Living near the ocean can be a dream come true for many homeowners. The soothing sound of waves, breathtaking views, and fresh sea breeze create a unique ambiance. However, along with these perks, coastal living also comes with its own set of challenges, particularly when it comes to maintaining your home’s HVAC system.

Homes close to salt water are more exposed to damaging results on their units. The salt in the air can lead to rust and corrosion, which can have serious consequences for your HVAC system. Here are some examples of the potential issues:

Rust and Corrosion:
Salt water can accelerate the rusting process of metal components in your HVAC system. Over time, this can weaken the structural integrity of the unit and compromise its functionality.

Refrigerant Leaks:
Rust and corrosion can eventually cause refrigerant leaks. When refrigerant levels drop, the system may struggle to maintain the desired temperature, leading to increased energy consumption and higher utility bills.

Freezing Up:
Refrigerant leaks can cause the system to freeze up, rendering it inoperable. This not only disrupts your comfort but also requires costly repairs to fix.

Shorter Lifespan:
The cumulative effect of saltwater damage can significantly shorten the lifespan of your HVAC system, leading to premature replacement and added expenses.

To mitigate the effects of salt water damage on your HVAC system, here are some recommendations:

1. Regular Maintenance:
Schedule routine maintenance checks with a qualified technician from Fix-It 24/7. Regular inspections allow professionals to identify and address potential issues before they escalate, keeping your HVAC system in optimal condition.

2. Coil Cleaning:
Clean the coils of your HVAC unit regularly to remove salt buildup. Use a gentle detergent and water solution to dissolve the salt deposits, ensuring proper airflow and system efficiency.

3. Filter Replacement:
Replace air filters frequently, ideally every one to three months. Salt particles can quickly accumulate on filters, obstructing airflow and reducing indoor air quality. Clean filters ensure efficient operation and prevent strain on the system.

4. Protective Coatings:
Consider applying protective coatings to the exterior components of your HVAC system to shield them from saltwater exposure. Anti-corrosion coatings can help prolong the lifespan of your unit and mitigate the effects of coastal environments.

5. Elevated Installation:
If possible, install your outdoor HVAC unit on an elevated platform to minimize its exposure to saltwater spray and flooding during storms or high tides. Positioning the unit strategically can reduce the risk of corrosion and damage.

6. Dehumidification:
Invest in a dehumidification system to regulate indoor humidity levels. Lower humidity not only enhances comfort but also helps prevent moisture-related issues and corrosion within your HVAC system.

7. Professional Inspections After Storms:
Following severe weather events, such as hurricanes or tropical storms, schedule a professional inspection of your HVAC system. Saltwater intrusion and debris can cause significant damage, necessitating prompt repairs or replacements.
