In the summer good attic ventilation reduces heat buildup. These fans may be controlled by a switch or a thermostat which detects heat build up in the attic space and automatically exhausts the attic space. Many homes already have some sort of gable vent since this type of attic ventilation has been the industry standard for many years. Fans and vents may be installed on the roof system that will draw the air out of the attic space and exhaust it to the exterior.

Intake vents located at the lowest part of the roof under the eaves allow cool air to enter the attic. In the winter warm moist air seeps into the attic from the living space below. The attic fans are fitted with thermostats that will switch on and off the fan depending on the homeowner s preference. A gable mounted fan is a good choice for attic ventilation since the fan can usually be installed in an existing opening in the gable wall.

An attic fan works by drawing in cool air to the attic space that pushes out the hot air through vents. For ease of installation this is the best option. Attic fan ventilation 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. That cuts cooling costs and prolongs shingle life.
