Don’t Come Back to Mold

Best AC Settings for Gulf Shores Condos When You’re Away

If you own a condo in Gulf Shores, you probably know the feeling:

You open the door after being gone for a few weeks…
and get hit with that smell — musty, damp, maybe even a little moldy.

Most of the time, this doesn’t happen because the condo is “old.”
It happens because the air conditioner was set wrong while you were gone.

Let’s fix that.

Why Gulf Shores Condos Are So Prone to Mold

Gulf Shores is hot, humid, and salty almost year-round. That’s tough on a building, and even tougher on a closed-up condo:

  • Humidity stays high, even when it isn’t blazing hot.
  • Condos are stacked together, so there’s less air movement.
  • Many owners close everything up tight and leave for weeks or months.
  • The AC may be turned too high or completely off to “save money.”

When the air in your condo sits warm and wet, you create a perfect environment for:

  • Mold on walls, ceilings, and vents
  • Musty odors in furniture and closets
  • Swollen doors, trim, and cabinets

A couple of weeks like that is all it takes.

The Big Question: Should You Turn the AC Off?

For Gulf Coast condos, the short answer is:

No — don’t turn your AC completely off when you leave.

On paper, it looks like you’re saving money.
In reality, you’re gambling with:

  • Mold remediation costs
  • Repainting and replacing trim
  • Angry guests (if you rent it out)
  • Your own health if you’re sensitive to mold

Running the AC enough to control temperature and humidity almost always costs less than cleaning up the mess later.

Best AC Settings for Your Gulf Shores Condo When You’re Away

Here’s a simple starting point you can use (and that we can fine-tune for your specific condo):

  • Mode: COOL
  • Fan: AUTO
  • Temperature: 77–78°F while you’re gone
  • If you have humidity control: aim for 50–55% indoor humidity

Why these settings work

  • Not too cold: You’re not paying to keep the condo at 72°F while it’s empty.
  • Not too hot: 77–78°F is warm enough to save money, but cool enough to let the system pull moisture out of the air.
  • Fan on AUTO: This lets the system cycle normally and drain condensation, instead of constantly blowing moist air around.

If your thermostat has a “dry” or “dehumidify” mode, or lets you set a humidity target, that’s even better. We can help you set that up.

Before You Leave: Quick Condo Checklist

Use this simple checklist any time you’re about to head home for more than a few days:

  • ✅ Set the thermostat to COOL, 77–78°F (and humidity control if you have it)
  • ✅ Open interior doors so air can move through bedrooms, closets, and bathrooms
  • ✅ Make sure supply and return vents are not blocked by furniture or rugs
  • ✅ Throw away trash and remove any wet towels or bathmats
  • ✅ Close windows and sliding doors tightly to keep humid outside air out
  • ✅ Check the filter – replace if dirty so the system can dehumidify properly

Optional: run ceiling fans on low if you like, but remember: fans move air, they don’t remove moisture. The AC and/or dehumidifier does that job.

Special Advice for Airbnb / VRBO & Snowbird Owners

If your Gulf Shores condo is a rental, humidity control isn’t just about comfort — it’s about reviews and repeat bookings.

A few tips:

  • Post a small sign by the thermostat with “Do Not Turn Off – Recommended Settings.”
  • Ask your cleaner to check the thermostat after every checkout.
  • Use a smart thermostat so you can:
    • Check temperature and humidity from your phone
    • Bump temps up or down between guests
    • Get alerts if the system stops working while you’re out of town

Snowbirds can do the same thing between long visits. You don’t have to wonder what’s going on — you can see it.

When You Might Need More Than Just the AC

Sometimes, the AC is doing all it can, and the condo still feels sticky or smells musty when you arrive. That’s a sign you may need:

  • A whole-home dehumidifier tied into your ductwork
  • Ductwork inspection for leaks pulling in humid attic or hallway air
  • Coastal-rated equipment if your current system is older and heavily rusted from salt air
  • A professional check for existing mold issues

If you’re fighting the same musty smell every time you arrive, it’s worth having us look things over.
