PSC (permanent split capacitor) Motor
The Trident Pro Series is designed with a PSC (permanent split capacitor) motor. While not as quiet or energy efficient as the Stealth Pro Series models, the Trident series offers robust airflow and reliable production for a slightly lower price.
Innovated and Patented Design
The QuietCool Stealth Pro whole house fan features our patented, self-contained duct system that hangs in the attic to help neutralize any noise vibrations. The result is the ability to use the system at any time without sound disturbance.
R5 Insulated Damper System
The damper system features barometric pressurized gravity dampers that ensure no heating/cooling loss between the home and attic. Compare to traditional whole house fans that have old-style shutters with zero R-Value and it is not quite close.

Our Testimonials

Derrick and Jessica were great to work with. They helped us get thru the HOA approval process, and when the time came for the installation, it went VERY smoothly. We put in both an attic circulation fan and new roof vents to permit our attic to cool down in the summer. Derrick lined up the roofers who came and put the vents in at the same time Derrick was putting in the fan. In just a few hours, it was all done and works great. Derrick paid the roofers and just added that to his invoice. We could not be happier with the new system. If you want top quality and professional job, these are the folks to hire.

They quoted the work and came to install within the same week. They did a great clean and fast install. Would highly recommend them to anyone wanting a fan install. I wish I had had this installed earlier!

Whether you're reading Yelp or Google reviews, or those here on Facebook, you can believe all those 5 star reviews. The job was done in under two hours, they answered all my questions, reviewed the operation of the fan and two remotes, and left the area in which they were working perfectly clean. I talked to other QuietCool installers as well as those with a competitive fan, and chose to use House Fan Pros...it was a good decision.

Derek and Jessica did an awesome job installing a whole house fan in my Mission Hills apartment. They were prompt, honest, knew what they were doing, did quality work, and made every effort to minimize the mess. The end result is excellent, and I am very happy with the service they gave me. I would recommend them to anyone looking to install a whole house fan into their home.

Wonderful experience with Jessica and Derrick! I LOVE my whole house fan and they made the process so easy. Jessica was super responsive, answered all my questions, and gave me detailed instructions on how to operate my new system. Derrick was quick with the install and took extra care to clean up afterwards. I would highly recommend them to anyone looking for an efficient way to cool their house.

I love my new fan! Jessica and Derrick were on time, got the work done in a timely manner, cleaned up, and even helped us with an issue we were having with our solar system, which is above and beyond what they were hired to do. Just really nice people.
