HVAC Technician Salary in Illinois: Pay by Experience, City & Take-Home

An HVAC technician in Illinois earns a median of $77,410 a year, or about $37.21 an hour, according to the U.S. Bureau of Labor Statistics (2025). Most of the field lands between $46,690 at the 10th percentile and $117,550 at the 90th. That median sits well above the national HVAC median of $61,010, so Illinois is one of the stronger states in the country for this trade.

How Illinois compares to the national average

Start with the gap, because it’s large. The national median for HVAC technicians is $61,010, per the BLS. Illinois pays a median of $77,410. That’s $16,400 more a year, or roughly 27 percent above the typical American HVAC paycheck. For a trade where the same EPA Section 608 certification and the same equipment apply nationwide, that’s a meaningful premium for working in Illinois.

The Illinois mean wage, $77,570, sits almost exactly on top of the median, which tells you the state’s pay is fairly balanced rather than dragged up by a handful of high earners. The spread still matters though. The 10th percentile is $46,690 and the 90th is $117,550, so the gap between a new tech and a seasoned one in Illinois is more than $70,000 a year. Where you fall in that range comes down to experience, certifications, the kind of work you do, and the metro you do it in. The rest of this page breaks each of those down using the BLS numbers.

HVAC technician pay in Illinois by experience

Experience is the single biggest lever on HVAC pay in Illinois, and the BLS percentile data shows it clearly. A first-year tech or helper starts near the bottom of the range while a master tech or service lead with a decade in the field commands close to triple that. Here’s how the percentiles map to career stage.

A new technician in Illinois walking in with an EPA card but little field time should expect something in the $46,690 to $60,200 band. That’s the 10th to 25th percentile, and it’s where helpers, apprentices, and recent trade-school grads sit while they build hands-on hours. The work at this stage leans toward assisting on installs, hauling equipment, and learning to read systems under a lead tech.

The jump to the median, $77,410, usually tracks with three to five years of solid field experience and a real grip on diagnostics. Once you can troubleshoot a refrigeration circuit, commission a system, and handle a service call solo without a callback, you’re earning your way toward that 50th percentile and past it.

The top of the range is where the money gets serious. The 75th percentile is $96,030 and the 90th is $117,550. Techs at this level are typically running commercial or industrial systems, holding specialty certifications, leading crews, or carrying the on-call work that pays a premium. In Illinois the climb from median to senior is worth more than $40,000 a year, which is why the certifications and specialties covered further down matter so much. They’re how you move up the percentile ladder rather than staying parked at the median.

It helps to see the steps as dollars rather than abstract percentiles. Going from the 10th percentile ($46,690) to the 25th ($60,200) is a $13,510 raise, and it’s the fastest jump of all because it mostly comes from logging field hours and earning your EPA card. The next step, 25th to median ($77,410), adds another $17,210 and rewards diagnostic skill. From median to the 75th ($96,030) is $18,620 more, and from there to the 90th ($117,550) is a final $21,520. Each rung up the ladder pays slightly more than the one below it, so the back half of an HVAC career in Illinois compounds faster than the start. That pattern is the opposite of many salaried desk jobs, where raises shrink with seniority, and it’s a strong argument for sticking with the trade long enough to reach the upper percentiles.

HVAC salary by Illinois metro

Where you work inside Illinois changes the number, and not always in the direction people expect. Chicago has the volume, but it isn’t the highest-paying metro in the state. Here are the five largest Illinois metro areas by HVAC employment, with their median pay, from the BLS.

Peoria tops the list at $78,710, edging out Chicago’s $77,960. The difference between the two is small, under $800 a year, but it’s a useful reminder that you don’t have to be in the largest city to earn the strongest median. Peoria’s smaller HVAC workforce, 370 jobs against Chicago’s 7,210, can mean experienced techs are in tighter supply and command top dollar.

Chicago is still the center of gravity for the trade in Illinois. With 7,210 HVAC jobs, the metro holds the vast majority of the state’s 9,740 positions. That depth matters for a job seeker. More employers, more commercial and high-rise work, and more specialization options all live there, and the $77,960 median is right in line with the statewide figure.

Rockford ($75,070) and Champaign-Urbana ($74,880) cluster just below the state median, while Bloomington trails the group at $64,030. Bloomington’s median is more than $14,000 below Peoria’s, so within a single state the metro you choose can swing your pay by a real margin. The catch is that lower-paying metros often come with lower housing costs, which is why the take-home and cost-of-living math in the next section matters more than the gross number alone.

One more thing worth pulling out of the table: employment density. Chicago’s 7,210 jobs make up about 74 percent of the 9,740 HVAC positions in Illinois, which means the other four metros listed here, plus the rest of the state, split the remaining quarter. For a job seeker, that has two practical effects. In Chicago you’ll find the most openings, the most employers competing for skilled techs, and the widest mix of residential, commercial, and high-rise work, which is exactly the kind of variety that builds the resume needed to reach the upper percentiles. In a smaller market like Peoria, Rockford, or Champaign-Urbana, there are fewer postings at any given time, but a strong tech can become hard to replace quickly, and the median pay holds up well. Bloomington is the outlier on pay at $64,030, but with only 140 HVAC jobs it’s also the thinnest market of the five, so a single large employer can shape the local wage. None of these metros pays below the national median of $61,010, which underscores how Illinois lifts HVAC pay across the board rather than only in its biggest city.

Take-home pay after taxes in Illinois

Gross pay isn’t what lands in your account. Illinois levies a flat state income tax on top of federal income tax and FICA, so the number that actually shows up on payday is smaller. Here’s the breakdown at four points across the HVAC range, using the 2026 tax-year estimates in our data.

At the median, an Illinois HVAC tech grossing $77,410 keeps about $59,012 a year, or $4,918 a month, after federal tax, FICA, and the state’s flat income tax. That’s an effective tax rate near 23.8 percent. The entry-level tech at $46,690 keeps $37,243 (a 20.2 percent effective rate), and the senior tech at $117,550 nets $85,264, where the effective rate climbs to 27.5 percent as more income falls into higher federal brackets.

Now the cross-state comparison, because it’s where Illinois costs you. Take the same median HVAC tech earning $77,410. In Illinois the net is $59,012. In Texas, a state with no income tax, the same gross nets $62,844. That’s a gap of $3,832 a year that an Illinois tech hands over to the state that a Texas tech keeps. Over a decade, that’s more than $38,000 in state income tax alone, money a no-tax state never touches.

Notice how the state tax line grows across the range. At entry, Illinois takes $2,311. At the median it’s $3,832, at the 75th percentile $4,753, and at the 90th $5,819. Because Illinois uses a flat rate, the dollar amount rises in step with income while the percentage stays steady, so the state bite is predictable as you climb. The federal number, by contrast, accelerates: it more than doubles from $8,644 at the median to $17,475 at the senior level as more income crosses into higher brackets. That’s why the effective rate moves from 20.2 percent at entry to 27.5 percent at the top. The practical takeaway is that a raise from the median to the 90th percentile, $40,140 in gross, adds about $26,252 to your net annual pay rather than the full gross, because federal brackets and FICA claim the rest. It’s still a large raise. It’s just smaller than the sticker number suggests.

Before you book a U-Haul to Texas, the net pay minus local housing is the number that actually matters. A higher net in a no-tax state gets eaten fast if rent and home prices are higher there, and a lower net in Illinois can stretch further in a metro like Peoria or Rockford where housing is cheap. Compare net take-home against your actual local cost of living, not the gross salary and not another state’s sticker number. Run your own figure through the Illinois paycheck calculator to see exactly what your bracket nets. When tax season comes, filing trade income, tool deductions, and any 1099 side work is easier with software like TurboTax walking you through it.

How to earn more as an HVAC technician in Illinois

The gap between the Illinois median ($77,410) and the 90th percentile ($117,550) is more than $40,000 a year. That spread is real and reachable. Here’s how Illinois techs move up the percentile ladder.

• Add specialty certifications. An EPA Section 608 card is the baseline, but moving into commercial refrigeration, NATE certification, or specialized controls and building-automation work is what separates a median earner from a 75th-percentile tech making $96,030. Structured coursework through platforms like Coursera can shore up the electrical, controls, and HVAC theory that employers pay extra for.
• Move into commercial and industrial work. Residential service is steady, but the largest checks in Illinois come from commercial rooftop units, chillers, and industrial process cooling. These systems are more complex, the stakes are higher, and the pay reflects it. Chicago’s 7,210 HVAC jobs include a deep bench of commercial and high-rise work that smaller metros can’t match.
• Take the on-call and overtime. HVAC is seasonal and emergency-driven. Techs who carry summer and winter on-call rotations or pick up overtime during peak demand routinely earn well above their base, which is part of how the top of the range reaches $117,550.
• Get your license and go independent. Many of the highest earners run their own service business or work as a lead contractor. Illinois regulates HVAC and contractor work, so confirm the current state and local licensing requirements before you make the jump, then price your own jobs rather than collecting an hourly wage.
• Target the right metro. Peoria’s $78,710 median tops Chicago’s, and several Illinois metros sit above $74,000. If you’re geographically flexible, comparing metro medians against local housing costs can net you a real raise without changing employers.
• Build toward a lead or supervisor role. Crew leads, service managers, and project supervisors carry the pay that lands in the 90th percentile. Document your callbacks-free record, mentor junior techs, and make the case for the next title.

Job outlook for HVAC technicians in Illinois

Illinois employs about 9,740 HVAC technicians, per the BLS, and roughly three-quarters of them, 7,210, work in the Chicago metro. That concentration tells you where the hiring depth is. The trade is tied to construction, building maintenance, and equipment replacement cycles, all of which keep demand steady, and the median pay of $77,410 signals a labor market that values the skill.

The structural tailwind for HVAC nationwide is the same one operating in Illinois. Existing systems age and need service, efficiency standards push equipment replacement, and there aren’t enough trained techs entering to fully replace those retiring. For someone weighing the trade, that combination of a high median, a wide path to six figures at the top end, and consistent demand makes Illinois a solid place to build an HVAC career.

Related and higher-paying trades in Illinois

HVAC pays well in Illinois, but two neighboring trades pay even better here. Both the electrician and plumber medians sit above the HVAC median, so if you’re early in your career and weighing trades, the gap is worth knowing.

An electrician in Illinois earns a median of $99,560, which is $22,150 more than an HVAC technician in Illinois. A plumber earns a median of $99,950, or $22,540 more than an HVAC tech in the state. These trades pay close together nationally, but in Illinois the electrical and plumbing medians run a clear step ahead of HVAC. That doesn’t mean switching, many techs cross-train and carry multiple licenses, but it’s useful context for where the trade ladders sit.
