Aircon Water Leakage Unraveling the Mystery of AC Water Issues in Singapore

Exploring the Enigma of Air Conditioning: Deciphering the Intricacies of Water Leakage

Encountering the perplexing issue of water leakage from air conditioning units is a daily tribulation faced by approximately 200-300 residents in Singapore. This unforeseen challenge not only introduces discomfort but also poses threats to property and elevates energy bills. Within this discourse, we shall delve into the myriad factors contributing to aircon water leakage, presenting pragmatic remedies to ensure the seamless operation of your cooling system. 

Additionally, we will scrutinize pertinent case studies, offering insights into the dos and don’ts of air conditioning maintenance.

The Origin of the Drip: Unraveling the Condensation Conundrum

Within the confines of your air conditioning unit’s indoor apparatus lies a crucial component known as the evaporator coils. These coils play a pivotal role in cooling the ambient air. As warm air encounters the frigid condenser, the condensation process initiates, birthing water droplets. These droplets gracefully cascade into a drainage pan, an essential component facilitating the channeling of water through a drainage pipe leading either outdoors or into your bathroom.

Discovering the Frontal Water Ballet

Unraveling the enigma of air conditioning water leakage leads us to identify ten recurrent reasons for this conundrum:

Obstructed Drainage Line

The foremost culprit in air conditioner water leakage. A congested drainage line leads to water accumulation, potentially causing overflow from the drain pan. Periodic monitoring and cleansing of drainage lines are imperative to avert this issue. Maintenance rituals involving a water and bleach mixture assist in preventing clogs.

Excessive Accumulation of Dust and Debris

The buildup of detritus on the evaporator coil acts as insulation, impeding efficient heat exchange and triggering freezing, culminating in water leakage. Regular aircon servicing is indispensable to maintain a pristine evaporator coil.

Impaired or Detached Drain Pan

The drainage pan beneath the evaporator coil, designed to capture condensation, may lead to water overflow and leakage if obstructed or improperly connected.

Clogged or Soiled Air Filters

Surprisingly, dirt-clogged air filters induce extreme coldness retention within the unit, resulting in ice formation and eventual water dripping onto the floor.

Refrigerant Leaks

A refrigerant leak in the AC unit can induce freezing of the evaporator coil, prompting water leakage.

Malfunctioning Condensate Pump

In certain AC units, a defective condensate pump can impede water removal from the drain pan, causing leakage.

Deteriorated Components

Over time, components like gaskets, seals, and hoses in the air conditioning system may degrade, leading to leaks.

Incorrect Installation

Inaccurate installation can spawn various aircon maladies, including water leakage. Ensuring a correctly configured drainage system is pivotal for efficient water expulsion.

Humidity and Elevated Temperatures

Singapore’s humidity levels pose a challenge for air conditioning units. High humidity impedes efficient moisture extraction, resulting in increased condensation and water leakage. Combating this requires considering a dehumidifier in tandem with your air conditioner.

Neglecting Regular Maintenance

Routine maintenance, orchestrated by a professional HVAC technician in Singapore, is indispensable for averting aircon water leakage. Annual inspections can preemptively identify and address potential issues.

Remedial Measures and the Financial Implication

To remedy A/C water leaks, consider the following solutions and associated costs:

Chemical Flushing of Drainage System

Addressing clogged drainage lines through a chemical flushing process, dissolving accumulated debris. Cost: Approximately $80, with attractive discounts available when booked through our platform.

Realigning the Drainage Tray or Drain Pan

Correcting the positioning of the drainage tray in indoor aircon units to prevent water leakage. No additional cost.

Drain Pan Replacement

Complete replacement of a damaged drain pan. Cost: Around $80 to $120, contingent on the brand, inclusive of supply, transport, and labor.

Chemical Wash and Chemical Overhaul

Conducting a chemical wash or overhaul to address debris, dirt, and mold accumulation, preventing ice formation and subsequent water leakage. Costs vary; details are available here.

Resolving Enigmatic Cases: Unraveling the Mysteries of Aircon Water Leakage

Case 1 – Installation Alignment Anomaly

Mr. Zac’s recurring water leakage predicament post-new aircon installation prompted a meticulous examination. Past records revealed a misaligned drainage system, causing water from the evaporator coil to flow in reverse. Correcting the alignment resolved the issue.

Case 2 – Swift Resolution to Frontal Water Woes

Stella’s aircon leak, reported at 3 am, initially proposed an expensive chemical overhaul solution by another service provider. A prompt 9 am service slot dispatched a technician who identified a choked drainage pipe. A cost-effective chemical flushing swiftly resolved the problem.


Embarking on a chemical overhaul may not always be the panacea for aircon water leakage. Rigorous troubleshooting is imperative to discern the root cause. For heavy air conditioning users, an annual Chemical Overhaul is advisable to forestall water leakage issues.
