why did they install the twin window fan and how did they did?
According to www.epinions.com, to install the fan you measure the window area and add the correct number of extender plates to the left side of the fan. The right side of the fan has a built-in extender plate that you adjust after you have inserted the fan into the window and properly closed the window onto the fan. Installation was a breeze; took about ten minutes. This type of fan can be used in double hung, slider, and casement windows which makes it quite versatile. The Holmes Twin Window Fan has a marvelous “Comfort Control Thermostat” feature that enables you to set the fan to turn on and off based on the room temperature. At night, this equates to the fan self-starting when the room gets warmer. This capability is a great selling point for why to buy this product. Sources: http://www.epinions.
