    5-ton

    is alot unless it is a very big house, or it has a ton of SW exposed glass.
    Also if the house is in a woods at the bottom of a hill you will get a downflo from the hill, especially as soon as the sun starts to go down. Actually any shade at all can make a big difference when calculating cooling loads.
    I often err on the low side rather than the high side, you can reason with people if their place raises a few degrees, about eff. of the system and the better dehumidification on the "moderate" days. If you size strictly for the hottest days you will have a refrigerator cool on the moderate days.
