    A/C Icing Over
    Our window unit's grill freezes over at least once/day.
    I have continually cleaned the filter, and gave the grill the time to thaw and dry.
    But still it happens.

    If the outdoor temperature is to cool many times a window unit will freeze over.

    OR

    The evaporator could be dirty

    OR

    The unit might have a small leak and be a bit short of refrigerant. It does not take much of a leak on a window unit to cause this problem.

    If the coil, is not dirty sounds like it may be time for a new unit.
