You will get more condisate if the A coil is dirty. there's another fin filter right above or below the blower depending if you have an updraft or down draft system. If this gets dirty just as bad as a coil. You'll have to pull the blower to get to it. While your at it you can clean the blower.I have a clean out port. I was able to use a sink snake and unplug it. Nasty black algae chunks came out followed by water. Explains why the Evaporator was freezing from the bottom up I suppose. And why the inside was always wet.
Every year I pull apart and clean it
