It is all a balancing act. A major issue is removal of humidity.
A too large unit will not only cost you more to run but will run less so will not remove the humidity as well. The result is you will have a home that is too cold and too damp.
You say you have one section that does not cool well. That is a distribution problem. Remember your ducts pass through your HOT attic. You should check that first of all the vent is fully open. You should also check that your ducts are properly insulated and properly connected in your attic. Have you changed the filter?
