Questions regarding applicable building code requirements, inspection or enforcement should be referred first to the local building inspector and then to the South Carolina Department of Labor, Licensing, and Regulation. Residential buildings comply with the Energy Code if they meet certain criteria.

SC Duct and Envelope Tightness Verifier

South Carolina has adopted the 2009 International Energy Conservation Code (IECC), which requires leak testing of duct systems if the duct is outside the conditioned area of the home. The South Carolina Duct and Envelope Tightness (SCDET) Verifier training instructs HVAC technicians and installers on how to perform this required duct leak testing, as well as building envelope leak testing. All participants who successfully complete the training will be listed in the SC Association of Heating & Air Conditioning Contractor's SCDET database.
