About This Market

Salt air wreaks havoc on equipment, shortening lifespans and driving replacement cycles. Competition is fierce with 1701 licensed establishments statewide, many clustering around Charleston metro. Heat pumps rule here - dual fuel systems for occasional freezes, but cooling capacity is king. Coastal building codes add complexity and cost.

Learn Mount Pleasant's permit system inside out - they're stricter than Charleston proper. Build relationships with local inspectors and schedule early, especially during peak season. Stock parts for salt air corrosion issues - condenser coils, electrical components, and ductwork take a beating. Price jobs knowing you'll be back sooner than inland markets. Emergency service pays premium rates here, but response time expectations are brutal in summer.
