Water near the unit
Stop cooling if water is reaching electrical components or spreading into floors, insulation, or drywall.

A/C Condensate Water & Leaks
Water near an air handler, a ceiling stain, or an overflowing auxiliary drain all deserve attention. Trace the source before assuming the pipe is the only cause.

A ceiling stain appeared
Water can travel along framing before it becomes visible. The stain may be far from the actual failure.
A secondary drain is dripping
An emergency outlet that suddenly runs can indicate the primary drainage path is not working normally.
Follow the water upstream
Begin at the wettest safe point and work back toward the indoor coil. Check the primary pan, auxiliary pan, drain connections, float switch, trap, pump, and visible pipe joints. Do not open wet electrical compartments.
A condensate clog is common, but it is not the only explanation. Coil ice can melt into a large volume of water. A cracked pan, loose fitting, sweating duct, or failed pump can also leave water around the equipment.
Protect the home before diagnosing the detail
If water is spreading, turn the system off and protect the area below it. Do not walk on wet ceiling material or reach through soaked insulation. A technician can remove standing water, test the drain path, and identify damage that is hidden from view.
Once the line is flowing and the installation is sound, regular inspection and preventative drain care can reduce the chance of another surprise.
