North Dakota to Kentucky: master HVAC technician license reciprocity

No credit· Start overVerified September 15, 2026· 12 sources

North Dakota does not issue a statewide master HVAC technician license, so there is nothing to transfer. Here is Kentucky'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.

Out-of-state master HVAC or mechanical contractor without a reciprocity agreement (examination with experience credit)

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

A master HVAC, mechanical or HVAC contractor licensee from a state without a Kentucky reciprocity agreement applies on Form HVAC 1 as a new applicant. KRS 198B.658(1)(c)2 accepts two years engaged as a master HVAC contractor 'or equivalent thereof' in a jurisdiction other than Kentucky when shown by verifiable documentation, so an out-of-state contractor does not need Kentucky journeyman time; 815 KAR 8:010 Section 5 lists a copy of a current out-of-state master HVAC contractor license or equivalent among the acceptable proofs (or documentation of the work where the state does not license), and one year of experience means at least 1,500 hours in a continuous twelve-month period. The applicant must pass the Master HVAC examination with at least 70%: it is a single open-book exam covering codes, standards and practices together with the law and regulation of the HVAC business, offered by Prov ($80) or by the department on Form HVAC-4 ($150); 815 KAR 8:010 Section 4(8) requires DHBC to recognize an equivalent examination on a showing that it covers the same material at the same level, and passing scores are valid for three years. The license issues only with a certificate of general liability insurance of at least $500,000 and property damage insurance of at least $300,000 from a Kentucky-licensed carrier naming DHBC as certificate holder (which a represented company may provide), the $250 twelve-month fee prorated by birth month ($145.83 to $375), and a passport photo; the application stays open one year.

Kentucky has no separate business-and-law exam for the master HVAC license; the law and regulation content is a section of the single Master HVAC exam, so examLawRequired is recorded as false. Acceptance of a previously passed out-of-state or national master mechanical exam under Section 4(8) is at the department's discretion and no list of recognized exams is published. Exam fee: Prov bulletin (2020) $80; department-administered exam per Form HVAC-4 and 815 KAR 8:010 $150.

Issued by Kentucky Department of Housing, Buildings and Construction (DHBC), Division of HVAC / Licensing Branch

Kentucky's highest person-held HVAC credential is the statewide Master HVAC Contractor license issued by the Department of Housing, Buildings and Construction (DHBC) to an individual who qualified by examination; the master supervises and is primarily responsible for all HVAC work of the company he or she represents (a company may carry the required insurance in its name), and only a master or journeyman may purchase the statewide HVAC permits required since 2011. A new applicant must be 18, a citizen or authorized resident alien, and have two years as a licensed journeyman under a master HVAC contractor, two years as a master HVAC contractor 'or equivalent' in Kentucky or any other jurisdiction, or two years as a licensed mechanical engineer; pass the open-book Master HVAC exam, which covers codes and practices plus the law and regulation of the HVAC business, with at least 70% (Prov $80, or the department's exam for $150 on Form HVAC-4); carry general liability insurance of $500,000 and property damage insurance of $300,000 (KRS 198B.668) naming DHBC as certificate holder; and file Form HVAC 1 with a $250 twelve-month fee prorated by birth month ($145.83 to $375). Licenses renew annually at $250 with continuing education and current insurance. KRS 198B.666 authorizes licensure by reciprocity for states with substantially equal requirements that reciprocate, and Form HVAC 1 has a reciprocity checkbox requiring a letter of good standing; DHBC publishes no HVAC partner list, but Ohio's OCILB documents an active Kentucky-Ohio HVAC and refrigeration agreement. Federal EPA Section 608 certification is required for refrigerant work but is not verified by DHBC.

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.
