Not with an AC unit. Oversized can be a big problem!
The first question I would find out is why your old 4 ton unit couldn't keep up, was it a ducting problem (under sized? no returns?) or a size (tonage) problem. Whoever is going to install this unit should do a through inspection on your duct system.
The seer rating really isn't that important, all it is, is the energy efficiency of the unit. You need to figure out how much energy you would save with a 14 seer over a 13 seer per year and figure out how long it will take to pay back that extra $1000 (ROI). If you can afford the 1000 up front and plan on staying in the house longer than the ROI then go for it.
The only other advice i can give you is get multiple quotes and check out different brands and compare the warrenty's

I'm amazed at how small and quiet these things have become, it has made an incredible difference in our house. Also put in an AC unit, which should be a welcomed addition. The only thing I really know about it is that they are f'n expensive and couldn't have come at a worse time.

Things can change over times when the last load calculation could have been done. Insulation getting poorer, windows getting older, etc.
