Do I need a permit for hvac replacement or installation in Mauldin?
Yes. In South Carolina, hvac replacement or installation generally requires a permit, and Mauldin 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. Mauldin explicitly requires a permit before adding or replacing any water heater, space heater, or air conditioning equipment, so an HVAC change-out is permitted work, not an exempt repair. All work must conform to the International Codes as adopted by the State of South Carolina and the City of Mauldin, and the trade work generally must be done by a South Carolina LLR licensed contractor.
