    That line is sometimes called "the HOT gas line". It's HOT.

    The "discharge" line coming out of the compressor is "very hot", but
    the "liquid line" coming out of the condensing unit is just warm. (the smaller of two lines.)

    The discharge line is usually not very accessible from the outside so I believe it is the terminology that is getting confused.

    A significantly hot liquid line may indicate dirty coils.

    If the system is stabilized with interior temps around 70F, has been operating for some time, and exterior ambient temps are below 95F, then the liquid line should not be much warmer than your own hand. The suction line should be approximately beer can cold under same conditions.

    This is of course a generalization and other specific factors and checks must be performed.
