What’s the difference between an attic fan and a whole house fan?
Attic fans are quite different. They’re installed up on a roof or through an exterior wall up in an attic. Whole-house fans need windows and doors open and attic fans need lots of soffit vents to suck cooler outdoor air up into the hot attic. Without this open space, the fans will not move much air.
Where do you install an attic fan?
Simply cut an opening in the roof, typically near the peak, and install the fan over the opening. Then shingle above and around the flashing just as you would for a standard roof vent or plumbing stack. In our case, we chose a gable-wall fan that was slightly easier to install because no shingles had to be disturbed.
How do I get hot air out of my attic?
Install electric ventilators and attic fans, which remove hot air from an attic. They have thermostats that turn the fan on at a recommended preset temperature of 100-110 degrees. Alternatively, install passive vents such as gable, soffit and ridge vents, which are openings in the roof that allow hot air to escape.

Should I cover my attic fan in the winter?

Closing your vents makes the attic space too warm and dry – dangerous conditions for mold as well as pests.

In most of the cases, the noise will appear due to some parts of attic fan getting old or by being worn out.
How often should my attic fan run?
Generally speaking, an attic fan should run as long as it takes to replace all the attic air with outside air. Usually, this takes roughly 15 minutes. However, you can calculate a much more accurate time by dividing the strength of your fan by the volume of your attic space.
Do attic fans turn on automatically?
An attic fan is normally automatic. An adjustable thermostat, which is included, turns the fan on and off according to the temperature. If you have a humidistat installed, it turns the fan on and off as well according to the humidity.
Do attics need to be vented?
In the winter, warm, moist air seeps into the attic from the living space below. Good ventilation allows the heat and moisture to escape. That keeps your attic dry and reduces ice dams. If you don’t see any attic vents on the roof or in the eaves, you need to add some.
