    In a nutshell, "you want to measure at the outlet of your condensor".

    You can if you'd like measure it at both. And one great way to indicate if flash gas is present.

    More important here is, do you first understand why subcooling takes place and why it's important??

    HI KC8939
    All condensers are designed to do 3 things.
    1.Desuperheat 2. Condense (from a gas to a liquid) and 3. Subcool the liquid. The purpose of subcooling is to "Insure that only liquid enters the metering device."
    If not all liquid(flashing of gas prior to the metering device) will cut down the unit capacity. I agree w/R12rules reply. Good Luck...
