Improve home insulation. Seal doors, windows, and close fireplace flue. Close blinds or drapes on sunny side of house. Add window awnings. Keep air filter clean. Do not block airflow with drapes or furniture. Ventilate attic (high temperature levels add to normal cooling load). Try not to use heat producing appliances during the hottest part of the day. Turn lights, radios, televisions, and other appliances off when not needed. Keep heat registers and cool air returns closed or blocked off so cooled air won�t escape. Use a vent fan in cooking, laundry, or bathing areas to pull out heat and moisture near its source.
