Aircon Trunking Leaking Water
Aircon trunking consists of the protective material that serves to conceal and protect wiring and pipework. However, it can leak aircon condensation for a variety of reasons, most of them preventable. Aircon trunking is mostly applicable to Singaporeans living in HDB flats because residents of condominiums and landed properties have the alternative of constructing a false ceiling for their aircon ductwork. But, all in all, this article is still useful for aircon users. It covers everything related to the issue of aircon trunking leaking water–the effects, causes, solutions, and preventive measures.
- Structural damage. Persistent leaks can cause water stains, peeling paint, and even damage to ceilings and walls.
- Mold and mildew growth. Damp conditions promote mold and mildew, which can affect indoor air quality and pose health risks.
- Electrical hazards. Leaking water near electrical wiring can create safety hazards, such as short circuits or electrical fires.
- Increased maintenance costs. Ignoring leaks can lead to more significant problems that require extensive repairs.

Clogged Drain Pipes
The most frequent cause of water leakage is a clogged drain pipe. In most aircon models, this is accompanied by a blinking light to indicate an error in the system. Dust, debris, and algae can accumulate over time, obstructing the flow of condensation water from the indoor unit to the external drainage point. When the aircon drain pipe is blocked, water backs up and escapes through the trunking. The presence of a faulty aircon water pump, if your air conditioning unit is equipped with one, can worsen the problem.
Poor Pipe Insulation
Refrigerant pipes transport cold gases, which can cause condensation to form on their surfaces. Without proper insulation, this condensation can drip into the trunking and leak out. Inadequate insulation is often the result of poor installation or deteriorating materials. To understand more fully how aircon gas and water piping work, as well as how pipe insulation plays a part in preventing leaks, consider reading our “Aircon Pipe Leaking” article.
Improper Installation
Substandard workmanship during aircon installation is another major factor. Issues such as poorly aligned trunking, loosely connected pipes, or insufficient sealing can create gaps where water accumulates and leaks.
Wear and Tear
Over time, components within the trunking may degrade due to frequent use, exposure to humidity, or aging materials. For instance, drain pipes can crack, and insulation foam can disintegrate, leading to leaks.
High Humidity Levels
Singapore’s humid climate exacerbates condensation issues. When the air is saturated with moisture, the air conditioning system generates more condensation, increasing the likelihood of leaks if the drainage system is not functioning optimally.
Overloaded Systems
Running an air conditioner beyond its capacity can produce excessive condensation, overwhelming the drainage system and causing water to spill into the trunking.
OUR TESTIMONIALS
Cleaning the Drain Pipe
A clogged drainpipe can be cleared using a vacuum pump or a high-pressure blower. A professional aircon servicing company can perform this task effectively and safely, ensuring the pipe is free of blockages.
Replacing Damaged Insulation
If poor insulation is the culprit, the affected foam should be replaced with high-quality insulation materials. This step prevents condensation from accumulating and dripping into the trunking.
Realigning the Trunking
In cases where improper installation is causing the leak, realigning the trunking and sealing gaps with silicone can prevent water from escaping. A qualified technician can perform this adjustment.
Repairing or Replacing Components
Cracked drain pipes or damaged trunking covers should be repaired or replaced to restore the system’s functionality. Additionally, consider using durable materials to ensure longevity.
Upgrading to a Larger System
If an overloaded air conditioner is producing excessive condensation, upgrading to a more suitable system may resolve the issue. Consulting an aircon specialist will help you determine the appropriate capacity for your HDB flat.
Engage a Professional Aircon Installer
Choosing a reliable and experienced installer ensures the aircon system is set up correctly. Proper alignment, adequate insulation, and tight sealing reduce the likelihood of leaks. Also, try to look for companies with a proven track record of addressing aircon trunking issues.
Commit To Regular Servicing
Scheduling regular aircon servicing—ideally every three to six months—helps keep the system in optimal condition. Professional technicians will clean the drain pipes, check for insulation issues, and inspect for signs of wear and tear.
Monitor Your Air Conditioning System Usage
Avoid overloading the air conditioner by using it within its recommended capacity. Setting the thermostat at an appropriate temperature and ensuring proper ventilation in the room can also reduce strain on the system. The NEA suggests a practical, energy-saving temperature setting of 25 degrees Celsius for an aircon.
Improve Ventilation
Enhancing ventilation in areas near the air conditioning unit can reduce humidity levels, minimizing condensation buildup, and subsequent leakage. Ventilation is important, especially for the outdoor unit. In fact, you can even cause the compressor to overload by not allowing adequate air flow around it.
Use Quality Materials
Investing in high-quality components, such as durable drain pipes and insulation foam, enhances the system’s reliability and minimizes maintenance needs. Active Plastics and Litaflex are popular aircon trunking brands in Singapore, and they have been known to be durable.
