Duct sealing in Mount Pleasant: Problems We Fix

Coastal humidity and salt air are hard on air conditioners in Mount Pleasant. 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.”
