  1. D McKenzie

    I purchased the Centric Whole House fan. I absolutely love it! I live in Sun City, AZ yesterday was 107 degrees. I wanted a way to cool down the house at night. I turned on the fan at 10pm last night, opening the bedroom windows and the front door. It was 84 degrees. I kept the ceiling fans on. The fan created a cooling breeze, the temperature was 72 degrees this morning.
    I plan on using this fan all year round. In the winter I will turn it on at midday to bring in the warm air to heat the house.

    The fan is very quiet, I had it installed in the living room, which was closest to the access and met the height requirement. My contractor took about 3 hours to install. The most time spent was to get power. I had many questions and had help from both Dave and Mike. Very easy to deal with, a wealth of information. I wanted to support a small business. A selling point to me, was that the fan is made in Germany and has a 15 warranty.

    This doesn’t take the place of AC, but allows a very cool but not cold sleeping environment.

    Very happy with this system. Purchased for my 2600 sq ft two story home. I also got the two speed remote with temperature control. I set it at 75 degrees before going to bed and it automaticaly turns the fan on and off through the night.
