Quiet Operation
These whisper-quiet and energy-efficient wonders are the #1 residential cooling & ventilation appliance on the market
How it Works
Our Whole House Fans utilize what already exists to create something offered nowhere else. Open two or three windows a few inches wide, turn on your QuietCool Whole House Fan, and experience fresh, cool air replacing your indoor air in 3-4 minutes. Your Whole House Fan will quietly pull air through the windows, into the attic, and out the attic vents giving you a cost effective way to keep your home cool and healthy.
Clean Air for the Indoor Generation
According to the American Lung Association, homes are like lungs, they need to breathe to make sure that fresh air comes in and dirty air goes out. To keep your home safe you have to introduce fresh, outdoor air to dilute these indoor pollutants. Turning on your QuietCool Whole House Fan means you no longer have to recycle your air, you can let your home breathe.

Vertical Adapter
Don’t have a conventional attic space above your living area? Utilize a Vertical Adapter and cool your home with a side attic. These adapters were created as some homes do not have attics above their living area. Some homes throughout the country have a side attic against their wall and only enough attic space for our Whole House Fans in this area. When this is the case, these homes can use a Vertical Adapter so our R5 Damper Doors can still operate successfully while offering the entire home cooling and comfort.

Whole House Fan Sizing Formula
As a rule of thumb, we apply a formula that calls for either 2, 2.5, or 3 CFM, which stands for “Cubic Feet per Minute,” per square foot of living space. A system with 2 CFM would be considered good, a system with 2.5 CFM would be considered better, and a system with 3 CFM would be considered the best. Use the calculator that can be found on this page in order to determine the amount of CFM that is required in your house. This mathematical formula will work every time, for homes of any size; just keep in mind that increased airflow is always preferable.
Considerations for Sizing
When sizing a whole house fan system, two extra factors must be considered:
Location: A good system should perform well in a coastal zone where the environment is cooler. The best system would make the most sense if located in a desert region where the environment is scorching during the day but chilly at night.
Ceiling Height: If the home’s ceilings are higher than 8 feet, make sure you size the system to account for the extra air volume within.
Which Whole House Fan is Right For You?

THE DREAM VENTILATION SYSTEM
ZONED (Multi-Fan) SYSTEM
Whole House Fan + Whole House Fan
A multi-fan zoned system provides the homeowner with complete control over their ventilation and cooling requirements. When sizing a zoned system, the overall CFM requirements must be met by adding the cumulative CFM of all zoned units (not each individual fan). When the entire house needs to be cooled, all zoned fans may be switched on at the same time. A zoned system, on the other hand, provides for individual bedroom management as well as more precise airflow control.
THE PERFECT SAVINGS TANDEM
Whole House Fan + Attic Fan
As a result, whole-house and attic fans are the ideal partner items for the same reason. The thermal mass of your home will be cooled by your whole-house fan the night before, allowing your house to stay cooler the next day. This fan can keep your attic cooler when the sun is at its fiercest. You might save a lot of money in the end! Your A/C will no longer cycle on and off, resulting in high utility costs.
