This was a gift from Emerson Collie. He brought this fan to us and installed it in July. We love to have the windows open and enjoy fresh air during the spring and fall, and this fan is so powerful, it completely exchanges the air in the whole house about every two minutes.
How to install a whole house fan with a smart switch. I chose a 24" direct drive fan and am using a TP-link smart switch to turn the fan on and off. Also tried using some 2" acoustic foam glued into the corners to dampen noise. This worked well and did lower the noise level slightly. My testing shows the house will cool down 4 degrees after 2 hours of running the fan on low speed. (10 degrees cooler outside)
