An attic fan reduces the buildup of heat within an attic space. Keeping the fan on during the heat of summer can reduce heat-associated damage to roofing materials, reduce wear and tear on insulation and items stored within the attic, as well as decrease the amount of hot air from the attic that infiltrates into the home's living space. Most homeowners will want to hire a professional to do the installation, due to the need for electrical and carpentry work needed to complete the project.

Types of Attic Fans

Attic fans come in several types. Some are meant to be installed into the rooftop while others can be installed vertically into the wall. Some fans come with a built-in humidity control system called a humidistat. These can help to dispel excess moisture, further boosting the environmental and health benefits of having an attic fan installed.

Benefits of Attic Fan Installation

An attic fan costs less to run than operating an air conditioning system. The boost of energy efficiency that the air conditioning system receives when an attic fan is running can also reduce wear and tear on the HVAC equipment, resulting in lower repair and replacement costs. Attic fans can also extend the lifespan of the roofing materials of the home. The upper floor of the home will feel more comfortable while an attic fan is running. Some homeowners find that they only need to run the attic fan instead of the air conditioning system overnight, resulting in a significant savings on electricity costs.

Considerations for Installing an Attic Fan

Installing an attic fan in a place where there was already an opening for a vent will cost less than having to make a new opening. If there's already electrical wiring in the attic, this will hold down the project cost even further. Expect to need some additional materials such as plastic or metal flashing, caulk, plywood and electrical accessories to complete the project.
