Attic Exhaust Fans

Attic exhaust fans are absolutely crucial to keeping a healthy home. The main purpose of attic exhaust fans is to provide ventilation to help control the temperature in your attic.

 

Attic Exhaust Fan

Attics can collect heat, increasing your cooling costs in the summer, and moisture, which can result in mold, but these issues are remedied by installing an attic exhaust fan.

How Attic Exhaust Fans Work

Installed in your roof, an attic fan draws heat from your home and attic and pushes it outside, while pulling cooler air into the space. Think of the exhaust fan in your bathroom: it works in much the same way. However, attic fans aren’t all created equal. there are a variety of choices depending on your home’s needs.

Look for fans made of metal, which are the most durable, and that incorporate a screen to keep insects and other pests out. Fans may be installed on your roof top or at a gable-end.

Traditional Attic Fan

For many homes, a traditional fan suffices to cool the attic. You’ve seen these space-aged, dome-shaped fans that are driven by a belt. A drawback is that they leave an opening in the roof, which allows cold air to infiltrate in the winter. They can also be loud and require frequent maintenance as the belt can wear out.

Electrical Attic Fans

Electric fans can move large volumes of air. Many include thermostats that help save energy. They are more difficult to install than traditional attic fans because they require wiring.

Solar Attic Fan

Save on operating costs by using a solar powered attic fan. However, efficiency can diminish if there is not enough light to power it.

Wind-Powered Fan

If you live in a windy area and are seeking an environmentally friendly attic exhaust fan, consider the wind-powered fan. Wind blows the turbine vent, which in turn generates an air current that cools your attic.
