    User-7084153, that's a fantastic question and this forum is the perfect place to find answers. But you're going to have to provide more details. Where are you located? Describe your house and the present HVAC system--you reference a "second unit." What is the "first unit?" What are your goals with a new system?

    First of all, can you tell us your name?

    It sounds like you have a house with three levels -- basement, first floor, and second floor -- and you are planning to install two air-source heat pumps. If this is a typical installation, one unit will serve the basement and first floor, and the second unit will serve the second floor.

    Ideally, these heat pumps would be located near the center of the house, in a mechanical room. The heat pumps can be on any floor, as long as (a) the mechanical room is inside the home's conditioned space, and (b) there is plenty of room to run ductwork from the mechanical room to the rooms that need to be conditioned.
