HVAC Contractor License in Arkansas: Requirements, Qualifier, Bond and Exams
Yes — Arkansas licenses HVACR work statewide, and a contracting business does it with two things: an HVACR organization registration for the company, and a Class A, B, D or E licensee as its designated license holder.
There is no separate HVAC contractor license beyond the class license.
Exams are proctored by Prov, new class holders must carry general liability insurance, and the class licenses cost $150 to $200 per year (Class L is no charge).
Commercial projects of $50,000 or more also need an Arkansas Contractors Licensing Board license.

At a glance
Yes.
Anyone doing HVACR work needs a Board class license or a registrant card, and a contracting business registers as an HVACR organization with a Class A, B, D or E licensee as its designated license holder.
The Arkansas HVACR Licensing Board (the State HVAC/R Board), within the Arkansas Department of Labor and Licensing.
Class A (unlimited), Class B (not more than 25 tons cooling per unit under the rule text we read), Class D (sheet metal ductwork only), Class E (refrigeration only) and Class L (lifetime, service only); the 2024 statute compilation also still shows a Class C the rule text does not list.
A designated license holder: the Class A, B, D or E licensee responsible for the HVACR work.
Applicants with no licensing background need at least 2 years' experience as, or working for, an HVACR contractor; board-approved training may substitute.
HVACR contractor exams proctored by Prov, with Board pre-approval; each Class A, B, D or E exam costs $100.
A business-and-law test applies to the Contractors Licensing Board commercial license for work of $50,000 or more.
New class holders must carry general liability insurance.
No minimum amount and no bond amount are stated in the sources we read — ask the Board.
Class A $200 per year; Class B, D or E $150 per year; Class L no charge; registrants $25 per year.
Licenses expire on the last day of the month one year after issuance, and renewal requires at least 8 hours of Board-approved continuing education per International Mechanical Code cycle.
None.
The Board states it has no reciprocal licensing agreements with any other state; out-of-state licensees from substantially similar states may be approved with examination.
The Arkansas HVAC license ladder
- Class DSpecialty
Limits the licensee to HVACR work on sheet metal ductwork.
- Class ESpecialty
Limits the licensee to refrigeration-only work.
- Class BContractor
HVACR work on air conditioning systems of not more than 25 tons of cooling capacity per unit (1,000,000 BTUH of heating; refrigeration 15 hp) under the rule text we read — the department's 2024 statute compilation still lists Class B at 15 tons.
- Class AContractor
Unlimited HVACR work, with no equipment-size cap.
- Class LOther
A lifetime license requiring age 65 and long good standing as a class holder; it is service-only, and a Class L holder may not employ registrants to perform HVACR work.
Does Arkansas license HVAC contractors statewide, or only locally?
Statewide.
The Arkansas HVACR Licensing Board, part of the Arkansas Department of Labor and Licensing, requires every individual who designs, installs, services or repairs any HVACR system to hold an HVACR license or registration.
A business does not get a separate contractor license on top: it first holds an HVACR organization registration, and the Class A, B, D or E licensee responsible for its HVACR work is its designated license holder.
Once licensed, the licensee must display the license number and company name on all business vehicles and in all forms of advertising, so the license follows your trucks and your ads.
Which agency issues the license, and what are the classes?
The Arkansas HVACR Licensing Board — the State HVAC/R Board in the Arkansas Department of Labor and Licensing — issues the class licenses and registrations.
Under 17 CAR Part 261, the classes are Class A (unlimited), Class B (not more than 25 tons of cooling capacity per unit, 1,000,000 BTUH of heating, and refrigeration 15 hp), Class D (sheet metal ductwork only), Class E (refrigeration only) and Class L (a lifetime license limited to service work).
One caution: the department's 2024 statute compilation still describes a 15-ton Class B and a Class C service license, neither of which appears in the rule text we read, so confirm the current class definitions with the Board before you pick one.
Who can be the qualifier, and what experience do they need?
Arkansas's version of a qualifier is the designated license holder: the Class A, B, D or E licensee who is responsible for the HVACR work the business performs, with the company first holding an HVACR organization registration.
An applicant for a class license with no licensing background must show satisfactory evidence of at least 2 years' experience as an HVACR contractor or as an employee of one, and board-approved training can substitute.
The other route runs through registration: holding a registrant card for 2 years, or 1 year plus 1 year of technical experience, makes a registrant eligible for the contractor exam.
Registrants and class-license applicants must be at least 18.
“"Designated license holder" means the Class A, B, D, or E licensee who is responsible for the HVACR work performed;”
Which exams must you pass: trade, and business and law?
The HVACR contractor exams are proctored by Prov, and candidates must be pre-approved by the Board before they sit.
Each Class A, B, D or E exam costs $100.
Our sources name no business-and-law exam for the Arkansas HVACR class license — the board pages we read list none.
The one business-and-law test in what we read belongs to a different board: the Arkansas Contractors Licensing Board requires a commercial license, which comes with a business and law test, for work of $50,000 or more on any project other than a single-family residence.
“HVAC/R contractor examinations are proctored by Prov, a nationally recognized licensing and examination services provider.”
What bond and insurance does Arkansas require?
New HVACR class holders must carry general liability insurance — the Board's page states that all applicants are required to possess it.
Neither an insurance minimum nor any bond amount is stated on the board pages we read, so confirm the current coverage limits with the Board before you file.
Our research did not surface a surety bond requirement for the class license, and we would not treat that as a promise the Board will not ask for bond documentation at application time.
“All applicants are required to possess general liability insurance”
What does it cost, and how often is it renewed?
License fees run $200 per year for Class A and $150 per year for Class B, D or E; Class L carries no charge, and each Class A, B, D or E exam costs $100.
Your crew members who hold no class license carry registrant cards at $25 per year.
Every license expires on the last day of the month one year from its original issuance, and no HVACR license renews unless the licensee completes at least 8 hours of Board-approved continuing education per current International Mechanical Code cycle.
“All licenses called for under this part shall expire on the last day of the month one (1) year from the original date of issuance.”
Does Arkansas have reciprocity with other states?
No. The Arkansas Department of Labor and Licensing's State HVAC/R Board states that it has no reciprocal licensing agreements with any other state licensing boards for HVAC/R licensing at this time.
An out-of-state license is not worthless here: licensees from states the Board treats as substantially similar may be approved, with examination.
Treat your out-of-state license as the start of the Arkansas conversation, not the end of it, and confirm your situation with the Board before you bid work.
“The Arkansas Department of Labor and Licensing's State HVAC/R Board has no reciprocal licensing agreements with any other state licensing Boards for HVAC/R licensing at this time.”
What happens if your qualifier leaves?
The license that matters is held by a person, so when your designated license holder leaves, the company is left holding an organization registration with no Class A, B, D or E licensee responsible for its HVACR work.
The board pages we read do not state a deadline for replacing a designated license holder, and they do not say whether one class holder may qualify multiple companies.
Our research also did not find a public HVACR license lookup, so verify a company's license holder directly with the Board.
Confirm the replacement rule with the Board before you are in that position, and line up the next designated license holder before the current one gives notice.
Is there a job-size threshold that adds a second license?
Two thresholds matter in Arkansas, and both belong to the Arkansas Contractors Licensing Board rather than the HVACR Board.
A commercial license, which comes with a business and law test, is needed for work of $50,000 or more, including labor and materials, on a commercial project.
A home improvement license is needed for specialty work on a single-family residence when the project is more than $2,000.
The Contractors Licensing Board pages we read did not say how home-improvement licensing interacts with an HVACR class license, so confirm which registrations your mix of work requires with the ACLB.
You can check a contractor license on the ACLB's Find A Licensed Contractor page.

Frequently Asked Questions
Do my technicians need their own Arkansas HVACR credentials to work for me?
Yes.
Workers who are not class holders must hold a current HVACR registration — a registrant card — and can only perform work for an HVACR licensee.
The registrant fee is $25 per year, and registrants must be at least 18.
The full worker-side ladder, including how a registrant works up to a class license, is on our Arkansas HVAC license page for individuals.
Is there a separate HVAC contractor license in Arkansas?
No separate one that our research found: contracting runs on the HVACR class license plus an HVACR organization registration, with the Class A, B, D or E licensee responsible for the work serving as the designated license holder.
Two Contractors Licensing Board licenses also exist for bigger work: a commercial license for work of $50,000 or more, and a home improvement license for specialty work on a single-family residence over $2,000 — how they interact with an HVACR class license was not stated in the pages we read.
Can one Arkansas class holder qualify more than one company?
We could not confirm that either way.
The board pages we read did not say whether one class holder may serve as the designated license holder for multiple registered organizations, so ask the Board before you structure two businesses around one licensee.
What is clear is the base rule: a business must first hold an HVACR organization registration, and its HVACR work needs a Class A, B, D or E licensee responsible for it.
What happens if my designated license holder quits?
The designated license holder is a specific Class A, B, D or E licensee, so a departure leaves your registered company without the person responsible for its HVACR work.
The board pages we read set no replacement deadline, and our research found no grace period, so confirm the current rule with the Board and recruit the next license holder before your current one gives notice.
How much does an Arkansas HVACR class license cost per year?
$200 per year for Class A, $150 per year for Class B, D or E, and no charge for Class L.
The exam for a Class A, B, D or E license costs $100, licenses expire on the last day of the month one year from issuance, and renewal requires at least 8 hours of Board-approved continuing education per International Mechanical Code cycle.
