    Here you go. Do your BTU calculations first then you will have a range to work with.

    The calculation came out to 5 ton system, I feed to a 20x21 duct to the entire home.

    I think something might be wrong with your calculations.

    Stuffing 5 ton/60,000 BTU's into a 20X21 inch duct sounds a bit to small to me but I did not do the calculations.

    I would check over you math to be sure. I like a quiet system.

    Of course it is a split system with inline controls each for half the home
