A whole house fan helps cool your home by drawing in fresh outdoor air and exhausting warm indoor air through the attic. These fans are highly energy-efficient, using significantly less electricity than an air conditioner. They work best in the evening or early morning when outdoor temperatures are cooler.
By improving ventilation, they reduce indoor heat buildup and lower reliance on traditional AC units. Whole house fans also help remove odors, stale air, and humidity, creating a fresher indoor environment. Proper attic ventilation is essential for maximizing efficiency and preventing moisture-related issues.
When used correctly, a whole house fan can lower cooling costs and enhance home comfort.
