My AC started to blow out pretty lukewarm air recently, as well as make watery sounds while running. I realized the filter was dirty, and I cleaned the coils, replaced the filter and removed lots of water from the drip pan. I was able to get an improvement in cold air and no watery noise. However, after about 6 hours of use, I started to hear the watery sounds again and noticed the drip pan was full. I imagine the drainage in the unit is clogged. Unfortunately, I live on the 7th floor of a building, so taking the unit out can be quite cumbersome. Are there any methods to fix the problem? Would pouring some bleach into the pan do the trick?
Update: I drained the drainage pan again and saw that the AC unit was regurgitating water.

For servicing the workings of the whole unit can be taken indoors by undoing fastenings located indoors, leaving just the shell outside, you don't need the power of flight, but you do need to be strong, or gang up on it.
Some designs spray excess condensate water on the condenser coils to improve efficiency, the watery sound may be normal.
