    I'll be a contrarian.

    What size system are you replacing?

    What size living space?

    I think a 2 stage condenser is overkill and unnecessary for what seems an obvious small living space.

    Assuming you have an AHRI matched system, I would match CFMs/ton to your comfort and conditions. Most installers would set to 400 CFMs/ton which would be correct for most installs.

    Use this as a template. Other brands OK like Carrier/Bryant and AmStd.

    Assuming you have leverage between electric versus nat gas rates and temp balance point is lower than 40 degree,that setting defeats the purpose of a DF package system.

    Correct sizing and increased efficiency should save you in operation costs both furnace and AC.

    MRBD

    Insist on a load calc both heating and cooling.

    I would bet that a 60 K furnace and 3 ton AC condenser is the correct size.

    If furnace goes in crawl space, I would consider a 60 K XV95...

    You need to know how to adjust your switchover outside temperature. I would start with 32 degrees and adjust accordingly based on your comfort level and operation of the heat pump.

    The Carrier furnace is 30% larger which raises an issue.
