Air Conditioning - Helping buddy new issue (Air conditioner excess water)

Ok awhile back I posted questions about a blower motor that kept cycling on and off. Got that solved with a new start CAP. Now a new issue has arouse. When the a/c is running, water comes splahing out from around the drip pan. ( blower is directly underneath the coil) Lots of water! I have checked the drain lines, and they are functioning normally. The unit has a furnace as well, and there is a open winter close summer lever that is just to the right of the coil. When the lever is closed, the water splashes and leaks all over the place. When it is open the coil freezes up solid and the outside unit freezes as well.
I've been reading posts, and it sounds like my buddy may be low on freon. The fins are all clean looking, I looked as close as I could, and saw no dust build up. Please let me know what you think, or ask questions to try to narrow it down. Thanks for your help on the motor/CAP question.

Thanks again for your help.

Just what do you have there. Is this open or close on a humidifier???? if this is a bypass yes the coil can frezze. Is the drain pan clean ?? the coil clean ??check the air in-side of the coil for dirt build up.

This is an old carrier furnace that has had air added later. The blower unit is on the very bottom, then you have the furnace part then the evaporator/coil. The pan is more like a lip that goes around the outside diameter of the coil. When the water actually makes it to the pan it will run out of the white pvc pipe with no trouble. I have even ran water through it make sure it is flowing ok.

The blower blows up over the coil. The air is then pushed out to the vents. Except in this case it has such an excess of water dripping off the coil it blows it all over the casing of the central air unit.

The flap with the handle (open winter/closed summer) Is a bypass for the furnace.(as I had stated air added years after furnace install)

How would you check the coil on the inside without completely taking it out of the housing?

So what would cause the large amounts of water coming off the coil?

Is there a humidifier there on the furnace ??? is the water to it on????

ED

there is a humidifier, but my buddy says that he turned the water off along time ago.

Oh forgot to mention that it does not leak until a/c is turned on

You didnt check the coil is it clean??? Dirt on or in the coil. algae build up in the drain pan

When the lever is closed, the water splashes and leaks all over the place. When it is open the coil freezes up solid and the outside unit freezes as well.

Clean the coil first.

Thanks, I had asked before, on how to check the inside of the coil without taking the whole thing out. The a/c was working fine before the whole CAP/ blower motor went bad. The coil is set up in an A frame style, and all the fins look clean. The only thing that I can see that is different, is a small gap in the panel that covers the coil area. When we took it off there was a line of silicone around one side, and now that we took the panel off, the seal of course had been broken. Could this be part of it? or low freon? I really do count on you for your knowledge and input. Thanks again.

Is the A-coil covered in Ice and the large copper line iced over that enters the A- coil? That same line should have ice on it at the outside condensing unit. If the a-coil is ice covered then no air can pass through it and it is just blowing the water from melting ice around. I'm not sure what you mean by a lever for winter and summer. At anyrate does the unit ever cycle? Or does it just run constantly?

It will cycle off and on. The issue is that when all is like it was prior to the capacitor failure, then we get copious amounts of water splashing all around the drip pan. It's like there is so much air moving over the coil area that the water that normally would go into the drip pan gets blown out onto the casing of the central air unit. Do you have to remove the coil on this style to check for cleanliness?

You dont have to remove it. How good is your air flow at a registar? If the thing is cooling normal then I'd say you just have an obstruction that is not letting it drain properly. The drain pan should handle any water that condenses when operating the A/c. Or you have a pan that is not sitting properly and wont drain the water. Is the furnace part sitting on spacers..like bricks or the like?
