeration need no Massachusetts refrigeration license — get EPA Section 608 certified (federal law for refrigerant handling) and train on the job. Electrical and gas-fitting portions still trigger those separate MA licenses.
Licensed in another state
No refrigeration reciprocity is published — out-of-state technicians qualify under the 528 CMR 11 prerequisites and take the Massachusetts exam.

Moving here with a license? Renewal? The rest of the picture
Reciprocity: No refrigeration reciprocity published; EPA 608 (federal) transfers everywhere. Check your exact state pair →
Renewal & continuing education: Apprentice licenses may only be renewed twice — progress to Technician within that window. Technician/contractor renewal per Bureau rules.
Federal layer: EPA Section 608 certification is required federally for anyone who maintains, services, repairs or disposes of equipment that could release refrigerants — including all under-10-ton work Massachusetts itself doesn't license.
Watch out: The 10-ton threshold is the load-bearing fact: at or above it you need the state refrigeration license; below it you don't (but EPA 608 always applies). · Technician/contractor exam prerequisites are set by 528 CMR 11 — read the regulation before planning your hours.
