I presently work at home, which means that I spend a lot of time in my office (ya think?). Unfortunately, this room is not a good one for air conditioning (or heating) in the house. I can often get 8 or more degrees of temperature differential between the office and the space outside the office door.
Behind the rear wall of my office is a closet that faces a hallway. I was considering running a duct with a fan (something like this) across that closet, so as to exhaust air from my office into the hallway. I normally keep the door (which is at the front of the office) open, so air should flow from the front of the office to the back, out to a different part of the house.
Is this a good idea? Is there some big, obvious flaw that I'm missing? Other than the obvious issues of wiring it up properly, is there any control issue that I'm not seeing?
