Attic fans are used to increase air circulation in homes and attic spaces, improving ventilation and energy efficiency for your home. Your contractor can help determine the best size and type of fan for your application, and plan for the most efficient installation method.

Do I Need an Attic Fan Installation?

If excessive heat builds up in your attic, installing a ventilation fan can draw cool air into the area to reduce temperatures, while whole-house fans draw outside air through your home to cool living spaces. Attic fans are powered by solar energy or through the wiring of your home, with vent fans requiring an exhaust outlet through the roof or a wall. A professional installation ensures that fan placement is secure with proper weatherproofing around vents, and that electrical connections are made properly and safely.

What Are The Benefits of an Attic Fan Installation?

Attic fans can dramatically reduce air temperature in stuffy attic spaces. Improving air circulation can prevent mold and mildew growth and structural damage from condensation. Reducing temperatures at your home’s roof can also extend the life of roofing, framing, and insulation materials and can improve the efficiency of air conditioning units. Fans designed for cooling living spaces can reduce the need for air conditioning in some climates by drawing cool air through the home during evening hours.

How Large of an Attic Fan Do I Need Installed?

The size of ventilation fan that is adequate for your home depends on the volume of your attic space and how much air needs to be moved each hour to efficiently reduce its temperature, while sizing for whole-house cooling fans is based on the square footage of living space. Your contractor or retailer can help you determine the appropriate size and power for a fan in your application.

What Types of Attic Fan Installations Exist?

Attic ventilation fans are designed to cool the attic area by drawing cooler air in from intake vents and pushing hot air out directly through an exhaust vent. These fans are installed on the roof or wall of the attic and may be electrically or solar powered. Whole-house cooling fans are designed to cool living spaces by drawing cool air in through open windows, expelling warm air through attic vents. These fans are installed in the floor of the attic, creating an intake through the ceiling of the upper level of the home. Cooling fans require electrical connections, and though they are not direct-vented to the outside, may require extra venting in the attic for adequate air exchange.

How Long Does an Attic Fan Installation Take?

Depending on the condition and accessibility of your attic, most ventilation fans can be installed within a few hours. More time may be needed to create and finish openings around whole-house fans or to install additional attic vents for exhaust. Extensive wiring upgrades or installations may require a few extra hours to establish a power supply and switches.

What Materials Are Needed for an Attic Fan Installation?

Most attic fans require standard carpentry and electrical tools to install, such as a saw, drill, tape measure, pliers, and screwdrivers. Providing an outlet for ventilation fans may require flashing and caulk or roofing cement, and electrical connections may call for wire, junction boxes and switches.

Do Attic Fan Installation Jobs Have Any Hidden Charges?

The condition and accessibility of your attic and roof are important factors in pricing the installation of an attic fan. If structural upgrades or roof and wall repairs are needed to accommodate the unit, the additional work may increase project costs. Likewise, if a power source is not already available for your fan, the ease with which an electrician can run wires and install breakers and switches will affect installation prices.

How Much Does an Attic Fan Installation Cost?

Prices for attic fan installations vary with the type of fan and its location, typically ranging from $116 to $365. Our Attic Fan Installation Price Guide describes how building size and fan types influence project pricing. Your installer or electrician can help determine the best cooling or ventilation method for your needs, and how the characteristics of your home will contribute to the complexity and cost of the job.
