How to Use an Attic Fan To Lower Electric Bills

Hot air rises, right into your attic and stays trapped there. The heat trapped in your attic will raise the temperature in your whole house. The higher house temperature, the harder your air conditioner has to work and that will raise your electric bill.

Instructions

1. 

   Choose the right size attic fan. When purchasing your attic fan be sure to know how many square feet your house is. Make sure the attic fan is large enough to remove the hot air from your attic to save the most money on your electric bill. The biggest money saver is a solar attic fan.

2. 

   Install your attic fan at the peak of your roof. If it cannot be installed at the peak, install it as close to the peak as you can. Installing an attic fan at the peak of your roof will allow for the most hot air to be removed and cooler air to be re-circulated inside of your attic.

3. 

   Use your attic fan especially during the day when the heat from the sun beating down on your roof really heats up your attic. An attic fan can lower the temperature in an attic by 45° to 50°. Lowering the temperature in your attic by 45° to 50° will lower your electric bill by 20% to 25% in the warm weather months.

Tips & Warnings

• Added bonus of using an attic fan: It will help to prevent damage to your roof caused by the heat.

• During the cold weather months be sure to cover your attic fan so the heat won't escape from your house. NEVER use an attic fan that is covered.
