How Solar Attic Fans Work

Creating constant airflow in an attic is the only way to guarantee this space stays between the recommended temperature range of no more than 10 to 25 degrees above the air temperature outside. This is especially important in the summer months.

A solar attic fan facilitates an efficient air exchange by venting out warm air that’s built up as a result of solar heat. This process creates space for fresh, cool air to enter the home and move through ducts from the attic to the living spaces.

As the cool air is moved through a combination of static and soffit vents by the solar-powered fan, a home’s overall temperature remains steadier, making the air conditioner less likely to overheat.
