Top 3 leak causes

What our technicians solve daily

EZ Aircon
1

Clogged drainage pipe

Dirt and algae build up in the drainage line, backing up water into your fan coil.

2

Frozen evaporator coils

Low refrigerant gas or dirty filters block airflow, causing frost to melt rapidly.

3

Improper unit installation

Sloping gradient issues prevent gravity from moving condensation out smoothly.

Troubleshooting Guide

Common reasons your aircon breaks down

Most cooling and leaking troubles come down to four everyday issues you can spot early.

Clogged drainage pipe
Water leaking
Algae, dust, and jelly-like grime build up inside the drain pan and tube over time, preventing water runoff and causing leaks down your wall.
Signs: Water dripping onto flooring or wet stains behind the indoor unit.
Solution: Clear drain line with vacuum extraction and chemical flushing.
Dirty filter restricting airflow
Weak cooling
A thick blanket of dust blocks room air from reaching the cooling coils, forcing the motor to work harder while blowing warm or weak air.
Signs: Fan blowing quietly with little to no drop in room temperature.
Solution: Deep clean or replace antibacterial filters every 3 to 6 months.
Frozen evaporator coil
Ice buildup
Low refrigerant levels or blocked airflow causes the surface temperature of the indoor coils to plunge below freezing, creating thick ice layers.
Signs: Ice crystals forming on louvers and sudden water dripping when turned off.
Solution: Check refrigerant pressure and top up gas after sealing leaks.
Poor initial installation
Mechanical fault
Incorrect drainage gradient, improperly flared copper piping, or poorly mounted brackets lead to chronic leaks, strange vibrations, and gas leakage.
Signs: Loud rattling sounds, sudden gas loss, or recurring leaks after servicing.
Solution: Re-align slope, tighten fittings, and pressure-test joint connections.

Why Immediate Action Matters

What happens when you ignore an aircon leak

A small drip often hides a clogged drainage pipe, frozen coils, or corroded trays. Left untreated, water spreads quickly into your walls, electrical lines, and indoor air.

Structural Risk
Ceiling and wall damage
Water pooling behind the fan coil seeps directly into drywall, plaster, and concrete. Over time, this leads to yellowish ceiling stains, bubbled paint, and expensive carpentry repairs.
Estimated repair cost$300 – $1,200+
Health Hazard
Toxic mold and bacteria growth
Stagnant condensate trays become breeding grounds for black mold and mildew. As the blower wheel spins, it circulates harmful spores into your bedroom, triggering allergies and sinus flare-ups.
Onset time24 – 48 Hours
Urgent Danger
Electrical short circuits and fire risks
Drips running along internal wiring can reach the printed circuit board (PCB) or nearby power sockets. This causes sudden tripping of your main MCB breaker and poses severe electrical short dangers.
PCB replacement cost$180 – $450

Clear & Reliable Drainage

How we clear and repair aircon drainage

A step-by-step approach to eliminate water leaks, unclog condensate pipes, and protect your walls from moisture damage.

01

Detailed inspection

We examine your indoor fan coil unit, drainage tray, and piping routes to locate stagnant water, dirt accumulation, and overflow points.

Focus: Check water pan and pipe gradient
02

Root cause identification

Our technicians identify whether the leak is caused by jelly-like algae buildup, pipe sagging, incorrect slope, or damaged joint insulation.

Focus: Pinpoint blockage and pipe condition
03

Targeted repair & flush

We flush the drain pipe with high-pressure suction to extract sludge, re-align pipe gradients, and replace worn insulation or cracked fittings.

Focus: Vacuum clearing and pipe replacement
04

Drainage system testing

We run controlled water tests through the condensate line under active cooling to verify rapid, smooth discharge with zero secondary drips.

Focus: Live water flow and seal verification
