How North Dakota licenses HVAC work
Licensing is split between the state and local governments.
Who licenses: North Dakota Secretary of State (Contractor Licensing)
License types: Class A Contractor License, Class B Contractor License, Class C Contractor License, Class D Contractor License.
Companies: North Dakota has no HVAC-specific state license; under N.D.C.C. 43-07-02 any contractor whose job cost, value or price exceeds $4,000 must hold a Secretary of State contractor license (Class A-D by project size), and the statute does not name HVAC specifically. Electrical and plumbing work are licensed separately by their own state boards.
Local rules: The state pages we read do not address HVAC trade licensing; the City of Fargo issues its own Journeyman and Master mechanical/HVAC licenses after an exam (apply via permits.fargond.gov), and other cities may have similar rules that we did not verify.
Check a license: firststop.sos.nd.gov
Search the contractor on the Secretary of State FirstStop portal to confirm an active contractor license, and for jobs in Fargo also ask for the city mechanical license and permit.
Federal rule: in every state, technicians who handle refrigerant must hold EPA Section 608 certification, whatever the state or city requires.

Before you hire
Ask for the license number and check it on the official lookup where one exists. Ask for proof of insurance and a written, itemized estimate, and ask who pulls the permit if the job needs one – a new furnace, heat pump or air conditioner usually does.
