The product Build Time you see represented on this site is only a typical number of days the manufacturer states it needs to build the product(s) when ordered. Build times are based on business days (excludes weekends & holidays).
The build time does not include the time it will take to ship the order to you (the customer). If an order has multiple items and comes from multiple warehouses, you may receive part of your order on one day, and then receive the remaining part(s) of your order at a later date.

The QuietCool "classic" patented line of whole house cooling and ventilation fans have revolutionized the residential cooling industry. Open the window and let a QuietCool system exchange your stale hot air for cool air 15-20 times per hour and reduce your a/c related energy costs by 50-90% and see your electricity bills plunge!
Using an innovative (and patented) self-contained acoustical ducted system to separate the fan motor-head from the ceiling intake grill, our ducted fans sound "whisper quiet" within the home, making the loud, old-fashioned attic fan obsolete. Our whole house fans also include an airtight gravity damper system that seals shut when the fan is turned off, thus preventing air back flow into the house, while providing an above-industry standard R-5 insulation value.
The original "classic" line of whole house fans is perfect for the budget conscious consumer and pay for themselves on average within 1.3 - 1.8 years; the fastest payback period for any "green energy" appliance on the market today, all backed by an industry-leading 10 year warranty.
