HVAC licenses in Nebraska

There is no statewide HVAC contractor license that we could find; cities or counties license HVAC work.

Local rules: We could not find a statewide HVAC or mechanical contractor license in Nebraska. What the state does have is the Contractor Registration Act (Neb. Rev. Stat. 48-2101 to 48-2117), run by the Nebraska Department of Labor: contractors and subcontractors who work on real property other than their own must register each year (the fee rises to $40 on August 1, 2026), and those with one or more employees must file a workers' compensation certificate. This is a registration, not a trade license; the Act says it is not the Legislature's intent to endorse the quality or performance of any contractor (48-2102), and people working on their own property or earning less than $5,000 a year from construction are not contractors under it (48-2104). Separately, the State Electrical Division offers special electrician licenses limited to air conditioning and refrigeration systems (with an HVAC specialty exam); under the State Electrical Board rules these license holders cannot do any wiring on the line side of the disconnect. Trade licensing for the HVAC work itself is set by cities. The City of Lincoln registers mechanical trades under Chapter 25 of the Lincoln Municipal Code: Mechanical Master Contractor ($350 a year), Inactive Master, Journeyman and Apprentice, plus a Refrigeration-Mechanical Master Contractor ($250 a year) and fireplace categories; new journeymen and master contractors must pass exams, masters need 8 hours and journeymen 4 hours of continuing education to renew, and contractors pulling permits must file a certificate of liability insurance naming the city as additional insured. Lincoln lets a homeowner pull a mechanical permit for the single-family home they live in. We could not read the City of Omaha licensing pages for mechanical or air conditioning contractors (the site returned access errors), so we could not confirm Omaha's license names or requirements, and rules in other Nebraska cities were not checked.

Check the company on the Nebraska Department of Labor contractor registration search (dol.nebraska.gov/conreg/Search), then ask for the mechanical license or registration issued by your city (in Lincoln, a Mechanical Master Contractor registration) and confirm it and the permit with your city's building department.

Federal rule: in every state, technicians who handle refrigerant must hold EPA Section 608 certification, whatever the state or city requires.

We could not confirm every detail from Nebraska’s own sources, so treat this as a starting point and check with the agency.

HVAC licenses in Iowa

HVAC contractors are licensed by the state.

Who licenses: Iowa Plumbing and Mechanical Systems Board (PMSB), Iowa Department of Inspections, Appeals, and Licensing (DIAL)

License types: Contractor License, Master License, Journey Level License, Apprentice License, Service Technician HVAC Specialty License.

Companies: Under Iowa Code 105.10, a person may not operate as a contractor or install or repair plumbing, mechanical, HVAC, refrigeration, sheet metal or hydronic systems without a license. The Board's contractor license is required of anyone providing those services on a contractual basis. DIAL lists these requirements for it: a permanent place of business, a valid unemployment insurance number, $500,000 minimum public liability insurance, a $5,000 minimum surety bond, and at least one active master licensee for each discipline in which the company works. Section 105.11 exempts an owner doing work on their own principal residence if it is an existing single-family-sized dwelling (or farm property) and not commercial or industrial work.

Local rules: Iowa Code 105.17 says the state licensing provisions supersede and preempt the plumbing, mechanical, HVAC-refrigeration, sheet metal and hydronic licensing provisions of all governmental subdivisions, so cities such as Des Moines cannot add their own HVAC licenses. Cities and counties may still charge permit and inspection fees (105.17(2)), so a local permit may still be required.

Check a license: ia-plb.my.site.com

Search the contractor on the state professional license search and confirm an active contractor license covering HVAC or mechanical work, and ask who the master of record is for the job.

Federal rule: in every state, technicians who handle refrigerant must hold EPA Section 608 certification, whatever the state or city requires.

Questions to ask

Ask every company the same questions: license number, insurance, EPA refrigerant certification, a written itemized estimate, a load calculation for new equipment, after-hours rates, who pulls the permit, and the warranty. All eight questions.
