You are sitting under the AC and notice a steady drip of water landing on the floor or soaking into your wall. The AC is cooling — maybe even cooling well — but water is coming from inside the unit. This is one of the most common complaints we handle in Samastipur, especially in peak summer when ACs run 18+ hours a day.
The good news: most AC water dripping problems are not expensive to fix. The bad news: if you ignore them, water damage to walls, ceilings, and electrical fittings can cost far more than the original repair. Here is the full breakdown from a technician's perspective.
Every split AC has a condensate drain pipe — a small tube (usually 16–20mm diameter) that carries the water produced by the cooling process from the indoor unit to outside the wall. In Samastipur, this pipe runs through the wall and often exits into an open drain or outside.
Over time, algae, dust, and mineral deposits build up inside this pipe until it becomes partially or fully blocked. When blocked, the water produced by the AC has nowhere to go — it fills the drain tray inside the unit, overflows, and drips through the front louvres into the room.
Signs: Steady drip directly below the indoor unit, sometimes gurgling sound from the unit, water stain on the wall below the AC.
Fix: Drain pipe cleaning — we use a wet vacuum or pressurised water flush to clear the blockage. Takes 15–20 minutes. Cost: ₹200–₹400. This is included in our full AC service package.
Prevention: Pour a small amount of diluted bleach or vinegar into the drain tray every 2 months during summer — it prevents algae growth that causes most blockages.
When the evaporator coil (the cold part inside the indoor unit) gets too cold and freezes over, it builds up a thick layer of ice. When you switch the AC off or the compressor cycles down, all that ice melts at once — far more water than the drain tray is designed to handle. The tray floods and water pours out of the unit.
This typically happens because of severely restricted airflow (clogged filter or blocked return air) or low refrigerant gas — both cause the coil temperature to drop below freezing.
Signs: Very little air from the indoor unit despite fan running high, water dripping heavily when AC switches off or defrosts, visible frost on the copper pipe near the indoor unit.
Fix: Address the underlying cause — clean the filter, or refill the refrigerant gas. The ice melting problem stops once the root cause is fixed.
The indoor unit of a split AC must be installed with a very slight backward tilt — about 2–3 degrees — so that condensate water flows toward the drain outlet at the back of the unit. If the unit was installed perfectly level or with a forward tilt, the water sits in the tray and slowly overflows toward the front of the unit instead of draining out.
This problem is surprisingly common in Samastipur homes where AC installation was done by unqualified workers who did not use a spirit level. The AC may have been dripping from day one, or it may start after the mounting surface settles slightly over time.
Signs: Water dripping from the front edge of the indoor unit, problem started shortly after installation or after the AC was reinstalled.
Fix: Re-level the mounting bracket. Quick job — 20 minutes. Cost: ₹200–₹350 service charge.
The drain tray is a plastic component inside the indoor unit that collects condensate water before it flows into the drain pipe. In older ACs (5+ years), this plastic can crack due to temperature cycling stress, or the drain outlet hole can erode enough that water bypasses the pipe connection and drips straight down.
Signs: Dripping continues even after drain pipe is cleared, water appears to come from a slightly different location than the pipe outlet — often more toward the centre of the unit.
Fix: Drain tray replacement or repair with waterproof sealant (for small cracks). Tray replacement ₹400–₹900 depending on AC model. We carry trays for LG, Voltas, Samsung, Daikin, and Carrier.
This connects to Cause 02 but deserves its own entry because it is so fixable at home. A filter that is 60–80% blocked with dust drastically reduces airflow over the evaporator coil. The coil becomes so cold it freezes. Every 30–40 minutes the compressor cycles off, the ice melts, and you get a burst of water dripping out.
Many people in Samastipur see this pattern: AC runs for a while, then water suddenly drips heavily for 5–10 minutes, then stops — then repeats. This is the freeze-melt cycle caused by a dirty filter.
Fix yourself: Remove and wash the filter. Allow it to dry fully. If the dripping stops after this, you have solved it for free.
