When the QuietCool whole house fan is turned on, the fan will pull the cooler outdoor air into your home, through your windows, across your living space, into the attic, and out the attic vents replacing the hot stale air. This helps cool the home and attic by up to 30 degrees, and sometimes more, allowing the home and attic to stay much cooler the following day.

When using the QuietCool whole house fan, we recommend starting by cooling the area which will be most occupied. For example, in most family situations, the early evening is spent in the kitchen and family room area. Assuming this to be true, this is where you would want to start cooling.

The cool breeze begins when a window or two is opened and the QuietCool fan is turned on. The cooler outside air will immediately begin to create a breeze inside the home making the homeowner feel up to 10 degrees cooler, and sometimes more, instantly.

This breeze will be carried through your home to
each QuietCool whole house fan that is on and in use;
thus beginning the cooling process. At the same time,
the cooler outdoor air will be brought into the attic
and pushed through the attic vents causing the hot
stale air in the attic to be exhausted. Exhausting the
hot air inside your attic will allow your home to
stay cooler throughout the day.

As it gets later in the evening, and even cooler
outside, we recommend opening more windows in
other rooms of your home. Then at bedtime, close all
the windows in the home except those in the
bedrooms that are occupied. This will provide each
room with a cool breeze as long as needed. If a
QuietCool is installed in each bedroom as we
recommended, the homeowner can enjoy the breeze
and your privacy with your door closed.

Note: When using the QuietCool system, be sure to
not open too many windows or open any windows
too wide, as this will lessen the cooling breeze that is
felt. There is a “sweet spot” when window opening(s)
throughout the home are “just right” to cause a nice
active breeze to be felt at each open window.
