AC Repair Service in Charleston, SC

For historic Charleston homes without existing ductwork, ductless mini-split systems are the best solution. Mini-splits require only a 3-inch hole in the wall for installation, preserving your home's architectural integrity while providing efficient heating and cooling. They offer zone-by-zone temperature control, are whisper-quiet, and meet historic preservation guidelines. Maximum Air Experts has installed hundreds of ductless systems in Charleston's historic district, South of Broad, and Harleston Village homes. We're experienced with BAR requirements and work to maintain your home's character while delivering modern comfort.

HVAC repair costs in Charleston typically range from $150 to $500 for common repairs like capacitor replacement, refrigerant recharge, or thermostat issues. More complex repairs such as compressor replacement or major component failures can range from $800 to $2,500. Maximum Air Experts provides upfront pricing before any work begins — you'll know the exact cost before we start. We never charge hidden fees, and our service call fee is applied toward the repair cost if you proceed with the work. Emergency and after-hours service is available at competitive rates.

Several factors can cause an AC to run without cooling in Charleston's humid climate: dirty air filters restricting airflow, frozen evaporator coils from low refrigerant, a faulty compressor, clogged drain lines, or outdoor unit issues from salt air corrosion. Charleston's high humidity can also overwhelm undersized systems. If your AC is running but not cooling, turn it off and check your filter first. If that's clean, call Maximum Air Experts at +1-843-599-3506 for same-day diagnosis. Our technicians carry common parts and can often complete repairs in a single visit.
