How to Start an HVAC Business in Nebraska: No State License, Omaha ACAD Master Fees, Lincoln $350 Mechanical Registration and the State Electrical HVAC License

If you searched for a nebraska hvac license or hvac license nebraska, you probably expected one state credential that covers heating and cooling contractors. Nebraska does not work that way. No statewide HVAC contractor or technician license is administered by the State Electrical Division or the Nebraska Department of Labor. HVAC is regulated in layers instead: a state electrical license for the wiring side, a federal refrigerant certification, and local licenses or registrations set by the city or village where you work.

This guide walks through the steps to set up an HVAC business in Nebraska, using the fees and timelines that official sources currently show. Some local figures come from city pages archived on different dates, so confirm every number with the agency before you pay.

What You Need Before You Start

Gather these items before you file anything:

• A written scope of work that states whether you will install, service or both, and whether your crews will do electrical wiring
• A company name that meets Nebraska's LLC naming rules
• A registered agent with a physical Nebraska office
• A federal Employer Identification Number (EIN) from the IRS
• Money for the $100 Certificate of Organization filing fee and a newspaper notice (the newspaper cost varies, so request a quote)
• General liability insurance, meeting the $300,000 requirement if you work in Omaha
• A $10,000 bond if you pursue Omaha's ACAD master license
• EPA Section 608 certification for every technician who handles refrigerant
• A shop or office address that fits local zoning

Step 1: Define Your Work and Check Whether NDOL Registration Applies

Your scope of work determines which agencies matter. The Nebraska Department of Labor (NDOL) runs a contractor registration for construction work. It applies to construction work over $5,000 a year, and the fee is $40 starting August 1, 2026. Whether your residential service and installation work falls under that threshold is a question for NDOL, not a guess. Ask them in writing and keep the answer in your file.

If you plan to hire employees, you will also register with NDOL for unemployment tax. Confirm the timing with NDOL before your first payroll.

Step 2: Form Your Entity

Most owner-operators choose a limited liability company (LLC). The formation document is a Certificate of Organization filed with the Nebraska Secretary of State, Business Services Division. The filing fee is $100. You can file through the Corporate & Business Document eDelivery portal at nebraska.gov/apps-sos-edocs or by mail. The Secretary of State does not publish a standard processing time, and no expedited service fee exists for entity filings, so build in a buffer before you need the company to sign contracts or open accounts.

Your name must include the words limited liability company or limited company, or an abbreviation such as LLC, L.L.C., LC or L.C. Limited may be abbreviated as Ltd. and company as Co. The name cannot be the same as or deceptively similar to a name already on record. Search the state business database at the Secretary of State search page before you file. If you need time, a name reservation holds the name for 120 days for $30.

Nebraska calls the agent a registered agent. Every LLC must keep a Nebraska office and an agent for service of process. The agent can be an individual who resides in Nebraska or an entity authorized to transact business there, and the agent's office must match the registered office. If the agent lapses, the company can be administratively dissolved. Changing the agent or office costs $25 online or $30 on paper.

New LLCs must also publish a notice in a legal newspaper for three successive weeks, then file proof of publication with the Secretary of State. Put this on your calendar the day you file, because the proof is a separate step that many new owners forget.

Step 3: Register for Taxes and Employer Accounts

Nebraska has no general state business license and no county business license. Registration follows your activity:

• Nebraska ID with the Department of Revenue. Register through the Nebraska Department of Revenue site, or use the new business registration page.
• Sales and use tax permit. You need one if you make retail sales, rent or lease tangible personal property, or provide taxable services. The state sales tax rate is 5.5%. Whether a particular install, repair or parts sale is taxable depends on the transaction, so confirm the treatment with the Department of Revenue or a CPA.
• Income tax withholding certificate. Required if you have employees.
• NDOL unemployment tax account. Required once you have employees, as noted in Step 1.

Tax treatment depends on how the LLC is classified. A pass-through LLC reports income on the members' Nebraska individual returns, where 2026 rates run from 2.46% to 4.55%. An LLC taxed as a corporation pays the 4.55% Nebraska corporate income tax for tax years beginning on or after January 1, 2026. Nebraska imposes no franchise tax and no occupation tax on LLCs.

Step 4: Register a Trade Name if You Operate Under Another Name

If your LLC is Prairie Air Systems LLC but your trucks say Cornhusker Comfort Heating, you need a trade name registration. Trade names are registered statewide with the Secretary of State, not county by county. The application costs $100 online through eDelivery or $110 in office or by mail. A separate newspaper publication is required, though the proof of publication carries no fee. Registration lasts 10 years, and renewal costs $110. Use the Application for Registration of Trade Name form.

Step 5: Get the State Electrical HVAC License for the Wiring Side

The State Electrical Division licenses electricians, and it issues a Heating, AC and Refrigeration electrical license. This license covers the electrical side of HVAC work, not the mechanical side. The 2025 to 2026 schedule lists $37.50 per year of the two-year license period. Confirm the total due with the State Electrical Division when you apply. The license requires an in-office specialty exam, so schedule it early. Licenses expire December 31 of even-numbered years.

If your technicians will make electrical connections on installs or service calls, ask the State Electrical Division which of that work requires this license before you assign jobs. Guessing here is one of the most expensive mistakes a new contractor can make.

Step 6: Get EPA Section 608 Certification

Handling refrigerant requires EPA Section 608 certification under federal rules. Nebraska does not issue this credential, and it is not a state license. Each technician who opens, recovers or charges refrigerant needs the certification that matches the equipment they work on. Keep copies of every technician's card in your job files and in your vehicle.

Step 7: Apply for Your Local Mechanical License

This is where HVAC work is actually regulated. Nebraska has 93 counties and 528 municipalities (cities and villages), and the rules differ from place to place. Check the city or village where each job sits before you quote it.

Omaha: ACAD Master License

The Omaha ACAD master license carries an initial fee of $50 plus a $4 technology fee. Renewal costs $160 plus $12.80, and it requires 8 hours of continuing education. You must carry $300,000 in insurance and a $10,000 bond. Licenses expire December 31 of odd-numbered years. The Omaha page we reviewed was archived November 22, 2024, so confirm the current fee schedule with the City of Omaha before you apply.

Lincoln: Mechanical Registration

Lincoln uses a mechanical registration system. The city page we reviewed was archived April 23, 2026, and it lists these annual fees:

• Master contractor: $350 per year
• Journeyman: $25 per year
• Apprentice: $15 per year
• Refrigeration master: $250 per year

Renewals run October 1 to December 31. Exams come before registration. Continuing education is 8 hours for masters and 4 hours for journeymen. Confirm the current figures with the City of Lincoln before you budget.

Everywhere Else

Outside Omaha and Lincoln, check the rules of the city or village where the job is located. Gas piping and plumbing connections may fall under a separate plumbing license, and plumbers are licensed by the city or village nearest the job. Ask the local building office which mechanical and plumbing permits apply before you sign a contract in that jurisdiction.

Step 8: Set Up Insurance, Bonding and Zoning

General liability insurance is the baseline for almost every HVAC contractor, and Omaha sets a $300,000 minimum. If you hire employees, confirm your workers' compensation obligations with NDOL. Bonding requirements depend on the license you hold, so the $10,000 Omaha bond applies only to that license.

City and county zoning control where you can operate a shop, store equipment and park work vehicles. Confirm the address allows your use before you sign a lease. Some cities also levy city sales taxes and city occupation taxes, so ask the city clerk whether either applies to your business.

Step 9: Calendar Your Recurring Filings

Nebraska's recurring obligations are easy to miss because they come in odd and even years. Add these dates to your calendar as soon as your entity is formed:

• LLC biennial report: Filed in odd-numbered years between January 1 and April 1. The fee is $25 electronically or $30 on paper. The LLC becomes delinquent after June 16, and administrative dissolution follows.
• Corporation biennial report and occupation tax: Due March 1 of even-numbered years, delinquent after April 15. The $26 figure is the statutory minimum when paid-up capital stock does not exceed $10,000.
• State Electrical HVAC license: Expires December 31 of even-numbered years.
• Omaha ACAD master license: Expires December 31 of odd-numbered years.
• Lincoln registrations: Renew October 1 to December 31.
• Trade name: Renew every 10 years for $110.

Tips and Common Mistakes to Avoid

• Searching for a statewide HVAC license. It does not exist. Your credentials come from the state electrical side, federal refrigerant rules and local jurisdictions.
• Skipping the newspaper notice. Publication for three successive weeks plus the proof filing is required for new LLCs.
• Letting the registered agent lapse. A lapse can lead to administrative dissolution, which can disrupt contracts, bank accounts and permits.
• Trusting old fee pages. Both the Omaha and Lincoln figures above come from archived pages. Call or check the city before you apply.
• Working in Omaha or Lincoln before you hold the local license. Start the local application early, since exams and insurance certificates can take time.
• Assuming NDOL registration does not apply. Get NDOL's answer in writing for your specific work.
• Treating the state electrical license as optional. If your crews make electrical connections, confirm the requirement before the first job.

What to Expect

A clean, complete compliance file may help you move faster on permits, insurance quotes and commercial vendor onboarding. Many owners find that handling the paperwork in order, from entity to registrations to local licenses, reduces the back-and-forth with city offices. Results depend on your market, your scope of work and each agency's processing time, and nothing in this guide guarantees approval, revenue or a specific timeline.
