    Hmm sub cooling and super heat

    How do you check sub cooling and super heat? Dumb question I know but I am new in the field. I am just a parts runner right now. I am starting school next month.

    If you don't know, then don't do. If you don't know and still do, then be prepared to pay someone else a lot to undo what you did and then do it right.

    If you do know, then do. But do it right. Otherwise, you may not be doing it long.

    The questions you are asking make it sound like you are still in school and getting ready to take a test.
    Are you?

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

    Kind of makes you wander what they are teaching in these schools... Don't know how to get a superheat or subcool reading... It's not really hard to do... if you are not in school and are in the field... Why not just ask a co-worker... If you are fresh out of school they will not think you are dumb for asking... Better to go on a call well informed than ill informed...

    Funny how some of these "members" jump at the chance to insult. I believe the gentleman said he was about to start school. You can get a charging chart from your local parts house that gives you step-by-step instructions for super heat and sub-cooling, providing you have the instruments to abtain the pressures and temps required.Just make sure you practice on your own system, not your mother-in-laws.

    Come on guy's, have a heart!

    With a set of guages and a temperature probe. The difference between the refrigerant temp and the line temp is your super and sub.

    If more government is the answer, then it's a really stupid question.

    Well you know captain... After being locked in attics all day long... We have to find a way to vent off some steam... :P Just skimmed over what he posted... Since he is about to start school... They should teach him how to do it...

    Very simple.

    SH is how much liquid is feeding the evaporator in relation to how fast it is being boiled off. Soo you know suction pressure ( evaporating temperature ). Now subtract from tubing temp and you got SH.

    SC measures difference liquid line temperature and condensing saturation temperature. This time use head pressure.

    If you look, you'll see he edited his post after I asked him if he was in school.
    He just asked how to check at first, he added the part about school after I asked.

    You don't need to vent steam on posters.
    Merry Christmas
