BLS metro-level wage data places Heating, Air Conditioning, and Refrigeration Mechanics and Installers pay in Maryland nonmetropolitan area at a median of $59,550 per year ($28.63/hr/hour), drawn from the OEWS May 2025 release for this Metropolitan Statistical Area. Compared to the national median of $61,010, Maryland nonmetropolitan area pays 2% below, which typically tracks with a lower local cost of living or smaller specialized-employer cluster. Approximately 320 heating, air conditioning, and refrigeration mechanics and installerss are employed across the Maryland nonmetropolitan area MSA in SOC 49-9021.

The Maryland nonmetropolitan area pay distribution spans from $44,010 at the 10th percentile to $76,970 at the 90th — a 1.7× 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 $45,450 and the 75th at $66,200, so half of Maryland 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 Maryland 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 MD data, and peer-metro comparisons — a median is a starting point, not a ceiling.
