Local homes
Charleston housing and HVAC
Historic homes are often raised with ducts in crawl spaces or attics, and many use multiple small systems or ductless units. Newer homes are built on raised foundations or slabs with heat pumps.
Charleston has hot, very humid summers and mild winters. Tidal flooding, heavy rain and hurricanes are major risks, and salt air affects outdoor equipment.
Permits and seasonal timing in Charleston
The City of Charleston Building Inspections Division issues mechanical permits, and the Board of Architectural Review may need to approve visible equipment in historic districts. South Carolina licenses mechanical contractors through the Contractor's Licensing Board.
Historic district rules
Outdoor units and line sets visible from the street may need approval and careful screening.
Flooding
Tidal and storm flooding can damage ground-level equipment and crawl space ducts.
Humidity and mold
High humidity makes dehumidification and duct sealing important, especially in raised historic homes where crawl space air can be pulled into the system.
