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

    (maybe)
    • Electricity makes refrigeration happen.
    • Refrigeration makes the HVAC psychrometric process happen.
    • HVAC pyschrometrics is what makes indoor human comfort happen...IF the ducts AND the building envelope cooperate.


    A building is NOT beautiful unless it is also comfortable.

    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

    Charge with liquid, the same as you must do with r410a.

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