Openings That Shouldn T Be There

• Seal air leaks to the attic and crawl space by weather-stripping around doors, ceiling fans, electrical fixtures, plumbing, heating ducts and pulldown stairways.

• Don't close off louvers in the attic and crawl spaces because they're needed for ventilation to prevent moisture build-up.

• The basement door should be kept closed. The basement is normally one of the cooler areas in the house; keeping the door shut will prevent cool air from mixing with warmer air throughout the house.
