    Replacing 20+ old Heil system

    I’m glad found this site lot of good information…….

    I'm having both Furnace & AC replaced(Furnace is Heil 90+ 125,000, AC 3.5 or 4 Ton Heil both are original equipment 20+ years old, AC is leaking and won’t hold charge for the summer). The house is a quad level, top floor is 3 bedrooms & 2 baths and the location of the furnace, level 2 is kitchen, living room & Dining room, level 3 is Den and bath, 4th level is basement, basement is the only level with door on the steps. Level 1 & 3 are feed from the same side of the trunk while levels 2 & 4 are feed from the other side of the trunk. T-stat is located on level 2. In current system, temp vary a lot between floors,
    would a 2stage with VS blower help evening the temps out?

    Other suggestions on trying to get better balance of temp though the house?

    Thanks

    Zone it.

    With the stairs open between the levels, a single zone single system won't heat or cool evenly.
    The heated air will always rise, and the cold air will always fall.

    Size it right. Too big means short run cycles. Having the 2 stage will help but oversized 2 stage is about like an expensive single stage. I have one.

    What kind of question should be asking about having it Zoned? I have not had anyone suggest to have it zoned yet. Are there more than one way to zone the house?

    Thanks

    There are several zoning systems/brands. And several methods.
    Interview your contractors. Then post there selections and zoning design ideas. Its easy to answer your questions then.
