Cool Your Home With A Breeze Of Fresh Air

The Quiet Cool fan systems the best choice for homeowners based on energy savings, high quality, value, ability to move a large volume of air (1500CFM each), ease of installation, aesthetic appearance, versatility, and above all, quiet operation.

The Quiet Cool multi-fan and multi-location system is designed to cool and ventilate your entire home. More versatility means more convenience and more effective results. The Quiet Cool cools people in 3-ways: house, attic and people. It works amazingly well in any home with an attic.

The Quiet Cool is the most versatile and innovative home cooling and ventilation system on the market today. Each fan in the system can be controlled individually so you can close your doors (i.e. in the bedrooms) while the fans operate to gain privacy. Individually controlled fans will also allow you to control how much airflow comes into the home, simply by turning each of the fans on or off.

The reason that these fans work so quietly is that the fan motor mounts to the rafters, away from the living area to keep the noise so low. Nothing else on the market can compare. These units are so quiet you can talk, read, sleep, or watch TV while operating.

Fan noise is a very important consideration when purchasing whole house fans or circulating fans for your home. According to the U.S. Department of Energy, "When shopping for home circulating fans, be sure to test the fan for noise. Listen to the different qualities of each fan’s sound. Fans also will be marked with their rated noise level, measured in “sones.” Very quiet fans are rated at 1.5 sones. Some are so quiet, they’re rated as low as 0.5 to 1 sones." (the Quiet Cool Fans are less than 0.4 sones).

Other whole-house fans often generate noise of 3.0 sones and greater, preventing them to be installed in key areas such as bedrooms etc. Based on these figures, these fans generate over 7 times the noise compared to the Quiet Cool system. To give you an idea how quiet 0.4 sones is compared to other familiar sounds for example, 8 sones sounds like a busy freeway, 3.0 to 4.0 sones sounds like a Television or Radio, 2.0 sones sounds like noise in a calm office setting and 1.0 sones like your refrigerator.

There is no framing needed with the Quiet Cools. Some custom wood framing is normally required with whole-house fans sold elsewhere.

These fans are so effective in cutting your electric bill that most utility companies provide you with a substantial rebate for installing whole house fans in your home. You can operate the fans for pennies per hour compared to dollars for central air conditioning. For an average 2,000 sq. ft. in California in 2003, the cost to run a central air conditioner is $1.40 per hour. By comparison, the cost to run a typical whole house fan is about $0.06 cents per hour. By turning your air conditioner off for 3 to 9 hours a day during the evening hours, you can save up to $1,800 per year on your electric bill depending on the climate in your area.

Order your fans today and begin to enjoy year round whole house ventilation and realize a substantial savings on your electric bill during summer months.

FAQ’s (Frequently Asked Questions)

1. What is whole house cooling?

A whole-house fan is a home improvement product used to cool and ventilate your home. Whole house cooling is not a new concept. It has been around for many years. A whole-house fan works by exchanging the hot air, moisture and odors in your house with fresh cool air that is pulled in from the outside. It provide an effective way to achieve efficient attic ventilation and create a cool breeze inside your home. These house fans work quickly, quietly and efficiently.

Whole-house fans use far less energy than air conditioners; they cut cooling costs, save energy and save you money. Whole house fans typically use about one-fifth to one-tenth the electricity of comparably sized air conditioners, and they are relatively inexpensive to install. Used correctly, they can help you cut your air conditioning bills substantially.

Simply by flipping a switch, your whole-house fans will instantly begin to pull cooler outside air through open windows like a vacuum and send hot indoor air out through your existing attic vents. It can lower the temperature in your home by five degrees in just a few minutes. We recommend installing the fans on wall timers or on a remote, so you can have the fans turn off automatically or with a click of a button.

You control the air flow by selecting which windows and how many to open. These open windows act as an intake, to suck in cool fresh air. Yes, you can install these fans in your bedrooms and close your bedroom door. Simply open a window and the fresh cool air will be pulled into your room.

By installing Quiet Cool fans in each of your bedrooms and in other common areas of your home, you will create a cool breeze of moving air. This moving air blowing through the 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 air out through the attic vents and lowers your attic air temperature by as much as 30-50 degrees F. The attic can reach temperatures in excess of 150 degrees F. in the summer and that air, if allowed to remain undisturbed, will radiate heat down through the insulation to heat the living space. Homes with tile roofs will even see a greater amount of heat retention.

This is the main reason that a home without the use of whole-house fans, remains uncomfortably warm in summer evenings, and the reason that the upper floor of a multi-floor house is always warmer.

2. What is the difference between a whole house cooling fan and air conditioning?

Whole house cooling brings outside air into your home to cool it, while flushing out the warm air and ventilating the house at the same time. Air conditioning takes the existing inside air and keeps recycling it and cooling it slightly each time it is recycled. No stale air is removed in the process.

3. Can I use both an air conditioner and a whole house fan?

YES, definitely, but not at the same time. The whole house fan should be used when the outside air temperature is cooler than the inside temperature. The air conditioner is used when the reverse is true. Normally, the whole house fan would be used in the evening, night and early morning hours, and the air conditioner during the heat of the day.

4. Why must a window or windows be open?

A whole house fan sucks a large volume of air out of the house creating a vacuum of air and blows it out through the attic. If no window is open, a negative air pressure is created which will draw air in from a fireplace, or other vents.

5. What type of whole house fan should I buy?

The Quiet Cool systems are the right choice for any home. There are several different fans on the market. Compare before you buy. Look at installation issues, custom wood framing, noise levels, and for moving parts that can wear out or need maintenance. We feel that you will agree that the Quiet Cool is the best whole house fan on the market. We encourage you to find a neighbor or a friend that has a traditional whole house fan installed and have them run it for you, so you can hear the high noise level for yourself. Ask other manufactures if they recommend installing their products in your bedroom and running the fans at night while you sleep or watch TV. Our bet is that they won't recommend this with their products.

6. Why is the Quiet Cool the most innovative whole house fan on the market?

The Quiet Cool fans can be installed almost anywhere because the entire mechanism hangs in the attic and the only visible part is a small, attractive ceiling diffuser. The diffuser can also be mounted on a wall in areas where attic access is not available (for example a room with a vaulted ceiling) directly above a room. Our fans can be easily installed in the framing stage or after. Installations can be easily performed by any licensed electrician or contractor in your area. It's as easy as wiring a ceiling fan! There are no mechanical parts other than the fan motor. These fans are maintenance free!

7. Why is a quiet whole house fan important?

Years of experience have shown that if a whole house fan is noisy or whining, we won’t turn it on while watching television, reading a book, carrying on a conversation, or sleeping. As the outside air cools during the evening hours, this is the time when whole house fans are designed to be used. The Quiet Cool fans are so quiet, you can use them all night long.

8. Why is the Quiet Cool fans the easiest whole house fan to install?

The Quiet Cool fans do not require any carpentry or framing work to install, as seen with other whole house fans. You simply cut a 14” diameter hole in the ceiling (or vertical wall), install the ceiling diffuser with a few screws, connect the duct to it and hang the fan assembly to the roof rafters in the attic. Then make the electrical connections, and the fan is installed! Experienced installers can routinely complete the installation in less than one hour, but an average handy person should be able to do the job in two to three hours.

9. Where should I install the Quiet Cool fans?

We recommend installing one in each bedroom for maximum comfort, and the remainder in common areas, such as at the top of a stairway, etc. Other ideal locations are laundry rooms, smoking rooms and kitchens.

10. What else is needed?

You will need standard wall switches or timer switches to turn them on. There are several types available. You can view the switch options when you checkout on the “Buy” page.

11. What is the warranty on the Quiet Cool fans?

Ten years on the parts, one year on labor, and the 30 day money back guarantee at time of purchase. All Quiet Cool fans are made in the USA!

12. What maintenance is required on the Quiet Cool fans

Absolutely none!. The motor has lifetime lubrication. There are no motorized doors or belts that could wear out over time.

16. What is the typical cost to install a whole house fan?

We have seen installations range in the neighborhood of $500-$1000 for 3 fans. Of course this depends on the installer, layout of the home, number of fans etc. Don't forget to check with your electric company to see if there is a rebate available. Since utility companies recognize the energy saving benefits of these fans, many offer a substantial rebate for installing whole house fans.

17. What are the roof vent requirements for a whole house fan?

Each Quiet Cool fan requires approximately 1.50 square feet of net free exhaust area (N.F.A). This number is derived by calculating 1 sq. ft. for every 1000 CFM. Each Quiet Cool fan generates 1500 CFM. Most homes that are constructed to building code standards should have sufficient N.F.A. for 3 or more Quiet Cool fan installations. In most cases there is no need to add additional roof vents. Check with a local contractor if you need additional consultation regarding your attic ventilation requirements.

18. How many fans do I need?

Generally you will install one fan per occupied bedroom or other rooms in need of cooling. The remaining fans are to be installed in a common area.

Why shouldn't I install just One Quiet Cool fan?

Simply stated, one fan will not generate a sufficient amount of CFM. You need much more CFM to properly cool and ventilate your home. We recommend that one Quiet Cool fan be installed for each 500 sq. ft. (in a one story home) of living space to generate a significant flow of cool fresh air. In order to be effective, a whole house fan’s CFM rating should be 2 to 3 times the square footage of the house. Most average size homes will require 3-4 fans. Installing the correct number of fans will help ensure that you obtain a "breeze" of cool fresh air. We sell the fans in different system configurations. See the "buy page" to determine the correct fan system based on the size of your home.

Example: Let's say your home is a 2000 sq. ft., two story home, with three bedrooms upstairs, you could install 3-4 Quiet Cool fan's (2000 sq ft. x 2 to 3 = 4000-6000 CFM) one in each bedroom, and one at the top of the stairs. This will allow the fans to work together to create a maximum flow of fresh air moving through your home. Of course each home design, attic access, and venting requirements are unique, so the installation, location, and the number of fans that you can install may vary. Consult a local contractor or electrician to conduct a physical inspection of your home if you need further consultation before installing.

Larger homes like the 2004 Sunset Magazine Idea House in Valencia, CA (over 4000 sq. ft), accommodated 6 Quiet Cool fan systems.

19. Why are the Quiet Cool whole house fans more expensive than other fans often sold in home improvement stores?

The Quiet Cool Whole-House fan system is more than a large fan motor in a box, attached to your attic floor. The Quiet Cool is a complete ventilation and cooling system that consist of insulated flexible ducting, ceiling grille, and fan unit with positive closing doors that avert cold air intrusion. There are no belts to replace, plastic fan blades or mechanical doors. The Quiet Cool is the quietest, most innovative whole-house fan system on the market!

Why spend money purchasing and installing a home improvement store type fan that is too loud to install in a bedroom, living room, etc. Other whole house fans sold on the market can move a large amount of air, but are not very accomodating or versatile, due to the noise they generate. Consider, whole house fans are designed to be used when the outside temperature is cooler, generally in the evening and morning hours. Quiet operation is one of the main benefits of the Quiet Cool Fan. The low noise level will enable you to run the fans just about anytime. You can have a conversation, sleep, watch television, or read a book without the noise of other fans. You can even close the bedroom doors for privacy with the fans running.

We encourage you to test the fans sold at home improvement stores or by competitors. We are confident that you will realize that nothing on the market can match the Quiet Cool System.

21. There seems to be several knock-off brands copying your design. Is there a difference?

Our motors have a built in thermal overload protector and also an over-current protector switch. They are made in the USA, not in China. They are a split capacitor motor, not a cheap split phase motor. They produce 1500 CFM, not the 750 CFM that other fans produce.

Compare the sones (noise rating) and our 10 year warranty to other models on the market before you buy!
(A sone is an internationally recognized unit of loudness. Sones are linear like inches. Doubling the sone number is the same as doubling the loudness. To get a idea of what 1 sone represents; 1 sone is equivalent to the sound of a quiet refrigerator, in a quiet kitchen)
