How to Prevent HVAC Coil Corrosion

What Is HVAC Coil Corrosion?

Coil corrosion occurs when the coils in your heating, ventilation, and air conditioning system deteriorate due to exposure to various corrosive elements. This issue can affect both outdoor units and indoor evaporator coils, leading to reduced efficiency and higher energy costs.

The primary cause of outdoor coil corrosion is environmental factors, including humidity and airborne pollutants. Indoor coils can also suffer from corrosion, mainly due to airborne volatile organic compounds (VOCs) emitted by household materials. These compounds can react and form corrosive acids on the coils, leading to deterioration over time.

Signs of Coil Corrosion

Early detection of HVAC coil corrosion can help you avoid expensive repairs. Here are some common signs that may indicate your coils are corroded:

Reduced Cooling Efficiency: If your HVAC system is struggling to maintain comfortable temperatures, it could be a sign of corroded coils.
Higher Energy Bills: An unexpected increase in energy costs may signal that your system is working harder to compensate for leaking refrigerant due to corrosion.
Airflow Issues: Difficulty in getting sufficient cool air can point to corrosion affecting coil performance.
Visible Damage: Inspect your coils for any signs of rust or holes, which can indicate significant corrosion.

How to Prevent Coil Corrosion

Taking preventive measures can help you avoid the costly consequences of coil corrosion. Here’s how you can protect your HVAC system:

Routine Maintenance: Schedule regular maintenance with your HVAC technician, who can clean the coils using solutions that neutralize corrosive buildup.
Install Whole-House Air Cleaners: Adding an air cleaner to your HVAC system can help eliminate VOCs, improving your indoor air quality while protecting your coils.
Monthly Cleaning: Rinse your outdoor condenser coil with plain water monthly to wash away debris and contaminants that can lead to corrosion.
Apply Anti-Corrosive Coatings: Consult your HVAC professional about applying protective coatings to the coils and fins to extend their lifespan.
