Do I need a permit for hvac replacement or installation in Columbia?
Yes. In South Carolina, hvac replacement or installation generally requires a permit, and Columbia 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. The City of Columbia publishes a Mechanical Permit application and describes mechanical work as a Building Trade Permit, so a heating or cooling system change-out is a permitted activity rather than an exempt repair. Trade permits in Columbia are typically pulled by a licensed contractor, or by an owner-occupant using a Homeowner Affidavit.
