Introduction
You’re relaxing in your home when suddenly, you notice water dripping from your split AC’s indoor unit. It’s frustrating, right? A leaking AC can lead to water damage, mold growth, and inefficiency in cooling. The good news? You can fix this issue yourself in most cases without calling a technician.
In this guide, we’ll walk you through the possible causes and step-by-step solutions to stop the water leakage from your split AC.

Understanding Why Your AC is Leaking Water
Before fixing the issue, let’s understand why your AC might be dripping water inside. Here are the most common reasons:
- Clogged Drain Pipe: Over time, dirt and dust can block the drain pipe, preventing proper water drainage.
- Dirty Air Filters: When air filters get clogged, they obstruct airflow, causing ice formation, which later melts and drips.
- Low Refrigerant Levels: Low refrigerant can lead to ice buildup on the evaporator coil, which melts and leaks.
- Improper Installation: If the AC unit is not level, water might not drain properly, leading to leakage.
- Damaged or Loose Drain Pan: A cracked or misplaced drain pan can cause water to spill instead of flowing out.
Step-by-Step Fix for Water Dripping Issue
Now that you know the causes, let’s move on to how you can fix it.
1. Clean the Drain Pipe
- Turn off the AC and unplug it for safety.
- Locate the drain pipe at the back of the indoor unit.
- Use a vacuum cleaner or a thin wire to remove any blockage.
- Pour some warm water mixed with vinegar to clear out any stubborn dirt.
2. Wash the Air Filters
- Open the front cover of the AC.
- Carefully remove the air filters.
- Wash them under running water and let them dry completely before reinserting.
3. Check the Refrigerant Levels
- If you notice reduced cooling along with water leakage, the refrigerant level might be low.
- This issue requires professional help, so contact a technician for a gas refill.
4. Ensure Proper AC Installation
- Check if your AC is slightly tilted backward (towards the drain pipe) for proper drainage.
- If it is not, adjust the mounting to ensure correct positioning.
5. Inspect the Drain Pan
- Remove the AC’s front panel and check if the drain pan is cracked or misaligned.
- If cracked, replace it. If misaligned, adjust it properly so that water flows into the drain pipe.
Preventive Measures to Avoid Future AC Water Leakage
After fixing the issue, follow these preventive tips to ensure it doesn’t happen again:
✅ Clean the air filters every 2-3 weeks to avoid clogging.
✅ Flush the drain pipe every few months with water and vinegar to prevent blockages.
✅ Get your AC serviced twice a year to maintain refrigerant levels and prevent ice buildup.
✅ Ensure correct installation when buying a new AC or shifting the unit.
Frequently Asked Questions (FAQs)
Why does my AC leak water when turned off?
When an AC is off, condensation can accumulate due to high humidity. If the drain pipe is clogged, this water might start dripping inside.
Can I use my AC while it’s leaking water?
It’s best to turn it off and fix the issue first, as continuous leakage can cause water damage and affect the AC’s performance.
How do I know if my drain pipe is clogged?
If water is not draining outside and instead dripping from the indoor unit, your drain pipe is likely blocked.
When should I call a professional?
If cleaning the drain pipe and filters doesn’t solve the problem, or if you suspect refrigerant issues, call a professional for servicing.
Conclusion
A Water leakage in split AC is a common issue but is often easy to fix. By understanding the causes, following the step-by-step solutions, and taking preventive measures, you can keep your AC running smoothly without any Water leaks.
