    Both will finance, thanks for the help

    LOCALE?
    Age of home?

    Specs seem to hint that your 3,800+ square foot home is located in the North ( > 45' N Latitude).
    96,000 BTU/HR output might be sufficient for a 5,000+ square foot modern home.

    What do the ACCA Manuals J and S calculations indicate is a proper selection?

    It is in Minnesota, home is 1930 built. I'm trying to decide between a 96% efficiency Goodman 100,000 btu multi speed, 14 seer Furnace and a.c., or a 95% York 13 seer Furnace and ac

    I think the higher efficiency of the Goodman and higher seer would be the better choice, but I don't know which brand is better York or Goodman. Thanks for the help

    Best brand information-

    https://www.angieslist.com/articles/...vac-brands.htm

    What my biggest question would be, is did I really need 110,000 BTU/3 tons worth of equipment, and did I have the duct to support it?
    How did the contractor come to the conclusion that was the required size needed?
    Bigger equipment is not better.

    There is no return on investment on high efficiency equipment installed in a rental house. You don't pays the utilities. So ignore paying for a more efficient system.

    Why 100,000 BTU/HR for YOUR Building Thermal Envelope??

    __ Square footage?
    .......i.e. 1,800 sq feet per floor, 2-story

    __ Type of Windows __ ~ 80 years old original
    __________ or Perhaps 10 year old double or triple pane??

    __ Blower Door Test should be performed along with the recommended Sealing.

    Ability to rent a house depends on the Renter's TOTAL BUDGET.

    Most all renter are not influenced by the energy costs, this is way on the bottom of the list. I have rented many rent houses for 25 years and have never been asked to see the utility bills or asked what type of heat is used.

    Thanks for the advice, Im hoping to move back into the house once I find another job in Minnesota or I get transferred back to Minnesota. So I'd like to choose the better equipment for long term, house size is 3000 sqft, 2 story, no basement just built on a concrete slab.

    Don't focus on the "better" equipment. Or the brand.
    The nicest equipment money can buy will be a mess if it's sized, selected or installed wrong.
    Get it properly sized, and installed to spec.
