correct amount of A/C tonnage for a 2,380 square foot home

Our contractor wants to put in a 16 SEER 5 Ton TRANE unit. The house is new construction with 2X6 exterior walls, facing NW. sitting on a hill with very little shade. R-19 walls and R-30 ceiling with 10 foot ceilings with the exception of one or 2 rooms that have a coffer ceiling going to 12ft. Window amounts are average with double pane aluminum vinyl wrapped. Can we get a 4Ton unit since we normally keep the house at between 77 and 78 degrees in the summer in S.E. Texas. I know about a manual J study but nothing more. I have lived in some places where the air never dried out and am as concerned about over-kill as I am about over working the A/C
