Wall unit AC drips water inside
I have an AC unit in the wall that is 10 years old. The unit is dripping water inside the room when it's running.
I pulled the unit out of the sleeve and found the tray to be completely filled with water, and lots of junk everywhere.
It appears that the water has not been properly dispersing for years. There is no drain plug, so it's not an issue with a clog.

I am wondering why the unit became so dirty when there are no trees over the area, and no animal building a nest or anything.

I did take notice that there does not appear to be much of a downward tilt to the sleeve in the wall, and that might be the reason the water pools up away from the fan blade where it is supposed to be slung out of the unit.

I'm curious as to what the tilt angle of the AC unit should be, and if mine isn't sufficient, is there an easy fix, like inserting a shim in the right place?
If it were a window unit, I would be removing it after each summer, but since it's in the wall, it doesn't get removed.

Should these units be cleaned regularly, regardless?

Thanks for your help.

Yes, it should be slightly pitched away from the room, and there should be a weep hole in the casing, or a small tube/hose from the unit, the fan is not supposed to sling the water.

Air is dirty, and the condensate from the AC has very little velocity or force to drain off. Warm space...moisture...= goobers. Dirt and biological wet stew, that plugs up drains. Clean it up, put it back in and crank it up.

There are a few units out there that have "slinger" rings around the condenser fan blade and they are designed to assist in getting rid of some of that water. (I didnt design Must be some honorary canadian I know who came up with that lame design). But listen to 8 -ball, there has to be a track or a drain hole that is plugged up with dirt.

I had the unit outside and hosed it down really good. It looks good now, although there appears to be a lot of deterioration or at least discoloration of the fins on the condenser coils. There doesn't appear to be anything I can do about that.

As far as the slinger, I had an AC unit many years ago that had one, and I thought they still used them, although I never saw a ring around the fan blades.
I'm not sure where this "weep hole" is, but I suspect it's a small opening in one of the rear corners. There was a lot of junk back there, so I'm sure water was not "weeping" through.

There does appear to be a slight downward pitch in the sleeve, so I guess it's OK.

I guess I should pull the units out once a year, at the end of each cooling season and clean them out.
