Do I need a permit for hvac replacement or installation in Greensboro?
Yes. In North Carolina, hvac replacement or installation generally requires a permit, and Greensboro 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. Greensboro requires a separate mechanical permit for heating and cooling equipment work, so a like-for-like HVAC change-out still needs its own permit. The minimum permit fee is $85, and the permit cost is based on the value of the installation. A homeowner may pull the mechanical permit only for a home they own, occupy, and are not selling or leasing, and must sign the affidavit of ownership. Guilford County's own permitting office is the Guilford County Inspections Department, reachable on 336-641-3707 at https://www.guilfordcountync.gov/government/departments-and-agencies/inspections. Its online permit portal is https://citizenaccess.guilfordcountync.gov/energov_prod/selfservice#/home. 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.
