Arkansas · HVAC licensing · official-source guide
Arkansas licenses HVAC/R contractors at the state level through the HVACR Licensing Board, part of the Arkansas Department of Labor and Licensing. Contractors need a Class A, B, D or E license depending on scope, must pass a board exam, carry $250,000 liability insurance, and renew annually with 8 hours of continuing education. Technicians handling refrigerant also need federal EPA Section 608 certification.

Arkansas regulates heating, ventilation, air conditioning and refrigeration work at the state level through the HVACR Licensing Board, created by Arkansas Code 17-33-201 and housed inside the Arkansas Department of Labor and Licensing. The board has nine members appointed by the Governor and confirmed by the Senate: a department representative who serves as secretary, two Class A license holders, two Class B license holders, one mechanical engineer registered in Arkansas, one representative of a city or county HVACR inspection program, one consumer member with no financial interest in the industry, and one member of the Mechanical Contractors Association of Arkansas who holds a current state contractor's license. Members serve four year terms and may not serve more than two successive terms. The board writes the rules that govern licensing, currently published as Title 17 Chapter XLV Part 261 of the Arkansas Code of Rules, sets the fee schedule, adopts the mechanical code the state uses (the International Mechanical Code, 2021 edition), reviews exam applications, and disciplines licensees. Day to day administration runs through the department's Code Enforcement Division. A separate rule, Arkansas Code 17-33-104, matters a great deal to a contractor building a multi city book of business: once a person holds an Arkansas HVACR license or registration, no city or county in the state, including Little Rock, Fort Smith, Fayetteville, Springdale or Jonesboro, may require a separate local HVAC license to do the same work. Local building departments can still require permits and inspections on individual jobs, but they cannot layer a second licensing requirement on top of the state one. That single state license, not a patchwork of city licenses, is the credential that matters for advertising and bidding work anywhere in Arkansas.
Arkansas Code 17-33-303 and board rule 261-103 set out five classes of HVACR license plus a registration category, and the class a contractor holds determines exactly what work that contractor may sell and perform. Class A carries no limit on BTUH or horsepower and covers full scope HVACR work, including installing, servicing and selling heating, air conditioning and refrigeration systems of any size. Class B is capped at air conditioning systems of no more than twenty five tons of cooling capacity or 1,000,000 BTUH of heating input per unit, and refrigeration systems of fifteen horsepower or less, which covers the great majority of residential and light commercial equipment. Class D is limited to sheet metal ductwork; a Class D holder may fabricate and install ducts but is barred from selling, installing or servicing the HVACR equipment itself. Class E covers refrigeration work of any horsepower but excludes heating and air conditioning equipment used for human comfort, so it fits a contractor who only works on commercial refrigeration or process cooling. Class L is a restricted lifetime license available at no charge to a license holder who is at least sixty five years old and has held an Arkansas HVACR license in good standing for ten consecutive years; it is capped at fifteen tons of cooling or 1,000,000 BTUH of heating per unit, and the holder may not install new or replacement equipment or employ registrants. Anyone who performs HVACR work but does not hold one of these class licenses must instead hold a current HVACR registration and can only work under a Class A, B, D or E license holder, who is responsible for keeping that employee's registration active. Choosing the wrong class, for example running a full service shop on a Class D ductwork license, is itself a licensing violation.
To apply for a Class A, B, D or E license, an applicant must be at least eighteen years old and file an application with the Department of Labor and Licensing on the board's forms, specifying the class sought. Board rule 261-104 requires an applicant with no prior HVACR license anywhere to show at least two years of experience as an HVACR contractor or as an employee of one, documented through employer records, affidavits or other evidence from people who can attest to the applicant's work history. The board may accept approved HVACR related educational training in place of some of that experience if the applicant supplies transcripts, but the rule is explicit that apprenticeship, education or training can never be made a mandatory prerequisite for licensure on top of the experience path. A separate earn and learn track under rule 261-121 lets an applicant who completes a qualifying HVACR apprenticeship, passes the required exam and meets the other licensing conditions get licensed on that basis, and the apprenticeship cannot be made to run longer than the number of hours the board sets except where federal law requires more. The board does not run criminal background checks, though it can ask about convictions on the application, and certain serious convictions listed in Arkansas Code 17-3-102, such as violent or sexual offenses, can disqualify an applicant subject to a waiver process that looks at how long ago the offense occurred and the applicant's history since. Applicants who intend to work as the designated license holder for a company are personally responsible for keeping all of that company's HVACR employees registered.

An applicant with no HVACR license in any other state must pass a board approved examination before Arkansas will issue a Class A, B, D or E license, and a failed attempt does not bar retesting. The department's HVAC/R page states that Arkansas contractor exams are proctored by Prov, a national licensing and examination services provider that operates as provexam.com, and that a candidate must be pre-approved by the board before scheduling a seat. Board rule 261-105 requires the department to offer Class A, B, D and E exams at least four times a year, or more often if the board decides that is appropriate, so a rejected or delayed applicant is not stuck waiting a full year for another sitting. A separate accommodation in rule 261-104 lets an applicant skip the Arkansas exam entirely if the applicant already holds a current, good-standing HVACR license from another state, territory or district whose licensing law is substantially similar to Arkansas's, meaning that state has adopted a national model mechanical code and uses a comprehensive exam built and proctored by a national testing agency; that applicant still pays the Arkansas license fee and must not have had the out of state license revoked for bad faith, a law or ethics violation, and must not be under suspension or probation anywhere. This exam-waiver path is separate from a formal state to state reciprocity agreement, and it applies license by license rather than through a blanket arrangement between Arkansas and another state's board.
Arkansas Code 17-33-204 sets the ceiling on what the HVACR Licensing Board may charge, and board rule 261-106 confirms the board is currently charging those ceiling amounts. The annual license fee is $200 for a Class A license and $150 each for a Class B, Class D or Class E license; the Class L lifetime license carries no charge at all. An annual HVACR registration, the credential an employee needs to work under a licensed class holder, costs $25 and is the license holder's responsibility to keep current for every registered employee. The exam fee for a Class A, B, D or E applicant is $100 for each exam sitting, charged separately from the license fee. The board waives the initial license fee, though never the exam fee, for an applicant who documents that they receive assistance through Arkansas Medicaid, SNAP, the WIC program, TANF or the Lifeline Assistance Program, or who was approved for unemployment in the prior twelve months, or whose income does not exceed 200 percent of the federal poverty guidelines. Beyond licensing itself, rule 261-114 sets a separate schedule for the department's HVACR installation inspections: $25 for the first $1,000 of a job's valuation or any fraction of it, plus $2 for each additional $1,000 or fraction, capped at $1,000 in total inspection fees on any single job, with each reinspection billed at a flat $25. The department does not charge to investigate a consumer complaint or to assist local inspection authorities.
Arkansas does not require an HVACR contractor to post a surety bond. Instead, board rule 261-117(d) requires every Class A, B, D or E license holder to either carry their own general liability insurance covering the work they perform or be covered under an employer's policy that meets the same minimum, and Arkansas Code 17-33-202(8) is the statutory authority that lets the board set that minimum by rule. The minimum coverage the rule sets is $250,000, applied per individual licensee for a self-carried policy or per licensed employee for an employer-provided policy. Proof of that coverage has to be handed to the board when a license is first issued and again at every renewal, not just kept on file at the contractor's office. The rule does carve out two narrow waivers from the insurance requirement: a licensee whose only HVACR work is maintaining and repairing equipment owned by their employer, such as an in-house facilities technician, or a licensee who works purely as an instructor at a recognized school or apprenticeship program and does no for-profit HVACR work. Anyone using either waiver has to submit a letter at each renewal, from the employer's or school's human resources office or another responsible official, confirming the not-for-profit nature of the position. Because the insurance minimum is set by board rule rather than by the statute itself, the board could raise or lower it in a future rulemaking, so a contractor renewing a license should confirm the current figure against the board's own rule rather than assume it is fixed permanently at $250,000.
An Arkansas HVACR license or registration expires on the last day of the month, one year from the date it was issued, under Arkansas Code 17-33-306 and board rule 261-105. To renew, the licensee submits the department's renewal form and the applicable license or registration fee before that expiration date. Rule 261-120 blocks renewal of any Class A, B, D or E license unless the licensee has completed at least eight hours of continuing education tied to the current International Mechanical Code cycle published by the International Code Council, taken through a course the board has approved in advance; the board itself offers an annual eight hour course at no charge. Those hours are due before the final year of the code cycle, and a licensee who misses them has the class license suspended until a verifiable completion certificate reaches the board, on top of whatever other civil penalty applies. A license that lapses purely for nonpayment of the renewal fee can be reinstated on payment of the current and back license fees plus a late fee of $10 for each month of delinquency, calculated from the first day of each calendar month, with no apprenticeship, education or retraining required as a condition of reinstatement; an amended experience record covering the lapsed period must still be filed. If the delinquency runs longer than three years, the board requires the applicant to retake the license exam before reinstating. A license that the board has revoked for cause, rather than merely lapsed, cannot be reapplied for until a full year after the date of revocation.
The department's own HVAC/R page states plainly that the Arkansas HVACR Board has no reciprocal licensing agreements with any other state licensing board at this time, even though board rule 261-112 gives the board authority to enter such agreements and lays out how a reciprocal applicant would be treated if one existed: no exam, no apprenticeship or training requirement, just the license fee and proof the out of state license is in good standing and substantially similar to Arkansas's. Absent a signed agreement, an out of state HVACR contractor's practical paths into Arkansas are the exam-waiver accommodation in rule 261-104 for a substantially similar license, described above, or a temporary license. Under rule 261-104(c), the board issues a temporary Class A, B, D or E license immediately on request to an applicant who already holds an out of state HVACR license in good standing, pays the fee and is not under suspension, revocation or probation anywhere; that temporary license is valid ninety days, and the holder must schedule the Arkansas exam within sixty days of receiving it or the temporary license is forfeited. Rule 261-119 gives a fuller benefit to military connected applicants: a uniformed service member stationed in Arkansas, a veteran who establishes Arkansas residency, or the spouse of either, gets automatic Class A, B, D or E licensure on paying the fee and showing a substantially equivalent out of state license, with no exam. A deployed service member's or spouse's license expiration is pushed back 180 days after the return from deployment, and continuing education is fully waived for that same 180 day window.
Arkansas Code 17-33-301 makes it unlawful to perform HVACR work without the license or registration the chapter requires, and unlawful for any licensee to let an unlicensed person use their license number for any purpose. Enforcement runs through the HVACR Licensing Board rather than a criminal court: Arkansas Code 17-33-105 and board rule 261-116 both authorize a civil penalty of up to $1,000 for each violation, and each day a violation continues can be counted as a separate violation for that purpose, though no penalty can actually be assessed until the accused has had a hearing under the Arkansas Administrative Procedure Act. Before a penalty is assessed, the responsible license holder must first be given a chance to correct the violation, and rule 261-116 specifically allows a person who did unlicensed work, or licensed work outside the scope of their class, to bring in a properly licensed HVACR contractor to complete or fix the work at that person's own expense. Beyond the civil penalty, the board can go to court to enjoin further violations, force compliance, order remedial work, and recover its enforcement costs and damages. A significant practical consequence sits outside the penalty itself: any person who was required to be licensed but was not is barred by statute from filing a mechanic's and materialman's lien, a laborer's lien, a repairman's lien or any other artisan's lien over that unlicensed work, which means an unlicensed contractor has no lien remedy at all if a customer simply refuses to pay.
Arkansas Code 17-33-304 requires every licensed HVACR contractor to display their license number on all business vehicles and in every form of advertising, in the manner the board's rules prescribe, and board rule 261-117 spells out exactly what that manner is. The license number and company name must appear in a prominent, legible manner in letters no smaller than two inches tall on both sides of every service and installation vehicle used for the air conditioning and refrigeration work. At every job site where new HVACR work is underway, the contractor must post a sign no smaller than 8.5 by 11 inches showing the company name, license number and phone number. Business cards for anyone who performs HVACR work must carry the same three items: company name, license number and business phone number, and the rule gives a model format of 'HVACR LICENSE #0000001' followed by the company name, address and phone number. A license holder must also notify the board in writing within thirty days of any change to their permanent mailing address, business affiliation, business location or business phone number, and must request a license revision, with the applicable fee, whenever those details change on the license itself. Failing to display the license as required, like any other rule violation, exposes the contractor to the same civil penalty of up to $1,000 per violation described in Arkansas Code 17-33-105 and board rule 261-116, since the display requirement is itself a provision of the chapter and the board's rules that a licensee must follow.
The Arkansas Department of Labor and Licensing publishes a public HVAC Roster on its website that lets anyone search current HVACR license and registration holders by first name, last name or city, at no charge and with no login required. That roster is the direct way for a homeowner, property manager or general contractor to confirm before hiring that a person or company actually holds an active Arkansas HVACR license, and at what class. Board rule 261-114(d) backs that lookup up on the job site itself: every licensed HVACR contractor and registrant must carry their license, in paper or digital form, on their person or immediately available while doing HVACR work, along with a photo ID, and must produce both to a state or local HVACR inspector, building inspector or fire marshal on request. The department's HVAC/R page also hosts a Code Enforcement complaint form specifically for reporting problems with HVAC work, where a complainant can enter the license number, object number or applicant/subscriber number of the business or individual involved, describe the work and the complaint, and note how the work was paid for and whether receipts exist. Filing that complaint form is the department's channel for a consumer who suspects a contractor is working without the proper class of license, or who has a dispute over completed HVACR work, and it feeds directly into the same board investigation and hearing process that can lead to a civil penalty or license suspension.

Arkansas Code 17-33-102 and the matching board rule 261-118 carve out a specific list of work and people the HVACR licensing chapter does not reach. On the equipment side, the exemption covers household appliances, American Gas Association approved unvented space heaters, factory assembled self-contained refrigeration equipment of one and a half horsepower or less with no refrigerant lines running outside the cabinet, factory assembled window-type air conditioning units of 36,000 BTUH or less that are not connected to ductwork, and window, attic, ceiling and wall fans installed in a residence. Poultry hatching, primary processing or further processing operations are exempt outright regardless of the equipment involved. On the person side, a homeowner may do HVACR work on a building they own and occupy as their own home, and the same goes for work on their own farm; the exemption also covers utility company employees doing work incidental to the utility's own construction and maintenance, anyone working on a motor vehicle, an architect or registered engineer who designs an HVACR system purely for design criteria without installing it, and a hospital employee whose HVACR work is incidental to the hospital's operation, subject to separate Department of Health rules for licensed healthcare facilities. A person licensed to work on liquefied petroleum gas appliances under the separate Liquefied Petroleum Gas Board is exempt from HVACR licensing for that LP gas work, and a pipefitter, welder, well driller, sheet metal worker or plumber enrolled in or having completed a state-approved apprenticeship can work under a Class A, B, D or E licensee within the bounds of their own trade license. Every exempt person still has to follow any local permit or inspection requirement that applies.
The HVACR Licensing Board only issues the trade license that lets a person perform HVACR work; it is a separate agency, the Arkansas Contractors Licensing Board, that regulates the broader construction license some of the same HVAC/R companies also need once a job's size or type crosses certain thresholds. The department's own HVAC/R page tells contractors to contact the Contractors Licensing Board directly for that separate licensing track. Under the board's own published guidance, a Commercial License is required for any project that is not a single family residence once the value of labor and materials reaches $50,000 or more; below that dollar figure on a commercial job, a Subcontractor Registration Certificate can substitute for a full license when the HVAC contractor is working under a properly licensed prime contractor rather than contracting directly with the property owner. On single family residential work, a Home Improvement License is required for specialty work, which can include HVAC installation as part of a larger remodel, once the project passes $2,000 in labor and materials, and a Residential Builders or Residential Remodelers License applies once the work involves building a home or making major structural changes above that same $2,000 threshold. In practice, an HVACR license holder who only installs, services and repairs heating, cooling and refrigeration equipment typically operates under the HVACR license alone, but the same company taking on a larger design-build or whole-home construction contract, or acting as the prime contractor on a big commercial job, needs to layer an Arkansas Contractors Licensing Board license or registration on top of its HVACR license.

An Arkansas HVACR license is not the only credential a technician needs to legally handle refrigerant. Section 608 of the federal Clean Air Act, codified at 40 CFR Part 82 Subpart F and administered by the U.S. Environmental Protection Agency, establishes the National Recycling and Emission Reduction Program, which bans intentionally venting ozone-depleting refrigerants and their substitutes, including HFCs, while maintaining, servicing, repairing or disposing of air conditioning or refrigeration equipment. Anyone who performs that kind of work on covered equipment, whether or not they also hold an Arkansas Class A, B, D, E or L HVACR license, must hold EPA Section 608 technician certification, which is a federal requirement layered on top of, not a substitute for, the state license. The EPA does not issue the certification card itself; certification comes from an EPA-approved certifying organization after the technician passes a proctored exam covering a mandatory Core section plus one or more specialty sections: Type I for small appliances, Type II for high-pressure appliances, and Type III for low-pressure appliances, with a Universal certification available to a technician who passes all three specialty sections in addition to the Core. Which type or types a technician needs depends on the equipment they actually service, so a residential Class B contractor working on typical split system air conditioners and heat pumps generally needs Type II at minimum, while a Class E refrigeration specialist working on commercial low-pressure chillers would need Type III or the Universal credential. A lost card is replaced through the certifying organization that issued it, not through EPA directly.
These are common details other guides publish about Arkansas, but we could not verify them from the agency source. Confirm them directly before relying on them.
Yes. The HVACR Licensing Board, part of the Arkansas Department of Labor and Licensing, issues Class A, B, D, E and L HVACR licenses and HVACR registrations under Arkansas Code 17-33-101 et seq., and no city or county in Arkansas may impose a separate HVAC license on top of it.
Class B covers air conditioning systems up to 25 tons or 1,000,000 BTUH of heating input and refrigeration systems of 15 horsepower or less, which fits most homes. Class A has no size limit at all, so it also covers residential work plus larger commercial systems.
Board rule sets the annual license fee at $200 for Class A and $150 each for Class B, D or E, plus a separate $100 exam fee per sitting. Class L lifetime licenses are free. HVACR registration for an employee working under a licensee costs $25 a year.
One year. The license expires on the last day of the month, one year from its original issue date, and the licensee must file the renewal form and fee before that date.
No. Board rule requires a Class A, B, D or E license holder to carry, or be covered by, general liability insurance of at least $250,000 per licensee or per licensed employee. Arkansas does not impose a separate bond requirement for this license.
Arkansas's HVACR Board has no reciprocal agreement with any other state's board right now. An applicant with a substantially similar out of state license can skip the Arkansas exam under board rule, or get a 90 day temporary license while scheduling the exam.
The HVACR Licensing Board can assess a civil penalty of up to $1,000 per violation, with each day of an ongoing violation counted separately, after giving the person a hearing. An unlicensed person also loses the right to file a mechanic's or laborer's lien for that work.
Yes. State law requires the license number on all business vehicles and every form of advertising, and board rule specifies letters at least two inches tall showing the license number and company name on both sides of service and installation vehicles.
The Department of Labor and Licensing publishes a free HVAC Roster search by first name, last name or city on its website. A licensee is also required to carry the license and a photo ID on the job and show both to any inspector on request.
Only in certain cases. A separate Arkansas Contractors Licensing Board commercial license is required once a non-residential project reaches $50,000 in labor and materials, and a home improvement or residential builder license applies to qualifying single-family work over $2,000, on top of the HVACR trade license.
At least 8 hours per current International Mechanical Code cycle, taken through a board-approved course, completed before the final year of that code cycle. Missing the requirement gets the license suspended until a valid completion certificate is filed.
Yes. Federal law under Clean Air Act Section 608 requires anyone who maintains, services, repairs or disposes of covered air conditioning or refrigeration equipment to hold EPA Section 608 technician certification, in one or more of the Core, Type I, Type II, Type III or Universal categories, regardless of state license class.
