Harics-

Excess moisture trapped in your attic can cause a variety of problems from rust and rot to increased bacteria and mold counts which can impact your respiratory health, not to mention the elderly, immune compromised, and the little children are particularly affected. Attic fans may spread the dust, molds, and bacteria if we do not keep the attic clean. Make sure that the attic is clean before you start using the attic fan.

There is quite a difference involving attic fans and whole house fans, in both form and function. Whole house fans are much larger in size and are placed somewhere in a central location of the house?s ceiling. These fans are an efficient way to cool a home, moving a decent amount of air through the house and up to the attic area. They can be run at all times during warmer months, but are most efficient when outside temperatures and humidity levels are not extreme enough to warrant using an air conditioner. This is because a whole house fan can only cool the interior of a house to the outside temperature and cannot dehumidify the inside. Another possible drawback to operating this fan is that they can also draw in outside dust and pollen.

Attic (or roof) fans are usually much smaller in size and are usually placed on the interior roofline of a house. These fans are intended to circulate heated air from the attic space to the outside, but can create negative pressures in a home.The pressure can: remove conditioned air from the house through ceiling leaks and bypasses; pull pollutants such as mold, radon and sewer gases inside the house and lastly, the pressure can back draft fireplaces, water heaters and fuel-burning appliances. Roof fans are generally not recommended for most house designs.

Are you talking about the turbines that spin on top of the roof, or a fan inside the attic. Is there a difference? I have a small house with two of this outsid
fans ---which only move when the wind turns them.
Anyone?

My Dad has an attic fan installed in his one story house. It's hooked up to a temperature sensor so that the fan comes on at a certain temperature and automatically turns off once the temperature has dropped by 10 degrees F. The fan blows the air out of the attic, via the existing gable shutter that were already installed when the house was built.

Is it worth it? He seems to think so. He claims his A/C runs about 20% less in the summer than it used to without the fan. He's on his 3rd summer in his house.

He bought me one for my house, but I haven't installed it yet. Our kit came with an adjustable gable shutter that closes automatically when the fan turns off, but I probably won't use it. The fan itself is 15" in diameter, and comes with everything you need to do the install (except the electrician).
