Massachusetts refrigeration licenses (Apprentice, Technician, Contractor) are issued under MGL c.146 and 528 CMR 11.00 by the Board of Pipefitters and Refrigeration Technicians within the Division of Occupational Licensure. Continuing education for renewal must be completed through Bureau-approved providers recognized by the Office of Public Safety and Inspections. 528 CMR 11.03 as searched sets prerequisite coursework for initial licensure rather than a numeric renewal-CE rule; verify the current CE-hour requirement and renewal fee on the active Mass.gov refrigeration-renewal page before filing. Gas-fired heating and hydronic work are licensed separately under MGL c.142 and 248 CMR by the Board of State Examiners of Plumbers and Gas Fitters, each with its own CE track.
