Do I need a permit for hvac replacement or installation in Myrtle Beach?
Yes. In South Carolina, hvac replacement or installation generally requires a permit, and Myrtle Beach is no exception.
A like-for-like air conditioner or furnace change-out still requires a mechanical permit in South Carolina jurisdictions, even though it feels like a simple swap. Sizing should follow a proper load calculation. An oversized unit can be flagged and creates comfort and humidity problems. Myrtle Beach permits are handled by the City of Myrtle Beach Construction Services and Buildings, reachable on 843-918-1111 at https://www.cityofmyrtlebeach.com/departments/construction_services/index.php. Horry County runs its own building permit office as well, so confirm whether Myrtle Beach or the county handles your address before you apply. A change-out is normally a mechanical permit, and gas fired equipment usually adds a second permit and a pressure test.
