Do i need two attic fans.

With an attic fan you can cool the attic to the same temperature as it is outside greatly reducing the house from heating as quickly. An attic fan is installed on the slanted side of your roof or on one of the gable sides of your attic. In a properly. Often being situated on the roof attic fans are often in need of repairing or replacing following hail storms.

However the utility of attic ventilation fans is actually quite a controversial topic. Whole house fans need windows and doors open and attic fans need lots of soffit vents to suck. Exhausting moderate amounts of attic air as solar fans do can counteract this reducing infiltration my calculations show it to be about right for a vented attic but either do the calculations or measure the pressures. There are really two categories of attic fans.

The whole house fan and the more. Because what happens is attic fans are so strong that they actually reach down into the conditioned space of your house and they do that by using the wall cavities and where the outlets and pipes come through the walls as places where they draw air from the inside of your house it. Good insulation reduces fan effectiveness. These fans are designed to remove excess heat from your attic which in theory is supposed to lessen the load on the air conditioning in your home.

For both fans to work well they need large exhaust openings in the roof for the moving air to exit. Quietcool attic fans work almost everywhere almost anytime. So if your fan is rated at 1500 cfm you will need about two feet of totally open space in your attic.

It doesn t matter if the ventilation openings are spread out as long as there is sufficient space for all the air to escape. Attic fans exhaust hot air from your attic to the outside. Do you need an attic fan if you have a ridge vent. Note that these two feet would not need to be one large opening.

Ok i would definitely not recommend an attic fan. The ventilation that controls moisture from condensation and regulates the temperature in your attic relies on air circulation. The downside of attic ventilation fans.
