Coastal Salt Corrosion / Air Conditioning

Air conditioning along the hot and humid coastlines have definitely become a must. Unfortunately, by necessary design, these systems often pre-maturely fail within  this environment due to coastal salt corrosion. The necessary metal combinations used to make up the air conditioning unit is not suitable for this type environment.

High humidity and salt contents wreak havoc to the outside condensing unit. Turning it to rubble within a short period while causing it to consume greater amounts of energy in the mean time.

Copper and aluminum are the primary metals used within the system. Copper is used because of its ability to withstand the high pressure generated from the refrigerants transformations (gas state to a liquid state).

while aluminum is used because of its excellent thermal transfer rate. The combination of these two metals in a salt air environment create the perfect environment for rapid degradation from galvanic corrosion.

The air conditioning unit is designed to condition air. Contrary to popular belief, it does not manufacture cold air. It merely transfers heat from the living space to the outdoors and replaces it with conditioned air.


The ability of the unit to efficiently perform this transformation relies heavily on the heat transfer that takes place via the outside condenser coil.

Although, your coastal home or condo’s hardest working component is probably located in an out of sight, out of mind location, it’s imperative that you maintain the integrity in order to maintain its efficiency and achieve years of service from it.


We’d love to hear from you.

Do you live along the coast and have had to suffer from pre-mature equipment failure/excessive energy usage due to coastal salt corrosion? Let us know your story.
