    I had a company come out and give me a bid on a furnace. A Goodman GMV80704BX. I was looking on the net for info the pdf of the manual. Like the ones on the Goodman site. I can not find any, is this a good number. Thanks, jmb

    That is a two stage, variable speed, 80% efficient 70,000 Btu furnace with a 4 ton blower capacity. It is 17.5" wide and is set up for no NOx to meet California codes.

    G = Goodman
    M = Multi-position
    V = Variable speed blower
    8 = 80% efficient
    070 = 70,000 Btu input
    B = 17.5" cabinet width
    X = NOx

    Thanks

    Ok so that is a good number. Must be a older one, not brand new like on Goodmans web site. Thanks

    OH yea one other thing

    I was going to go with a 4 inch media filter base. What is the recommend return size for this furnace. I was going to put in a 18 x 30. I think that is more then enough.
