    Ok you lost me on the conversion already, 17 degrees F? over the coil? Which is 9.44 C correct?

    20 KW element that rarely comes on, Thou two stages come on every defrost cycle..

    So how should this system run? All the time slow? Or once an hour? I have heard many answers to this...

    2100 CFM is what it is rated at I believe.

    The blower is capable of 2100CFM, but its heat rating is at 1950, and lower.

    Once your down around 17F(-8C) It should have long run times. And I wouldn't expect it to have more then 2 cycles per hour at most.
    It should be running in second stage(high stage for the heat pump).

    Do you know what your outdoor design temp is?

    I think 17F rise is 8.5C, but I could be wrong on that one.

    How many times must one fix something before it is fixed?

    If I'm getting the proper rise with the single stage is that not good? I was told that in these parts it should run single stage 80% of the time, no thats from the guy that really has help me so far, he is 4 hours away.



    Not sure what you mean by Outdoor design temp..

    Outdoor design temp. Is the temp which your area uses for sizing heating equipment.

    The temp rise I gave was for it to be in high stage.
    In low stage, it would be 15F at 1200 CFM.

    Your blower shouldn't be running at high spped in first stage heat pump.

    I'm wondering if your strips aren't coming on that you don't know.
    Perhaps due to a mis wire that the stat isn't indicating it.

    I have a thermometer that reads temp at vents and I watch it as much as my TV, If the strips come on you can tell in 5 seconds.. I think it may just be the fan, and I will be having the CFM tested Monday..

    Update

    Machine was not wired properly, " Hot Heat Pump" option not turned on, Jumper option, and Poor duct work.. Heat pump is running fine and tin is being done this week, don't even ask what the static pressure was...
    Thanks for your help.....

    Had to get a guy in from 3 hours away...
