The Problem
Our Homes Are Hotter Inside Than Out
When we leave our homes for the day, the air heats up and stagnates. This hot air rises and expands, making the home uncomfortable and preventing cooler air from entering.
During hotter days, in-home temperatures can reach 100 plus degrees. Hot expanding air also accounts for the difficulty in using small fans to blow cool air into the home as these fans lack the volume of air movement needed to rid the home of heat.
Some homes have hot zones or specific areas where there is inadequate air circulation for reasons such as not having windows, a window that faces the afternoon sun, having a poorly constructed ceiling or the lack of a cross-breeze.
The Solution
Stay Cool, Stay Green
A Whole House Fan is the only fan powerful enough to cool the home’s living space and the attic. It does this by exhausting the hot air out of the home and drawing cooler air through the living space.
Since installing the Whole House Fan and Solar Guard Insulation in August of 2009, I haven’t had to use the A/C once!”–Peter, Ewa Beach, Oahu
I’ve told a dozen of my friends about the Whole House Fan, it’s the best improvement we’ve made to our home.” –Shaina E, Kailua,
Whole house fans help cool your home by pulling cool air through the house and exhausting warm air out of the house. Typically, these very large fans are installed by professionals in the attic of the home.” –The Environmental Protection Agency (EPA), Green Homes
The Whole House Fan is also remarkably Energy Efficient. With energy consumption starting at 47 watts, and HECO rates of 35 cents per KWH, Whole House Fan use pennies of energy per hour.Verified and Proven

Save up to 90% off your A/C Bill
Whole house fans are the most energy efficient cooling systems available. Many Hawaii homeowners are able to minimize, or eliminate A/C usage during all but the hottest days. This allows homeowners to recapture their investment quicker than many other energy efficiency products.
“Since I installed my Whole House Fan system in 2011, it’s been all I’ve used to cool my home and saved me money off my electrical bills. I saved more when it came time to put in Solar [photo voltaic] by installing fewer panels. I tell everyone about it, it’s amazing how it sucks the hot air right out of my home!” –Pam Sato, Mililani
Patented Whole House Fan System
QuietCool is a patented whole house fan system that is suspended in the attic and ducted down to your ceiling to allow quiet operation. This unique design has changed the industry. Look no further than QuietCool; the quietest and most energy efficient whole house fans on the market.
Cool your Entire Home
A QuietCool whole house fan system exchanges the volume of air inside your home 15-20 times per hour. This continuous circulation of air reduces heat build up, cooling the home to the temperature of the ambient outside air. In warmer homes the system can cool the inside living space by 20 degrees or more and the attic by 30 degrees or greater.
Smell be Gone
With a Whole House Fan system you can exhaust your home of cooking, pet and other odors. –Enjoy a healthier, odor free environment.
Whole House Fan Sound Level
QuietCool whole house fans are the quietest systems available with sound levels that vary from 43dB (decibels) to 57dB depending on the size of the system. For comparison, this is similar to a normal oscillating fan on low or high. While these sound levels are considered very quiet, not all systems are appropriate for installation in all areas. (You wouldn’t want to put a larger unit in a bedroom).
Also, since many Hawaii homes lack insulation, it’s important to talk with a consultant who can help you to determine the correct system for your home.
Made in America
QuietCool systems are manufactured in southern California, USA in QC Manufacturing’s 43,000 square foot plant.

How do Whole House Fans Work?
Installed in the attic of the home, whole house fans draw hot air out of the living space and push trapped heat out of the attic. This action pulls cooler outdoor air into your home, through your windows, across your living space, cooling your home.
When using a whole house fan, we often recommend starting by cooling the area which will be most occupied. For example, in most family situations, the early evening is spent in the kitchen and family room area. Usually this is where you would want to start cooling.
The cooling begins when the QuietCool fan is turned on. As the cooler outdoor air is brought into the home and travels through to the ceiling grill this will force the hot stale air out of the attic as well. Preventing attic heat from building up will greatly reduce the time it takes in the evening for the home to cool down.
As it gets later in the evening, and even cooler outside, we recommend opening more windows in other rooms of your home. Then at bedtime, close all the windows in the home except those in the bedrooms that are occupied. This will provide each room with a cool breeze as long as needed. If a QuietCool is installed in each bedroom, the homeowner can enjoy the breeze and privacy with your door closed.
Note: When using the QuietCool system, you may want to not open too many windows or open any windows too wide, as this will lessen the cooling breeze that is felt.
With its warm sunshine and cool trade winds, Hawaii’s beautiful climate is moderated by the temperature of the surrounding ocean. In downtown Honolulu the range between the coldest and warmest months averages only a 6° F difference. In the leeward areas, temperatures in the low 90’s may be reached on several days during the year, but temperatures higher than these are unusual. In windward areas, elevated areas and neighbor islands air temperatures are even more comfortable.
A Whole House Fan can take advantage of a home’s PV solar system for power. As the main purpose of the Whole House Fan is to provide on-demand cooling, having the fan grid-tied allows the homeowner to use it in the evenings and night when the sun has gone to bed.
CFM (cubic feet per minute) is the measure of air that is moved by a fan. Fans with a higher CFM can cool an area more effectively. The Whole House Fan is sized to remove the air volume of the room to be cooled in three minutes or less. While a smaller fan can move 600-1200 CFM, a Whole House Fan will move from 1500 to over 10,000 CFM. Summary: A Solar Attic Fan is great as an attic vent, but the energy efficient Whole House Fan has a greater impact on home cooling.
