How to do about a central air duct leaking above the ceiling

air-conditioningcentral-airleak

My closet ceiling is leaking a brown liquid. Right above it is an air duct for my central air. I think the liquid is dirty or rusty water that has accumulated in the duct. I can hear it dripping inside the duct.

I live in a rented apartment so they will come check it out soon. I would like to know what I can do immediately to alleviate the problem. I have my A/C set to 75 °F– the temperature outside reaches 90 °F most days. If I shut it off completely, will the leak dry up? Is there anything else I can do?

It sounds like you have a condensation draining problem. Air conditioners capture a lot of water from the air. Most of the time A/C water leaks are caused by a problem draining this condensation. Stopping the a/c will stop the condensation, and eventually (depending on how much water is backed-up) the unit will stop leaking.
