How to Start an HVAC Business in Nebraska (2026)

Last updated: February 25, 2026

Nebraska does not issue a statewide HVAC contractor license – but that does not mean HVAC contractors can skip licensing entirely. Technicians who handle refrigerants must hold federal EPA Section 608 certification, and contractors operating in Omaha or Lincoln must obtain a local mechanical contractor license from the respective city. All contractors with employees must register with the Nebraska Department of Labor under the Contractor Registration Act. This guide explains every requirement using official sources.

How to Start an HVAC Business in Nebraska (Step by Step)

Step 1: Form Your Business Entity and Get an EIN

An LLC is the most common structure for Nebraska HVAC contractors. File a Certificate of Organization with the Nebraska Secretary of State online at nebraska.gov/apps-sos-edocs. Fee: $100 online (plus $2 processing fee).

Nebraska’s publication requirement: After filing your LLC, publish a notice of organization in a legal newspaper in the county of your principal office. File an Affidavit of Publication with the SOS after publication. This is a legal requirement.

Apply for a free federal EIN at irs.gov. Required before opening a business bank account and registering for state taxes.

Step 2: Get EPA Section 608 Certification

Federal law (Clean Air Act Section 608) requires that any technician who purchases, handles, installs, or recovers refrigerants must hold an EPA Section 608 certification. This applies regardless of which state you work in.

• Certification types: Type I (small appliances), Type II (high-pressure), Type III (low-pressure), and Universal (all types). Most HVAC technicians pursue Universal certification.
• How to get certified: Pass a proctored exam through an EPA-approved organization such as ESCO Group, NATE, or HVAC Excellence. Exam fees range from $20-$60 per certification type.
• No expiration: EPA 608 certifications do not expire and are valid in all 50 states. Keep your original certificate on file.
• More info: epa.gov/section608

Step 3: Register as a Contractor with the Nebraska Department of Labor

Under the Nebraska Contractor Registration Act, all contractors and subcontractors operating in Nebraska with one or more employees must register with the Nebraska Department of Labor (NDOL).

• Who must register: Any HVAC contractor operating in Nebraska who has employees.
• How to register: Submit a registration through the NDOL portal at dol.nebraska.gov/conreg. Registration is free.
• What you need: You must provide a current workers’ compensation Certificate of Insurance (ACORD 25 form) with the Nebraska Department of Labor listed as the certificate holder.
• More info: dol.nebraska.gov – Contractor Registration

Step 4: Obtain Local Mechanical Contractor License (Omaha and Lincoln)

Nebraska does not issue a statewide HVAC contractor license. However, in counties with a population of 100,000 or more (Douglas County/Omaha and Lancaster County/Lincoln), contractors must obtain a local mechanical or HVAC contractor license.

Omaha (Douglas County)

• The City of Omaha Planning Department issues Air Conditioning/Air Distribution (ACAD) contractor licenses.
• Local license fee: approximately $100 + $8 technology fee (initial and renewal).
• Requires proof of $1,000,000 general liability insurance and $500,000 bodily injury insurance.
• A $5,000 surety bond is required.
• Contact: City of Omaha Planning Department, Permits and Inspections Division. Phone: (402) 444-5350 ext. 2122. More info: permits.cityofomaha.org

Lincoln (Lancaster County)

• The City of Lincoln Department of Building and Safety issues mechanical contractor licenses.
• Contact the Lincoln Building and Safety office for current application requirements and fees.
• More info: lincoln.ne.gov/city/build

Other Nebraska cities

Smaller Nebraska cities may have their own permit or registration requirements for HVAC work. Always check with the local building or permit office before starting work in a new jurisdiction.

Step 5: Register for Nebraska Taxes

HVAC contractors in Nebraska must register for the following taxes:

• Sales Tax: The sale of HVAC equipment and parts is taxable in Nebraska (5.5% state rate plus local rates). Register for a free Nebraska Sales Tax Permit at revenue.nebraska.gov.
• Income Tax Withholding and UI: If you have employees, register for state withholding and unemployment insurance through the NeDOR and NEworks portals.

Step 6: Get Required Insurance

HVAC is among the most insurance-intensive trades. You need:

• Workers’ Compensation Insurance: Required for any business with one or more employees in Nebraska. HVAC has higher-than-average workers’ comp rates due to the physical nature of the work. Purchase from a licensed Nebraska insurer; see newcc.gov.
• General Liability Insurance: Omaha’s local licensing requires at least $1,000,000 per occurrence / $500,000 bodily injury. Most commercial contracts require similar coverage. Typical annual cost: $1,800-$3,600 for small HVAC operations.
• Surety Bond: Required for Omaha local licensing ($5,000). May also be required by commercial clients or local permits in other cities.

Frequently Asked Questions

Does Nebraska require an HVAC contractor license?

Nebraska does not issue a statewide HVAC contractor license. However, technicians who handle refrigerants must hold federal EPA Section 608 certification (required in all 50 states). Additionally, contractors working in Omaha (Douglas County) must obtain a City of Omaha Air Conditioning/Air Distribution (ACAD) contractor license, and contractors working in Lincoln must obtain a local mechanical contractor license from the City of Lincoln. Always check local requirements before starting work in any Nebraska city.

What is EPA Section 608 certification and do I need it?

EPA Section 608 certification is a federal requirement under the Clean Air Act for any technician who purchases, handles, or recovers refrigerants. It is not specific to Nebraska – it applies in all 50 states. Most HVAC technicians get Universal certification, which covers all refrigerant types. Take a proctored exam through an EPA-approved provider (ESCO, NATE, etc.) for $20-$60 per exam type. Universal certification typically costs $60-$120. The certification never expires and does not require renewal.

What does Nebraska contractor registration require?

Under the Nebraska Contractor Registration Act, all contractors with one or more employees must register with the Nebraska Department of Labor (NDOL) for free at dol.nebraska.gov/conreg. You must provide a current workers’ compensation Certificate of Insurance (ACORD 25) with NDOL listed as the certificate holder. This is separate from any local city licensing requirements.

What insurance does an HVAC contractor need in Nebraska?

Nebraska workers’ comp law requires coverage for any business with one or more employees. For HVAC work in Omaha, the local ACAD license requires at least $1,000,000 general liability insurance, $500,000 bodily injury insurance, and a $5,000 surety bond. Most commercial clients and general contractors also require similar coverage. Typical annual cost for a small HVAC business: $1,800-$3,600 for GL, plus workers’ comp rated on payroll.

Do I need a separate license to work in both Omaha and Lincoln?

Yes. Omaha and Lincoln issue separate local mechanical contractor licenses through their respective city departments (the City of Omaha Planning Department and the City of Lincoln Department of Building and Safety). If you plan to work in both cities, you will need both local licenses plus your EPA 608 certification and NDOL contractor registration. Rural Nebraska counties generally do not require a separate local license beyond the NDOL registration.

Can I work as an HVAC technician in Nebraska without forming an LLC?

Yes – you can operate as a sole proprietor. However, HVAC work carries significant liability risk (property damage, personal injury). An LLC provides personal asset protection and is strongly recommended. If you operate under any name other than your own legal name as a sole proprietor, you must register a Trade Name with the Nebraska Secretary of State for $100 (plus required newspaper publication).
