Do I need a permit for hvac replacement or installation in Dunn?
Yes. In North Carolina, hvac replacement or installation generally requires a permit, and Dunn is no exception.
Across North Carolina, an HVAC changeout requires a mechanical permit and must be performed by a state-licensed heating contractor; it is not covered by the NCGS 160D-1110 minor-work exemption because it is mechanical work. Any new electrical circuit or gas line associated with the equipment requires the corresponding trade permit. Harnett County's own permitting office is the Harnett County Inspections office, reachable on 910-893-7525 at https://www.harnett.org/permits/. Its online permit portal is https://permits.harnett.org/etrakit/. It issues permits for the unincorporated county. If your city does not run its own building department, this is the office that will handle the job, and that is more common in North Carolina than most states: the county is often the building authority even inside city limits, with the city handling only zoning. A change-out is normally a mechanical permit, and gas fired equipment usually adds a second permit and a pressure test. Dunn permits are handled by the Dunn Planning and Inspections office, reachable on 910-230-3505 at https://www.cityofdunn.org/planning-inspections/. This split matters more in North Carolina than in most states: the county is often the building authority even inside city limits, with the city handling only zoning. Confirm whether Dunn or Harnett County issues the building permit for your address before you apply.
