    I just purchased a 100 year old home here in Louisville Kentucky. The furnace was shot. There was no duct work for the second floor. I have removed the drop ceilings and have room to run new duct work for the second floor.
    I want to install a new heating and air system in the house. I intend to be here for a few years maybe more.
    I have gotten mixed information on what components to use.
    Some say use a spit system, a heat pump with a gas furnace others say heat pump only and still others say gas funace and central air unit.
    On the gas funace end I can get a pretty good deal on American Standards top of the line furnace the Freedom 90 Comfort R from a friend of mine that does commercial work.
    Just to get a second opinion I had a contractor from my area come over and give me a bid. He said that particular furnace would be a waste in my house, he recomended a Rheem Classic 90 Plus. He recomended a 14 sear air conditioner were the other recomended a 14 sear heat pump.
    The home is a 1500 sq ft two story shoot gun house that I am insulating and replacing the windows with two pane.
    I really am at a lose here. Our local gas and electric company just raised gas rates by 64% and I need to get this system in before it gets much colder. I want to do it right, but don't want to waste my money on the best if it won't make a difference.
    Please help.

    If you can get a deal on the American Standard then go for it. The other guy said that it would be a waste because he wants commision. The company I work for sells american standard equipment, and in the 6 or so years that they have been installing it they have only had one warranty service call. Plus, they come with a pretty good warranty

    For starters,
    Gas Rate ......$ _.__ MCF
    Electric Rate .$0.___ / kW
    Did you check WINTER rate specifically for Heat Pump?

    Help yourself by helping others
    obtain a more specific 'reference point'.

    I don't know what a shoot gun house is.

    1,500 S.F. and Louisville are good info.
    800 [ ? ] S.F. Down stairs
    ?___ S.F. Glass North ___ S.F. Glass South
    ?___ S.F. Glass East ___ S.F. Glass West

    700 [ ? ] S.F Up...stairs
    ?___ S.F. Glass North ___ S.F. Glass South
    ?___ S.F. Glass East ___ S.F. Glass West

    Ceiling_ R-value 19, 30 or 38 ?
    Walls __ R-value 11, 13 or 19 ?

    Infiltration ___ 100-year old house
    Has any testing been done to determine leakage?

    Windows S.H.G.C. ____ U-value ____

    W.A.G.
    ~50,000 BTUH Heating
    ~25,000 BTUh Cooling

    3 MIGHT be appropriate .. but
    Who knows exactly??

    TRANE Heat Pump model ( or equal)
    4TWX 6036 /4TEE3F040 with 10 or 15 kW electric strip

    .... BTUh for Heat Pump & Coefficient of Performance
    O.A.T.
    17'F _ 22,200 BTUh C.O.P. 2.96
    35'F _ 25,920 BTUh C.O.P. 3.28
    47'F _ 33,200 BTUh C.O.P. 4.06
