Servicing
For dirt, buildup, and skipped maintenance.
General service, chemical wash, or chemical overhaul — chosen after we see the coils.

Same Symptom, Different Problem
Pick the closest match to understand what’s likely going on.
The most common complaint we get. The unit is running but the room won't cool — or it's blowing air that's barely below room temperature.
- 1.Blocked airflow can weaken cooling even when the unit is still running.
- 2.Refrigerant leak can make cooling fade gradually over weeks.
- 3.Compressor or start faults can leave you with wind but little real cooling.
- 4.High room heat load can outpace the unit's capacity even when everything works.
That's why we check gas pressure, coil condition, and compressor health before recommending anything.
How We Resolve It
Cleaning, repair, or replacement — the finding decides which. Same assessment either way.
Repair
When a specific part has failed — capacitor, fan motor, PCB, thermistor, drain.
We test on-site, replace the component, and confirm the fix.
Replacement
When age, repeat faults, or damage make repair uneconomical.
We size the replacement to your room, then quote the full job.
A Few Things to Note
If any of these apply, they're worth acting on before you reach out.
Breaker keeps tripping
Don't keep resetting it. Whatever caused the trip is still there, and each reset stresses the compressor and the breaker further. Switch off at the isolator and let us know.
Water is dripping from the unit
Switch it off first. A running unit keeps pulling in humid air and adding to the drip — turning it off buys time without making anything worse.
Error code or blinking light
Note the sequence — how many blinks, which light, or the code on the display. This tells us which sensor or circuit flagged the fault before we arrive.
Gas was topped up before
Let us know if a leak check was done. Refrigerant is sealed; if it dropped once, there is a physical leak, and the timeline tells us how severe.
Had it serviced but problems came back
Let us know what was done and when. If the same symptom returned within weeks, the root cause likely wasn't found — not that the service was poor. The history helps us pick up where the last visit left off.
SAFETY WARNING
If you smell burning, see sparks, or hear loud electrical buzzing — switch off at the isolator and don't run the unit again until it's been checked. These are not symptoms to diagnose remotely.

What Clients Say
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!

Matthew Lim
Accurate diagnosis for electronic problem, fair price for recond parts instead of expensive new parts, otherwise may just need to replace the whole aircon unit.

Great people and process. Booked their $30 check when my aircon could not switch on. They traced the problem to wiring. No upsell, no drama. Repair done same day, check fee waived. Everything upfront, no hidden cost.
