Quick Tip- Whole House Fan Timers vs. Remote

A remote system is available as an option for switching your fan system, however we believe that a hardwired timer combined with switches is the most convenient and most reliable method of wiring your QuietCool Fans.

The system can be a little tricky to setup and there is no automatic shut off on the remote like we have on the electronic wall timer. You can set the wall timer to automatically turn off after running the fans for a preset amount of time (for example during cool nights). When running more than one fan, install the electronic timer in conjunction with a Double, Triple or Quad wall switch depending on the number of fans in your system..

Sizing - How Many Fans Do I Need?

Generally speaking you should install one fan in a central location such as a hallway and one fan in each of the occupied bedrooms that are used for sleeping. The recommended amount of air flow (or CFM) should should be approximately 2-3 times the square footage of your home. So, a home that is 3,000 sq. feet should have the number of fans that when added together move between 6,000-9,000 CFM (cubic feet per minute) of air, while keeping in mind the aforementioned placement locations.

Exhaust unwanted smoke and odors QuietCool Whole House Fans Are Revolutionizing the Market!

The QuietCool Systems products are "Ducted Whole House Fans" that were devleoped based on a proven method of whole-house cooling that has been around for years.

It is the most versatile cooling and ventilating system on the market today!

It Cools. It Ventilates. It Exhausts and It's Quiet!

These exceptionally quiet fans can be installed in a single, or multiple-fan configuration and are designed to move large amounts of air per fan. Install one of the higher volume CFM fans in your hallway or a combination of a large fan and a lower CFM fans in each occupied bedrooms for maximum cooling.

Simply multiply the square footage of your home by 2-3 to calculate the total CFM (airflow) and number of QC fans that you will need to purchase.

Sizing your home for the proper amount of CFM's is important, since insufficient air flow will not allow for the desired minimum of ten air exchanges per hour, which is recommended by the Home Ventilation Institute.

Also, insufficient CFM may not produce an adequate breeze, which is needed to quickly cool the home, attic and skin temperature.

WHOLE HOUSE FANS COOL & SAVE ENERGY
QuietCool Fans Can Cut Your AC Cost 50%-90% Quiet Whole house fans cool by drawing cooler outside air in through your open windows which lowers the room temperature by as much as 10 to 20 degrees

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 fresh, 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.

QuietCool Fans Have A Built In Damper System To Seal The Fan Opening From The Attic During Cool Months QuietCool fans are 100% made in the USA and come with a 10-year warranty from QuietCool Manufacturing Inc.

There are no belts or motorized doors to wear out. The QuietCool motors have lifetime lubrication and are maintenance free!

QuietCool Fans Have Been Certified To The California Energy Commission As Meeting Applicable Efficiency Standards.

green product for a healthy home
home ventilation QuietCool Fans Are Good For The Environment According to the EPA, if too little outdoor air enters your home, pollutants can form to levels that can pose health and comfort issues.

One way to lower levels of indoor air pollutants is to increase the amount of outdoor air coming in. Using a whole house fan is the most effective way to ventilate and cool your home.

There are numerous sources of indoor air pollutants. Some of these pollutants include substances such as gas, kerosene, coal, wood, smoke & tobacco products; furnishings, asbestos-containing insulation, damp carpet, cabinetry or furniture made of certain pressed wood, household cleaning and personal care products, central heating & air conditioner systems and humidification systems; & outdoor substances like radon, pesticides, & other outdoor air pollution. Remember, if you do not allow fresh outdoor air to enter your home, these pollutants may accumulate to levels that may cause health and comfort problems.

In recognizing the energy saving, cooling and ventilation benefits of installing whole house fans, many energy or electric utility companies give rebates to homeowners who buy and install QuietCool Whole House Fans. See our Rebate Page for a list. Each company will have different requirements, please see their site for details and availability.

Whole House Fans & Attic Fans Are They The Same?
Attic fans and whole house fans are often thought to be the same. Yes, they both are installed in the attic and in similar ways provide cooling to your home. The truth is they are very different and understanding how these products work is important, so you can purchase the proper product to help cool and ventilate your home.

Attic Fan
Attic fans are installed in the attic near the gable vent and are designed to exhaust hot air from the attic space. Attic fans are designed to remove hot air from the attic space, but do not pull air from the living area. On hot days, the temperature in the attic can be well over 90-100 degrees. The hot attic air gets trapped in the attic, and attic fans can be effective in pushing the hot air out which in turn helps to cool your living space. Attic fans are thought to be helpful in extending the life of your roof structure and other components. Attic fans, especially the new gable attic fan with an energy saver motor, draws very little power, saving energy while working to cool your home. Attic fans can also be effective in reducing attic moisture during cold weather.

Whole-House Fans
A Whole-house system can be used instead of an air conditioner most of the year in most climates. Similar to attic fans, whole-house fans push hot, stale air out of the attic to help cool your home, office or building. However, instead of simply pushing the hot air out of the attic, a whole-house fan pulls cool air into the home through an open window and flushes hot air out of the home via your attic vents. Whole house fans cost much less to operate than air conditioning and are relatively easy to install. Whole house fans cool by providing air flow, ventilation, by lowering attic temperatures. Quiet whole house fans are also energy efficient and rebates are available from many energy or electric companies to help offset the cost of installing a whole house fan system. Also, make sure you order and install the proper number of whole house fans based on your homes' square footage.

California Title 24 Building Code and Whole House Fans & Ventilation
Based on the fantastic savings realized by homeowners on their electric bills by using whole house fans to cut air conditioner usage, California State Legislators have now recognized the benefits of whole house fans.

In May 31, 2012, The California Energy Commission, issued the following press release regarding Title 24 whole house ventilation More Efficient Buildings for California's Future. In summary, Title 24 will mandate that all new home construction in seven of California's sixteen climate zones will require that a whole house fan be installed to cool homes and attics with evening air reducing the need for air conditioning load. The proposed amended standards will be adopted in 2014. The new standard will also require 2 CFM of air flow per square foot of living space as well as attic venting requirements that will need one square foot of attic venting for every 375 CFM of air flow created by the whole house fan system. New home builders will need to increase the amount of attic venting to be in compliance with the new standard. The seven climate zones where the new law applies are zone eight through fourteen. Here is a link to the California Energy Maps.

The law also reads that where "whole house fans are required, only those whole house fans that are listed in the California Energy Commission Appliance Efficiency Directory may be installed."

Yes, QuietCool Fans are not only listed in this directory, but hold many of the top spots for energy efficiency!
