General

Salt air ruins outdoor HVAC units in Murrells Inlet. Metal pits. Coils corrode. Screws and panels rust out. The system loses efficiency and starts to fail. Ignore the buildup, and you’ll be paying for repairs or a full replacement long before you expect it.

Real Protection That Works

Coastal HVAC units need more than a rinse. They need armor. Here’s what holds up on the coast:

Marine-grade coatings: thick, tough, and built to block salt
Sacrificial anodes: these take the hit so your core parts don’t
UV-resistant sealants: keep sun and salt from eating metal
Anti-corrosive sprays: form a shield on every exposed surface
Powder coating: locks out moisture and salt for the long haul

Skip these, and you’re gambling with your investment. HVAC installation on the coast demands this level of protection. Once corrosion starts, it doesn’t stop. The only way to win is to keep salt out from day one.

Maintenance That Actually Matters

Salt doesn’t care about your schedule. It builds up every day. A quick rinse with fresh water knocks it down before it can dig in. But that’s just the start. Our professional maintenance service goes after the hidden spots: inside coils, under panels, around every screw and wire. We spot the first signs of trouble before they turn into breakdowns.

Covers help, but only if they breathe. A sealed cover traps moisture. That’s just as bad as salt. The right cover blocks spray but lets air move. No mildew. No trapped salt. Just a clean, protected unit waiting for the next run.

What a Real Coastal Maintenance Plan Looks Like

Coastal HVAC care isn’t a once-a-year job. It’s a routine. Here’s what keeps systems alive in salt country:

Weekly: walk around the unit. Look for white crust, rust, or green spots. Catch them early.
Monthly: hose down the outdoor unit with fresh water. Don’t blast it, just rinse off the salt.
Quarterly: bring in a pro for a deep clean. We pull panels, check coils, and hunt for hidden corrosion.
Twice a year: inspect every coating. Touch up bare spots. Replace anodes if they’re eaten away.
Yearly: run a full system evaluation. Test performance. Check refrigerant. Make sure nothing’s slipping through the cracks.

Skip a step, and you’ll see the results. Salt finds the weak spots. Regular attention from our indoor air quality specialists keeps the system running strong, even when the air feels thick with salt.

Spot the Damage Before It Wins

Salt leaves clues. White powder on metal. Rust streaks under screws. Fins that look fuzzy or green. The outdoor fan starts to whine. Cooling drops off, even when the thermostat is set low. These aren’t small annoyances: they’re the start of real damage. When you see them, it’s time for professional HVAC service. Wait, and you’ll be swapping out parts or losing the whole system.

Why Coastal Units Fail Early

Most HVAC units away from the coast last a decade or more. On the coast, five years can be a stretch without the right care. Salt eats wires. Insulation goes brittle. Circuit boards short out. Even the best brands can’t fight salt alone. The difference comes down to protection and maintenance. Units with regular care keep running. Neglected ones grind to a halt, sometimes in the middle of a heatwave.

Compressor failure: salt shorts the windings
Fan motor burnout: corrosion locks the bearings
Refrigerant leaks: pitted coils let gas escape
Thermostat errors: corroded wires send bad signals

Every failure costs more than a simple rinse or coating. The right plan saves money, time, and frustration.

What Sets Coastal HVAC Pros Apart

Not every technician understands salt. Coastal pros know where to look. We see the hidden rust under the fan blade. We spot the green fuzz on a relay. We know which coatings last and which ones flake off after a season. Our team uses tools and products built for the coast. We don’t guess. We fix what matters and protect what lasts.

When you call in a coastal HVAC specialist, you get more than a cleaning. You get a system that stands up to the worst the ocean can throw at it. That’s the difference between a unit that limps along and one that cools strong, year after year.
