    So I can read most model numbers, but the Ruud/Rheem numbers continue to baffle me. What is a Rheem model RBHA-14J05NFAA?
    And on a 52 degree day, is a 10 differential with 80 degrees at the closest register in heat pump mode satisfactory?
    Thanks, JLMathis

    what is 10 differential ?
    Are you talking temp rise ?
    If so how are you measuring it, and where from ?
    On a 52* day you should do much better then 80* at the closest suppy.
    Even the longest one should be much higher then that.
    Check your filter and check for air leaks.
    If you try to fail, and succeed.
    Which have you done ?

    That is a 1 1/2 or 2 ton with 5KW electric heat. 10º seems pretty the heat pump condenser running?

    You need to measure temp rise right over the unit, not at registers. On a 52 degree day with just the heat pump, you should be around 30 degree increase. 5kw isn't much heat so air won't be too much warmer with backup on.
