Air Conditioning in Charleston: what's different
Air Conditioning work in Charleston follows the local climate. In hot-humid climates the air conditioner removes moisture as well as heat, so refrigerant charge, airflow and a clear condensate drain matter as much as raw capacity. Oversized systems short-cycle and leave rooms clammy.
A common Charleston pattern: 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.
The air conditioning services Charleston homeowners ask for most are coil Cleaning. Dust, cottonwood fluff and grease cleaned from condenser and evaporator coils.
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.
