How much do hvac technicians make in Illinois in 2026?

The median HVAC technician in Illinois earns $77,410 per year, which works out to roughly $37.22 per hour based on a standard 2,080-hour work year. That number comes from BLS Occupational Employment and Wage Statistics (OEWS) data released May 2025, covering a broad sample of workers across the state.

The spread between the bottom and top of the pay range is wide. Technicians at the 25th percentile — typically those with fewer years on the tools or working in lower-paying markets — bring home $60,200 annually, or about $28.94 per hour. Workers at the 75th percentile earn $96,030 per year, roughly $46.17 per hour. That $35,000 gap between the 25th and 75th percentile reflects how much experience, specialization, and geography move the needle in this trade.

Where you work in Illinois matters considerably. The Chicago metro — including the collar counties like DuPage, Lake, and Will — tends to carry higher wages than downstate markets in Peoria, Rockford, or the Quad Cities. Commercial and industrial HVAC work in dense urban areas typically pays more than residential service work in smaller cities, because the systems are more complex and the employer pools are more competitive. If you're weighing a job offer or considering relocating within the state, the regional difference can easily be $5,000 to $10,000 per year even within the BLS state average.

Experience is the most direct path to moving from the 25th to the 75th percentile. Entry-level techs handling residential service calls are filling that lower band. Journeyman-level techs who can commission commercial rooftop units, diagnose chiller systems, or handle building automation controls are pulling the numbers closer to $96,000. Specializations in refrigeration, industrial process cooling, or controls and HVAC/R systems integration push even further.

Overtime is a real income driver in HVAC work. Illinois winters push heating calls hard from November through February, and summer cooling season runs hot from June through August. Techs who are available for on-call emergency service can add meaningful hours above their base schedule. Overtime hours billed at 1.5x the standard rate can push annual take-home well above what the BLS percentiles show, since OEWS figures capture base wages and don't fully reflect all overtime earnings.

Illinois does not require a statewide HVAC license, but the EPA 608 certification is federally required for anyone working with refrigerants. Chicago and some other municipalities have their own local licensing requirements, so check the requirements in the specific city or county where you'll be working. Holding EPA 608 Universal certification — which covers all refrigerant categories — rather than just Type I or Type II signals to employers that you can handle larger commercial equipment and is worth negotiating over at hiring time.

Some HVAC technicians in Illinois work under collective bargaining agreements. If you're working under a union contract, your wage scale, overtime rules, and benefits will be set by that agreement rather than by individual negotiation. Check your local's current collective bargaining agreement directly for the applicable wage tables — the figures on this page reflect the full workforce and cannot be mapped to any specific contract.

Apprenticeship is the most structured path into the trade for those starting out. Apprenticeship programs typically run four to five years and combine on-the-job training with classroom hours covering refrigeration theory, electrical systems, and code compliance. Pay steps within an apprenticeship progress annually, and completion generally places a technician at or above the median wage. If you're already working as a tech and looking to increase your earnings, adding controls and building automation skills — or moving toward a service manager or project superintendent role — are the clearest steps to the upper percentiles and beyond.
