What drainage repair covers

Water from the indoor unit always looks the same, but the cause is one of four things: blocked drain, cracked pan, bad slope, or disconnected pipe. The fix depends on which one. We trace the full condensate path before quoting, so you're not paying for a flush when the pan needs replacing. Common situations where drainage repair fits:

Water dripping from the indoor unit
A blocked drain, cracked pan, poor slope, or loose pipe makes water back up and leak from the unit body.
Ceiling staining near the air outlet
Condensate's overflowing or escaping before it reaches the discharge point.
Leak returns after servicing
A drain flush clears a simple blockage. It won't fix a cracked pan, bad gradient, or misaligned pipe.

When drainage repair isn't suitable

Not all water near an aircon unit starts with drainage repair.

Condensation on the unit body
Usually points to insulation, airflow, or installation conditions, not a drain fault.
Ice melts and drips from the indoor unit
Start with cooling diagnosis. Refrigerant or airflow problems freeze the coil first.
Water appears only around the outdoor unit
Some outdoor condensation during cooling is normal. Book a diagnostic visit if the source isn't clear.

What you get

Stop the leak by fixing the cause, not just clearing what's visible.

Full drainage path checked
We assess pan, pipe, slope, and discharge point before confirming the repair.
Cause-specific repair
Blockage, pan damage, slope issue, or disconnected pipe each get the right fix.
Leak verification
We test the unit after the work, so slow drainage, pooling, or repeat dripping gets caught before handover.

What we check before repair

We trace the full condensate path before deciding between clearing, pan replacement, slope correction, or pipe rerouting.

Drain pan condition
We check whether water's collecting correctly or escaping through a cracked, shifted, or overflowing pan.
Drain line flow
We check the line for dust, algae, slime, and partial blockage that slows drainage before it fully backs up.
Slope and routing
Condensate needs gravity fall. We check for reverse gradients, sagging runs, loose joints, and discharge issues.
Water test
Once the repair's done, we run water through the full route to confirm flow from pan to discharge.

We trace the whole condensate path, pan, line, slope and discharge, so a flush is not sold when the pan needs replacing, and we run water through the full route before we leave. How a job runs, from first message to booking.

Brand-specific drain pump repair

Each brand page lists the models we see, that brand’s fault codes, parts lead times and when replacement makes more sense.

Workmanship warranty

We stand behind the repair we carry out, and we are straight about the part of the cover we do not set ourselves.

Labour

30-day workmanship warranty. If the same fault returns from our repair, we come back and the labour is on us, with no second diagnostic visit fee.

Parts

Parts carry the distributor's warranty for that component, so the term varies by part. We tell you both terms before you approve the work.

Drainage case patterns

Diagnosis-led case notes, not generic service claims. Open the case if the symptom looks familiar.

Frequently asked questions about aircon drainage repair in Singapore

How much does drainage repair cost?

A simple drain clearing is straightforward. Pan replacement, slope correction, or pipe rerouting takes more labour and materials. We diagnose first, then quote. The $30 visit is waived if you proceed.

Can a regular servicing fix a drainage leak?

If it's a minor blockage, yes, the drain flush in general servicing usually clears it. If it's a cracked pan, wrong slope, or misaligned pipe, servicing won't fix it. That needs targeted drainage repair.

Why does my aircon keep leaking after servicing?

If the leak returns after servicing, it isn't a simple blockage. It's usually a gradient issue, a cracked pan, or a poorly routed drain line. We trace the full path to find and fix the underlying cause.

Is aircon water leaking dangerous?

Not immediately, but left alone it damages walls and ceilings, encourages mould, and in rare cases water near electrical connections becomes a safety issue. Best to fix it promptly.
