Humid Summers and Your AC in Pensacola
Cooling a house is only half of the AC's job here. In Pensacola's humid summers, removing moisture matters just as much for comfort and for the house itself.
Request an AC technicianHow the AC dries the air
Moisture condenses on the cold indoor coil and drains away. The longer the system runs at a steady pace, the more water it removes.
Short cycling
An oversized AC cools the room fast and shuts off before much water is removed, leaving cool but sticky air.
Fan settings
With the fan on "on" all the time, water on the coil can blow back into the house. "Auto" lets it drain.
Leaky attic ducts
Return ducts with gaps pull in hot, humid attic air, adding moisture every time the system runs.
Signs to watch
Condensation on windows or vents, musty closets and mildew in bathrooms point to humidity problems.
Dehumidifiers
A whole-house dehumidifier removes moisture on mild, muggy days when the AC barely runs.
Storm season
After heavy rain or a storm, check for water in the attic or around the air handler, which can add to indoor moisture.
Get help
See humidity control.
Closets and storage
Closed closets and storage rooms get little airflow and can turn musty first. Leaving doors open a crack, or adding a small vent, helps air move.
Measure it
A simple digital hygrometer shows indoor humidity at a glance. If it stays high on a day when the AC has run for hours, something needs attention.
When you're away
Don't switch the AC off for a long trip in summer. Raise the setting a few degrees instead so the system keeps removing moisture while the house is empty.
