Florida Humidity Control
Humidity / Dehumidifier Sizing Calculator
What indoor humidity should my Florida home have?
A practical indoor humidity target for many Florida homes is about 45% to 55% relative humidity. If the home stays above 60%, feels sticky, smells musty, or cools without drying, the AC runtime, sizing, airflow, ducts, drain, and dehumidification options should be reviewed.
Humidity / Dehumidifier Sizing Calculator FAQs
Is 60% humidity too high inside?
It is high enough to investigate if it is common, especially with musty odors, sticky rooms, or visible moisture.
Why is my house humid when the AC is cold?
The system may be oversized, short cycling, low on airflow, duct-leaky, dirty, or not managing latent moisture well.
Do I need a whole-house dehumidifier?
Maybe, but first confirm AC size, runtime, airflow, ducts, drain, and infiltration.
