You'll find that drying the home which has adapted to the humidity may present a few problems. Furniture and wooden floors will shrink some and may cause chairs to become loose and floors to gap. It's best to slowly drop the humidity and at constant levels. It's a good idea to keep the humidity at or near 45-55% for some time. Comfort zones are different as you dry the air. A home at 74 degrees with a humidity of 70% may feel muggy and warm, but at 45% feel very nice and cool. You may try a dehumidifier with the capacity for a room or two and see how that does first, but the house must be closed up and doing so may mean a warmer home. If it were me, I would try a window a/c combined with a dehumidifier and adjust the temperatures as needed. We are very humid here too and I seem to do well with 78 degrees with a humidity of 50% with the cieling fans operating. Reducing the amount of lights and appliances in the home will keep it cooler as well. Cieling fans will put out heat some, so they should run only when your in that room. Remember- an a/c must deal with removing the latent heat (humidity) before it will actually be able to cool the air in the home.

Zone controls are more complex, really not intended to be home owner serviced. It sounds to me like you have more than 1 problem with your zoned AC system. I service the Katy, Texas area.
