The QUIETCOOL QC-1500 (U.S. Patent #7497774) is an innovative whole house fan that is not mounted to the ceiling but instead is suspended in the attic with straps from the roof rafters. It's connected to an attractive ceiling grill with a patented acoustical insulated flexible duct, thus eliminating all vibration, rattle and noise in the house. It is so quiet in operation that it can be installed in a bedroom or sleeping room without a sleeping person being able to hear it. With the bedroom door closed you can enjoy privacy and individual control.

This cleverly engineered system can be installed almost anywhere in a ceiling or vertical wall in less than 1/3 the time it takes to install a Typical whole house fan. It has a damper with insulated doors that prevents cold air intrusion in the wintertime.
