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

    Is that your mom!: Where you from you sound like your french. If you want the correct answer You will have to tell me why. This is not a DIY hot line where you ask a question and get a answer. We as professional will educate you to certain degree and help you make a informative choice on equipment or services and not help you DO IT YOURSELF! We have to keep it a secret so the british don`t steal our technology

    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.
