The patented Quiet Cool Whole House Fan system, by QC
Manufacturing, Inc. is a combination of large fans that are installed in the attic. The fans hang from the attic rafters and connect to a ceiling grille via insulated ducting.
The fans quietly sucks the cool outside air into your home, creating a cool breeze. The hot attic air is pushed out through your home's existing attic vents.
-NEW FOR 2010
-NEW Quiet Cool Fans are now California Energy Commission Tested & Certified For Airflow. New Increased Power-Higher CFM!
-NEW Quiet Cool Roof Fans (3 Models) - For Flat Roofs, Roofs With No Attic or Limited Attic Space (less than 24" high), Parapet Roofs and Commercial Applications.
The fans draw cooler outside air in through your open windows which lowers the room temperature by as much as 10 to 20 degrees F. Your open windows serve as intake “vents” which allow you to control the air flow by selecting how many or which windows you open.
Moving air, blowing through the whole house cools the occupants. The cooling breeze can lower the skin temperature by 5 to 10 degrees F.
The cooler air, after passing through the living space, is forced into the attic which pushes the hot attic air out through the attic vents. This can lower the attic air temperature by as much as 40 degrees F.
Quiet cool whole house fans are amazingly quiet and efficient! They are 100% made in the USA and come with a 10-year manufacturer warranty.
WHAT ARE WHOLE HOUSE FANS?
Whole house fans are a simple method of cooling your house. This method of whole house cooling has been around for years, however traditional whole house fans can be very noisy. Not so with the Quiet Cool Fans. Our fans are less than 0.4 sones each!
The attic can reach temperatures in excess of 150 degrees F. in summer, and that air, if allowed to remain undisturbed, will radiate heat down through the insulation to heat the living space. That is the main reason that a home, without the use of a whole house fan, remains uncomfortably warm in summer evenings, and that the upper floor of a multi-floor house is always warmer.
One or more QuietCool’s can be used to ventilate your home at any time of the year.
WHEN TO RUN YOUR FANS
Anytime of day that it feels cooler outside than inside your home, the system will work effectively. In the summer, this normally happens in the late afternoon to early evening, through to the next morning.
We recommend you start by cooling the area where you are going to be spending the most time for the next few hours.
In other words, create the coolest breeze where you are going to be. For example, in most family situations, the early evening is spent in the kitchen / family room area. Assuming this to be true, this is where you would start.
VERY IMPORTANT! OPEN A WINDOW OR DOOR PRIOR TO TURNING ON YOUR SYSTEM (It may pull ashes from the fireplace)
WHERE TO START
Begin by opening a window or two in the area you are going to be spending your time and turn on all of your QuietCool’s at once, for maximum cooling. The cooler air outside will immediately begin to create a breeze. Opening windows too wide or opening too many windows will lessen the cooling breeze you feel.
The breeze will flow through your home and make its way to each QuietCool you have in operation. This breeze will be
felt in the entire path, and will begin to cool the whole house. At the same time, the air brought in, will be sent to the attic.
This action will flush the very hot air out through the venting. When hot air is allowed to remain in your attic, it keeps your home hot even though it has cooled down outside. Removing the hot air and replacing it with cool air allows your home to cool off dramatically.
As it gets later in the evening, and even cooler outside, you can begin to open windows in other rooms of your home.
At bedtime, you should close all the windows except in the occupied bedrooms. This will provide each room with a cool breeze as long as desired. If you have a QuietCool installed in each bedroom as recommended, you can enjoy the breeze and your privacy with your door closed.
INDOOR AIR QUALITY
We should also stress the values of ventilating your home on a regular basis. Many private and government studies show that the air inside our homes is more polluted than the air outside. This is generally true even in industrial cities. Your QuietCool system can greatly reduce this problem by bringing in fresh air and exhausting stale polluted air all year round.
In cooler months, you can provide sufficient ventilation by operating one QC1500 daily for short periods of time without significantly cooling your home. The system can also be helpful in eliminating pet odors, burned food smells and smoke.
CAN I INSTALL QUIET COOL FANS IF I LIVE IN COLD WINTER CLIMATE?
Quiet Cool Fans come with an internal gravity damper system that is installed in the ducting to seal the fan when it's not in use. A magnetic cover (sold separately) can also be used to cover the ceiling grill.
HELPFUL TIPS
Don't run whole house fans when it is hot outside!
Cool your house in the morning and close all windows during mid-day.
Open only a few windows at first when it's starting to cool down in the afternoon or evening then later open more windows.
Close window shades and blinds during mid day to prevent sun from heating up home as quickly.
In the wintertime you may turn on the your Quiet Cool fan system at the warmest time of the day and bring in fresh warmer air to heat the home.
Traditional whole house fans leave a large opening in your ceiling that is not sealed! In cold weather climates warm air from inside your house will rise up into your attic and make contact with cold surfaces which can cause condensation. Quiet Cool fans seal automatically with an internal damper system to prevent warm air from entering your attic!
PROPERLY SIZE YOUR HOME FOR WHOLE HOUSE FANS
Upon viewing our sizing chart, we recommend that you select (at a mininum), the "Better" level of airflow. The "Fair" category listed on the chart is often what other whole house fan brands are recommending. The "Fair" level may not produce the cooling and ventilation results that homeowners are looking to achieve. To properly size your whole house fan system, it is recommened that you multiply the square footage of your living space by 2-3. For example: a 2500 square-foot house requires a combination of fans that produce approximately 7,500 CFM (2,500 x 3). Just to give you an idea, (2) QC-1500 in the bedrooms and (1) QC-4500 in a central location would be a possible configuration for this example. Other QC products can be combined to get the proper amount of CFM based on the size and layout of your home.
*The QC-1500 series of whole house fans can also be installed on a vertical wall instead of a ceiling, if there is adjacent attic space and sufficient attic venting.
WHAT DOES THE TERM FAN CFM MEAN?
A Fan's CFM (Cubic Feet Per Minute) is a measurement that indicates how much volume in cubic feet passes by a stationary point in one minute.

Contact us via Email to help find an installer We may be able to refer you to an electrician that is familiar with Quiet Cool whole house fans. If we don't have a referral in your area, you can contact your local electrician or contractor. If your electrician can install a ceiling fan, they should have no problem installing a Quiet Cool whole house fan system.
The installation cost is separate from the cost of the fans and should be paid to your installer directly at the time of installation. Installers are generally not available to come to your home for a site survey prior to ordering your whole house fans.
