Why Is My AC Leaking Water? Common Causes & How to Fix It

If you notice water pooling around your air conditioner, it’s a sign that something isn’t working correctly. While AC systems naturally produce condensation, that moisture should be properly drained away. When it isn’t, it can lead to water damage, mold growth, and system inefficiency.

Common Causes of AC Water Leaks

Clogged Drain Line

The most common cause of leaks is a clogged condensate drain line. Dirt, dust, and debris can block the line, causing water to back up into your home.

Frozen Evaporator Coil

When airflow is restricted or refrigerant levels are low, the evaporator coil can freeze. As it melts, excess water may overflow the drain pan.

Damaged Drain Pan

Older systems may have rusted or cracked drain pans that allow water to escape instead of draining properly.

Dirty Air Filters

Restricted airflow can lead to freezing and excess condensation, which contributes to leaking issues.

When to Call for AC Repair

If cleaning the filter doesn’t resolve the issue, it’s best to schedule professional air conditioning repair in San Gabriel, CA. Technicians can safely clear blockages and inspect for deeper system issues.

How to Prevent AC Leaks

Routine maintenance, including cleaning drain lines and replacing filters, can help prevent leaks and keep your system running efficiently.
