You're licensed in North Dakota as an HVAC technician — the next 30 days

Most of the steps below are required before your first paid job; the order is the order the state and its counties will ask for them.

  1. Form the business and get an EIN.

    The North Dakota Secretary of State issues the Class A / B / C / D Contractor (via Secretary of State); the business that invoices North Dakota customers is a separate decision. A sole proprietorship is the default, an LLC keeps business liability off your personal assets, and either needs an EIN before the first payroll. Settle it before the license number goes on an estimate.

  2. Carry the insurance the license requires.

    North Dakota requires general liability insurance for this license. Workers' compensation is required once you hire employees. Contractor insurance requirements→

  3. Register locally.

    North Dakota does not require a separate HVAC trade license. HVAC contractors need the general Secretary of State contractor license for projects over $4,000. EPA 608 certification is required for refrigerant handling. Some cities may have additional requirements.

  4. Set up quoting, scheduling and invoicing before the first call.

    Your first customers will ask for a written estimate and expect to pay by card on site. Most one-truck HVAC technician businesses run that on field-service software; Housecall Pro is the one we link because it is built for this size of company and this link carries 20% off your first 12 months.

  5. Keep the license.

    Renewal is every year (due March 1) at $30.
