Water leaking from an air conditioner is a common issue among homeowners and businesses in Singapore. The leak usually stems from a lack of maintenance or underlying system faults. If left unresolved, the leak can lead to water stains, mould growth, and even property damage. Understanding the root causes and recognising when to schedule an air conditioning service can help prevent bigger problems. This guide outlines the usual suspects behind an aircon leaking water and provides straightforward solutions.
1. Clogged or Disconnected Drainage Pipe
A blocked or dislodged drainage pipe is one of the most common reasons for water leakage. When the drainage system is clogged with dirt, algae, or mould, the condensation formed during cooling cannot exit properly. As a result, water backs up and starts dripping from the unit’s casing. The pipe may also become loose or detached due to poor installation or wear and tear.
This issue can usually be resolved during routine aircon servicing in Singapore. Technicians flush the pipe using pressurised water or cleaning agents to clear blockages and ensure smooth water flow. If the pipe is damaged, they will recommend replacement to prevent further leaks. Regular servicing helps prevent this problem from recurring.
2. Dirty Air Filters and Coils
When air filters are clogged with dust and debris, they obstruct airflow, which can cause the evaporator coil to freeze. When the ice melts, excess water may overflow the drain pan and leak out of the unit. Similarly, dirty evaporator coils lose their cooling efficiency, leading to condensation build-up that can’t drain properly.
Scheduling regular air conditioning service that includes filter cleaning and coil inspection is essential. Homeowners should clean or replace filters every one to two months, while professional servicing should occur at least every three to six months depending on usage. This reduces the possibility of a freezing and leaking unit.
3. Low Refrigerant Levels
Low refrigerant levels reduce the pressure in the aircon system, which can cause the evaporator coil to freeze. When the coil eventually thaws, the resulting water may exceed the drainage capacity and spill out. This is a cause of water leakage and a sign that the unit is not cooling efficiently.
If your system is underperforming and you suspect a refrigerant issue, schedule aircon servicing in Singapore promptly. Technicians will check for leaks, replace the refrigerant if critical, and ensure your system is functioning.
4. Full or Damaged Drain Pan
The drain pan collects condensation during the cooling process and channels it to the drainage pipe. Over time, it may become rusty, cracked, or misaligned, especially in older units. If the pan is full due to a blocked pipe or if it’s damaged, it won’t hold water effectively, resulting in leaks.
A technician can inspect the pan during a servicing session and determine whether cleaning, resealing, or replacing is required. This part of the service is important for units over five years old. Neglecting the issue raises the possibility of damage and system failure.
Knowing the Cost of Preventive Servicing
Many users hesitate to schedule regular servicing due to uncertainty around aircon servicing prices. However, preventive maintenance is far more cost-effective than paying for emergency repairs caused by water damage or compressor failure. In Singapore, the price for standard servicing ranges from $30 to $50 per unit. This depends on service type and number of units.
More comprehensive servicing, such as chemical wash or overhaul, may cost more but can resolve deeper issues causing leaks. Always ask for a breakdown of services included so you understand the value of each maintenance session.
Conclusion
An aircon leaking water is not just an inconvenience — it’s a sign that your unit needs immediate attention. Clogged drainage pipes, dirty filters, faulty drain pans, or low refrigerant can all lead to leakage. Regular air conditioning service is critical in preventing these problems and maintaining system performance. You can avoid costly deterioration and enjoy continuous cooling by understanding the causes and keeping up with maintenance.
