Whole house fans have one traditional and cumbersome drawback, they have the propensity to get loud and get loud frequently. This incessant and increasingly loud noise level exists in a normal whole house fan because they are working with metal blades and cheap motors that do not bend with the air but fight against it.
These metal blades can also hit against the surrounding metal framing. Companies claim to have special material for their fan blades when in reality it is usually just clunky and normal metal. Meanwhile, Quiet Cool uses bendable aluminum that bends with the air instead of fighting against it, hence, completely quieting the normal propellor like sound.
Most whole house fans do not have a system to lessen the noise they creat. QuietCool includes a barometric pressurized damper system above the grille that seals at an R5 value that prevents minimal heat and air transfer back into the home. This not only improves the airflow in a significant way but reduces noise. It does this because air being rushed back into the home creates unnecessary noise. Taking that air away and funneling it completely out of the house makes for a a more streamlined system, production and noise-wise.
Traditional whole house fans also usually solely include the fan attached straight above your home, into the ceiling. This placement may be acoustically pleasing for a small band but not something you would want for a cooling system that you hope to forget is even there. Quiet Cool fans are placed in the attic, lessening the sound to an even greater extent. The difference is one is hidden away while the other is placed in a prominent part of the home. Other companies are also not as strategic about their placement like Quiet Cool is.
Finally and most importantly, QuietCool is the patent holder for ducted whole house fans, otherwise known as advanced whole house fans. QuietCool whole house fans suspend the motor head 3 to 6 feet away from the ceiling grille with a lined duct that dampens the sound level.
This allows the air to travel cleanly and quietly out of the house instead of being pushed into the attic and allowing the air to then do what it pleases. Quiet Cool’s sole ability to siphon air into and out of the house is the main reason your whole house fan is so loud and Quiet Cool’s are not. So next time you are questioning why your whole house fan is being so noisy, you should really be asking, why did we not buy a Quiet Cool fan?
