Coastal Heating and Air
Coastal heating and air systems are specialized HVAC units engineered to withstand the corrosive effects of salty, humid environments found near oceanfronts. Unlike standard units, a dedicated coastal HVAC unit utilizes advanced materials—such as welded aluminum coils and reinforced coatings—to prevent premature failure caused by salt spray and galvanic corrosion.
Living on the coast offers breathtaking views, but the harsh seacoast air can wreak havoc on standard outdoor equipment. To combat this, Carrier has engineered an innovative line of outdoor products featuring exclusive, patented welded aluminum coil technology. These advanced coastal heating and cooling solutions deliver the reliable comfort and performance you expect, backed by exceptional corrosion resistance for lasting durability.
Why Corrosion Resistance Matters For Coastal HVAC
Salty air is relentless. If your home is within two miles of a coastline, your HVAC system is constantly exposed to corrosive elements that can degrade performance and shorten equipment lifespan.
The severity of this corrosion depends on several factors:
- Proximity: Distance from the ocean.
- Environment: Wind direction, relative humidity, and coil temperatures.
- Contaminants: Pollution, road salt, and even local irrigation systems.
Without specialized protection, standard copper-aluminum coils can suffer from galvanic corrosion, leading to refrigerant leaks and system failure. Investing in a purpose-built coastal HVAC unit is the most effective way to ensure long-term comfort and efficiency.
Carrier’s Answer To Corrosion – Coastal Air Units With Welded Aluminum Technology
Innovation is at the heart of Carrier’s solution. Prior to 2023, many coastal heating and air models relied on copper tubes with aluminum fins. To eliminate the risk of galvanic corrosion between dissimilar metals, Carrier transitioned all coastal models to our patented welded aluminum coil technology.
This shift represents a major leap forward in durability. Key benefits of welded aluminum include:
- Enhanced Durability: A zinc cladding layer applied for superior corrosion resistance.
- Robust Construction: Tubing walls are 71% thicker than standard copper tubing.
- Extended Lifespan: Up to 81% better projected lifespan compared to copper coils.
- Sealed Protection: Special heat shrink wrap is applied to all factory-brazed copper-aluminum joints to isolate them from seacoast air.
- Proven Reliability: Extensive salt spray testing shows no degradation of fins after seven years (and counting).
Additional Protection For Coastal HVAC Units
Our commitment to quality goes beyond the coil. Carrier has implemented comprehensive upgrades across our coastal product line to defend against the corrosive nature of seacoast air. These enhancements ensure your coastal heating and cooling system remains aesthetically pleasing and operationally sound:
- Thicker fan guard with polyester powder coat.
- Thicker zinc plating on hardware.
- A robust two-layer coating process (replacing the standard single layer).
- Increased overall coating thickness for maximum shielding.
