In North Carolina, a HVAC Installation requires a mechanical permit.
Installing or replacing HVAC equipment requires a mechanical permit and inspection; even a same-size, same-location swap generally needs one. Routine maintenance and minor repairs are exempt, and a gas-to-heat-pump conversion also requires an electrical permit. Plans are reviewed under the Statewide code (IRC 2015); apply through Lenoir County Planning & Inspection Department before work begins.
