    I sometimes do a quick method which is i take my suction pressure convert to temp. Measure my temp coming out of the evap coil and subtract the two.

    • 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.
