Don’t underestimate the cooling power of fans, especially on warm, dry days when the house is stuffy. Even several fans running at once use only a fraction of the power consumed by a central air conditioning system.
- Use inexpensive box fans to circulate air through your house. For best results, note the direction of the prevailing winds, and position the fans in windows — one blowing in and one blowing out — to assist the wind.
- A ceiling fan placed over your bed can keep you comfortable at night by continuously circulating air.
- A whole-house fan (usually installed in the attic) will keep air moving throughout the house, pulling in cooler air from below and exhausting hot air above.
