    Help with rating old HP

    Last January I replaced a 23 year old Ruud heat pump and air handler. I can't find out what SEER or HSPF the unit was. Could someone please provide that info. It was purchased new when I built my home in 1989. It seems as though it was a mid-range model.
    This is the info on the old contract I dug out. The unit is no longer around for me to get any other numbers off of.

    3 ton Ruud outdoor unit UPFA-036JAS
    indoor handler UHQA-1215-JXX with 15 KW electric heat.

    Worked flawlessly until the compressor gave out last year

    Thanks

    For midrange equipment, maybe 11-12 SEER and maybe 7.5-7.8 HSPF. But someone that knows rheem/rudd can give a better answer.

    So you already repalced the system, but wanted to know how much energy the new unit should have saved?

    I would be surprised if it was that high. This was in 1989.
    Yes, I just wanted to know the numbers on the old unit.

    Thanks for 8.65 SEER info. Any info on the HSPF heat rating for that unit?

    Thanks again

    Well, 8.65 is a COP of 2.5 and heat pumps are less effcient in cooling that heating because of defrost requirements and larger temperature difference ofmr indoor to outdoors. HSPF is maybe 6.5. Defnitely under 7.

    Looks like i got beat above. Hey, good estimate on my part.
