## Signs Gulf Humidity Is Winning Inside Your Home

01

### Clammy air with the AC running

The thermostat says 74 but the house feels sticky. The AC is cooling the air without pulling enough moisture out.

02

### Musty smells and mold spots

Closets, bathrooms and the corners of a closed-up beach house are usually the first places mold shows up.

03

### Empty homes that come back damp

Second homes and rentals left empty for weeks can build up moisture fast if the AC is off or set too high.

## Humidity Control in Foley and the Beach Towns

Gulf air can keep a house damp even while the AC runs, especially if the system is oversized or the home sits empty for weeks. Contractors we connect you with measure indoor humidity, fix airflow and duct leaks, and install whole-home dehumidifiers that tie into the ductwork. For second homes and rentals, they set up settings that keep the house dry while no one is there.

> **Why humidity matters more than you think**
> 
> **Mold growth** needs moisture more than heat. When **relative humidity** stays above about 60 percent for days, mold can start on drywall, fabric, cabinets and inside closets. In a closed-up coastal home in July, that can happen fast.

## Signs Your Home Has a Humidity Problem

-   The air feels cool but clammy or sticky
-   Condensation on windows, especially early in the day
-   Musty smell in closets, bathrooms or when you first open the house
-   Mildew spots on walls, grout or furniture
-   Warped wood floors or doors that stick
-   A **hygrometer** reading above 60 percent

## Why a House Stays Humid With the AC On

An AC removes moisture as air passes over the cold coil. When that process is cut short, humidity stays high:

-   **Oversized AC:** cools fast, shuts off before it has dried the air, and short cycles
-   **Thermostat fan on ON:** water on the coil blows back into the house between cycles. Set the **fan setting AUTO** instead
-   **Duct leaks:** returns in attics and crawlspaces pull in hot, damp air. **Duct sealing** helps
-   **Crawlspace moisture:** raised and river homes with a poor **vapor barrier** feed damp air into the house
-   **Raised setpoints with no dehumidification:** an empty home with the AC barely running

 for the full list and fixes.

Common fixes, from the simplest to the biggest:

| Fix | What it solves | Best for |
| --- | --- | --- |
| Thermostat fan on AUTO | Stops coil moisture blowing back into the house | Every home |
| Blower speed and airflow adjustment | Longer, drier cooling cycles | Systems that cool fast but leave the air clammy |
| Whole-home dehumidifier | Removes moisture even when little cooling is needed | Second homes, rentals and houses that stay above 60 percent |
| Right-sized, variable-speed replacement | Fixes an oversized system at the root | Older oversized systems due for replacement |

## Whole Home Dehumidifier Foley AL

A **whole-home dehumidifier**, also called a **ducted dehumidifier**, ties into your ductwork and dries the whole house to a set target, whether or not the AC is cooling. It drains automatically and runs quietly out of sight. It is often the best fix for raised beach homes, river homes, and second homes that sit empty. See

.

## Humidity Settings for Vacant Homes

Never turn the AC off in an empty beach house in summer. Leave it running on a raised setpoint so it keeps pulling moisture out, keep the fan on AUTO, and consider a dehumidifier with a humidity target. Watch the **dew point** and humidity remotely with a Wi-Fi sensor. A **raised beach house** that sits empty for weeks benefits most from this setup. Our

Questions Callers Ask

## Humidity Control Questions From Foley and Beach Callers

### What humidity should my house be?

About 40 to 60 percent relative humidity, and ideally under 55 percent on the coast to discourage mold and dust mites.

### Why is my house humid even with the AC on?

Common causes are an oversized AC that short cycles, the thermostat fan set to ON, duct leaks pulling in damp air, or a home that simply needs more dehumidification than the AC provides.

### Should I turn the AC off in an empty beach house?

No. Leave it running on a raised setpoint so it keeps removing moisture. Turning it off lets humidity climb, and mold can start within days in summer.

### Do I need a whole-home dehumidifier if I have AC?

Not always. If humidity stays above about 60 percent with a properly sized AC and correct settings, a whole-home dehumidifier is worth pricing.

### Is a whole-home unit better than a portable dehumidifier?

It covers the whole house quietly, drains automatically and has no bucket to empty, which matters in homes that sit empty.

### Should my thermostat fan be ON or AUTO?

AUTO. With the fan on ON, water on the indoor coil can blow back into the house between cooling cycles.

### Can leaky ducts make a house humid?

Yes. Return ducts in attics and crawlspaces can pull in hot, damp air. Duct sealing often helps humidity as much as comfort.

### Can I monitor humidity when I am not there?

Yes. Wi-Fi humidity sensors and some smart thermostats send alerts to your phone. A contractor can help set them up.
