Florida summers are no joke—especially when it comes to heat and humidity. Floridians are used to our glasses steaming up every time we go outside this time of year but inside we want it cool and dry. 

One of the top questions I get this time of year from new homeowners in Ponte Vedra Beach and Jacksonville area is:
“How do I keep my home from getting musty—or worse, moldy?”

I’m not a mold expert. But as a Florida resident (and a real estate agent who’s seen what can happen when homes aren’t properly cared for), I’ve learned a few tried-and-true tips that I share with friends and clients all the time.

So if your closets are starting to smell a little musty or you’ve noticed more condensation on the windows, this post is for you.

💧 First Things First: Your A/C Can Help (or Hurt)

Set your thermostat to 76–78°F and make sure the fan is on auto, not “on.” If the fan stays on continuously, it can actually push moisture around instead of removing it. 

If your system has a humidistat, turn it on. If not, be consistent with your A/C settings and consider adding a dehumidifier.

🌬️ Dehumidifiers Are Your Friends

Many homeowners use a plug-in dehumidifier in the laundry room and another near the closets that tend to get stuffy. If possible, use one that has a hose you can guide to a floor drain to avoid emptying a bucket every day.

🧺 Don’t Forget the Closets

Closets can trap moisture—especially those on exterior walls. Leave doors cracked and consider adding moisture-absorbing tubs if you’ll be away. I like DampRid products.

🚪 Keep Interior Doors Open

Let air circulate! Keep bedroom, bathroom, and closet doors open, and run exhaust fans after showers to reduce moisture buildup. I keep my ceiling fans on low in every room that has one -- keep air circulating!

👃 If It Smells Musty, Pay Attention

A musty smell is often a red flag. Check behind furniture, inside cabinets, and along baseboards. And please, don’t paint over mildew—it needs to be cleaned properly first.

🛠️ Bonus Tips for Seasonal or Snowbird Owners

• Use a smart thermostat to monitor humidity remotely.
• Place dehumidifiers on timers or with hoses for drainage.
• Ask a trusted neighbor to check in monthly.
• Take photos before leaving for documentation.
