Nebraska HVAC contractor license: state vs. city

Nebraska does not issue a statewide HVAC license. Instead, state law lets cities with air‑conditioning/air‑distribution boards require proof of competency and licensing. You must always register with NDOL to operate and then satisfy the city’s license rules where you work. (Neb. Rev. Stat. §18‑2307; NDOL Contractor Registration).

Lincoln mechanical/HVAC contractor license (what to expect)

Lincoln requires passing city exams (with an ICC G31 component for journeyman), then paying exact fees: $400 exam (master), $50 exam (journeyman), and annual registration $350 (master) or $25 (journeyman). For renewal, submit CEUs (8/4 hours) and maintain GL insurance naming the City as additional insured. (exam process; fees & CEUs; insurance).

Omaha ACAD (Air Conditioning/Air Distribution) licensing

Omaha’s ACAD Board oversees HVAC licensing. Masters must pass a city‑accepted exam, carry GL insurance, and file a surety bond of at least $10,000 before license issuance; renew through the permits portal. Check the city’s licensing page for current fee and insurance minimums and board procedures. (Omaha Licensing; Mun. Code §40‑32 bond (public notice)).

Permits and inspections

After you’re licensed locally, you’ll pull mechanical permits for installs/alterations and schedule inspections per city code. Lincoln and Omaha both require permits before work begins, and they enforce their adopted mechanical codes. (Lincoln Mechanical Code; Omaha Ch. 43 referencing Mechanical Code Ch. 40).
