Attic fans are intended to cool hot attics by drawing in cooler outside air from attic vents (soffit and gable) and pushing hot air to the outside. However, if your attic has blocked soffit vents and is not well-sealed from the rest of the house, attic fans will suck cool conditioned air up out of the house and into the attic. This will use more energy and make your air conditioner work harder, which will increase your summer utility bill.

You don’t want your unfinished attic cooled by your air conditioner. To prevent this, make sure that the attic is insulated properly and that it is well-ventilated using passive vents and natural air flow.  For more information on how to make sure your fan is working properly, follow the link below.
