  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.

    We purchased and installed the QA-Deluxe 5500 fan just over a month ago in our 2800-square-foot, two story home.  Shipping was fast, as it arrived the next business day. We installed the fan ourselves. The damper box required assembly and took about 30 minutes.  We purchased the wired remote with time, speed, and temperature control. I used a stud locator to find a suitable wall location  for the remote.  Since we were going up in the attic, it was pretty easy to drill a hole and fish a wire to an electrical box switch box for the remote control. It took about 30 minutes to install the wired remote.  The rest of the installation took about 90 minutes, with most of the effort going into cutting the damper opening.   We have an open concept home with vaulted ceilings, so the sound of the motor carries.  We bought about 100 sq ft of rockwool insulation and placed it in the attic around the area where the fan motor and damper were installed on top of the existing fiber glass insulation.  That helped reduce the fan motor noise.  The remote control is not that responsive.  There is about a 1-2 second lag between the time you push one of the buttons and the update of the digital display.   Overall, the system works well and is not that difficult to install if you are handy.
