Cooling Your Home With Attic Exhaust Fans

Cooling Your Home With Attic Exhaust Fans

Electrical fans are the most common and the most efficient. These are usually installed on the roof or gable wall, and they’re hardwired into the electrical system. Electric fans are often controlled by a thermostat and turn on when the attic reaches a specified temperature. For example, if the thermostat is set to 90 degrees, the fan turns on when the attic reaches 90 degrees and remains off otherwise.

Wind- Powered Turbines are another option. Have you ever seen the metal, rooftop-mounted fans that spin with the wind? These wind-powered turbine fans, affectionately known as whirlybirds, are a favorite for homeowners looking for a passive, low-cost option. As long as the wind is blowing and it does not need to blow hard and they are moving the air without affecting your electric bill. Their passive nature makes them less powerful than electric or solar fans, but they are still remarkably effective.

Solar fans are similar to electric fans, but instead of plugging into your home’s electrical system, they have integrated solar panels and run on solar energy. They’re not usually controlled by a thermostat, but rather run continuously as long as the sun shines. This means adequate and unobstructed sunlight is necessary in any location you are considering. There are many different models out there.
