How to Start an HVAC Business in Nebraska

HVAC work pays well and comes with built-in repeat business: every system needs seasonal maintenance and eventually a replacement. Most owners start as experienced technicians. Licensing is set by states and cities, while refrigerant handling falls under federal EPA rules.

Nebraska requirements for this business

  • All contractors and subcontractors doing business in Nebraska must register with the Nebraska Department of Labor; the annual fee is $40.00 effective August 1, 2026, and registration does not ensure quality of work. [source]
  • Registered contractors with one or more employees must keep a current workers' compensation certificate (ACORD 25) on file with the Department of Labor listed as certificate holder, or they are removed from the registered list. [source]
  • Nebraska's State Electrical Act lists air conditioning and refrigeration installation among the limited classes of work covered by a special electrician license. [source]
  • Cleaning furnaces, air conditioners, heat pumps and duct work is a taxable building cleaning service in Nebraska; on HVAC repairs, Option 1 contractors collect tax on materials but not on separately stated labor. [source]

Statewide steps for every Nebraska business — forming an LLC or registering a business name with the Nebraska Secretary of State — are on our state licensing directory.

FirstBizGuide is not a government agency: any license or registration fees are paid directly to the agency named in each source. These are the Nebraska facts we have verified so far, not a complete list. City and county rules vary — check with your local government before opening.

  • Vacuum pump and micron gauge
  • Leak detector, multimeter and clamp meter
  • Brazing torch kit, tubing cutters and flaring tools
  • Service van with parts shelving

Licenses and registration

  • If you form an LLC or corporation, register it with your state; if you use a business name other than your own, file a trade name (DBA) where your state requires it (in some states that's the county).
  • Most states or cities license HVAC or mechanical contractors, often requiring documented experience and an exam; check your state contractor board and your city building department.
  • EPA requires technicians who maintain, service, repair or dispose of equipment that could release ozone-depleting refrigerants to be Section 608 certified by passing an EPA-approved test from an EPA-approved certifying organization; the credentials do not expire. [source]
  • Under EPA's refrigerant sales restriction, Section 608 certified technicians, and employers who give the wholesaler written proof that they employ at least one certified technician, can generally buy any type of ozone-depleting or substitute refrigerant. [source]
  • Installing or replacing equipment usually requires a permit and inspection from the local building department.
  • Firms paid for work that disturbs paint in homes and child-occupied facilities built before 1978 must be certified under the EPA Renovation, Repair and Painting (RRP) rule, unless an exemption such as minor repair applies; EPA says window replacement and demolition of painted surfaces are always covered. [source]
  • Some states run their own lead-based paint (RRP) program instead of EPA; if yours does, certify with the state. [source]
  • Commercial clients and general contractors often ask for a certificate of insurance, a W-9 and proof of license.
  • Get a free Employer Identification Number (EIN) from the IRS if you will hire employees or form an LLC or corporation. Beware of sites that charge for this. [source]
  • To find your state's business registration office, use the SBA's state-by-state registration lookup. [source]

Insurance to consider

  • General liability (water damage, fire and property damage claims)
  • Commercial auto for service vans
  • Tools and equipment (inland marine) coverage
  • Workers' compensation once you hire
  • Contractor license bond if your state or city requires one

Get quotes from several carriers or an independent agent; coverage needs depend on your contracts, state and staff.

Financing options

  • SBA 7(a) loans — the SBA's main guaranteed loan program, made through participating lenders. [source]
  • SBA Microloans — smaller loans delivered through nonprofit intermediary lenders. [source]
  • SBA Lender Match — a free tool that connects you with interested SBA lenders. [source]
  • Free counseling from your local SBDC or SCORE chapter can help you build the business plan lenders ask for. [source]
