If you live within a few miles of Mobile Bay or the Gulf, your condenser is working against something inland homeowners never deal with: salt. Corrosion on coil fins and electrical contacts shortens equipment life dramatically, and the damage tends to show up long before the system actually fails.
What salt does
Airborne salt settles on the aluminum fins and the copper tubing of the outdoor coil. Over time it pits the fins, opens tiny leaks at the tube-to-fin joints, and corrodes contactor points and wire terminals. A unit that would run 15 years inland can be finished in eight or nine within sight of the water.
What actually helps
- Rinse the coil. Fresh water from a garden hose every couple of months, power off, is the single highest-value thing you can do.
- Coil coatings. On a new install near the water, a factory-applied coating is worth the money.
- Keep clearance. Two feet around the unit, and do not let irrigation spray hit it.
Catch it early
Early fin pitting is visible if you know what to look for. We check for it on every coastal maintenance visit and treat the coil before it costs a compressor. Call 251-463-8031 to book a visit.
