          What a Difference!
          If you don’t have an attic fan, buy it now and thank me later. Intall was a breeze and the thermostat is a must have. It was a pain running the cord for the controller through the wall but I got it done. We have a 1400sqft ranch that was built in 2017. Im glad we went with the 3.4W. Any less powerful and regret would have set in. After a month of testing, my AC usage has been cut in half! At this rate, it will pay for itself in 3-4 years.

            Fan is quiet yet moves enough air to ventilate the whole house and the control is awesome, set a temperature at night and it will maintain that temp and shut off automatically.
