5 Causes — AC Water Dripping Inside Room in Samastipur
Blocked Drain Pipe — Most Common in Samastipur
Every split AC has a drain pipe that carries condensed water outside. In Samastipur, heavy dust, algae growth (from humidity), and debris block this pipe quickly — especially in summer. When blocked, water has nowhere to go and overflows from the indoor unit tray.
How to confirm: No water dripping outside from the drain pipe — but dripping inside the room.
Fix ₹300–₹700Frozen Evaporator Coil Thawing
When refrigerant gas is low, the evaporator coil freezes over. When the AC switches off, the ice melts rapidly — releasing much more water than the drain pan can handle. You'll notice water only when the AC is off or just turned off, not while running.
Related issue: Your AC isn't cooling properly either — low gas causes both problems.
Fix ₹700–₹1,600 (gas refill + leak fix)Incorrect Installation Tilt
The indoor unit must be slightly tilted toward the drain side (usually 2-3 degrees). If installed incorrectly or if the wall bracket has shifted, water pools on the wrong side and drips inside. Very common in older installations in Samastipur homes.
Fix ₹400–₹800 (re-tilting & bracket adjustment)Dirty/Clogged Air Filter
A choked filter blocks airflow over the evaporator coil. The coil gets too cold, freezes, then thaws — dumping excess water. Clean your filter every month in Samastipur (dust is heavy here). See our guide: AC not cooling Samastipur for filter cleaning steps.
DIY: Free · Coil clean by tech: ₹400–₹800Cracked or Rusted Drain Pan
The drain pan (under the evaporator coil) catches water before it flows out. In older ACs (5+ years), the pan can crack or rust — water leaks directly through. More common in Samastipur due to hard water mineral deposits corroding the pan.
