One good reason to have a properly sized ac system is humidity control. When it runs, the evaporator coil temperature is below the dew point temperature. The result of this is that the moisture condensing on the evaporator decreases the moisture in the air. This would suggest a reduction in the humidity. This process cannot happen with an oversized ac unit, as the run cycles on them are too brief for this to happen. So keep that in mind when youre going shopping around.
