I am thinking about buying a Panasonic WhisperWall fan, http://www.amazon.com/Panasonic-FV-...ounted/dp/B000MNIB9C/ref=cm_cr_pr_product_top . I am not sure where and how to install it. Should I install it on one end of the room or the middle. In the middle, there would be an existing electrical box, but no easy access for operating a switch since there is furniture there. I guess it comes down to "how to run an electrical extension cables and boxes several stud bays over without ruining the drywall?"
