Nebraska to Oklahoma: master HVAC technician license reciprocity
Nebraska does not issue a statewide master HVAC technician license, so there is nothing to transfer. Here is Oklahoma'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.
Out-of-state master HVAC or mechanical contractor (all states; no published reciprocity partners)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
No state has a published mechanical contractor reciprocity agreement with Oklahoma, so every out-of-state master HVAC technician or mechanical contractor uses the same route. Under OAC 158:50-9-4.1 an applicant from a state without a reciprocal agreement may request exam equivalency; if the Board has previously approved that jurisdiction's exam, the technical trade portion of the Oklahoma contractor exam is waived on a certified letter showing current good standing, the license category, a 70%+ exam score and no pending discipline, but the Mechanical Business and Law portion must still be passed. CIB does not publish the approved jurisdictions. Otherwise the applicant files the Application for Mechanical Examination with notarized experience affidavits and a copy of the out-of-state license, documents four years of verifiable experience in the category, pays $330, and must pass both portions of the contractor exam through PSI within three years of approval. To activate the license the contractor files a $5,000 bond and $50,000 general liability insurance with CIB; a contractor employed by a single business or public entity may instead file that employer's affidavit. Federal EPA Section 608 certification is required separately to handle refrigerants.
Even where a written contractor reciprocity agreement exists, OAC 158:50-9-6(e) grants only a journeyman license by reciprocity and requires the Oklahoma Business and Law portion before the contractor license issues; since no mechanical agreement is published, no agreement rows are recorded. Some third-party sites claim contractor reciprocity with Texas, Arkansas, Kansas or New Mexico, but no CIB page lists such an agreement.

How Oklahoma licenses master HVAC technicians
Oklahoma master HVAC technician · “Mechanical Contractor (HVAC/R Unlimited or Limited)”
Statewide license
Issued by Oklahoma Construction Industries Board (CIB), Mechanical Division
Oklahoma has no 'master HVAC' license; its highest person-held HVAC credential is the Mechanical Contractor license, which CIB issues to an individual who passes the two-part contractor exam (technical trade and Mechanical Business and Law, 70% each, $92 per portion). This site maps the HVAC/R Unlimited (or Limited) Mechanical Contractor license to the master level. An applicant needs the journeyman qualifications plus one additional year, so four years (8,000 hours) of verifiable experience in the category, and pays $330 ($30 application plus $300 initial license). After passing, an inactive license issues until the contractor files a $5,000 corporate surety bond and a $50,000 commercial general liability certificate with CIB; an inactive contractor may work as a journeyman. Every mechanical firm must have a licensed contractor associated with and responsible for its work. OAC 158:50-9-6 lets CIB sign contractor reciprocity agreements, under which the applicant would still have to pass the Business and Law portion, but CIB publishes no mechanical partner states. Licenses renew annually ($200) with six hours of continuing education every 36 months.
Why Nebraska has nothing to transfer
Nebraska master HVAC technician
Licensed by cities and counties
Nebraska does not issue a statewide master HVAC or mechanical contractor license; the state only requires contracting businesses to register with the Department of Labor under the Contractor Registration Act ($40 per year, no exam), and it licenses no construction trade at the state level except electricians. The master-level HVAC credential exists only at the city level: Omaha's Master Air Conditioning/Air Distribution (ACAD) contractor license, Lincoln's Mechanical Master Contractor license, Bellevue's master mechanical license and Grand Island's master mechanical license, each requiring the city's exam (Lincoln and Bellevue reference the ICC National Standard Master Mechanical exam) plus liability insurance and, in Omaha, a bond. An out-of-state master HVAC license carries no state-level recognition; Omaha waives its exam only for Bellevue and State of Iowa master ACAD licensees, and Lincoln allows any out-of-state master licensed by exam to sit its contractor exam without further qualifications. A contractor working in several cities must be licensed in each and registered with the Department of Labor.
How local licensing works in Nebraska
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.
