Glen, does your office have a floor register?

If so I have one of those floor register boosters you set over the register. It uses the temp difference between the vent and room to run a fan to draw more air thru the register while the central air is running to put more hot or cold air in the room.

Used it on my brothers room before putting in a window AC unit to keep the room cool enough for him without freezing the rest of the house. Because of his MS if it got above 70° for very long he would become paralyzed. Needless to say, it was not very comfortable for my Mother and I trying to keep the rest of the house cool enough to keep his room at 70. Besides it was pretty expensive in the summer time.

Saw it packed away in a dresser drawer the other day. You are welcome to it. Maybe it will help.
