    If you don't know, then don't do. If you don't know and still do, then be prepared to pay someone else a lot to undo what you did and then do it right.

    If you do know, then do. But do it right. Otherwise, you may not be doing it long.

    False... if you're running the furnace (no A/C) there's no way it could be

    (At Least) one wiseguy in every crowd... let's assume its summertime and its 75 degrees and 55% relative humidity in the house and the A/C is running with an evaporator temperature of 45 degrees.

    True or False... Air leaving the evaporator coil is at 100% relative humidity

    In order to remove moisture from the air, the air must be cooled below
    the dewpoint. For example 75 degree air entering a 45 degree evaporator
    coil at 55% relative humidity and exiting the evaporator at 55 degrees.
    The air is now below the dewpoint so the wet bulb and dry bulb temperatures
    are the same... If the wet bulb and dry bulb temperatures are the same,
    you are also at 100% humidity.

    The answer is True

    Bypass factor


    never seen wb and db temps the same exiting the evap


    Your theory would be correct if you could have 100% of the air move across the surface of the coil.
