Sounds like a good system. It may be beneficial for you to do other upgrades first like better windows, better insulation, sealing the house up...ect....ect....You may find that you don't need a 4 ton system for your house once you do those upgrades......Also one system to keep a 3 stories conditioned is going to be a big task in itself.
