BLS metro-level wage data places Heating, Air Conditioning, and Refrigeration Mechanics and Installers pay in Sioux City, IA-NE-SD at a median of $59,840 per year ($28.77/hr/hour), drawn from the OEWS May 2025 release for this Metropolitan Statistical Area. Compared to the national median of $61,010, Sioux City pays 2% below, which typically tracks with a lower local cost of living or smaller specialized-employer cluster.

The Sioux City pay distribution spans from $39,330 at the 10th percentile to $81,880 at the 90th — a 2.1× spread that reflects experience tenure, specialization, employer size, and the difference between public-sector, nonprofit, and private-sector compensation inside the metro.

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 Sioux City, IA-NE-SD 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 IA data, and peer-metro comparisons — a median is a starting point, not a ceiling.
