How Do I tell What QuietCool System I Need?
To determine what system you need we simply use a ratio of 2, 2.5 and 3 CFM for every 1 square foot of your home. This will give you a basic, advanced and superior system, respectively. We recommend closer to 3 CFM but no less than 2 CFM for the QuietCool whole house fan system to work at it’s full potential.
