The same air conditioner lives a different life two miles from the Jupiter Inlet than it does twenty miles inland. Salt rides the sea breeze, settles on coils and cabinets, and goes to work on every piece of metal it finds. An installation that ignores that starts aging the day the crew leaves.
What salt actually does
Condenser coils corrode from the fin edges in, quietly taxing capacity. Cabinet fasteners rust and streak. The small electrical parts go first: contactor points pit, spade terminals corrode, capacitor cans rust at the crimp. None of it is dramatic until an August afternoon when the margins run out.
Spec for the coast
Within the salt line, the equipment conversation should include coastal-rated or coated coil options, cabinet placement out of the direct spray path, and hardware choices down to the screws. It is not upsell theater; it is the difference between a system that looks ten years old at four and one that simply keeps working. A freshwater coil rinse at every maintenance visit does the rest.
And the part that has nothing to do with salt
Sizing. Oversized systems short-cycle, control humidity badly and die young, and coastal homes with sealed impact glass are routinely oversized by rule-of-thumb quoting. The load calculation on the actual house, windows, orientation, insulation and ducts included, is what the equipment choice should stand on. Anyone quoting tonnage over the phone is guessing with your money.
Add Palm Beach County permitting and current wind-code anchoring, handled inside the quote rather than discovered later, and you have the whole picture of what a coastal install involves.
