How A Whole House Fans Work

So, you’ve heard that a whole house fan can cool your home—but how does it actually work? Don’t worry, it’s a simple concept with powerful results.

Imagine this: You head out for work or school, leaving your home sealed up for hours. As the day heats up, so does your house. Even when the sun sets and outdoor temperatures drop, the heat remains trapped inside, making your home feel hot and stuffy when you return. Since heat rises, the upstairs can feel even worse. Regular fans just move the warm air around without actually cooling your space.

Now, picture having a whole house fan from Central Valley Whole House Fans—here’s what happens! You open a few windows and switch on the fan, which is mounted in the attic, where the heat is trapped. The fan pulls the hot air up and pushes it out through the attic vents while drawing in fresh, cool outdoor air. The result? A comfortable home in no time, at just a fraction of the cost of air conditioning.

No more living in a hot, stuffy house! A whole house fan from Central Valley Whole House Fans is quiet, effective, energy-efficient, and affordable—the perfect solution to keep your home cool and comfortable.
