Attic Fan Installation FAQs
Most homeowners install an attic fan because it significantly lowers the attic's temperature. When temperatures rise in your attic, that hot air can ruin your belongings, spill into other parts of your home, and reduce the life of your roofing materials. In the winter, attic fans can reduce attic humidity, which prevents mold, mildew, and peeling paint.
You can further protect your attic by insulating it. Insulating an attic costs between $1,500 and $3,500.
Homeowners install attic fans to reduce heat buildup in their attics, but cooling the entire home still necessitates central air conditioning or a similar system. Whole-house fans, however, are an alternative way to cool the entire home. Like attic fans, you install whole-house fans in the attic, which passes hot air out through attic vents. At $900 to $2,500, a whole-house fan installation costs more than the cost to install an attic fan.
Depending on the fan type and how it’s mounted, you may need to hire more than one pro. You’ll need to hire a roofer or carpenter when creating new vents or adding a fan to the roof. If the unit is electric, hire a licensed electrician to handle the installation.
In addition, the same pros also repair attic fans, with the cost to repair attic fans coming in around $200 to $430.
