The relative humidity is the amount of moisture in the air "relative" to the amount of moisture that the air is capable of holding at the temperature of the air. So, if the relative humidity is 50 percent, it means that the air is holding half of the amount of moisture that it is capable of holding without becoming saturated.

An a.c. Unit does remove humidity, a fancy thermostat gives you more information on how the a.c. Is performing in your home. There are hundreds of websites that discuss this. A.c. Dehumidifies passively, but you will probably be running your a.c. Anyways. So you will dehumidify even if that is not what you intend to do. The question is is that low enough humidity for you. If you have spent time in a hotel or just about any other public building you have a point of reference if the humidity relief is great enough.
