How Attic Fans Work

An attic fan is a type of fan that is placed in your attic to act as a whole house fan for proper ventilation. It encourages constant circulation of air throughout your home, reducing energy costs, and normalizing the temperature of your home. Many attic fans turn off and on automatically with a thermostat, so you don’t need to worry about when it is on or off. The attic fan may be mounted on the roof or a gable.

Better Air Quality

With the regular air circulation, you have better air quality in your home by using an attic fan. It continuously moves air in the attic, helping to reduce moisture and humidity and keeping the attic dry. This not only helps with the attic, but throughout your home, as poor air quality in this space can permeate throughout your house. You will notice the odors and stagnant air is no longer an issue.

Benefits for Your Roof

Your roof also gets some great benefits when you install an attic fan. The life of your roof can be extended because of improving the air and keeping an ideal temperature in the attic space. With the attic fan, temperatures in the summer and fall will drop and provide better insulation. If your attic were too hot, this would affect the roofing material and cause damage to it much more quickly than without the use of an attic fan. With better ventilation, you prevent heat build-up, benefiting your roof.

Reduce Moisture

Extra moisture and humidity is a problem in the attic as it can lead to mildew and mold, as well as rotting in the roof and framing of the attic. Installing an attic fan is the recommended way to reduce moisture and prevent these very expensive issues from happening to your attic. If you notice that roof nails are sticking out above the deck, it is usually a sign of too much moisture. In this case, you might still be able to prevent more damage by getting an attic fan and letting more air circulate.

Lower Temperature

Since heat rises, your attic is at risk of very high temperatures, which can damage the structure of the attic and the roof above it. In order to lower the temperature, you need to get some cooler air in there, but running your air conditioner can be expensive. As an alternative, an attic fan helps to lower the temperature from 160 degrees in the summer to a most 60 degrees. The best time to have the attic fan turned on is in the morning and evening when temperatures are below 80.

Reduced Energy Costs

Since you are not using your heater and air conditioner as often with the attic fan, you are also reducing your monthly energy costs. This is a great benefit to circulation and ventilation of air in the attic.

Attic fans are easy to use and install, with many of them running automatically based on the attic’s thermostat. Consider these many benefits when deciding if it is the right option for you.
