    Tell us what you already know about the proper charging of air conditioning systems and then we'll take it up from there...

    Building Physics Rule #1: Hot flows to cold.

    Building Physics Rule #2:
    Higher air pressure moves toward lower air pressure

    Building Physics Rule #3:
    Higher moisture concentration moves toward lower moisture concentration.

    when charging a unit and the temp is high you can always open the suction line and pour it in untill the temp drops

    or you could ask your instructor or jim wheeler
