Whole house load calculator

Trying to educate myself as best I can on AC. I have had 2 estimates so far and one tells me I need a 3 ton system. The other told me my house is a 2 1/2 ton all day long. Although they must do a load calculation for permit.

Some of my duct is in poor condition and I believe is sized for a 2 ton AC, while the current AC is a 2 1/2 ton unit. I was directed to this load calculator and it seems I need a 2 ton unit but am not sure. So am I reading this right, that a 2 ton unit would be the right size?
