What Is An Attic Fan?
An attic fan, sometimes called a mechanical attic ventilator or exhaust fan, is an open vent with a fan attached to it that pulls air from the home to the outside environment. It is usually connected to a switch or string that you can access from the top floor of your home. There are a number of benefits to having an attic fan in your home.
How it's Beneficial
Heat rises from the bottom floor of the house on up to the attic. An attic fan helps to route that hot air up and out of the home. An attic fan is ideal if you want to avoid unnecessary humidity in your house.
Energy Efficiency and Cost Savings
Attic fans are key to maintaining an energy-efficient home. If you allow rising heat to stay in your home instead of routing it up and out, your air conditioning unit will have to work harder to keep the house cool, reducing the AC unit's energy efficiency. An attic fan plays a part in keeping your energy bill down in hot summer months.
Ventilation of Any Fumes
Proper ventilation in your home is important in case vapors or gases are present in the air. The attic fan will help move any unwanted gas in the air out of the house more quickly, especially in cold seasons when you leave the windows of the home closed.
