134 AC Repair Contractors in Charleston, SC

Charleston’s coastal Lowcountry climate drives steady demand for cooling work: long, hot summers with 89°F highs, persistent 78% humidity and Atlantic moisture push latent loads from May through September, and salt air accelerates corrosion on outdoor equipment. That climate profile explains why 37 contractors serve the area, averaging a 4.6 rating across 20,509 reviews and why 13 firms advertise 24/7 service for urgent ac-repair Charleston calls.

Prices vary by the scope of work and the most common high-cost items are condenser and compressor replacements, refrigerant recharge, and coil or corrosion repairs; labor and coastal corrosion protection also add to invoices. South Carolina requires HVAC contractors to hold the Mechanical Contractor (Group 2 — HVAC) license from the Contractor’s Licensing Board, so ask for that credential and written, itemized estimates that separate parts, labor, and any corrosion mitigation measures.

Customer highlights weren’t provided, but market signals are clear: a relatively high average rating and multiple 24/7 providers reflect heavy seasonal demand. When selecting a technician, prioritize documented diagnostics, corrosion-aware maintenance plans, clear warranty terms, and experience with moisture control and refrigerant management. Request references for beachfront or marsh-adjacent installs and confirm emergency response times before hiring.
