Boise Attic Fans
We just returned from the ACI conference. One of the seminars touched on a timely topic of attic ventilation. It seems that every where we go, Home Depot, Lowes or even Costco; attic fans and solar attic fans are on display. The truth about attic fans is that they just don’t work as well as you may think. In fact, they will make a home more energy inefficient and they increase the chance of carbon monoxide entering your home. Some homeowners swear their attic fan makes the upstairs of their home cooler in the summer. They’re probably right but not for the reason they think. Attic fans move a tremendous amount of air and studies show that about 20% of the air comes from the INSIDE of the home. The attic fan is moving cooler air from the lower portions of the home to the upstairs but unfortunately it keeps moving the air into the attic and then outside.
