Are gable fans Effective?

Based on our industry experience, the answer is, yes. Attic fans do really work. They will help to circulate air in your attic and ventilate the space so that it stays closer to the outside temperature.

What is the purpose of a gable fan?

The gable vents turn into intake vents and bring in warmer air to the attic space. Some attic fans or whole-house fans are too powerful for the attic. If the negative pressure they create by exhausting attic air is strong enough, they can draw conditioned air from your living space into your attic, and then outside.

When should I turn on my gable fan?

Cooling Your Home Often you can feel the heat if you touch the ceiling that is adjacent to the attic. If you feel that heat radiating into the room near your attic, it is usually time to turn your fan on.

Do attic fans help keep the house cooler?

Attic Fan problems Even though an attic exhaust fan can incrementally lower the temperature of a very hot attic, using a fan does not stop the source-radiant heat. During the day, any cooler air brought in by the fan will be heated up immediately by the surrounding structure. Most fans cannot keep up.

Will attic fan help in the summer?

Typical attics will reach 120-150 degrees during the summer. An attic fan can help lower that temperature by up to 50 degrees, which translates into up to a 5 degree lower temperature inside your home.

Do attic fans use a lot of electricity?

Is a gable fan better than a roof fan?

Should attic fans run all the time?

If your attic fan seems to be constantly running, it would be a good idea to bring in a professional to check it out and make sure it’s still working properly. If the “switch on” temperature is set too low, you can bet that the fan will run all summer long and create a noisy disturbance.

Can you run an attic fan all day?

Run the Fan all Day Run the attic fan during the daylight hours during warm summer weather. Sunlight on a roof produces heat in the attic. Running the fan when the energy of the sunlight is striking the roof removes the heat that accumulates in the attic.
