Seeing water leaking from your air conditioner inside your home can be alarming. Many homeowners search “AC leaking water inside” or “water dripping from air conditioner” when they notice puddles near the indoor unit, water stains on ceilings, or damp flooring.
Indoor AC leaks almost always point to drainage problems, airflow restrictions, or freezing issues. While a small drip may seem harmless, ignoring it can lead to water damage and system failure.
Air conditioners remove humidity from the air, producing condensation that must drain properly. When drainage fails or airflow drops, water backs up and leaks into the home.
Leaks are a sign the system isn’t managing moisture correctly.
The most common cause of indoor AC leaks is a clogged drain line. Dirt, algae, and debris can block drainage and force water to overflow.
Drain clogs often worsen quickly.
When airflow is restricted or refrigerant is low, the evaporator coil can freeze. As it thaws, excess water may overwhelm the drain pan and leak inside.
Freezing issues usually repeat without repair.
Older drain pans can crack or rust, allowing water to leak before it reaches the drain line.
Drain pan damage is common in aging systems.
Drain lines must be installed with the proper slope to allow water to flow out naturally. Poor installation can cause standing water and leaks.
Installation quality affects drainage performance.
Clogged filters restrict airflow, increasing condensation and freezing risk—both of which contribute to leaks.
Filter replacement helps reduce moisture buildup.
Excess humidity increases condensation volume, which can overwhelm the drain system if other issues exist.
Humidity control supports proper drainage.
Without routine maintenance, small drainage issues often go unnoticed until water damage occurs.
Maintenance helps prevent leaks before they start.
Ignoring indoor AC leaks can lead to:
Water damage escalates quickly.
If your AC is leaking water inside:
Quick action limits damage.
Routine HVAC maintenance includes drain line flushing, airflow testing, coil inspection, and moisture management checks. Maintenance keeps water flowing safely out of the system.
Maintained systems handle condensation properly.
