Living by the coast has many benefits: beautiful scenery, cool breezes, and the soothing sound of crashing waves. However, coastal living also comes with its own unique challenges, particularly when it comes to maintaining your Heating, Ventilation, and Air Conditioning (HVAC) system. The air quality along the coastline is different from other regions due to higher levels of salt and moisture content. This can affect the performance and lifespan of your HVAC unit.
Salty sea air causes significant wear and tear on an HVAC system. The primary reason is that saltwater in the air can lead to corrosion, which is a chemical reaction between a metal surface (in this case, components of your HVAC system) and its environment that leads to gradual degradation.
Saltwater corrosion accelerates rusting in metal parts. When these salty coastal breezes make their way into your HVAC unit, they can cause this rusting process to quicken dramatically. Over time, this corrosion affects both the exterior and interior parts of your HVAC unit — damaging coils, fins, compressors and other key components — leading to decreased efficiency or even total failure.
