Aircon leaking at home or at work? Ayafa Aircon provides fast, reliable water leak repair across Singapore. Whether it’s a drip, a puddle, or persistent moisture around your unit, we get to the root of the problem and fix it properly.

Why Your Aircon is Leaking Water in Singapore

Aircon water leakage is usually the result of condensation that has nowhere to go, or a fault somewhere in the system preventing proper drainage.

Singapore’s high humidity means air conditioning units work harder and produce significantly more condensation than in drier climates. When any part of the drainage system is compromised, that moisture has no clean exit and starts leaking into your space instead. 

Left unaddressed, what starts as a minor drip can lead to water damage, mould growth, ceiling stains, and repair bills that far outweigh the cost of fixing the leak early.

Common Causes of Aircon Water Leakage

Water leaks rarely have a single obvious cause. A proper inspection is the only reliable way to identify what’s actually going wrong before attempting a repair.

1. Clogged Drainage Pipe

Blocked drain pipes are the most frequent reason aircons leak. Over time, dirt, dust, and algae accumulate inside the drainage pipe and restrict water flow until it has nowhere to go but back into your room.

  • Dripping water from or near the indoor unit
  • Pooling water on the floor beneath the unit
  • Water stains around the unit’s housing

2. Dirty Air Filters or Coils

When air filters are clogged, airflow across the evaporator coil drops significantly. This causes the coil to drop below freezing, forming ice that eventually melts faster than the drain pan can handle.

  • Noticeably weak airflow from the unit
  • Water leaking some time after the unit has been switched off, as the ice thaws

3. Frozen Evaporator Coil

Low refrigerant levels or restricted airflow can cause the evaporator coil to freeze over entirely. When the unit cycles off and the ice begins to melt, the volume of water can overwhelm the drain pan and spill over.

  • Reduced or inconsistent cooling performance
  • Visible ice on the coil or refrigerant lines

4. Damaged or Misaligned Drain Pan

The drain pan sits beneath the evaporator coil to catch condensation. Cracks, rust, or a pan that has shifted out of position means water misses the pan entirely and leaks internally.

  • Continuous dripping that doesn’t stop after cleaning the drain pipe
  • Signs of water damage inside the unit’s casing

5. Improper Installation or Tilt

An aircon unit that was installed at the wrong angle won’t drain correctly. Instead of flowing toward the drain outlet, water moves in the wrong direction and drips indoors.

  • Consistent dripping from the indoor unit regardless of maintenance history
  • Issues that started shortly after a new installation or reinstallation

Signs Your Aircon Needs Immediate Leak Repair

Some aircon issues can wait. Water leakage is not one of them. Here are the signs that it’s time to book a repair sooner rather than later.

  • Water Dripping from the Indoor Unit: Any visible dripping from the unit itself points to a drainage problem that needs attention before it causes secondary damage to walls, ceilings, or floors.
  • Pooling Water Near the Unit: Standing water around the base of your indoor unit suggests drainage has failed entirely and the situation is likely getting worse.
  • Musty or Damp Smell: A persistent musty odour often means moisture is sitting somewhere it shouldn’t be, encouraging mould or mildew growth inside the unit or surrounding area.
  • Reduced Cooling Performance: If your aircon is leaking and not cooling as effectively as it should, the two issues are often connected, usually through a frozen coil or refrigerant problem.
  • Unusual Sounds During Operation: Gurgling or dripping sounds from inside the unit while it’s running often indicate water is moving through areas it isn’t supposed to reach.

Aircon Leaking Repair Cost Singapore

Repair costs vary depending on the cause and complexity of the leak. The table below gives a general guide to what different types of repairs typically involve and what you can expect to pay.

Repair Type

What’s Involved

Estimated Price Range

Basic Drain Clearing

Vacuuming and flushing the drainage pipe to restore water flow

From $40

Priced based on assessment

Minor drainage fixes are generally affordable, while more involved repairs involving parts replacement or a full overhaul will vary depending on the severity of the fault and the components required. If you’re unsure what your unit needs, Ayafa Aircon will assess and advise before any work begins.

How Aircon Water Leaks are Fixed

  1. Inspection: The technician examines the indoor unit, drainage system, filters, coils, and drain pan to assess the extent of the leak and identify any visible damage.
  2. Root Cause Identification: Based on the inspection, the specific cause of the leak is confirmed, whether it’s a blocked drain, frozen coil, refrigerant issue, or a physical fault.
  3. Drain Clearing: If the drainage pipe or tray is blocked, it is vacuumed and flushed to restore proper water flow.
  4. Component Cleaning: Filters, coils, and the drain pan are cleaned to remove the buildup that may have caused or worsened the leak.
  5. Parts Repair or Replacement: Any damaged components such as cracked drain pans, faulty bearings, or misaligned fittings are repaired or replaced as needed.
  6. System Testing: Once repairs are complete, the unit is run to confirm the leak has been resolved and that cooling performance is back to normal.

How to Prevent Aircon Water Leakage

Routine care goes a long way in keeping your aircon leak-free. A few straightforward habits can prevent most common causes from developing in the first place.

  • Service Your Aircon Regularly: Schedule general servicing every three months. Regular servicing includes drainage checks, filter cleaning, and coil inspection, all of which directly reduce the risk of leaks.
  • Clean or Replace Filters: Dirty filters are one of the most preventable causes of leaks. Check them monthly and clean or replace as needed to maintain healthy airflow.
  • Do Not Set the Temperature Too Low: Running your aircon at very low temperatures for extended periods increases the risk of coil freezing, particularly in units that already have marginal airflow.
  • Keep the Area Around the Unit Clear: Blocked vents or obstructions near the unit restrict airflow and make it harder for the system to manage condensation effectively.
  • Monitor for Early Warning Signs: Catching a small drip early is far easier and less costly to deal with than waiting until it becomes a persistent leak.

Staying on top of maintenance is the most reliable way to avoid repeat leaks and the disruption that comes with them.

Frequently Asked Questions

Why is my aircon leaking water inside?

Indoor leaks are almost always caused by drainage issues, such as a blocked drain pipe, a dirty or frozen evaporator coil, or a damaged drain pan. Singapore’s humidity means units produce a lot of condensation, so when drainage fails even slightly, water shows up quickly.

A clogged drainage pipe is the most frequent culprit. Dirt, dust, and algae build up over time inside the pipe and prevent condensation from draining away properly.

Minor fixes like drain clearing typically start from around $40. More involved repairs such as a chemical wash or overhaul range from $70 to $170 or more per unit, depending on what’s required.

It’s best not to. Continued use can worsen the underlying fault, cause water damage to your walls and ceiling, and in some cases create electrical hazards. Switch it off and arrange a repair promptly.

Most straightforward leaks, such as a blocked drain or dirty filters, can be resolved in a single visit. More complex faults may require parts or a follow-up appointment, but our team will let you know upfront.

In many cases, yes. A general service includes drain clearing, filter cleaning, and coil inspection, which addresses the most common causes of leaks. If the issue is more serious, such as a cracked drain pan or refrigerant fault, additional repair work will be needed.

Water leaking near electrical components is a safety risk. Beyond that, prolonged moisture exposure can cause mould growth, ceiling damage, and structural issues over time. It’s not something to leave unattended.

Call a technician as soon as you notice consistent dripping, pooling water, or a musty smell coming from your unit. The sooner the issue is assessed, the less likely it is to develop into something more costly.
