Almost all ducted a/c systems are not sealed well at all. First, remove the cover over the inside a/c unit and note that there was a feeble attempt to seal between inlet side and exhaust side. Buy some A/C vent tape and fix the problem. Also note where the outlet duct enters the ductwork, this may also need some sealing. Pull off all overhead vents and note that the sealing with A/C tape is similarly poorly done. Some folks put a barrier (styrofoam is the material of choice) at the ends of the run if the duct just dumps in to the void beyond. Cleaning up the sealing issue greatly enhances the effectiveness of the A/C system.
