Let’s see When You Should Run Your Attic Fan

If your attic has construction debris, dust and pollen

If your attic has a lot of construction debris, dust and pollen, it's probably time to switch it on. Dust is more than just unsightly. It can cause allergies, respiratory problems and asthma attacks. In fact, dust is a fire hazard too.All those tiny particles of flammable material can easily combust when exposed to heat sources like light bulbs or furnace filters.

If the humidity is high

Even if you haven't used your fan for a few days, if the humidity is high, switch it on. As mentioned above, high humidity can cause mold and mildew to grow in your attic, which could lead to serious health problems for those living in the home. It also causes wood to rot faster and paint to peel off walls more quickly than usual. High humidity will also cause wallpaper bubbles and condensation on windows or walls that are not properly sealed with weather stripping tape.

During the summer months, run the fan at night to push the cool air in from outside

  • During the summer months, run the fan at night to push the cool air in from outside. When you run it at night, you’ll be able to save on your electric bill and keep your house much cooler than if you didn’t run it at all.
  • In the morning, turn on your attic fan when you wake up or within an hour of getting up so that the cool air can circulate throughout the house while everyone is still sleeping. This will help lower temperatures in time for when everyone wakes up and gets ready for their day.
  • If it’s a hot afternoon or evening during spring or fall, turn off your attic fan because it won't make much difference at those times.

Turn on the fan when it's hot outside

The main reason to turn on the fan is to help keep the air dry. When you turn on the attic fan, it will draw air up through your attic and out through a vent in your roof. This helps keep moisture from collecting inside of your home, which can cause mold and mildew issues if left unchecked. In addition to keeping mold at bay, turning on an attic fan can help circulate air throughout your homeand circulating air helps keep rooms cool!
