Coastal Salt Air AC Protection Guide for Long Island
How airborne ocean salt accelerates aluminum fin corrosion and how to protect coastal HVAC condensing units.
Airborne ocean and bay salt on Long Island can degrade standard aluminum condenser coils in as little as 3 to 5 years, leading to refrigerant leaks and loss of heat transfer efficiency.
Properties within 2 to 3 miles of the Long Island Sound, Atlantic Ocean, or Great South Bay should specify factory-applied epoxy coatings or marine-grade phenolic coil protection.
Routine spring maintenance for coastal units must include low-pressure freshwater rinsing of condenser coils and dielectric paste on outdoor electrical connections.
