Form the business and get an EIN.
The NC State Board of Examiners of Plumbing, Heating, and Fire Sprinkler Contractors issues the Heating Contractor (H-1, H-2, or H-3); the business that invoices North Carolina 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.
Post the bond.
North Carolina requires a $5,000 surety bond. Minimum $5,000 surety bond. Local jurisdictions may require additional bonds. How contractor bonds work→
Carry the insurance the license requires.
North Carolina requires general liability insurance for this license. GL required: $300,000/$600,000 minimum. Workers comp for 3+ employees. Contractor insurance requirements→
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.
