I should go the window unit route.  I don't thnik Ronda would give m any
flak and I've got plenty of power. One windows is right above the
breaker panel in the garage, same outside wall.  It would be a cinch to
fish another circuit up there if it became necessary.

 After a year of "discussing" the issue I was allowed to add a window
 unit to my computer room.  Before I would have to set the upstairs
 air conditioner to 68 to keep the computer room comfortable, but the
 rest of the upstairs would get too cold for my wife (separate units
 for upstairs and downstairs).  Since getting the window unit we can
 set the main upstairs air conditioner to whatever makes her happy.
 After a couple of months with the window unit she made a remark that
 she wished she'd let me get the unit when we first moved in to the
 house.
