What happens if aircon trunking leaks in HDB?

Aircon Trunking

Air conditioners are a necessity in Singapore’s hot and humid climate, providing cooling comfort to both HDB flats and private residences. However, one common issue many homeowners face is aircon trunking leakage. Trunking refers to the plastic casing or duct that conceals the copper pipes, drainage pipes, and electrical cables connected to your air conditioning system. While it is designed to keep everything neat, safe, and functional, problems can arise when water begins to leak from the trunking.

At LetsCool Aircon and Services, we have seen many cases of trunking leaks in HDB flats. Understanding why this happens, the risks involved, and how to resolve it will help homeowners prevent costly damage and maintain a comfortable living environment.

Why Does Aircon Trunking Leak?

Several factors can cause aircon trunking in HDB flats to leak. The most common include:

1. Condensation Buildup

   When the insulation inside the trunking wears out or is poorly installed, condensation can occur on the copper pipes. Over time, this moisture seeps out, causing water leakage along the trunking line.

2. Clogged Drainage Pipes

   The drainage pipe is meant to carry away water produced during the cooling process. If the drainage pipe gets blocked with dirt, algae, or debris, the water can overflow and leak out through the trunking.

3. Improper Trunking Installation

   If trunking is not sealed properly or installed at the wrong angle, water may accumulate inside. Poor workmanship during installation is a common reason for leaks in HDB flats.

4. Aging or Damaged Insulation

   Insulation inside the trunking prevents condensation from forming. If it deteriorates with age, water droplets can form and drip out, creating visible leaks.

What Happens When Trunking Leaks in an HDB Flat?

Leaking trunking should never be ignored because it can lead to multiple issues that affect not only your home but also your neighbours. Here’s what can happen:

1. Damage to Walls and Ceilings

Water seeping from trunking can stain walls, bubble paint, or even cause plaster to weaken. Over time, this results in unsightly marks and structural damage to your HDB flat.

2. Electrical Hazards

Trunking also houses electrical cables that power the air conditioner. If water comes into contact with exposed wires, it can pose a serious safety hazard, such as short-circuiting or even fire risks.

3. Neighbour Complaints

In HDB flats, water from a leaking trunking may drip onto the unit below. This not only damages their walls and ceilings but can also strain neighbourly relationships if not addressed promptly.

4. Mould and Mildew Growth

Persistent moisture creates an ideal breeding ground for mould and mildew. This not only causes unpleasant odours but can also affect indoor air quality, potentially triggering allergies and respiratory issues.

5. Reduced Aircon Efficiency

If the root cause of the trunking leak is poor insulation or clogged drainage, your air conditioner may have to work harder to maintain cooling performance. This increases energy bills and shortens the lifespan of the unit.

How to Identify a Trunking Leak Early

As a homeowner, it’s important to spot early signs of trunking leakage before the problem worsens. Look out for:

• Water stains or wet patches along the trunking.

• Dripping sounds inside walls or near the aircon unit.

• Musty smell in the room caused by hidden moisture.

• Damp spots appearing on ceilings or walls.

• Complaints from neighbours below about water seepage.

If you notice any of these signs, it’s best to call a professional technician immediately.

What Should You Do If You Notice a Leak?

If you suspect or confirm that your aircon trunking is leaking in your HDB flat, here are the steps you should take:

1. Turn Off the Air Conditioner

   This prevents further water accumulation and reduces the risk of electrical hazards.

2. Check for Visible Blockages

   In some cases, leaks are due to blocked drainage pipes. However, attempting to fix it yourself without the right tools may worsen the situation.

3. Contact a Professional Aircon Service Company

   Experienced technicians, like those from LetsCool Aircon and Services, can accurately identify the root cause and carry out the proper repair, whether it’s replacing insulation, clearing drainage pipes, or re-installing faulty trunking.Daikin Aircon Servicing
