    Use your slide calculator and check your indoor wet bulb, and that will tell you your proper superheat for your load and conditions.

    That can vary allot from 5 -15-20 depending on what temperatures are inside and outside.

    Hunting -throttling -open on a TEV can be due to air-temp-obstruction.

    Check airflow
    Check sub-cooling
    check Delta

    Re-read the question. The question was not "What is superheat"?

    The question was "what kind of superheat number is everyone looking for in residential ac units with fixed orifice"

    It was answered properly by RPonson and Therm76.

    Take care.

    Exactly what I said. On the slide rule you slide it over to the indoor wetbulb you have, and then look at the outdoor temp., and then it tells you what superheat you should have.
