Central AC froze up and...

...now it's leaking from the inside portion of the unit.

What would cause this?

By the way, I'm in South Korea, so I really don't want some serviceman telling my wife (in South Georgia) that something is totally screwed when it isn't.

Drip pan is full of water and the drain is plugged up. Or inside coil is plugged up with dirt.

Check drip pan. Turn off the power to the outside unit and put the fan to on so that the inside unit fan will run. That will help melt the ice faster. If water is in the drip pan, unplug the drain.

To be clear, it froze up Saturday night, but is leaking now.

Coil may need cleaning so air can blow through better and un-freeze it.

Leaking could be water from drip pan beneath the unit - if the drain is plugged, blow a little air through it and pour some Clorox bleach in it to knock out the buildup that may be the source of the clog.

Maybe someone in this planet who know A/C repair can do a facetime or skype. Otherwise just get a repairman and have he call you when he's talking price.

When's the last time the filter was changed? Dirty filter can restrict air flow, causing unit to freeze.

if i understand correctly, what you see is not a leak but the ice on the coils melting.

after it thaws, spray the coils with a coil cleaner.

Yep, that's probably it... I just talked to my father in law in S'port and he said it's probably low on Freon and to do a service call to have them check it out and top it off.

Sucks. Joys of owning a house and not being around to fix it.

As others have said, the coil is likely clogged. This resulted in freezing, which resulted in more clogging, resulting in more freezing.

Without proper airflow through the coil, the refrigerant remains too cold when it goes back through the compressor and condenser. Then it goes back through the coil super fricking cold and will freeze shite.

Your a/c unit is fine, your wife is railing the repairman and this is her excuse to have him over.

The OT is slacking.

dirty Evaporator and or Condenser coil will cause freeze ups. It's not always a low freon problem.

Clean evaporator, change filter, and recharge system with Freon and you will be good to go

Happened to me just like that.

My a/c quit because the drip pan was full. There is an overflow sensor that shuts off something when the water gets too high. Then the coil, which is frozen up, thaws and it overflows.

I could get it running again by bailing out the drip pan. But eventually I had to replace the coil. It ain't cheap. Sorry, bro.

There's two pans in the system. One is internal to the evaporator unit and is supposed to drain properly.If it is not draining properly cold water will accumulate in the bottom of the unit causing condensation to form on the underside of the unit.
This condensation will then drip into the pan below and if something isn't done to fix the problem it will fill up.
The drip pan often is not plumed for drainage since it's the only way you would know there's something wrong with the system.

OP,I would think if the pan is full then the main evap unit is not draining properly.

So, evap cooler is leaking. So far, it's $350 for labor, part is covered under warranty, plus the price of freon... sound fair?

this, fix it yourself for free, this is very common when it runs for long periods of time.
