Do I need a permit for hvac replacement or installation in Town of Mooresville?
Yes. In North Carolina, hvac replacement or installation generally requires a permit, and Town of Mooresville 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. HVAC work is an express exception to the North Carolina $40,000 permit exemption under NCGS 160D-1110(c), so a change-out needs a mechanical permit regardless of cost. Under NCGS 160D-1110(d) a separate permit is generally required for each appliance installed, and gas fired equipment normally adds a second permit and a pressure test. Iredell County's own permitting office is the Iredell County Development Services Department, reachable on 704-878-3113 at https://www.iredellcountync.gov/232/Development-Services. Its online permit portal is https://selfservice.iredellcountync.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.
