ConditionalNorth Dakota Secretary of State — Contrac…
No state board licenses heating, ventilation, and air-conditioning work in North Dakota. A 2024 Legislative Council report on occupational licensure quotes the state's plumbing, heating, and mechanical contractors' association warning that there is no statewide licensure process for mechanical/HVAC contractors outside municipalities. No 2025 bill creating one was found.
HVAC businesses still need the Secretary of State contractor license (Class A–D) on any job over $4,000, with liability insurance and WSI coverage. The electrical side of an installation — wiring for heat or power — requires a State Electrical Board licensee, and technicians who handle refrigerants need federal EPA Section 608 certification. Cities may license mechanical contractors locally.
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
With no state HVAC license, mechanical licensing and permitting are local. The state contractor license applies statewide on jobs over $4,000, and the electrical portion is under State Electrical Board jurisdiction and inspection (N.D.C.C. §§ 43-09-21, 43-09-22).

North Dakota licenses electricians and plumbers but not HVAC or mechanical contractors; the Legislature's 2024 licensure report records the industry's concern about that gap.
Wiring for electric heat or power, including equipment circuits, needs a State Electrical Board licensee at any job size.

Acting as a contractor without a license is a crime, and the Secretary of State may also assess a civil penalty that must be paid before a license issues.
