62 AC Replacement Contractors in Charleston, SC

Charleston’s coastal Lowcountry climate pushes air conditioners harder than most regions: long stretches of 89°F highs, 78% humidity and constant Atlantic moisture mean systems must remove latent heat as much as sensible heat. That environment drives steady demand for ac-replacement Charleston, and the local market reflects it — 17 contractors serving the area average a 4.6 rating across 6,427 reviews, with eight offering 24/7 service.

Specific price points from top cost items were not provided, but homeowners should expect variability driven by unit capacity, SEER rating, corrosion-resistant components for salt air, ductwork condition, and installation complexity. Permits and home access can add labor. South Carolina requires a Mechanical Contractor (Group 2 — HVAC) license from the Contractor’s Licensing Board, so confirm any bid is from a properly licensed company before work begins.

No individual customer highlights were supplied, so look instead for consistent review themes: responsiveness during summer peaks, experience with coastal corrosion mitigation, and proactive maintenance plans. Prioritize contractors who document warranties, provide written estimates with system sizing, and explain moisture-control strategies and long-term service options rather than just quoting equipment prices.
