HVAC apprenticeships in Arkansas are registered with the federal U.S. Department of Labor Office of Apprenticeship: Arkansas is an Office of Apprenticeship state, so you apply to the program sponsor, not a state agency.
There is no separate apprentice license, but the state does license the worker: anyone doing HVACR work must hold a class license or the HVACR registrant card, which costs $25 per year, and a registrant can only work for an HVACR licensee.
The union locals our research verified are UA Local 155 and SMART Local 78 in Little Rock.

The federal U.S. Department of Labor Office of Apprenticeship: Arkansas is an Office of Apprenticeship state, so the federal office registers apprenticeship programs rather than a state agency.
A worker registration, not a separate apprentice license: anyone doing HVACR work must hold an HVACR class license or the registrant card ($25 per year, at least 18), and a registrant can only work for an HVACR licensee.
UA Local 155 covers the State of Arkansas (Little Rock); SMART Sheet Metal Local 78 is listed as Little Rock, Arkansas (office in Sherwood).
Not established in our research for Arkansas: no registered PHCC, ABC or ACCA HVAC program in the state was verified, so ask the chapter or the employer directly.
Our research found no published hour total for HVAC apprentices.
For licensure: a registrant becomes eligible for the class exam after 2 years on the card, or 1 year plus 1 year of technical experience.
Pick a route β UA Local 155, SMART Local 78 or an employer that holds an HVACR class license β apply to the sponsor, and plan on the $25 registrant card once you are working.
Registered apprenticeship in Arkansas sits at the federal level: the U.S. Department of Labor lists Arkansas under its Office of Apprenticeship, so programs are registered by DOL's Office of Apprenticeship, which runs state field offices where no recognized State Apprenticeship Agency exists.
There is no state apprenticeship agency to apply to β you apply to the program sponsor itself.
The sponsors our research confirmed in Arkansas are the union locals below; employer and association programs are covered further down this page.
Nationally, the United Association says its apprenticeships are registered with DOL, typically last five years, and cover plumbing, pipefitting, HVACR, welding and fire protection.
Yes.
Arkansas licenses the individual worker: every individual who designs, installs, services or repairs an HVACR system must hold an HVACR class license or a registration, issued by the HVACR Licensing Board within the Arkansas Department of Labor and Licensing.
A worker who is not a class holder must hold the current HVACR registration β the registrant card β and can only perform work for an HVACR licensee.
The registrant fee is $25 per year, and registrants and class-license applicants must be at least 18.
That registration is what an HVAC apprentice works under.
It is also the first rung: a registrant becomes eligible for the class exam after holding the card for 2 years, or 1 year plus 1 year of technical experience.
Federally, work that could reasonably be expected to violate the integrity of a refrigerant circuit requires EPA Section 608 certification, from which apprentices are exempt only while closely and continually supervised by a certified technician.
Plumbing apprentices register differently: with the Arkansas Department of Health, $25 per year, naming the master plumber they work under, and the Department of Health points plumbing apprentices to the Office of Skills Development for apprenticeship rules.
Arkansas's United Association local is UA Local 155, which covers the State of Arkansas and is listed in Little Rock.
The UA says nationally that its apprenticeships are registered with DOL, typically last five years, and cover plumbing, pipefitting, HVACR, welding and fire protection β so ask the hall which HVACR programs it is currently taking apprentices for.
On the sheet metal side of the trade, SMART Sheet Metal Local 78 is listed as Little Rock, Arkansas (office in Sherwood); the International Training Institute (ITI), jointly sponsored by SMART and SMACNA, reports more than 14,000 registered apprentices in the US and Canada, and says sheet metal apprenticeships run four or five years.
Our research confirmed the locals, not their current intake or entry standards, so treat this page as a list of confirmed programs and ask each hall what it currently registers.
Our research did not verify a registered HVAC apprenticeship run by PHCC, ABC or ACCA in Arkansas, so treat the national associations as places to ask rather than confirmed options: ABC describes itself as founded on the merit shop philosophy and reports more than 24,000 members, PHCC offers apprenticeship content through its online learning academy, and ACCA reports 60,000 professionals and over 3,000 company members.
Which chapters run HVAC programs is chapter-level detail the research did not verify.
One Arkansas rule does shape employer programs: a registrant can only perform work for an HVACR licensee, so an employer that puts an apprentice to work on HVACR systems must be an HVACR licensee.
If an employer offers to train you, ask whether its program is registered and confirm the license standing with the board.
Our research found no Arkansas list of HVACR related-instruction providers, community colleges or training centers, so ask each sponsor where its classroom hours are delivered and check with the board before you rely on any school's claim.
What the rule does confirm sits on the license side: an applicant for an HVACR class license with no licensing background must show at least two years' experience as an HVACR contractor or an employee of one, and board-approved training may substitute for that experience β the board's training approval is where formal instruction connects to licensure.
Federally, an apprenticeable occupation requires at least 2,000 hours of on-the-job learning, program terms may be time-based, competency-based or a hybrid, and DOL recommends a minimum of 144 hours of related technical instruction per year β a recommendation, not a requirement.
βApplicants for licensure with no licensing background shall present satisfactory evidence of having at least two (2) years' experience as an HVACR contractor or an employee of an HVACR contractor.β
You apply to the sponsor itself β the union hall or an employer's program β and ask whether it is currently taking apprentices and whether its program is registered.
Once you are working, you hold the HVACR registrant card: $25 per year, and you must be at least 18.
Federally, a registered apprentice must be at least 16 unless a higher minimum age is set by law; there is no federal maximum age, and rules bar discrimination against applicants aged 40 or older; a probationary period may not exceed 25% of the program length or 1 year, whichever is shorter; and pay follows a progressively increasing schedule tied to skill, with the entry wage not below the FLSA minimum wage where it applies.
Completion earns a certificate from the registration agency β it is not a trade license.
From there, a registrant who has held the card for 2 years, or for 1 year plus 1 year of technical experience, can apply to sit the HVACR class exam, which Prov proctors with board pre-approval.
Our guide to how to get an HVAC apprenticeship covers the application in depth.

Yes.
Arkansas requires anyone doing HVACR work to hold a class license or a registration.
If you are not a class holder, you carry the HVACR registrant card β $25 per year, and you must be at least 18 β and you can only work for an HVACR licensee.
Work that could reasonably be expected to violate the integrity of a refrigerant circuit also needs federal EPA 608 certification, from which apprentices are exempt only while closely and continually supervised by a certified technician.
The class levels, exam and fees are on our Arkansas HVAC license page.
The locals our research confirmed are UA Local 155, which covers the State of Arkansas and is listed in Little Rock, and SMART Sheet Metal Local 78, also Little Rock with an office in Sherwood.
The United Association says its registered apprenticeships typically last five years and cover HVACR; the International Training Institute, jointly sponsored by SMART and SMACNA, says sheet metal apprenticeships run four or five years.
Our research confirmed the locals but not their current intake, so contact each hall about applications.
Federal standards set the floor: an apprenticeable occupation requires at least 2,000 hours of on-the-job learning, program terms may be time-based, competency-based or a hybrid, and the 144 hours of related instruction per year is a recommendation, not a requirement.
United Association programs typically run five years.
Our research found no state hour total for Arkansas HVAC apprentices; for licensure, a registrant becomes eligible for the class exam after 2 years on the card, or 1 year plus 1 year of technical experience.
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 verified no Arkansas-specific apprentice wage figures, so ask each sponsor for its current schedule.
Our HVAC apprentice pay guide has the national picture.
It is the worker registration the HVACR Licensing Board issues to anyone doing HVACR work who does not hold a class license.
It costs $25 per year, applicants must be at least 18, and a registrant can only perform work for an HVACR licensee.
After holding the card for 2 years, or 1 year plus 1 year of technical experience, a registrant can apply to sit the class exam, which Prov proctors with board pre-approval.
