Air conditioners are vital for comfort in Singapore’s tropical climate, but they’re not without their problems. From water leaks to disturbing noises, malfunctioning units disrupt comfort and increase electricity bills. Knowing what causes these issues and how to troubleshoot them can help you restore your cooling system to optimal condition. Timely aircon troubleshooting in Singapore also helps avoid major breakdowns and expensive repairs.

Water Leaking from the Unit
When your aircon starts dripping water indoors, the issue typically lies in a blocked drainage system or faulty components. Drain pipes may become clogged with dust, dirt, or mould, preventing water from flowing properly. As a result, the condensation overflows. Another cause could be a damaged or rusted drain pan. If the leak persists despite filter cleaning, it’s best to request an aircon leaking service in Singapore to assess and clear the blockage or replace damaged parts.
Aircon Not Cooling Enough
If your aircon runs continuously but the room remains warm, there may be a refrigerant issue or sensor malfunction. Refrigerant leaks reduce the system’s cooling capacity and can affect the compressor. Dirty evaporator coils are another factor, as they hinder heat absorption. A technician can top up the refrigerant and inspect the coils. Cleaning them during scheduled aircon maintenance in Singapore also prevents future cooling inefficiencies and helps retain temperature consistency.
Bad Smells When Operating
Foul smells from your aircon are typically caused by bacterial growth in the drainage system or on the filters. A musty or sour smell is a sign of accumulated mould, which thrives in damp, dark conditions. In more severe cases, stagnant water inside the unit becomes a breeding ground for bacteria. Cleaning filters, drain pans, and coils can eliminate the odour. If it persists, professionals offering aircon cleaning in Singapore may need to disinfect the system thoroughly.
Loud or Unusual Noises
Air conditioners are not supposed to be loud. Clicking, rattling, or grinding sounds usually indicate internal damage. Loose parts, bent fan blades, or compressor issues can all lead to these noises. Ignoring them might result in more severe damage. Tightening screws or cleaning the fan area may solve minor cases, but for persistent or growing noise levels, it’s important to get professional aircon troubleshooting in Singapore to identify and repair the source properly.
Sudden System Shutdowns
A unit that shuts down shortly after turning on might be overheating or experiencing electrical issues. Overheating occurs when airflow is blocked or the system runs too long without a break. Faulty thermostats or power connections can also cause shutdowns. Regular aircon maintenance in Singapore includes checking wiring, ensuring sensors are calibrated, and verifying thermostat accuracy, all of which help prevent unexpected stops.
Ice Forming on the Coils
Frozen coils are a symptom of airflow restriction or low refrigerant. Dirty filters and fan issues limit air movement across the evaporator coil, causing moisture to freeze. This leads to reduced efficiency and potential water leaks once the ice melts. Turning off the unit and allowing it to defrost is a short-term fix. In the long term, having the coils cleaned and refrigerant levels checked during routine maintenance can prevent recurring freezing.
Weak or No Airflow
Weak airflow can make even the best air conditioner feel underpowered. This is usually the result of clogged air filters, dirty coils, or blower fan issues. Dust build-up restricts air circulation and forces the system to work harder, leading to higher energy consumption. Regular aircon cleaning in Singapore removes dust and debris, restores airflow, and improves indoor cooling. If airflow remains weak after cleaning, a deeper inspection may be required to check for faulty motors or ductwork problems.
Thermostat Issues
If your aircon is not responding to the thermostat or shows erratic behaviour, the sensor could be misaligned or damaged. The thermostat might also be positioned too close to a heat source, misreading room temperature. Resetting or relocating the sensor might solve the problem, but faulty components require replacement. Technicians skilled in aircon troubleshooting in Singapore can accurately diagnose thermostat issues and adjust or replace parts as needed.

Persistent Leaks After Basic Cleaning
When a unit continues to leak even after you’ve cleaned the filter and checked the drainage pipe, the problem may involve internal piping, faulty insulation, or corroded pans. Over time, regular wear compromises the internal water management system. Calling for an aircon leak repair in Singapore ensures a comprehensive assessment and long-term resolution, preventing water damage and mould growth in your space.

Routine Checks Make a Difference
A well-maintained aircon runs quietly, cools efficiently, and lasts longer. The problems listed above are minor issues that go unnoticed until they affect comfort and energy bills. Through routine inspections and cleaning, most of these faults can be detected early and resolved.
