How to Keep Your House Cool During a Heat Wave

Keeping Cool Tip #5: Repair Windows and Doors
Windows and doors are a major source of heat gain in the house, so keep windows closed and locked and doors tightly closed to prevent cool air from escaping. Older single pane windows and doors without proper weather stripping are the worst culprits.
If you can’t replace your windows and doors with more energy efficient models, repair any gaps in or replace weather stripping around and under windows and doors. Also, don’t open windows at night unless the temperature drops to the mid-70s F or lower.
