Mike, how much cooling do you need? How "hot" did it get in the summer? My Parents installed a 3 ton A/C unit in upstate NY which was fine for 2800 sq feet. I have 3300-3400 here in Houston and 7 tons of cooling with 2 separate A/C units.
A good professional A/C person will evaluate your insulation, cooling requirements, etc. I would get a few people too look.
In Texas, the price of electricity means the super-duper efficient units won't pay back enough in energy savings. California, with the much higher price of electricity, you will need to evaluate the operational costs vs. installed cost.

a 3 ton unit for over 3000sq' ain't gonna cut it. I don't care how you look at it. But then what do I know, I have never done any work outside of CA, SoCal for that matter.
