Air conditioning plays an essential role in Singapore homes and offices, especially in the relentless humidity. While regular servicing ensures that your unit functions efficiently, leaks are an issue many people encounter. A leaking aircon might seem minor, but it can lead to bigger problems if not handled swiftly and professionally. Early treatments for the causes of these leaks can save you time, and money, and reduce further damage.
Faulty or Damaged Drain Pan
The drain pan is responsible for collecting condensation from the cooling coil. If it is rusted, cracked, or misaligned, water can seep out and damage surrounding areas. Older units are especially prone to corrosion, which compromises the integrity of the pan. A qualified aircon contractor can inspect the drain pan and replace it if necessary, ensuring that water is safely directed away from indoor surfaces.
Clogged or Dirty Drain Pipes
The common cause of leaking is drainage pipes that are blocked. Over time, algae can develop which can block condensation from the pipes. When this happens, water builds up and eventually overflows inside your property. This issue is particularly common in units that haven’t undergone scheduled maintenance. A professional aircon cleaning service can clear the blockage and restore the drainage system to proper function.
Frozen Evaporator Coils
Frozen coils might sound contradictory in a humid climate, but they can occur when airflow is restricted. Coils can freeze because of low fridge levels, dirty filters, and failing fans. As ice melts, too much water may flow into the drain pan. This can create leaks that appear suddenly and unexpectedly. Cleaning filters regularly helps, but when freezing continues, it’s time to bring in a technician for a more detailed inspection.
Improper Installation of the Unit
Leaks may also stem from poor installation practices. If the unit is not angled properly, water may accumulate and pour out. This risk is relevant to newer systems that have not been set up by experienced technicians. Proper aircon installation in Singapore requires careful attention to unit placement and the gradient of the drainage line. Engaging a professional air conditioning installation service from the outset can prevent this issue entirely.
Cracked or Loose Insulation
Insulation around the drainage line and pipes plays a key role in preventing condensation build-up. When this insulation is damaged or missing, the temperature difference can cause moisture to form and drip. This may look like a leak from the aircon unit, but the real culprit is the surrounding pipework. An aircon contractor can identify whether the insulation needs replacing or repositioning to stop recurring leaks.
Ageing Aircon Systems
All air conditioners have a lifespan. As internal components wear out and seals degrade, leaks become more likely. Older units may also experience more frequent breakdowns or need repeated repairs. At some point, replacing the system becomes more cost-effective than ongoing fixes. If you’re facing persistent issues, consider the costs of air conditioner installation in Singapore and weigh it against long-term repair bills.
Low Refrigerant Levels
While this issue affects cooling efficiency first, it can also lead to aircon leaks indirectly. A low refrigerant charge causes the evaporator coil to freeze, which, as mentioned earlier, leads to excess water when the ice melts. This condition also places additional strain on the compressor, leading to bigger mechanical issues. If your system struggles to cool and leaks are evident, it may be time to have refrigerant levels checked by a professional.
External Climate and Usage Habits
Singapore’s humidity increases condensation levels, especially in systems working overtime. When filters are left uncleaned, units run for long periods, or maintenance is skipped, the risk of leakage grows. Regular servicing and mindful usage can minimise the strain placed on the unit. Scheduling a periodic aircon cleaning service is a practical way to maintain system health and prevent moisture-related issues.

When to Call for Help
While wiping off a small drip may seem manageable, repeated leaks should not be ignored. If you notice water pooling around your aircon unit, smell mildew, or experience cooling inefficiencies, contact a certified aircon contractor. Fixing the issue without the right tools and knowledge could lead to further damage or safety hazards.For more information about aircon installation in Singapore, contact Newway Air Conditioning today.
