I'm afraid you've come to the wrong place with your question.
There are too many other variables to consider to be able to come up with a good answer.
I would suggest you get several contractors in to quote you on this and ask for a detailed load calculation.
They will also determine if your existing blower and ductwork can handle the required cooling capacity.

yes, get a few quotes. my house is similar to yours in upstate ny and i have a 2.5 or 3 ton unit. it should take a person about 30 minutes to determine the size..... they need to measure the home and look at some of the duct work.
