Salt-Air Coil Corrosion
Our coastal air is packed with salt, which eats raw aluminum and copper coils for breakfast. In spring and summer, this salt combines with high humidity to accelerate galvanic corrosion. Homeowners from Landfall down to Carolina Beach need to rinse their outdoor condenser coils with low-pressure fresh water monthly. Do not use a pressure washer; you will bend the delicate aluminum fins. A simple, gentle garden hose rinse removes the crusty salt buildup, keeping heat transfer efficient and preventing premature coil leaks that lead to expensive refrigerant recharges.
