    Re: Measuring Subcooling

    If its a mini split you don't measure the subcooling, you charge by weight using the formula and chart in the install instructions.
    Otherwise there is often another shrader inside the unit for measuring high side pressure.
    Mostly found in Oxfordshire, UK :)

    Alternatively, if it's a heatpump, run it in heating mode and you will get your liquid line port.

    But as MS says, best is to weigh it in.
