    Alright, see if anyone can give me any suggestions. i've been a commercial installer/supervisor most of my career, i have done only a couple of years of residential. I know just enough to get into trouble. i've got a house to size up, and here it is. North Idaho, 2400 sq. foot main floor, with a 600 sq. foot bonus room, 2400 sq. foot unfinished basement.
    they want a heat pump with electric backup. so i came up with 5 tons for the main floor and bonus room. basement, 3 ton heat pump with 4 ton blower, the owner says he is using his wood stove in the winter that is installed in the basement.
    i have purchased the "manual d", but it has not arrived yet, and i do have my own "scientific" methods of common sizing that is used up here.
    any and all comments or suggestions are welcome. Thank You

    Mike

    Could always check out that red tab on the top of the page... probably the best way (aside from manual J).
