The Quiet Cool Story

February 15, 2018



The QuietCool story is the quintessential American
success story, actually invented in a garage!
One day, back in 1999, our founder and inventor —
an electrical contractor by trade — was installing a
traditional whole house fan into a customer’s home
when the customer exclaimed, “I wish someone
would invent a quiet whole house fan!”
And just like every great American invention that
begins in a garage, our founder tinkered and
tweaked his prototype QuietCool fan until he had a
workable, saleable product.
The first QC-1500 came to market in 2003, and the
rest is history. In March 2009, QC Manufacturing
was awarded U.S. Patent #7497774 for the QuietCool
whole house fan system and we’ve never looked
Today, QuietCool is manufactured and assembled
in our 50,000 square foot plant in beautiful
Temecula, California.



QuietCool is the revolutionary whole house fan
and ventilation product that has taken America
by storm. QuietCool users across America
experience significant savings when they turn
their air conditioners OFF and turn their QuietCool

systems ON.
Whole house fans are not new! They have been
around since the 1950’s, and they do exactly what
they claim to do; move a lot of air! So much air
that we move up to 7 times more air than an HVAC
system. Whole house fans were first used as an
inexpensive way to ventilate a home, cool it down,

and save money. Instead of turning on the air
conditioning unit - which uses a lot of electricity,
which costs a lot of money - whole house fans were

designed as an alternative to A/C.
The problem was that the traditional, old fashioned
whole house fan sounded like a helicopter in the
attic and, as a result, people would turn it on for
just a few minutes at a time. And whole house fans
need to run for long periods of time in order to do
their job properly. We’ll talk more about that in a
moment, but understand this; no matter how well
old fashioned whole house fans worked, nobody
liked them because they were so loud!
Then, along came QuietCool! We simply re-invented
the mousetrap... made it better, quieter, and more
energy efficient!
QuietCool is the patented whole house fan and
ventilation system that is whisper-quiet compared
to the traditional, old fashioned system. And
because it’s quiet, people will let it run for hours
and hours at a time, allowing the system to do its



What do many people do when they come home
after work and it’s really hot inside their home?
Instead of turning on their A/C, many people open
up their windows and allow a nice cross breeze to
enter their home, which not only feels good, but
also cools the home down.
The “passive” cross breeze described above
becomes an “active” breeze for QuietCool
homeowners, and this is the key to thermal mass
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 for any size home, a QuietCool
system will fully exchange the entire air volume of
a home 15-22 times per hour, or about one full air
exchange every 3 to 4 minutes
The “active” breeze that is created by a QuietCool
system is how QuietCool works. “Thermal mass
cooling” results because the QuietCool system is
removing stale hot air and replacing it with fresh

cool air; all this occurring at a high rate of speed
and volume, 15-22 times per hour.
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... and at a
fraction of the cost of running an air conditioner.
