AirSmart Whole House Fan System


When whole house fans are turned on, the fans 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 Fahrenheit or more.
When using a 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 is the case, it is where you would want to start cooling. As it gets later in the evening, and even cooler outside, we recommend opening more windows in other rooms of your home.
Then, when it is time to sleep, 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. Remember when using a QuietCool system to be sure not to open too many windows or open any single window too wide. 3-6’’ and just a few windows will suffice to make your home a fresh-aired paradise.


Open a few windows any time it’s cooler outside than inside, typically in the morning and evening

Turn your QuietCool fan on by setting the speed and timer.

QuietCool pulls in cool, fresh air from outside and expels hot, stale air out attic vents.

Your home has now been made cooler, healthier, and more comfortable.


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. As it exhausts the stale indoor air out through the attic, it will also pull cooler outdoor air through and push it through the attic vents. This in turn causes 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. At bedtime, leave windows in the home open in rooms you want to cool. This will provide each room with a cool breeze as long as needed. If a door must remained closed for privacy and more ventilation is needed, a Zone Air Pathway can be installed in your system.
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.


We know that a QuietCool Whole House Fan can quickly exchange the air in a home. Properly sized, a QuietCool system will fully exchange the entire air volume of a home 15-20 times per hour, or about one full air exchange every 3 to 4 minutes. This can drop the indoor temperature to the same as outdoors, for just pennies–saving energy and clearing stale air out of your home. The long term benefit, though, is Thermal Mass Cooling.
When cool air is continually being pulled past your home’s walls, floors, furniture and out through the attic, it wicks away heat energy that has accumulated during the day. Not only does the temperature of the air in your home drop, but also the temperature of the whole mass of your home! Run on low all night long, your fan can greatly reduce your home’s core temperature and give it a head start for the next hot day. When the sun starts to beat down on your house it will take longer for it to raise the temperature of your attic, the walls, and eventually, the interior of your home. The longer this takes, the less your A/C will have to run. Some days you may find that your A/C barely turns on before you are able to turn it off again and turn on your QuietCool. Not only that, instead of recycling hot, stale ambient air through a closed-loop air conditioning system, the QuietCool system is exchanging hot, stale ambient air with fresh, cool outside air, through an open-loop whole house ventilation system… and at a fraction of the cost of running an air conditioner.


A “cool mass” home does not reheat as much or as quickly as a “hot mass” home. Within a day or two of installing a QuietCool system, homeowners are amazed when they come home after work and their house is still cool from the night before!
The reason the home can remain cool is because the mass of the home had been cooled by a QuietCool system and thus did not reheat as rapidly as it typically would.
QuietCool is truly a revolutionary product that allows people to save money by turning their A/C off and turning their QuietCool system on!
