Humidity

Sweating walls are one complaint hiding three problems: condensation from the air, water from inside the wall, or dry dark spots. The foil test sorts them in a day.

A sweating AC vent is a thermometer, not a failure: it reports that the dew point in your house is too high. The four causes by frequency and what to do in order.

Hurricane season is Florida’s humidity peak, and the real threat to your home is the power outage: no AC means no drying. How to build a buffer before the storm and recover fast after.

You cannot judge humidity by feel, and the decisions are expensive. A $10 humidity sensor answers the main questions. The catch is where you hang it and how you read it.

Humidity percent swings all day with the temperature. The dew point measures the water itself — and in a Florida summer it holds at 75–78°F for weeks. Here is how to read it.

Mold grows above 60% relative humidity — but at the surface it sits on, not at the gauge on your wall. Why the two numbers differ in a Florida home, and which one to trust.

Louvered doors, wire shelving, and the leather still blooms. Why Florida closets go damp, what overloading does to them, and how to fix it.

Wet glass in the morning is not what it means up north. Which side the water sits on tells you whether the house is damp, the AC is working, or the seal has failed.

Bigger is not safer. An oversized air conditioner cools too fast, short cycles, and leaves the house cold but damp. The signs, the causes, and the fix.

Cool room, sticky air. An AC not removing humidity is almost always short cycling from an oversized unit. How to spot the dry-drain sign and fix it in Florida.
