Do I need a permit for hvac replacement or installation in Unincorporated Alleghany County?
Yes. In North Carolina, hvac replacement or installation generally requires a permit, and Unincorporated Alleghany County 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. Alleghany County's own permitting office is the Alleghany County Planning & Inspection office, reachable on 336-372-8974 at https://alleghanycounty-nc.gov/planning-inspection/. 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.
