Ceiling cassette aircon servicing
Panel-down servicing for ceiling cassettes. We pick general or chemical jet wash on arrival, based on what the coil actually needs. We’ll assess first, then confirm whether this is the right scope before you book.

What cassette servicing covers
Cassette servicing happens from below: the panel drops to expose the filter, coil, and drain pan, with no ceiling cutting and no patching after. We assess the coil on arrival, then match the level, a general clean or a chemical jet wash, to what it actually needs. Common situations where it fits:
Unit due for routine maintenance
General servicing every 3 to 6 months, depending on usage and room load.
Uneven cooling across the room
A dirty coil or misaligned vane chokes airflow in one or more directions.
Water dripping from the ceiling panel
Drain pan's likely blocked. Clear it before the leak worsens.
When cassette servicing isn't suitable
Servicing clears dirt and drainage. It won't fix mechanical or electrical faults.
Not cooling despite a clean coil
Likely a refrigerant or compressor issue, not a cleaning problem.
Error codes on the controller
Sensor, PCB, or communication fault. A clean won't resolve it.
Water leaking after servicing
Could be a cracked drain pan or disconnected line. That's a repair, not a blockage.
What you get
Outcomes match what the unit actually needed.
Airflow restored across all four directions
We clear the coil and blower so the cassette spreads air evenly again.
Drain pan cleared before it leaks
We address the usual cause of cassette ceiling water damage on every visit.
Vane alignment checked
Misdirected airflow gets caught and noted while the panel's down.
What we clean
We open the unit from below, look at the coil, then tell you which service level it needs.
Filter
We pull it from the panel, brush and vacuum it clear of dust, and refit.
Evaporator coil
Dry clean if buildup's light. Chemical jet wash if grime is compacted or mould has set in.
Drain pan
We flush it from the unit out to the discharge point. This is the usual source of cassette ceiling leaks.
Blower
Cleaned in place after disassembly. A chemical jet wash goes on only if the buildup calls for it.
4-way vanes
We check alignment and movement so airflow spreads evenly across the room.
Condition check
If we spot coil corrosion, drain pan cracks, or motor noise, we flag it separately. Nothing's added without approval.
Coil condition decides the service level. We tell you which on arrival, and nothing's added without your approval.
The panel comes down so the coil and drain pan can be seen before the cleaning level is chosen, and the drain pan is cleared every visit because it is the usual source of ceiling leaks. How a job runs, from first message to booking.
Workmanship warranty
30-day workmanship warranty. If a unit we serviced doesn't come up clean, or a problem traces back to our work, we come back and the labour is on us, with no charge for the return visit.
Cassette servicing case patterns
Real cleaning and diagnosis, not generic service claims. Open one if it looks familiar.
