Who Needs a License in Arkansas?
Anyone performing HVAC, ventilation, air conditioning, or refrigeration contracting in Arkansas must meet HVAC license requirements in Arkansas prior to offering, bidding, or executing work. The requirement applies regardless of project value, there is no dollar threshold for exemption.
Individuals or businesses must be licensed if their work includes the installation, repair, maintenance, service, alteration, or modification of heating, cooling, ventilation, or refrigeration systems. This includes both residential and commercial jobs.
Every licensee (Class A–E) must supervise registrants (employees) under their authority, and all staff performing regulated work must be formally registered. It is important to note that a general contractor license does not exempt anyone from holding the correct Arkansas HVAC license.
Distinction: Employees vs. Contractors
The person or business named on the license is responsible for their employee registrants. Employees need a separate registration, but contractors, subcontractors, and business owners must hold the main HVAC license. Registrants can only work under the supervision and on behalf of the licensee.
Exemptions and Special Cases
There are a few exemptions from HVAC license requirements in Arkansas. For example, owner-occupants working on their primary residence, unpaid designers, and certain hospital employees performing limited maintenance may be exempt. However, nearly all paid HVAC work for others, regardless of scope or project size, requires the appropriate license.
HVAC License Types
Contractors must select one of several license classes, each with limits and permitted job scopes as defined in Arkansas regulations. Understanding which class matches your HVAC license requirements in Arkansas is crucial before applying.
Class A: Unlimited capacity for both heating and cooling (no tonnage/BTUH limit), full HVACR and appliance installation, electrical, and fuel gas supply, including all scales residential, commercial, and industrial.
Class B: Limited to 25 tons cooling or 1,000,000 BTUH heating per unit, refrigeration under 15 HP. Allows appliance fitting and electrical-gas connections for relevant units.
Class C: Service/repair only, may service, repair, or replace any component but not install new HVACR equipment or systems.
Class D: Sheet metal and ductwork specialist, performs duct fabrication, installation, and repair, but not HVACR appliance or system installation/service.
Class E: Refrigeration contractor, install, modify, repair, or service refrigeration equipment (such as walk-in coolers or process refrigeration), possibly including electrical/gas to appliance, but not comfort HVAC system installation.
Class L (Lifetime): Special license for those 65+, previously qualified for A-E. Covers service/maintenance (not installation) for up to 15 tons cooling/1,000,000 BTUH, no employees allowed.
Each class of license is distinct, contractors cannot combine classes on a single license or apply upgrades without completing the process anew. Choosing the wrong class limits your ability to contract for certain types or sizes of work, a key part of HVAC license requirements in Arkansas.
How to Meet HVAC License Requirements in Arkansas: Steps to Licensure
Obtaining an HVAC license in Arkansas involves a sequence of required steps for all applicants. Review each step below for precise HVAC license requirements in Arkansas, as omitting any requirement delays approval.
Step 1: Eligibility and Experience
Confirm eligibility: For Classes A-E, applicants must be at least 18 years old; for Class L (Lifetime), applicants must be 65 or older and previously eligible for A-E.
Accumulate at least two years of lawful HVACR experience (contractor or employee), or approved education with supporting transcripts. If counting education in lieu of experience, obtain a list of Board-approved programs and verify with them before applying.
Step 2: Application Submission
Download the official, most recent application form for the desired class (see official ADLL site or visit in person).
Complete the application thoroughly. Sign and notarize it where required. Attach documentation of experience, education (if used), and any other supporting evidence per the instructions.
Mail the original, notarized application to the Board's physical address as listed on the form; there is presently no online application process. Keep copies of all records in case of mail delays or follow-up inquiries.
Step 3: Board Review and Examination
Wait for the Board to review your file. If accepted, you will receive an authorization to sit for the required Board exam (via Prov Testing Service or authorized provider).
Schedule and take the Board-approved exam. You may choose computerized or written exam options per current Board policy.
After passing the exam, provide any required proof of insurance coverage and pay all applicable license and registrant fees (if employing others).
Once all steps are complete and the Board is satisfied, you are issued a license valid for one year. You must display your license at your business, on work vehicles, and present it at job sites as required under Arkansas regulations.
All documents and applications must be complete and accurate. The Board may request further information or clarification, so remain available for follow-ups until you receive your license. Applications with incomplete documentation or false information may be denied.
Application Requirements
The HVAC license requirements in Arkansas include experience, age, and several key documents. Understanding these requirements helps make your application go smoothly and on time.
Experience and Age
For Classes A-E, you must be at least 18 years old and have two or more years of HVACR experience either as a contractor or employee. Experience must be documented by affidavits, employer letters, or educational transcripts if you are substituting approved coursework for time on the job.
Insurance and Other Documentation
The Board requires you to show proof of insurance at issuance and at each renewal. While no specific minimum coverage amount is listed in published rules, you must provide evidence of insurance as a condition for licensure to cover possible liabilities on HVAC projects.
No bond is specifically required to meet HVAC license requirements in Arkansas, nor is a financial statement necessary as part of your initial application or renewal for standard license classes.
Background and Legal Disclosures
The Board may ask about criminal convictions, but does not perform fingerprint background checks. Any history must be reported honestly. Failure to disclose required information can result in denial or later revocation of your license.
There is no requirement for EPA 608 certification within Arkansas' official license procedure. However, if you work with regulated refrigerants, federal Environmental Protection Agency rules may separately require 608 certification.
Exams
Each applicant for Classes A, B, C, D, or E must pass a Board-approved HVAC exam as part of the HVAC license requirements in Arkansas. The exam provider is currently Prov, a national exam administration company.
Exam Details
Format: Written or computerized exam options are offered at Board-specified locations and times.
Frequency: Exams are administered at least four times per year, or at additional times as determined by the Board based on demand.

Renewal and Continuing Education
All licenses are valid for one year, and annual renewal is mandatory to stay compliant with HVAC license requirements in Arkansas. The renewal date is one year from initial issuance.
Renewal Process
To renew your license, submit a renewal application (form available at the Board's site), pay the relevant fee for your class, and provide up-to-date proof of insurance. If there have been significant changes to your experience or employment, you may need to submit amended records.
Late renewals are subject to a $10 per month penalty, and prolonged lapse may require you to retake the qualifying exam before reinstatement. Contractors with a lapsed license must complete a reinstatement application and are not permitted to work until fully active.
Continuing Education (CEU)
The Board may require up to eight hours of continuing education per International Mechanical Code cycle (typically a three-year span) as part of maintaining current knowledge. However, not all licensees are required to complete CE every year, requirements are established by the Board, so check with the Board each cycle to confirm. Official approved CE provider lists are posted online.
Reciprocity
No formal reciprocity agreements exist between Arkansas and any other state for HVAC licensure as of 2026. You may not transfer an out-of-state HVAC license directly to Arkansas.
The Board may, however, use discretion to grant reciprocity if the out-of-state jurisdiction is considered “substantially similar.” This is handled on a case-by-case basis, and applicants must submit full documentation, the usual application, and pay all appropriate fees. Mutual recognition is rare and is not guaranteed for any state, so you must verify each instance with the Board before proceeding.
