Nice looking whole house fan kit right out of the box and everything was going great on the install until we found the wireless smart control would only run the fan at one speed. After diagnosis with the company it was determined that the control would need to be replaced. The sad part is the control came out of a sealed box that said quality inspected....
I sent all the help home and called Quiet Cool when they opened on Monday and was assured that a new part would be in my hands by Friday so I enlisted all my help to be onsite this weekend. The control still is not here and will not be until Tuesday so I now I need to wait another week to install the unit.
Extremely disappointing for the cost of the kit and I actually worry now about the reliability of the control once it lives in an attic with huge temp swings.
