AC Problem

[cabinetman]

I have a split AC system 4 ton. The coils are an inverted "V" like this "^". The water is supposed to drip down and into a tray. When a certain fill level gets reached it flows into a condensate pump and gets pumped outside.

The tray has had a very slow dripping which I have a catch bucket collecting. Yesterday, I cleaned out the back section of the tray and evacuated the line and pathway to the pump. I couldn't get to the sides (without pulling it out), but they appeared clean. I still have a very slow drip. I'm thinking there may be still some obstruction on the side of the tray causing the water not to drain all the way back. Or, that there is so much water being removed from the air that it's just dripping right off the coils instead of making it to the tray. Any thoughts short of me pulling out the coils and checking the entire tray?

I had a friend with a similar problem.

I asked her when was the last time she changed the filter.

She said "there is a filter?"

When I changed it out, it looked like a piece of shag carpet.

With two large German Shepherds and three cats, we change the filter at least once a week, sometimes more often. I found with a clogged filter there is less air flow and the coils freeze up, and then there is no cold air. That's not the problem, but thanks for the suggestion.

Level

Another issue could be that the pan/A-coil is not level not slightly pitched toward the drain connection. Might have to take off cover to see if something is making a dam in there and letting water overflow before it can get to drain

A missing air conditioning system condensate drip tray risks leaks into the attic ceiling, where air conditioner condensate can damage the building or cause a (hidden) mold problem, especially if condensate is leaking onto the upper, hidden (by insulation) attic side of drywall forming a ceiling of a room located below the equipment. Both the drywall and the insulation itself may become mold reservoirs.
