What's wrong with your aircon?
The unit runs, but the room won't cool. Or the air coming out is barely below room temperature.
Likely causes
- Blocked airflow can weaken cooling even when the unit is still running.
- Refrigerant leak can make cooling fade gradually over weeks.
- Compressor or start faults can leave you with wind but little real cooling.
Water drips from the indoor unit onto the wall, furniture, or floor. The source matters more than the drip itself.
Likely causes
- Drain-path blockage can cause steady indoor dripping.
- Coil freeze-thaw behavior can release water in bursts.
- Condensation or slope issues can produce hidden or recurring drips.
The air still comes out cool, but the volume is thin. Less push than before, or noticeably weaker at one of the units.
Likely causes
- A dirty filter or coil restricts the air path and makes the unit feel like it is blowing weakly from the moment it starts.
- An indoor fan motor or fan-speed control fault leaves airflow weak even after the filter is cleaned.
- Ice building on the coil starts with normal airflow that fades over the run.
The unit smells when it first kicks on. Musty, stale, or something worse.
Likely causes
- Damp buildup in tray or drain areas can create musty smell at startup or shutdown.
- Buildup on coil or fan surfaces can cause ongoing smell during runtime.
- Electrical heat odor can come from stressed wiring or relay contacts.
The remote does nothing. Or the unit beeps but won't start. Or there's power at the wall but the unit is dead.
Likely causes
- Power loss can prevent any startup response.
- A broken indoor-outdoor handshake can block startup even with standby power present.
- A protective lockout in board memory can stop startup despite signs of life.
The outdoor unit is louder than it used to be. Rattling, grinding, or a sound you haven't heard before.
Likely causes
- Loose mounting or vibration transfer can create rattling or humming noise.
- Fan motor or bearing wear can produce whining or grinding sounds.
- Compressor-side strain can cause heavy humming, buzzing, or banging.
The indicator light is blinking. Or the display is showing a code you don't recognise.
Likely causes
- Safety-trigger shutdown can cause repeated flashing cycles.
- Indoor-outdoor signal-link faults can trigger recurring error lights.
- Sensor/control faults can produce unstable blink patterns.
The unit starts, runs for a bit, then shuts off on its own — over and over, never settling into steady cooling.
Likely causes
- Heat overload can stop operation after a short runtime.
- Freeze-safety behavior can trigger repeated short cycles.
- Sensor or control instability can end cycles too early.
One room stays warm while the others cool fine. That unit runs, but the space never gets comfortable.
Likely causes
- A clogged filter or coil on the unit serving that room restricts airflow and reduces cooling output.
- The indoor unit for that room has a fault. Fan motor, thermistor, or PCB, while others remain unaffected.
- The room's heat load or airflow conditions differ significantly from the rest of the home.
The circuit breaker trips when the aircon runs. Once, or every time.
Likely causes
- An immediate trip on every restart usually points to a current leak or short.
- A trip after a brief hum usually points to startup overcurrent on a weak capacitor or stressed compressor.
- A burning smell or scorch mark with the trip points to heat damage at a terminal or board point.
Nothing broken?
Routine work, a new install, or just checking rates.

What customers say on Google
“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.”
How we solve your aircon problem
Describe your situation
Tell us what's happening: "not cold", "leaking", "breaker trips", and roughly when it started. A photo or short clip helps with leaks, error codes, or odd noises.
We assess and advise
We explain what the symptom points to, then recommend the next step: on-site diagnosis, servicing, repair, replacement, or monitoring if a visit can wait.
Confirm and book
When you're ready, we confirm the scope, timing, and address, then get you booked in the same chat.
Get the solution your aircon actually needs
A wash, repair, or replacement can all sound right from the symptom alone. We diagnose first, then match the work to the fault.
Service
The unit runs, but airflow, smell, or drainage points to cleaning.
Service
The unit runs, but airflow, smell, or drainage points to cleaning.
- Signs
- Weak airflow, a musty smell, slow drainage, or more than four months since the last wash.
- What happens
- Coil, blower wheel, and drain line cleaned so airflow and drainage come back.
Repair
A fault needs testing, or a failed part is worth fixing.
Repair
A fault needs testing, or a failed part is worth fixing.
- Signs
- Breaker trips, no power, ice on the pipe, abnormal noise, an error code, or a problem that keeps coming back.
- What happens
- We isolate the failed part, then fix or swap it — sensor, PCB, fan motor, gas, or compressor.
Replace
The system is old, or the repair no longer makes financial sense.
Replace
The system is old, or the repair no longer makes financial sense.
- Signs
- An 8+ year unit, an R22 system, repeated major repairs, or a quote nearing half the price of a new install.
- What happens
- Old unit out, a right-sized one in — only when a repair no longer pays off.
