Condensation. If condensation is on an interior surface:
•Raise the average temperature of the house one or two degrees and do not
block vents.
•Vent all appliances to the outdoors and run exhaust fans.
•Open patio door blinds for air circulation.
•Turn humidiers down as the temperature gets colder (unless used for medical
purposes).
If condensation is on an exterior surface:
•Close patio door coverings to reduce cooling of the glass surface by air-
conditioning.
•Remove or trim shrubbery close to windows to promote air circulation.
If condensation is between glass panes:
•Seal failure. Replace either the insulating glass assembly or the entire panel.
This determination should be made by a service representative.
