Finding water around your indoor AC unit can be alarming, especially when you are not sure where it is coming from. Your air conditioner naturally removes moisture from the air, but that water should drain away properly. If you see water leaking from your AC, a drainage or system issue may be the cause.
Why Is Water Leaking From My AC?
As your AC cools your home, moisture in the air collects on the evaporator coil and becomes condensation. That water normally flows into a drain pan and leaves through the condensate drain line. When part of that process is interrupted, water can collect around the indoor unit or leak into your home.
What Causes an Air Conditioner to Leak Inside?
1. A Clogged AC Drain Line
A clogged AC drain line is one of the most common reasons for indoor leaking. Dirt, dust, or other buildup can block the line and prevent condensation from draining. As water backs up, it may overflow near the unit.
2. A Dirty Air Filter or Frozen Coil
A dirty air filter can restrict airflow across the system. In some cases, that can contribute to ice forming on the evaporator coil. When the ice melts, the extra water may overwhelm the drainage system. You can check whether the air filter looks dirty, but other causes of freezing should be diagnosed by a technician.
3. A Drain Pan or Condensate Pump Problem
A damaged drain pan can allow water to escape before it reaches the drain line. Some systems also use a condensate pump, and a problem with that component can keep water from draining correctly.
