How To Keep Your House Cool Without AC (The Old Way That Costs Almost Nothing)

Your air conditioner is fighting heat you let into the house this morning. Eli, from an Amish stone farmhouse in Lancaster County with no central air, shows the old day-and-night rhythm that keeps a home comfortable through summer for almost nothing — and cuts your power bill way down. The rhythm: open the house on opposite sides at night for a cross-breeze to flush the heat, then close up and shade the windows by morning to trap the cool. Shade your west and sunny windows from the OUTSIDE (an awning, shutter, board, or sheet) — exterior shade stops about 80% of the heat a curtain can't. Run ceiling fans counterclockwise in summer (a fan cools people, not rooms). Vent and insulate that 150°F attic. Keep the oven off at midday, hang laundry outside, and plant a shade tree on the west side. Heat safety comes first: in a real heat wave, don't tough it out — seek a cool place, drink water, learn the warning signs of heat illness, and check on elderly neighbors. Fans are not enough above about 95°F. (The wet-sheet trick only helps in dry climates.) Comment below: have you been doing it backwards — open in the hot afternoon, shut at night? And are your nights cooling down where you are?
