AC Replacement in North Charleston, SC: What to Expect
North Charleston's coastal South Carolina Lowcountry climate creates relentless summer heat, with temperatures climbing to 89 F while humidity hovers near 78%, pushing the heat index well past the thermometer from May through September.

Homeowners in this Charleston metro suburb rely on a competitive market of 26 contractors, who collectively maintain a 4.4 average rating across more than 5,200 client reviews.
For homeowners weighing a system upgrade, the investment varies by capacity and efficiency. A basic 3-ton central AC runs $5,500 to $11,000, while a mid-efficiency 4-ton unit spans $7,500 to $14,000.
