Would a window ac unit do as good a job of dehumidifying the basement
as the dehumidifier while cooling the room as well?



Probably not. An AC unit will be trying to cool the air, if the room is cool
it will not run.
Have you considered that running two AC units and possibly a third, and/or a
dehumidifier, it may be cheaper in the long to put in central AC?
