North Dakota to Idaho: master HVAC technician license reciprocity

No credit· Start overVerified September 15, 2026· 9 sources

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

Universal licensure for out-of-state HVAC contractors (all states)

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

With no reciprocity agreements, every out-of-state HVAC contractor or master is treated the same. Idaho Code 67-9409 obliges the HVAC board to license a person who holds a current, valid and unrestricted license in another state and demonstrates competency, on the standard application, fees and background checks, but lets the board require all or part of its examination; the board's rules require every contractor applicant to pass the board-designated exam and post a $2,000 bond, and DOPL publishes no HVAC-specific endorsement procedure. The realistic path is therefore the standard contractor application ($35), the PSI contractor exam ($75), the $2,000 compliance bond and the $225 license fee, with the out-of-state license and experience submitted as supporting evidence of competency.

Idaho's contractor exam covers business and law material (the DOPL Contractors' Business and Law Reference Manual is the allowed reference), so it is recorded as the trade exam rather than a separate law exam. Idaho Code 54-5013 sets a 24-month certificate term while DOPL's fee table shows a 3-year term for journeyman and contractor licenses; the fee table is the current practice. Whether the board waives any part of the exam under 67-9409 was not confirmed from an official page.

How Idaho licenses master HVAC technicians

Idaho master HVAC technician · “HVAC Contractor”

Statewide license

Verified September 15, 2026· 9 sources

Issued by Idaho Heating, Ventilation and Air Conditioning Board (Division of Occupational and Professional Licenses)

Idaho has no master HVAC title; its highest credential is the HVAC Contractor certificate of competency, which is issued as a card in the name of the individual who passes the board's contractor examination and is therefore mapped here to the master level (an HVAC business must hold or employ a certificate holder, and Specialty Contractor and Limited Heating Specialty Contractor certificates cover gas piping, hearth appliances and oil furnaces). The applicant pays a $35 application fee, passes the PSI-administered HVAC contractor exam ($75, using the DOPL Contractors' Business and Law Reference Manual as a reference), provides a $2,000 compliance bond, and pays the $225 license fee; the certificate renews for $150 every three years. Idaho's HVAC board states that it has no reciprocal licensing agreement. A contractor licensed in another state may apply under Idaho's universal licensure statute (Idaho Code 67-9409), which requires the board to license a person with a current, unrestricted out-of-state license who demonstrates competency, but allows it to require the Idaho exam; since DOPL publishes no separate procedure for HVAC, applicants should expect to take the contractor exam. EPA Section 608 certification is required nationwide to handle refrigerants.

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.
