Top Attic Fans | Buying Guide

An attic fan is not simply a fan that you plug into a wall outlet and place in your attic. Instead, attic fans, also known as whole-house fans, are attached to the floor of your attic and are designed to cool both your attic and main building using outside air.

Proper installation and placement of attic fans are key when it comes to maximizing efficiency. Attic fans are usually placed above a hallway or living space to provide air circulation for the entire house by creating a negative pressure air system within a building. Attic fans can also be placed on the roof directly above the attic, or an exterior wall to remove hot air and moisture from attics.

There are many benefits to having an attic fan installed indoors. However, choosing the most suitable attic fan for your home or business is crucial if you want to save money and cool your home during warm days and nights without having to run your AC. To help you decide, here’s a list of the top attic fans on the market today.
