Nebraska to Virginia: master HVAC technician license reciprocity

How local licensing works. Nebraska has no state HVAC license and no state mechanical board. The Contractor Registration Act (Neb. Rev. Stat. § 48-2104) requires every contractor to register with the Department of Labor before performing construction work ($40 per year from August 1, 2026, plus a workers' compensation certificate if there are employees); registration is not a license and involves no exam. Master and contractor licensing comes from each city's ordinance.

Omaha. The Master ACAD license (Omaha Municipal Code ch. 40, art. II) is the credential that lets a person contract for and pull permits for air conditioning and air distribution work. Applicants need eight or more years of verifiable experience installing ACAD systems, or four or more years employed by a licensed master after obtaining an Omaha (or equivalent) journeyman ACAD license (one year = 1,750 hours), must appear before the ACAD Board, and pass a Pearson Vue exam with 75% or greater. After passing they file a $10,000 surety bond and $300,000 liability insurance with the Planning Department. Fees: $81.00 application, $50 license plus $4.00 technology fee; renewal $160 plus $12.80 every two years (December 31 of odd years) with 8 hours of continuing education. Reciprocation: the board may waive the exam for a holder of a valid Bellevue, Nebraska or State of Iowa master ACAD contractor license with an exam score of 75% or greater (ACAD Reciprocation Application, $81.00). Sec. 40-40 of the code also allows licensees of comparable cities to apply without re-examination, but the city's page names only Bellevue and Iowa.

Lincoln. The Mechanical Master Contractor license requires holding a valid mechanical journeyman license for at least one year and passing the city master exam ($400 filing fee, given quarterly), which has four parts (ACCA Manual J, duct sizing, Lincoln Gas Code and Lincoln Adopted Amendments) plus the ICC National Standard Master Mechanical exam G29 taken at the applicant's cost. Annual registration is $350 (inactive master $50; a separate Refrigeration Master Contractor registration is $250) with 8 hours of continuing education, and the contractor must carry $500,000 per-occurrence general liability insurance naming the City of Lincoln as additional insured and register with the Department of Labor. Transfers: a holder of a valid contractor/master mechanical license obtained by examination in another state or municipality may take the Lincoln contractor exam without submitting additional qualifications; the exam is not waived.

Bellevue. Only a licensed mechanical master may contract for mechanical work in the city (Bellevue Municipal Code ch. 27, Division 2). Master applicants must submit a current journeyman license with its original issue date and state whether they have already passed the Thompson Prometric, ICC or Experior exam for the license applied for. A master arriving from another state should expect to sit the city exam (Lincoln) or present ICC National Standard Master Mechanical results where accepted, obtain the city's insurance and bond, license the business in each city where it will pull permits, and register with the Department of Labor. EPA Section 608 certification is federal and applies to anyone personally handling refrigerants.
