Understanding Attic Fans

Attic fans are integral components of a home’s ventilation system, designed to regulate the temperature and humidity within attic spaces. Proper use of these fans prevents a host of issues and contributes to an energy-efficient home.

Purpose of Attic Fans

The primary function of attic fans is to remove hot, stale air from the attic and draw in cooler outside air through attic vents. This process helps maintain an optimal temperature and prevent excessive humidity, which can lead to mold growth and structural damage.

Attic fans operate on a thermostat, automatically turning on or off based on the attic temperature, which ensures the space does not reach damaging heat levels.

Types of Attic Fans

There are mainly two types of attic fans: gable and roof-mounted.

Gable fans are installed in the gable vent of an attic and push the hot air out. On the other hand, roof-mounted fans are placed on the roof and directly expel hot air from the attic.

There are also solar-powered options, which are considered more energy-efficient as they harness the sun’s energy to operate.

Regardless of the attic fan model, ensuring proper attic ventilation is crucial for the effectiveness of the fan and the overall health of the home.
