Iowa to Arkansas: master HVAC technician license reciprocity

Endorsement· Board reviewVerified September 15, 2026· 6 sources

Arkansas has no reciprocity agreement with Iowa. A Iowa master HVAC technician applies by endorsement.

Reference only, not legal advice. Rules change; confirm with the licensing board before you apply. Full disclaimer.

Licensure on a substantially similar out-of-state license (all states; no agreements exist)

The board reviews your out-of-state credentials case by case. Some exam is usually still required, often only a law or code exam.

Because the Board has no reciprocal agreements, every out-of-state applicant follows the same rule-based endorsement path. Rule §V(A)(3) and the license application direct the Board to approve a Class A, B, C, D or E applicant who is currently licensed in another state or political subdivision whose HVACR licensing laws are substantially similar to Arkansas's, that is, a jurisdiction that has adopted a national model mechanical code and uses a comprehensive exam created and proctored by a national examination agency or equivalent, provided the license is in good standing, has never been revoked for bad faith or a violation of law, rule or ethics, is not suspended or on probation, the applicant is competent in the field and pays the class license fee; apprenticeship, education or training may never be made a condition. The Board reviews each license case by case: the applicant files the HVACR License Application with a copy of the out-of-state license, a form completed by the origin board showing licensing status, exams administered and the mechanical code used, and a list of every state of past or present licensure. Rule §V(A)(4) requires the Prov exam only of candidates who hold no license in another state, so an applicant whose origin license is not substantially similar (for example a local or registration-only credential, or one issued without a national exam) qualifies instead through two years of documented experience and the class exam ($80). While the review is pending the Board issues a 90-day temporary permit on request, on the same good-standing conditions, and the applicant must attend the scheduled exam if one is required.

The department's page says the Board has 'no reciprocal licensing agreements'; rule §XIII (License by Reciprocity) nonetheless describes the exam-free process for a substantially similar license, and rule §V(A)(3) is drafted as a mandatory approval, so the practical mechanism is endorsement on the Board's finding of substantial similarity rather than an agreement. Rule §V(A)(3) literally reads 'approve ... with examination', which conflicts with §V(A)(4) and §XIII; the application form repeats the same wording. Rule §XX grants automatic licensure to uniformed service members, veterans and their spouses holding a similar out-of-state license. Arkansas pages do not mention EPA Section 608; it is listed because it is a federal requirement.

You must have no disciplinary action or unresolved complaints on your record.
You must document at least 4,000 hours of qualifying work experience.Only for applicants whose origin license is not substantially similar or who hold no license: rule §V(A)(5) requires two years of experience as an HVACR contractor or employee of one, shown by notarized employer affidavits; Board-approved education may substitute.

How Arkansas licenses master HVAC technicians

Arkansas master HVAC technician · “HVACR License, Class A (unlimited) to Class E (refrigeration)”

Statewide license

Verified September 15, 2026· 5 sources

Issued by Arkansas HVACR Licensing Board (Department of Labor and Licensing, HVAC/R Section)

Arkansas's highest HVAC credential is the HVACR license issued in five classes by the HVACR Licensing Board: Class A (unlimited), Class B (systems up to 15 tons cooling, 1,000,000 BTUH heating or 15 hp refrigeration), Class C (service and repair only), Class D (sheet metal ductwork) and Class E (refrigeration). It is treated here as the master level because Ark. Code §17-33-303(a) issues it to the individual who designs, installs or services HVACR systems, and that person becomes the 'designated license holder' responsible for the work and for registering employees. A new applicant with no licensing background must be 18, show two years of experience as an HVACR contractor or employee (Board-approved education may substitute) through notarized employer affidavits, and pass the open-book class exam administered by Prov ($80 computer-based, 70% to pass); the annual license fee is $200 for Class A, $150 for B, D and E and $100 for C, with $250,000 liability insurance and four hours of continuing education per year. The Board states it has no reciprocal agreements with any other state, but its rules direct it to approve, without examination, apprenticeship, education or training, any applicant holding a license in good standing from a jurisdiction whose HVACR licensing laws are 'substantially similar', meaning one that has adopted a national model mechanical code and uses a comprehensive exam created and proctored by a national examination agency. Under §17-33-104 a state licensee needs no city or county license.
