Protect Your HVAC System from Corrosion: Expert Tips from AAA Furnace
If you’re a homeowner in San Jose or the Silicon Valley area, ensuring your HVAC system’s longevity and efficiency is crucial. One common threat that can silently damage your system is coil corrosion. At AAA Furnace & Air Conditioning, we recognize the importance of maintaining your HVAC components to avoid costly repairs and breakdowns.
Understanding HVAC Coil Corrosion
HVAC coil corrosion can pose a significant risk to your system’s performance. The evaporator coil, located in the indoor air handler, and the condenser coil, situated outdoors, are essential for the cooling process. Copper tubing within these coils is particularly reactive to certain elements, making them susceptible to corrosion over time.
In indoor environments, airborne chemicals from detergents, cleaners, and construction materials can combine with condensate on coil surfaces, leading to gradual deterioration and pinhole leaks. Outdoor units are exposed to natural elements such as salt from ocean air and man-made pollutants like fluoride and chlorine, which can accelerate copper corrosion.
Preventive Measures to Safeguard Your HVAC System
At AAA Furnace, we recommend proactive steps to prevent HVAC coil corrosion and maintain system efficiency:
Regular Inspections: Schedule annual preventive maintenance with our qualified HVAC technicians to inspect the evaporator coil for corrosion. We use pH-balanced coil cleaners to neutralize acids and restore energy efficiency.
DIY Maintenance: For outdoor units, you can perform basic maintenance by flushing internal coil surfaces with water from a garden hose. This simple step helps remove damaging residues and prevents corrosion.
Professional Assistance: Contact AAA Furnace for comprehensive coil corrosion prevention services tailored to your HVAC system’s needs. Our expert team will ensure your coils remain corrosion-free, allowing your system to operate at peak performance.
