Why Is Water Leaking From My AC?
A central air conditioner creates condensation as it removes humidity from the air, so some water is normal inside the system. Water where it does not belong is not.
Simple rule: If your AC is leaking water indoors, the most common culprits are drain problems, frozen coils thawing, or a condensate component that is not doing its job.
Condensation Is Normal — Overflow Is Not
During normal cooling, moisture collects on the indoor coil and drains away through the condensate system.
If that drainage path clogs, disconnects, cracks, or backs up, the water ends up where you can see it.
Clogged Drain Lines Are Very Common
One of the most common causes of indoor AC water leaks is a clogged condensate drain line.
When the line backs up, the system may drip into the auxiliary pan, leak around the air handler, or trip a safety switch if one is installed.
A Frozen Coil Can Create a Water Leak Too
If the system has been freezing up and then thaws, all of that ice can turn into a surprising amount of water.
In those cases, the visible leak is often the symptom you notice first, but the original problem may have been airflow or refrigerant related.
Drain Pan and Pump Problems
Older or damaged drain pans can rust through or crack. In some homes, a condensate pump also plays a role, and a pump issue can lead to overflow.
If the drainage components are not doing their job, the water has to go somewhere.
What to Do When You Notice Water
If you see active leaking, turn the system off if needed to prevent more water damage, then check around the indoor unit for obvious standing water.
If the leak is recurring, it needs to be corrected at the source rather than simply dried up each time.
