I assume you have two a/c's? If so keep the temp setting of he front one the lowest or at least the same. I keep my front a/c on 75 or 76 and the rear one the same or 76 when the front one is on 75. If I put the rear one lower than the front condensation can occur. I am in Panama City Beach where it is HOT and HUMID just like your area.
