Why is my AC leaking water, or why is ice forming on it?

A clogged drain line is the most common cause of water leaking from the indoor unit — often fixable by clearing the drain outlet. Ice forming on the unit usually means restricted airflow (again, often a dirty filter) or low refrigerant. If you see ice, turn the AC off and let it thaw naturally rather than continuing to run it — running an AC while it's actively icing up can cause more damage.

These two symptoms are connected more often than people expect — ice that forms during operation melts once you turn the unit off, and that meltwater is a common source of what looks like a separate "leaking" problem. Checking and cleaning the filter addresses the root cause behind a real share of both symptoms; if the leak or icing continues after a clean filter and a proper thaw cycle, that points to low refrigerant or a drain blockage deeper in the system, which needs a technician rather than further self-diagnosis.
