Do Not Get Confused…..

Of the difference between an attic fan and a whole-house fan… They may seem the same, but there is a big difference!
Yes, the similarity is they both have move air around, but that’s all they have in common!

The difference ….

Whole House Fans - Is located in the ceiling of your home. In some cases; often rare they could be located in the wall. Such as a hallway, or some place that is a central location. Anyhow, the fan is always located in the highest ceiling or wall, and is oriented to blow air directly.
The whole house fans are designed to pull air through the house and exhaust the air into the attic space.
Attic Fans - Are smaller and is designed to move air in the attic outside and through the vents; to cool down the attic. They are not designed to move air throughout the home like the whole house fan.

The Logic Behind the Attic Fan is Simple:

When you replace the hot air from the attic, which can range from 140℉ - 170℉ with the inside air that could be 85℉ - 95℉ the attic will become cooler than without an attic fan.
On default, unlike the whole house fan, the attic fan exhaust the air outside. Because the air is exhausted outside than the whole house will stay cooler.

So…. If you have a whole house fan then it's highly recommended to also get an attic fan installed.
