AC Water Leakage in Kadapa: Causes, Fixes & Repair Cost
Water dripping from your indoor split AC is one of the most common complaints we get across Kadapa — and one of the easiest to fix once you understand what's actually happening. This guide walks you through the 6 real causes, what you can check yourself in 10 minutes, and what professional AC water leakage repair costs in Kadapa.
Where does AC water actually come from?
An air conditioner doesn't just cool air — it dehumidifies it. Warm air from your room passes over the cold indoor coil, and the moisture in that air condenses into water droplets on the coil's fins (exactly like water beading on a cold glass).
This water collects in a small plastic tray under the coil and flows out through a drain pipe to the outside. A 1.5 ton AC can produce 1.5–3 litres of water per dayin Kadapa's humid pre-monsoon weather. As long as that water exits outside, everything is normal. Leakage inside the room means the drain path is broken somewhere.
The 6 causes of AC water leakage in Kadapa
- Blocked drain pipe (most common in Kadapa) — algae, dust or insects plug the outlet. Water backs up into the tray, then overflows into your room.
- Drain pipe with wrong slope — installer didn't give enough downward angle, so water sits in the pipe and seeps backwards.
- Dirty air filter — clogged filter starves the coil of airflow, coil temperature drops below freezing, ice builds up, then drips when it melts.
- Low refrigerant gas — same effect as dirty filter; coil freezes from low pressure, then floods when ice melts.
- Cracked drain tray — common in ACs older than 7–8 years; the plastic tray under the coil splits and water leaks straight onto the wall.
- Loose or disconnected drain pipe — the pipe behind the unit slipped off the indoor unit nozzle, often during cleaning.
In Kadapa specifically, drain blockages account for more than half of leakage calls — our dust and outdoor insects are aggressive about clogging drain outlets, especially when ACs sit unused through the cooler months.
Quick checks you can do yourself in 10 minutes
1. Wash the air filter. Open the indoor unit, slide out the mesh filter, rinse it under tap water, dry it, and slide it back. If it was choked with dust, the coil was probably freezing — leakage may stop immediately.
2. Check the drain outlet outside. Walk to where the drain pipe ends (usually behind the outdoor unit, sometimes near a wall outlet). With the AC running on Cool mode for 20 minutes, water should be dripping or trickling out. If it's bone dry, the pipe is blocked.
3. Try a wire or a blow. If the outdoor end is blocked, a length of stiff wire pushed gently up the pipe — or a strong blow into the outdoor end — often clears the obstruction. Water will rush out within seconds when the blockage breaks.
4. Look for ice on the copper pipe. Open the indoor unit's right side cover. If you see ice on the copper pipe entering the unit, the coil is freezing — needs a technician for gas top-up or coil cleaning.
When you need to call an AC technician
- Drain pipe needs proper downward slope (re-routing)
- Algae or insect blockage that wire can't clear (pressure flush)
- Cracked drain tray needs replacement
- Gas top-up if low refrigerant is freezing the coil
- Coil cleaning if dirt is causing freezing
- Sealing the joint where the drain pipe enters the indoor unit
- Replacing a corroded or split drain pipe end-to-end

Frequently Asked Questions
Why is water dripping from my split AC indoor unit?+
An AC naturally produces water — it's the moisture pulled out of your room air. Normally it drains outside through the drain pipe. Leakage inside happens when that pipe is blocked (algae, dust, insects), has wrong slope, or the indoor coil has frozen due to a dirty filter or low gas. In Kadapa we see drain blockages most often because of dust.
Is AC water leakage dangerous?+
Yes — not for you directly, but for your walls, ceiling, furniture and any electronics below the unit. Long-term water dripping rots plaster, stains paint and can short-circuit wall sockets. Also, the standing water in a blocked drain tray becomes a breeding ground for mosquitoes. Get it fixed within a week.
How much does AC water leakage repair cost in Kadapa?+
Most water leakage problems are fixed during a general AC service at ₹500 (filter clean, drain pipe flush, slope correction). If the drain tray is cracked or the pipe needs full replacement, expect ₹200–₹600 extra for materials. Diagnosis is free with any repair booking.
Can I fix AC water leakage myself?+
You can try two things safely: (1) wash the indoor air filter, and (2) walk to where the drain pipe ends outside and check if water is flowing. If the outside end is dry while the AC runs, the pipe is blocked — a piece of wire or a quick blow into the pipe often clears it. Anything beyond that needs a technician.
Why does my AC leak only sometimes?+
Two common reasons. First: a partially blocked drain — water builds up slowly, then overflows once the tray is full. Second: a frozen coil that drips only when the AC switches off and the ice melts. If your AC leaks more after switching off than during running, it's almost certainly a freezing issue caused by a dirty filter or low refrigerant.
Should I switch off my AC if it's leaking water?+
If the water is dripping inside the room, yes — switch it off and place a bucket under the unit until a technician arrives. Continued leakage will damage your wall and floor. If the water is only dripping outside (which is normal), no action needed.
