OVER 50,000 QUIET COOL FANS SOLD IN THE UNITED STATES!
The patented Quiet Cool system by QC Manufacturing Inc., is a combination of large fans that are installed in the attic. The Quiet Cool Fans hang from the attic rafters and connect to a ceiling grille via insulated ducting.
ALL OF OUR DUCTED FANS COME WITH A GRAVITY DAMPER SYSTEM TO INSULATE THE CEILING OPENING

The fans quietly suck cool outside air into your home, creating a cool breeze. The hot attic air is pushed out through your home's existing attic vents.
I installed your 4500 cfm, QC-4500B (aka: Quiet Giant) about 3 years ago and I have been wanting to send you guys a huge love letter ever since.
The quietness of this fan allows me to run it any time and as long as I want. It has transformed my ranch-style house...with the T-shaped halls...that didn't pass air even when the outside winds were blowing at 25mph...from a summer hot-box to an aerated, cool, delightful living space.
I am surprised how very often I pop it on, even if only for a few minutes, to clear the air in a room or in all the rooms.
Being able to move out stagnant air is something I've wanted for years and it was my lucky day when I spotted your website.
If they make me governor someday, I guarantee that this fan will be MANDATORY in ALL new home construction! Ha!
But seriously folks, especially in a hot, dry, low humidity area such as Denver, these wonderful fans would save people a fortune in AC bills.
THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU and THANK YOU AGAIN QC Manufacturing Inc. !!! Walter F.
Quiet Cool fans are certified to the California Energy Commission and have an "Gravity Damper" that creates a positive seal to isolate the attic air from the indoor air in cold weather climates!
NO ATTIC SPACE? NO PROBLEM!

PROVIDES COOLING 3 DIFFERENT WAYS
Quiet cool 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 fans can be very noisy. Not so with the these fans. Our fans are less than 0.4 sones each!
The attic can reach temperatures in excess of 150 degrees in the 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 a whole house fan remains uncomfortably warm during summer evenings and the upper floor of a multi-floor house is always warmer.
One or more Quiet Cool’s can be used to ventilate your home at any time of the year.
WHEN TO RUN YOUR FANS
Any time during the 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 the next morning.
We recommend you start by cooling the area (by opening a window) 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 Quiet Cool 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 Quiet Cool 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 Quiet Cool 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 QC-1500 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 THE QUIET COOL SYSTEM IF I LIVE IN COLD WINTER CLIMATE?
Quiet Cool Classic Fans come with a 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.
IS IT TRULY NECESSARY TO HAVE THE FANS EACH INSTALLED WITH THEIR OWN INDIVIDUAL OUTLET, PER THE INSTALL INSTRUCTIONS?
A circuit is a string of outlets on one circuit breaker that is located at the electrical panel. When we suggest each fan to have its own outlet it is usually on the same common circuit, which is usually an existing circuit in the general area. Each outlet is then controlled by a switch. If you don't want to have the ability to control each fan separately, than you can share two fans on each outlet. There is another way of wiring two fans on one outlet but it is confusing to people who aren't experienced in electricity, so we haven't mentioned that option. Normally you do not need to run a new circuit from the breaker box (electrical panel) to the attic location, but simply sharing an existing circuit. Our fans use small amounts of electricity.
PROPER FAN SIZE FOR YOUR HOME
Upon viewing our sizing chart, we recommend that you select (at a minimum), the "Better" level of airflow. The "Fair" category listed on the chart is often what other 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 recommended 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 can also be installed on a vertical wall instead of a ceiling, if there is adjacent attic space and sufficient attic venting.
HOW DO I CALCULATE MY EXISTING NET FREE ATTIC VENTING?
There are many different types of attic roof vents used in home construction. Common venting types are: Turbine or Whirlybird Vents, Static Vents, Flat Vents, Dormer Vents, Ridge Vents and Gable Vents.
Calculating your "Net Free" Venting:
A. First Measure Your Vents
Take total inches of the length x width of each vent to determine a rough estimate of your existing roof and attic venting.
B. Covert The Inches To Square Feet.
Use the total inches of your vents and convert to square feet by dividing that number by 144.
C. Are your vents screened? If you have screening material over your vents, then you need to cut the total area in half, since screens can reduce airflow by 50%.
Take the gross total area of venting, multiply that number by .50 to get your total "Net Free" Venting.
Here Is A Better Example:
A single 12" x 12" gable vent would be 144 square inches of venting. To convert to square feet, simply divide by 144 (since there are 144 sq. inches in one square foot). 144 divided by 144 = 1 sq. ft. If the vent is screened the cut that measurement in half which you give us 1/2 sq foot of net free venting.
This information is designed to be used only as a general guide. Consult with a licensed contractor or roofer to determine your net free venting requirements.
ARE YOUR FANS ENERGY SAVER RATED?
Energy Star Ratings do not exist for whole house fans. The US Dept. of Energy has never created an Energy Star category for whole house fans, however whole-house fans typically use about 1/10th the power of air conditioners, and they are relatively inexpensive to install. They can help you cut your air conditioning bill substantially.
DO QC FANS MEET THE CALIFORNIA GREEN BUILDING CODE REQUIREMENTS?
Our fans meet the requirements of the code. Section 4.507.1 of the Code applies to Whole House Exhaust Fans and requires openings in the ceilings to be insulated to a minimum value of R-4.2 with louvers or dampers. An interpretation of the code for ducted fans requires that the ducts be insulated to a value of R-4.2 which all of our ducted fans meet.
There is wording in the code that the sone ratings must be at or below 1 sone, but that part of the code does not apply to whole-house fans; that is for bathroom exhaust and ventilation fans. Although most of our fans are well below a 1 sone sound level, we chose to rate the sound level of our fans in decibels rather than sones which is traditional with the industry.
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.
