BLS metro-level wage data places Heating, Air Conditioning, and Refrigeration Mechanics and Installers pay in Massachusetts nonmetropolitan area at a median of $72,760 per year ($34.98/hr/hour), drawn from the OEWS May 2025 release for this Metropolitan Statistical Area. Compared to the national median of $61,010, Massachusetts nonmetropolitan area pays +19% above, signaling either concentrated employer demand, a cost-of-living premium, or both. Approximately 150 heating, air conditioning, and refrigeration mechanics and installerss are employed across the Massachusetts nonmetropolitan area MSA in SOC 49-9021.

The Massachusetts nonmetropolitan area pay distribution spans from $51,860 at the 10th percentile to $102,610 at the 90th — a 2.0× spread that reflects experience tenure, specialization, employer size, and the difference between public-sector, nonprofit, and private-sector compensation inside the metro. The 25th percentile sits at $60,170 and the 75th at $86,080, so half of Massachusetts nonmetropolitan area-based heating, air conditioning, and refrigeration mechanics and installerss earn within that middle band.

Metro figures capture where you actually work, not just where you live — which matters for commuters. BLS draws metro boundaries from the OMB MSA definitions, so Massachusetts nonmetropolitan area covers the central city plus outlying counties tied to the metro economically. Remember that OEWS wages reflect base pay only: employer-provided health insurance, retirement matches, stock options, signing bonuses, overtime, and tips are excluded and can add 20-40% to real total compensation. Before using this metro median as a negotiation anchor, triangulate against the same occupation's national profile (linked below), its state-wide MA data, and peer-metro comparisons — a median is a starting point, not a ceiling.
