Illinois HVAC Labor Costs — Verified from BLS OEWS (2025)

Every figure on this page is a published U.S. Bureau of Labor Statistics value. Last verified 2026-07-01.

In Illinois, heating, air conditioning & refrigeration mechanics & installers — the core trade for hvac work — earn a mean wage of $37.29/hr ($77,570 per year) in the 2025 BLS OEWS release. That is 20% above the national average (national mean $64,780 per year). Illinois employs about 9,740 heating, air conditioning & refrigeration mechanics & installers statewide. Related trades that price into a typical hvac job include first-line supervisors of construction trades ($103,450/yr). Because labor is the largest variable cost on most hvac projects, these published state wage levels are the biggest single reason hvac costs differ between Illinois and other states. Every figure here is a mean value published by the U.S. Bureau of Labor Statistics and is refreshed automatically when BLS releases new OEWS data.

Across the trades that touch a typical hvac job in Illinois, BLS reports mean wages of heating, air conditioning & refrigeration mechanics & installers at $77,570 per year ($37.29/hr); first-line supervisors of construction trades at $103,450 per year ($49.74/hr). The spread between first-line supervisors of construction trades ($103,450) and heating, air conditioning & refrigeration mechanics & installers ($77,570) reflects differences in skill, certification, and supervisory responsibility on Illinois job sites, and it is why a detailed, line-item estimate beats a single blended rate when you are budgeting hvac work.

Half of Illinois heating, air conditioning & refrigeration mechanics & installers earn less than the median of $77,410 per year — below the $77,570 mean, which a smaller number of higher earners pulls upward. For budgeting, the median is often the more realistic figure for routine hvac crews. BLS counts roughly 9,740 heating, air conditioning & refrigeration mechanics & installers, 19,340 first-line supervisors of construction trades employed across Illinois, a measure of how deep the local hvac-trade labor pool is and how much competition for crews you can expect when scheduling work.

When you budget a hvac job in Illinois, treat these BLS wage levels as the labor-rate floor: a crew's billed rate adds overhead, insurance, equipment, and margin on top of the $37.29/hr mean wage shown above. Because Illinois's heating, air conditioning & refrigeration mechanics & installers wages sit 20% above the national average, a hvac quote that comes in far below these published rates is worth a second look — labor that cheap usually signals a different scope, materials, or crew experience. Use the calculator on this page to combine these Illinois labor rates with your project's material quantities for a complete estimate.
