Our client in Castro Valley, CA reached out to us wanting to install a QuietCool whole house fan in their attic. After our technician’s inspection, he determined their attic was currently in good condition and would benefit from a new house fan. Our team installed a QuietCool whole house fan in the attic. This new ventilation system will replace all of the hot air. A QuietCool will save you 50-90% on your A.C. related costs.  In addition to this, our client’s home will feel much more comfortable during the upcoming summer season. The home is now energy efficient and up to code. We hope our client is enjoying their new house fan.
