Aircon repair in Singapore
Not cold, leaking, noisy or tripping: we’ll assess the fault first, then quote the repair.
Diagnostic visit: $30 / visit · VRV: $80 / visit. Visit fee waived if you proceed with the quoted work. Repair starts only after your approval.

The unit runs, but the room will not cool, cools slowly, or ices up.
Likely causes
- Blocked airflow or a dirty coil weakens cooling even while it runs.
- A refrigerant leak makes cooling fade over weeks; another top-up alone will not hold.
- Compressor or start faults leave airflow but little real cooling.
Water drips from the indoor unit, marks the wall, or wets the trunking.
Likely causes
- A drain choke backs water up until it overflows the tray.
- Poor drain fall or a cracked tray lets water escape the drain path.
- Leaks that return after servicing point to drainage, not gas.
The unit flashes, shows a code, or restarts with the same warning.
Likely causes
- A sensor reading out of range trips a protective code.
- Remote, receiver, or wiring faults can mimic a board failure.
- The control board is the last suspect, not the first.
The remote does nothing, or there is power at the wall but the unit stays dead.
Likely causes
- A failed capacitor or contactor can stop the unit starting.
- A control or wiring fault can block the start signal.
- A blown fuse or tripped safety can leave it unresponsive.
The breaker trips when the aircon runs, once or every time it starts.
Likely causes
- A shorting compressor or capacitor can trip the breaker.
- Water ingress or damaged wiring causes earth leakage.
- A shared or undersized circuit can trip under load.
Rattling, grinding, buzzing, or outdoor vibration that was not there before.
Likely causes
- Loose panels, worn bearings, or a failing fan motor change the sound.
- Outdoor vibration often traces to mounting, not the compressor.
The unit starts, runs briefly, then shuts off on its own, over and over.
Likely causes
- A faulty sensor or thermistor can misread temperature and cut early.
- Low gas or a dirty coil can trip a protection cut-out.
- A control-board or fan fault can stop a steady run.
You have a repair quote and want a second read before approving.
Likely causes
- Large part quotes like compressor or PCB deserve a check against the symptom.
- Repeated gas top-ups can signal a leak the quote skips.
Real work. Clear explanations.
“I really appreciate how honest and efficient this company is. They identified the problem quickly and fixed it without unnecessary charges. I would definitely recommend them!”
What we fix
Aircon repair spans the full range of faults, diagnosis first. The common paths, grouped by where the problem sits.
Cooling & refrigerant
Electrical & control
- Control board (PCB)
- Temperature sensors
- Capacitor
- Contactor & relay
- Aircon circuit & tripping
- Remote & IR receiver
Airflow & mechanical
- Blower & fan motor
- Swing & vane motor
- Bearing wear & noise
Drainage & water
- Drainage faults & leaks
- Drain pan & line
- Pipe insulation
If you cannot tell which it is, a diagnostic visit isolates the fault before anything is quoted.
Repair or replace?
A straight read on whether the unit is worth repairing. We confirm on-site, but here is how we weigh it.
Repair usually makes sense
- The unit is under about 7 years old.
- The fault is a lower-cost part: capacitor, sensor, drainage, or contactor.
- It cooled well right up until this fault.
- A fan motor or PCB on a 5 to 8 year old unit.
- The repair comes in well under the cost of a new install.
When to consider replacement
- The unit is 10+ years old and needs a compressor.
- Several parts have failed in the last year.
- Leaks keep returning despite repeated top-ups.
- The repair is creeping past half the cost of a new install.
- It is a discontinued model with hard-to-source parts.
If the unit is old or the numbers point to replacing it, see replacement options.
A technician finds the fault on site before anything is quoted: PCB, motors, sensors, capacitors, gas pressure, electrical and drainage. The diagnostic visit fee is waived if you go ahead with the repair. How a job runs, from first message to booking.
From our jobs
Photos our team took on jobs across Singapore.
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.
Repair case patterns
Diagnosis-led case notes, not generic service claims. Open the case if the symptom looks familiar.
