WHAT IS A WHOLE HOUSE FAN?

A whole house fan is a ventilation cooling system that uses less energy than a traditional air conditioner. This energy-efficient system works by pulling cool, outdoor air into your home and out your attic vents. This process enacts Thermal Mass Cooling, keeping your home cooler, longer.


HOW DO WHOLE HOUSE FANS WORK?

Since it is normally cooler in the evening and mornings, this would be the best time to turn on a whole house fan. Homeowners simply have to open a few windows and the whole house fan will cool and ventilate the entire home. Whole house fans can exchange the entire air in a home every 3-4 minutes or 15-20 time per hour. When running the system for several hours, all the hot air will be pulled out of the mass in the home. This process is called Thermal Mass Cooling. The hot air is pulled out and then vented through the attic. This allows the home to stay cooler the next day because the entirety of the home was ridden from heat. The home will feel significantly fresher because of this.


Anytime it is cooler outside than the inside of a home, the QuietCool whole house fan system will work effectively. In the summer, this normally happens in the late afternoon to early evening and through to the next morning.


WHAT HAPPENS When whole house fans are turned on, the fans will pull the cooler outdoor air into your home, through your windows, across your living space, into the attic, and out the attic vents, replacing the hot, stale air. This helps cool the home and attic by up to 30 degrees Fahrenheit or more. When using a QuietCool whole house fan, we 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. Assuming this is the case, it is where you would want to start cooling. As it gets later in the evening, and even cooler outside, we recommend opening more windows in other rooms of your home. Then, when it is time to sleep, 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. Remember when using a QuietCool system to be sure not to open too many windows or open any single window too wide. 3-6’’ and just a few windows will suffice to make your home a fresh-aired paradise.


INSTANT BREEZE

The cool breeze begins when a window or two is opened and the QuietCool fan is turned on. The cooler outside air will immediately begin to create a breeze inside the home making the homeowner feel up to 10 degrees cooler, and sometimes more, instantly.

This breeze will be carried through your home to each QuietCool whole house fan that is on and in use; thus beginning the cooling process. At the same time, the cooler outdoor air will be brought into the attic and pushed through the attic vents causing the hot stale air in the attic to be exhausted. Exhausting the hot air inside your attic will allow your home to stay cooler throughout the day.

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 as we recommended, the homeowner can enjoy the breeze and your privacy with your door closed.

Note: When using the QuietCool system, be sure to not open too many windows or open any windows too wide, as this will lessen the cooling breeze that is felt. There is a “sweet spot” when window opening(s) throughout the home are “just right” to cause a nice active breeze to be felt at each open window.


THERMAL MASS COOLING

QuietCool should be used anytime the outside air temperature is lower than the inside temperature. This is key for the principle of Thermal Mass Cooling to work.


REALITY TALK

What do many people do when they come home after work and it is really hot outside but cool outside? They open their windows instead of turning on their A/C so they can draw in that cool air. These open windows create a cross breeze and cool the home through thermal mass cooling.


TECH TALK

The “passive” cross breeze described above becomes an “active” breeze for QuietCool homeowners and this is the key to thermal mass cooling. Passive breezes within a home will eventually cool the ambient air to a comfortable level but will not move enough air to cool the mass within the home.

When correctly sized, a QuietCool system will fully exchange the entire air volume of a home 15-20 times per hour, or about one full air exchange every 3 to 4 minutes. The “active” breeze is how QuietCool thrives.

Mass “cooling” results because the QuietCool system is removing stale, hot air and replacing it with fresh cool air. All of this is occurring at a high rate of speed and volume, 15-20 times per hour, which is why it works so much better than a simple cracked window.

Therefore, instead of recycling hot, stale ambient air through a closed-loop air conditioning system, the QuietCool system is exchanging hot, stale ambient air with fresh, cool outside air, through an open-loop whole house ventilation system… and at a fraction of the cost of running an air conditioner.


NET EFFECT OF COOLED MASS

A “cool mass” home does not reheat as much or as quickly as a “hot mass” home. Within a day or two of installing a QuietCool system, homeowners often come home after work and their house is still cool from the night before. The reason the home remained cool was that the mass of the home had been cooled by a QuietCool system and thus did not reheat as rapidly as it typically would. QuietCool is truly a revolutionary product that allows people to save money by turning their A/C off and turning their QuietCool system on!


MORE BENEFITS

The whole house fan is designed to complete 15 - 22 air exchanges per hour, while moving 5 times more air than AC.


Quality Parts - QuietCool’s fans are powered by a PSC motor which is one of the best on the market today.


QuietCool simultaneously cools, cleans and replaces the air in your house all while giving you a return on investment (ROI) typically within 12 months


INSURANCE & WARRANTY


Being fully insured, our technicians work under QuietCool's 15 year warranty. If there is a part that gives out, QuietCool supplies; you only have to pay for labor.


PRICES

One of the difficult things to figure out is the median price for fan + labor. So I've personally went out of my way to figure out what the competition will charge. For a 2400 sq. ft. home, you will find some guys will charge up to $1750 for the Trident Pro 4.8. Some guys will give you this price, then say you get a rebate of $100 if you "book now before the week is up!", which personally to me, is a scarcity tactic to get you booked ASAP. Keep in mind that anything above $1600 would be considered pricey for that particular model.
