If those high ceilings are directly under the roof, don't run that ceiling fan that is pulling cold air up to the ceiling ! You will be greatly increasing the heat transfer from the roof . Unless you have some other reason, you want that to be dead air and allow the warmest room air to collect there.
6 degree increase in average temp will require your system to run more. Have you lost any shade trees in the last year ?
Take a look at the freon liquid line (small) inlet at the evaporator in the attic (or wherever it is inside the condo). If you see ice there, i would suspect you have very little freon. If the compressor seems to never shut off - runs for hours just to maintain temperature - low freon. Most systems run around 15-30 minutes to maintain temperature. Less than that will have a hard time controlling internal humidity (unless you are in a dry climate). IF your system has an expansion valve at the evaporator, it could be plugged partially - ice on the valve is a good sign.
The other thing to look for is a busted/large leak on the pressure side duct - ie you are cooling the attic ! Or you could have a break in the return air to the blower and be pulling air into the condo from outside.
Get a tech to read the pressures and go from there. He can also spend an hour and try to find the leak on the coils if you have to repeatedly refill the system.
Good luck.
