Thermostat repair in Johns Island: Problems We Fix

Coastal humidity and salt air are hard on air conditioners in Johns Island. Condenser coils corrode faster, drain lines clog with algae, and systems run long hours pulling moisture out of the house.

“Our AC died on a Saturday in July and they were here in under two hours. Quoted a flat price, fixed the capacitor and fan motor, and the house was cold again before dinner.”

Marcus T., Johns Island
