One more thing that can be checked. Everyone has talked about the poor HVAC tape application around the vents and the vents themselves plus the void at the end of the duct runs that needs to be filled. One more thing that should be done in that regard is pull your lower A/C cover and look at the HVAC taping done in there. It wasn't good in my unit; in fact if the cold air or return leak, I suspect the A/C won't work as well as it should. The job they did on mine at the factory was as miserable as in the vents. Buy some of this HVAC tape and redo in all areas mentioned if it needs it!
