You likely either need to clean the drainage hole in the pan or the drainage hose out with compressed air.

The pan is under the evaporator coil.
You can try suction on the drain line with a shop vac.

Attached are some pics.

Thanks roughneck77 I used the vacuum a while back for about 30 minutes or so to drain all water out and poured with Clog remover liquid and also vinegar.

Is there a Fan Filter for this AC Unit?

Yes, there is a filter. Should be changed every 3 months. I hope you’ve changed it before

Is that the only drain line connected ?
It doesn't look like it connects to anything.

It looks like the return may come up from below. The filter should be in the return line.

I only see a 6" piece of PVC. Where's the rest of it ?
Where is the water draining too ?

Is there another line elsewhere that we can't see in the pictures ?
That may be a dead end fitting for a float switch.

NO.... use no drain cleaners.

Ok..... much better. I didn't see the primary drain line as it's in that black foam.
That line is what is clogged. The 6" 'PVC fitting is the overflow or secondary drain line.

You need to find out where that lines goes in the wall. That is the line that is clogged.
It's PVC.... it may have to be cut open in order to clean it.

Thanks Pete I used a water vacuum for drain line outside my house and for now luckily so far I don't see any water is being stagnant or leaking.

now I am wondering if I have to do some maintenance like cleaning "Fan Coil Filter" is that some where to be found or cleaning the coils by opening the UNIT...what your expert advise

So you’ve never changed a filter ever in this unit?
How long have you lived here?

There should only be one filter. It will be in the return line. It may be behind a large return grill in a wall. It should look like a typical furnace filter. It won't be inside the air handler. It will be external.

You can "clean" the drain pan by removing that float switch, pouring in one cup of bleach and then flushing it with at least a gallon of water. The bleach will flush the algae and muck out of that area of the pan. Best to do it when the A/C won't be used for a day or two to allow the bleach to drain out.
