North Dakota to Arkansas: master HVAC technician license reciprocity

No credit· Start overVerified September 15, 2026· 6 sources

North Dakota does not issue a statewide master HVAC technician license, so there is nothing to transfer. Here is Arkansas's standard path for out-of-state applicants.

Your origin state does not issue a statewide license at this level, so there is no license to transfer. The destination's standard out-of-state path is shown; expect to meet it in full.

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)

Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.

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and proctored by a national examination agency or equivalent, provided the license is in good standing, has never been revoked for bad faith or a violation of law, rule or ethics, is not suspended or on probation, the applicant is competent in the field and pays the class license fee;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.

What you must already have

Your North Dakota license must be active and in good standing.
Origin license is 'substantially similar': the jurisdiction has adopted a national model mechanical code and uses a comprehensive examination created and proctored by a national examination agency or equivalent (rule §III(22)); otherwise two years of HVACR experience and the class exam are required
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. Expressed here as roughly 4,000 hours; the rule states it in years.

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.

Why North Dakota has nothing to transfer

North Dakota master HVAC technician

Licensed by cities and counties

Verified September 15, 2026· 16 sources

North Dakota issues no master HVAC, mechanical or refrigeration license and has no state mechanical board. The only state-level credential an HVAC contractor needs is the Secretary of State contractor license, a business license for any job over $4,000 (Class D up to $100,000 for $100, up to Class A over $500,000 for $450) that requires liability insurance and workers' compensation verification but no trade exam. The master-level credential is the city master HVAC/mechanical installer license: Fargo's Master Heating license (10,000 hours including 6,000 as a journeyman, exam, $125 per year, liability insurance naming the city), Bismarck's Class A Master HVAC Installer (3,400 hours as a licensed journeyman, exam with 80% to pass, $125 per year), Grand Forks' Master Mechanical Installer (exam with 80%, $170 per year, $5,000 city bond, state contractor license) and Minot's Master Heating/HVAC Installer (board exam, $130 per year). A master exam passed in one of the testing member cities is accepted by the other North Dakota licensing members through the state mechanical reciprocity program, but each city issues its own license. No city recognizes an out-of-state master or contractor license outright; Bismarck's ordinance counts journeyman experience licensed by any governmental jurisdiction toward master exam eligibility, so an out-of-state master generally qualifies to sit a city master exam on the strength of documented experience and then licenses city by city. EPA Section 608 certification applies federally.

How local licensing works in North Dakota

How local licensing works. North Dakota has no state mechanical board; master-level HVAC licenses are issued by cities under their own ordinances, and a master exam passed in a testing member city (Burleigh County, Bismarck, Fargo, Grand Forks, Minot, Mandan or Dickinson) is accepted by the licensing member cities (also Jamestown, Valley City, Wahpeton, West Fargo and Williston) under the North Dakota Mechanical Reciprocity Administrative Rules, which require at least two years of practical experience beyond the journeyman level; the Reciprocity Eligibility Certificate is not a license. Every contractor whose job exceeds $4,000 also needs the Secretary of State contractor license (Class A-D, $450/$300/$225/$100, liability insurance and WSI verification, no exam).

Fargo. Master Heating license: at least 6,000 hours of journeyman experience plus 4,000 hours of practical experience (10,000 total) verified by employer letters; open-book master mechanical and master fuel gas exams on the 2024 IMC and IFGC ($125 per appointment); license $125 per year expiring December 31, renewed with a certificate of liability insurance naming the City of Fargo. Work in non-owner-occupied buildings must be done by a licensed and insured mechanical contractor.

Bismarck. Class A Master HVAC Installer: two years (3,400 hours) as a licensed journeyman 'licensed by the City or some other governmental jurisdiction', or a master license from a reciprocal jurisdiction; exam on the 2021 IMC and IFGC, $125, 80% to pass, offered monthly; $35 application fee and $125 annual fee expiring December 31; four hours of continuing education per year; a master may qualify only one shop or business at a time; three years (5,300 hours) as a licensed journeyman are needed for a Certificate of Reciprocity to other cities. Legacy licensees who tested before July 1, 2017 may work in Bismarck without retesting.

Grand Forks. Master Mechanical Installer: ND state contractor license, $5,000 license and permit bond payable to the City, certificate of insurance, written mechanical exam with 80% to pass, $170 per year.

Minot. Master HVAC Installer (Master Heating): Heating & Air Conditioning Board exam ($75 per attempt) or a reciprocal license from an approved city with proof of the passed test; $130 initial and $130 annual fee; state contractor license required; annual renewal without re-examination, re-examination after a lapse.

Out-of-state holders. No reciprocity or endorsement for other states' master or contractor licenses was found in any of these cities or in the state reciprocity rules. The practical route is to document journeyman-level hours from the origin state, pass the master exam in one testing member city, obtain the Secretary of State contractor license, and then apply for the local master license (with the local bond or insurance) in each city where work will be done.
