HVAC systems can face unique challenges, particularly in coastal regions such as Florida, making choosing the best system crucial for long-term performance. Salt, sand, humidity, and coastal storms can all negatively affect systems that are not built for that environment, leading to extended issues, frequent repairs, and even replacements. Homeowners near the coast should choose HVAC systems engineered and built for durability, corrosion resistance, and performance stability, even in the harsh coastal environment. We are going to help you determine the best HVAC systems for coastal living, as we at All Year Cooling and Plumbing have been working with homeowners in Florida’s unique and challenging climate for decades.
Unique Coastal HVAC Challenges
HVAC systems face many challenges in coastal environments, and it’s essential to understand what they are and how they affect these systems.
Salt and Air Corrosion
Coastal environments have much more salt and wind than other environments due to the ocean being so close. Salt in the air can accelerate rust on metal components of the system, such as coils, fins, and outdoor units. Ultimately, this rust will impact the lifespan and efficiency of the system, resulting in repairs or, in extreme cases, the replacement of the system itself.
High Humidity
Although humidity in everyday contexts is manageable by HVAC systems, in coastal environments, it is typically much higher, which can cause problems. Cooling systems will experience increased strain due to humidity, and there is an increased risk of mold and mildew without proper dehumidification.
Sand and Dirt
Coastal areas are typically much sandier and windier, which can cause sand to enter the HVAC system. Sand is an abrasive particle that can damage the system’s blades, coils, and filters, leading to frequent maintenance or replacement.
Coastal Storm Exposure
Coastal storms can be more damaging than a typical storm in non-coastal areas due to higher humidity, sand, and the risk of flooding. It’s crucial to ensure your HVAC system is installed correctly and anchored in coastal environments. It’s also recommended to cover your HVAC system in the event of heavy rainfall and to lift it off the ground to prevent flooding.
Features for Coastal HVAC Systems
When installing an HVAC system or assessing your current system, it’s essential to understand which features are necessary to ensure it is fit for coastal environments. Here is a list of features that should be a part of your coastal HVAC system to ensure it is suitable for the unique environment.
Corrosion-Resistant Materials: Due to the increased water and sand in coastal climates, it’s essential to use corrosion-resistant materials such as epoxy-coated coils, stainless steel, and anti-corrosion paint finishes.
Sealed Components: Weather-sealed electrical components, sand-resistant fans, and advanced filters are all essential in coastal environment HVAC systems.
Enhanced Dehumidification Abilities: Increased humidity can cause immense problems for HVAC systems in coastal environments, which calls for built-in humidity control features and even full-home dehumidifiers.
Storm Resistance: The HVAC system should be fully storm-resistant, with units rated for high-wind zones. They should also be tied down with hurricane tie-down kits and elevated in flood-prone areas.
Best HVAC System Types for Coastal Environments
At All Year Cooling and Plumbing, we have been serving the Florida area for decades, and our team is experienced with the Sunshine State’s unique, harsh climate. With that said, here are our top recommendations for the best types of HVAC systems for coastal climates, based on all the necessary features and unique challenges we’ve discussed above.
Ductless Mini-Split Systems
Ductless systems are great for smaller homes or for adding heating and cooling to other homes. The indoor and outdoor separation helps reduce exposure to salt and sand, preventing frequent maintenance issues and corrosion of system components.
Coastal-Rated Central Air Conditioners
This specific type of HVAC system is designed entirely with anti-corrosion materials and coatings to prevent rusting or other issues with the internal parts. It’s ideal for typical single-family homes in coastal environments such as Florida.
Packaged HVAC Units
These HVAC units are built with a self-contained design that reduces exposure to external elements, protecting the system itself. Oftentimes, they are built with storm-resistant casings, which are crucial in coastal environments that experience frequent storms, strong winds, and potential sand corrosion.
Geothermal Systems
These systems are installed underground to help protect them from salty air and storms that can cause immense damage. It’s an ideal option for homeowners seeking long-term efficiency and durability.
Best Practices for the Extended Lifespan of Coastal HVAC Systems
Having a unit built for coastal climates is crucial to ensuring a longer lifespan; however, we have a list of best practices you can follow as a homeowner to give your system the best chance of lasting without repetitive repairs or maintenance needs.
- Clean your coils regularly to ensure that salt buildup and corrosion are addressed
- Change your filters quarterly to avoid sand and dust clogging
- Get annual professional inspections done by All Year Cooling and Plumbing
- Install storm straps and surge protectors for hurricane-prone regions
- Rinse outdoor units with fresh water to reduce salt buildup
