What Causes Window Condensation in Alabama Homes?

Moisture, Temperature, And Alabama Weather

In most Alabama homes, condensation starts with too much moisture in the air, then shows up on the coldest surface in the room.

The state’s heat and moisture make condensation a common nuisance, especially when windows are not doing a great job separating indoor air from outdoor temperatures.
