HVAC Apprenticeships in Illinois: Programs, Requirements and How to Apply

Founder, HVACHires
Last verified September 2026

Illinois has no state apprenticeship agency and no state HVAC license to work under: it is a federal Office of Apprenticeship state, so the U.S. Department of Labor registers Illinois apprenticeship programs, and you apply with the sponsor itself.

The program the research verified is on the plumbing side — Chicago's UA Local 130 runs a five-year Joint Apprenticeship Committee apprenticeship.

Refrigerant work brings the federal EPA 608 certification rule, with an exemption for supervised apprentices.

Verify before you rely on this

Licensing rules change by statute, board rule and local ordinance, and this page is career information, not legal advice. Confirm every requirement with the licensing board (or, where licensing is local, the city or county) before you apply, schedule an exam, count hours or bid a job. In Illinois, that is the U.S. Department of Labor, Office of Apprenticeship.

At a glance

Apprenticeship agency

None at the state level.

Illinois is a federal Office of Apprenticeship state: the U.S. Department of Labor registers Illinois apprenticeship programs.

Apprentice registration

No state HVAC license to hold — Illinois licenses no HVAC trade statewide, so there is no state HVAC apprentice registration either.

Illinois does require an apprentice license on the plumbing side: an IDPH apprentice plumber license.

Union programs

The program the research verified is Chicago plumbers' UA Local 130: a five-year Joint Apprenticeship Committee apprenticeship.

No HVAC-specific Illinois UA program was confirmed.

Merit-shop programs

Not established in our research for Illinois — registered programs of the PHCC, ABC and ACCA chapters were not verified, so ask the chapter.

Hours toward a license

No state HVAC license exists to credit hours toward.

Federal floors apply: at least 2,000 hours of on-the-job learning, and 144 classroom hours a year recommended, not required.

Where to start

Apply directly with a program sponsor — a union training committee, an association chapter or an employer-based program — and confirm the program's registration with the U.S. Department of Labor.

Who offers HVAC apprenticeships in Illinois?

Illinois is a federal Office of Apprenticeship state: registered apprenticeship programs there are registered by the U.S. Department of Labor, not by a state apprenticeship agency.

Nationally, that registration runs either through the Office of Apprenticeship, which registers programs in states with no recognized state apprenticeship agency through its state field offices, or through a recognized state agency acting for the department; Illinois sits on the federal side of that split.

Sponsors range from union training committees — the United Association says its registered apprenticeships cover plumbing, pipefitting, HVACR, welding and fire protection — to the association and employer-based programs covered under merit shop below.

In Illinois, the program our research verified is Chicago Journeymen Plumbers' and Technical Engineers Local Union 130 UA's Joint Apprenticeship Committee apprenticeship, which trains plumbers.

Our research did not confirm the details of an HVAC-specific registered program in Illinois, and it did not survey downstate markets — Peoria included — so ask sponsors directly and check any program's registration with the department.

Do Illinois apprentices need to register or hold a license?

📜 225 ILCS 320; 40 CFR 82.161

Illinois has no statewide HVAC technician or HVAC contractor license: the Illinois Department of Financial and Professional Regulation's list of regulated professions includes no HVAC, heating, mechanical or refrigeration entry, and where HVAC licensing exists it is set by individual municipalities.

So there is no state HVAC license for an apprentice to hold and no state HVAC board to register with.

The apprentice license requirement Illinois does set sits on the plumbing side: plumbing apprentices must hold an IDPH apprentice plumber license, a sponsor that ends sponsorship must notify IDPH within 15 days, and an approved apprenticeship program may not sponsor more licensed apprentices than 2 times the number of licensed plumbers available to supervise them.

There is no analogous state rule for HVAC apprentices.

In Chicago, mechanical (HVAC) permits list the required contractor as a licensed general contractor, Class A, B, C, D or E depending on total project cost, and the city's trade licenses cover drain layer, electrical, elevator, mason and plumbing — not HVAC.

The federal layer applies in every state: work that could breach a refrigerant circuit requires EPA 608 certification, and apprentices are exempt only while closely and continually supervised by a certified technician.

“Apprentices are exempt from the requirement in paragraph (a)(1) of this section provided the apprentice is closely and continually supervised by a certified technician”

Union programs and locals: UA Local 130 and HVACR training

The United Association says its apprenticeships are registered with the U.S. Department of Labor, typically last five years, and cover plumbing, pipefitting, HVACR, welding and fire protection.

The Illinois union program our research verified is Chicago Journeymen Plumbers' and Technical Engineers Local Union 130 UA's Joint Apprenticeship Committee (JAC) apprenticeship: it lasts five years, with four days on the job and one day of class per week in years 1 through 3, and its site is plumberslu130ua.com.

It trains plumbers, not HVAC technicians.

Our research did not confirm an HVAC-specific registered program at an Illinois UA local, so ask the local you are considering which trades it is currently registering, and confirm any program you are offered against the department's registration.

“The length of the Apprenticeship program is five (5) years.”

Merit-shop and employer programs in Illinois

For the merit-shop side, our research did not verify registered HVAC programs run by Illinois chapters of the national associations, so treat them as places to ask rather than options we have confirmed.

ABC describes itself as founded on the merit shop philosophy and reports more than 24,000 members, though which chapters run HVAC programs is chapter-level detail the research did not verify.

PHCC offers apprenticeship content through its online learning academy, and its Educational Foundation is an EPA-approved 608 certifying program; chapter-level registered apprenticeship availability and tuition were not verified either.

ACCA reports 60,000 professionals and more than 3,000 company members and is an EPA-approved 608 certifying program, but our research found no ACCA registered apprenticeship — a gap in the research, not a verified negative.

Employer-based programs sit on this side of the split as well, and whatever the sponsor, registration runs through the Office of Apprenticeship rather than a state agency.

Ask the Illinois chapter of whichever association you approach, and confirm any program's registration with the U.S. Department of Labor.

Schools and related-instruction providers in Illinois

Registered apprenticeship combines on-the-job learning with related technical instruction, and programs structure the classroom side differently: terms may be time-based (at least 2,000 hours of on-the-job learning), competency-based, or a hybrid of both.

The Department of Labor recommends a minimum of 144 hours of related technical instruction per year of apprenticeship — a recommendation, not a federal requirement.

Because Illinois sets no state HVAC license, there is no state table that credits school hours toward a credential; the licensing detail is the Illinois HVAC license page's to own.

Our research did not survey Illinois schools and community colleges as HVAC related-instruction providers, so we cannot name one.

For what related instruction looks like in the program we did verify: Local 130's apprentices spend one day a week in class during years 1 through 3.

Ask each sponsor where its classroom hours are delivered, and confirm the arrangement with the school.

How to apply for an HVAC apprenticeship in Illinois

There is no state application: registered programs in Illinois are registered by the U.S. Department of Labor's Office of Apprenticeship, so you apply to the sponsor itself — a union training committee such as Local 130's JAC, an association chapter, or an employer-based program — and ask it to confirm the program's federal registration.

Expect the federal floor: registered apprentices must be at least 16 years old unless a higher minimum age is set by law; there is no federal maximum age, and federal rules bar discrimination against apprentices and applicants aged 40 or older, though individual sponsors may set their own qualifications on top.

An apprenticeable occupation requires at least 2,000 hours of on-the-job learning, and a probationary period may not exceed 25 percent of the program length or 1 year, whichever is shorter.

Pay follows a progressively increasing schedule tied to skill, with the entry wage not below the FLSA minimum where it applies and no federal percentage steps — each program's standards set its own.

Completion earns a certificate from the registration agency; it is not a license.

Frequently Asked Questions

Do you need a license to be an HVAC apprentice in Illinois?

No. Illinois issues no statewide HVAC license of any kind — the state's list of regulated professions has no HVAC, heating, mechanical or refrigeration entry — so there is no license or state registration for an HVAC apprentice to hold.

Illinois does license plumbing apprentices at the state level — they hold an IDPH apprentice plumber license — but there is no HVAC equivalent.

What does reach HVAC apprentices is federal: refrigerant work requires EPA 608 certification, and apprentices are exempt only while closely and continually supervised by a certified technician.

How long is an HVAC apprenticeship in Illinois?

Federal rules set the floor: an apprenticeable occupation requires at least 2,000 hours of on-the-job learning, and United Association programs typically last five years.

The Illinois program our research verified — Chicago plumbers' UA Local 130's Joint Apprenticeship Committee apprenticeship — spans five years.

We did not confirm a term for an HVAC-specific Illinois program, so ask each sponsor for its length and how it splits job hours and classroom hours.

How much do HVAC apprentices get paid in Illinois?

Registered programs must pay a progressively increasing wage schedule tied to skill, and the entry wage may not fall below the FLSA minimum wage where it applies; the federal rule sets no percentage steps, so each program's standards set its own scale.

Our research has no verified Illinois apprentice wage figures, so ask each sponsor for its current schedule.

For pay context, see our HVAC apprentice pay guide.

Is there a union HVAC apprenticeship in Chicago?

The union program the research verified in Illinois is Chicago's UA Local 130 Joint Apprenticeship Committee plumbing apprenticeship, which runs five years with four days on the job and one day of class per week in years 1 through 3.

It trains plumbers; the United Association's registered apprenticeships nationally cover HVACR as well, but we did not confirm an HVAC-specific program at an Illinois local.

Ask Local 130 or the UA local near you what it currently registers, and confirm the program's registration with the Department of Labor.

Does an HVAC apprenticeship count toward an Illinois license?

There is no statewide Illinois HVAC license to count toward — licensing, where it exists, is set by individual municipalities — so check with the building or licensing department where you will work.

Completing a registered apprenticeship does earn a completion certificate from the registration agency, but that certificate is not a trade license.

If you later cross into plumbing, Illinois licenses plumbing apprentices separately through IDPH.
