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.
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
Not sure which it is? An on-site inspection 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.
Old unit, or the numbers point to replacing? See replacement options.
How an aircon repair job works
No guesswork, no surprise bills. From your first message to a working aircon, here is what happens.
You message us
Tell us what is wrong: not cold, leaking, tripping, or an error code. We come back with a rough sense of the likely causes.
We assess on-site ($30)
A technician finds the fault for sure: PCB, motors, sensors, capacitors, gas pressure, electrical, and drainage. The $30 rules out work you do not need.
We explain what we found
Plain language: what failed, why it failed, and any connected issue worth knowing. No upsell scripts.
We quote, you decide
Exact parts and labour. If a part needs ordering, we give you the timeline. Nothing goes ahead without your say.
We repair and verify
The $30 comes off the repair, so you pay for the work only. We replace the part, run a full cycle, and confirm the fault is gone before we leave. The site is left clean.
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 labour warranty. If the same fault returns from the repair we did, we come back and the labour is on us, with no second diagnosis fee.
Parts
Parts follow whatever warranty the distributor sets for that component, so the term varies by part. We tell you the coverage before you approve the quote.
Documented repair cases
Real diagnosis work, not generic service claims. Open the case if the symptom looks familiar.
