Commercial HVAC Jobs in Illinois

Illinois has a consistent demand for commercial HVAC technicians across its office buildings, healthcare facilities, and industrial properties. Commercial HVAC technicians work on large-scale systems — rooftop units, chillers, air handlers, and cooling towers in office buildings, hospitals, and industrial facilities. Employers in this market generally require EPA 608 Universal certification and look for hands-on experience with rooftop package units, variable air volume systems, and building automation integration.

Commercial HVAC technicians in Illinois can expect salary ranges that reflect system complexity — entry-level commercial techs typically start above the residential median, and experienced controls or chiller technicians often command rates well above market average. NATE commercial certification and manufacturer-specific training from Carrier, Trane, or Daikin are frequently listed as preferred qualifications by larger service contractors in this market.
