Coastal Heating and Air

By Travis Baugh

If you live near the coast, you know the effects that harsh seacoast air can have on an HVAC unit. Carrier offers a new line of outdoor products with exclusive, patented welded aluminum coil technology. These new outdoor products will help deliver the comfort and performance you expect with exceptional corrosion resistance for lasting durability.

Why Corrosion Resistance Matters For Coastal HVAC

Living in a coastal area brings with it the unique challenge of corrosive seacoast air. Salt water can be carried as far away as two miles from the coast. The severity of corrosion depends on distance from ocean, wind direction, relative humidity, and coil temperatures. Corrosion can also be caused by pollution, road salt and irrigation systems.

Carrier’s Answer To Corrosion – Coastal Air Units With Welded Aluminum Technology

Prior to 2023, Carrier coastal air conditioner and heat pump models used a copper tube and aluminum fins. To avoid galvanic corrosion between these two metals, Carrier transitioned all coastal models to its patented welded aluminum coil technology. Welded aluminum benefits include:

  • Zinc cladding layer applied for improved corrosion resistance.
  • 71% thicker wall than our current copper tubing.
  • Up to 81% better projected lifespan vs. copper coil.
  • Special heat shrink wrap applied to all factory-brazed copper-aluminum joints to isolate from seacoast air.
  • Extensive salt spray testing during development – showing no degradation of fins after seven years (and counting).

Additional Protection For Coastal HVAC Units

In addition to improving the coil, Carrier has also made other improvements throughout our coastal products to protect from the corrosiveness of the seacoast air including a thicker fan guard polyester powder coat, thicker zinc plating, a two-layer coating process instead of one, and an increase in overall coating thickness.
