Proper Insulation - Shadows & Light
Save on Air Conditioning Bills with an Attic Fan
Attic fans are ideal in the South. Attic fans by themselves can reduce your upstairs temperature by 10 degrees in the summer. When used with your air conditioner, they can reduce your cooling costs by as much as 30%.
Super heated air rises and gets trapped in the upper stories of your home. An attic fan draws hot air out of the attic and releases it to the outdoors, giving your air conditioning system a much needed break.
By eliminating this excessive hear, attic fans can also extend the life of your roof shingles.
Traditionally installing an attic fan requires framing, roofing and wiring, however there are now solar powered attic fans on the market that eliminate the wiring aspect of the job. The solar panel sits literally on top of the attic fan cover and produces enough electricity to power the attic fan. Like traditional attic fans, the solar attic fans are controlled via a thermostat so no human control is required.
For longevity, it is best to purchase all metal fans with screens to prevent animals and birds from finding their way into your attic. In addition, make sure the attic fan comes with a Firestat sensor that automatically shuts the attic fan off in the event of very high temperatures (e.g. in the case of a home fire).
Attic fans are normally mounted the back of the roof, a couple of feet from the roof peak, or on the gable end of your house. Installation of an attic fan can be a big job. It’s best to hire a professional.
