However what they do is to create massive amounts of air moving in the attic and hence it forms significant cooling. When there is air from the outside moving in the attic through cracks and holes, the temperature ultimately rises. At the same time, the air leakage in to the attic can bring along dust and grime which is not at all hygienic.

Most of the people use house fans as an alternative option to install air conditioner. One of the fans is the attic exhaust fan that can make the attic feel cooler than the still air.

The best option for an attic exhaust fan is to have one that is large enough and can fit into the ceiling area.
