Something you might want to try is a small Dehumidifier. A neighbor was telling me that they had a problem with the master bedroom not being comfortable on the days that the A/C unit did not run much.
To try to make things better they bought a small dehumidifier from Amazon for about $ 45 and really liked the improved comfort.
I also bought one and like how much water it takes out of the air in the house. It has a 16 oz container that fills up in 4 to 7 days. It is fairly quite [ours is in the den about 5 -8 feet from where we watch TV] and is small [6"W X 8.5"H X 5"D].
