Introduction
Seeing puddles under your aircond? You're not alone.
Air conditioner water leaks are a common issue in Malaysia, especially during our hot and humid months. If your unit is leaking, don’t panic—many causes are fixable and avoidable with proper maintenance.
1. Clogged Drainage Pipe
Blocked pipes = water overflow
Over time, dust and algae can clog the aircond’s drain pipe, causing water to back up and leak out of the indoor unit.
Fix: A professional can flush the pipe using vacuum or pressure tools to restore proper flow.
2. Dirty Air Filter
Poor airflow = frozen coils = leaks
When filters are clogged, airflow is restricted. This can freeze the evaporator coil, and when it melts—hello, water leak.
Fix: Clean or replace filters every 1–2 months, especially during peak usage.
3. Low Refrigerant Levels
Less gas, more condensation
Insufficient refrigerant can drop pressure and cause the coils to freeze, leading to leaks.
Fix: Get a certified technician to check gas levels and recharge the system if needed.
4. Faulty Installation
Improper slope = drain issues
If your aircond unit wasn’t installed at the right angle, water might not drain properly.
Fix: Call a qualified installer to readjust the unit’s position or drainage slope.
5. Frozen Evaporator Coils
When things get too cold
Frozen coils are usually a sign of deeper problems like airflow issues or gas leaks.
Fix: Shut off the unit and get it inspected before further damage occurs.
6. Broken Drain Pan
Cracks = leaks
Older or corroded drain pans can develop cracks, causing collected water to spill out.
Fix: Replace the pan with a new one that fits your model.
7. High Humidity Levels
Malaysia’s climate contributes
On very humid days, your unit may produce excess condensation faster than it can drain.
Fix: Schedule regular maintenance and consider a unit with better dehumidifying features.
8. Poor Maintenance Schedule
Neglect causes issues
Many homeowners skip routine aircond servicing, allowing minor issues like clogs and dirty parts to escalate into leaks.
Fix: Stick to a maintenance schedule every 4–6 months to keep your system running smoothly.
9. Malfunctioning Thermostat
Wrong signals = wrong temperatures
A faulty thermostat can cause your unit to overwork, potentially leading to freezing coils and leaking water.
Fix: Have your thermostat tested and calibrated or replaced by a technician.
Why Timely Aircond Servicing Matters
Prevention is cheaper than repair
Regular aircond servicing can:
🧼 Prevent clogging and coil freeze
🧰 Catch installation errors early
💨 Improve airflow and cooling performance
🛠️ Extend your aircond lifespan
In Malaysia’s humid climate, servicing your unit every 4–6 months is highly recommended.
Did You Know?
Leaking airconds waste electricity ⚡
When your unit isn't working efficiently due to leaks or clogged parts, it uses more power to cool your room—raising your electricity bill!

Conclusion
A leaking aircond isn't just annoying—it can be a warning sign of bigger problems. From clogged pipes to low gas, identifying the cause early helps avoid costly repairs. Regular servicing is your best defence.
