What's different about HVAC services in Charleston

Charleston’s HVAC needs follow a climate with average January temperatures of 50.8°F, July temperatures of 82.3°F, and 44.26 inches of annual precipitation at downtown Charleston. That makes regular HVAC upkeep part of planning for drainage and exterior sealing as well as indoor comfort. In Harleston Village, Radcliffeborough, and Cannonborough/Elliottborough, ask whether the existing system, ductwork, electrical work, or exterior equipment needs work beyond the immediate diagnosis. For diagnosis, electrical, gas, or refrigerant work, use a certified HVAC technician.

HVAC equipment installation or replacement may require a local permit; confirm requirements with the City of Charleston Permit Center (Building Inspections Division) before work begins.
