Why Do My Windows Fog Up or Sweat in Brandon FL Humidity?

Why Windows Sweat In Brandon FL

Exterior sweating is common here, especially when the AC is running hard and the glass surface drops below the dew point.

• Fog that never clears between the panes.
• Water staining, peeling paint, or soft wood around the frame.
