In detail
Split System and Ducted Leaks, Cheapest Cause First
A leaking unit almost always comes down to water that should have drained away but could not. Work through the causes in order and the cheapest fix usually wins.
Blocked condensate drain
Dust, mould sludge and even insect nests block the drain line over time. Water backs up in the tray and spills from the indoor unit. It is the most common cause we see and usually a straightforward repair.
Choked filter or coil
A blocked filter starves the coil of airflow, the coil ices up, and the melt water overflows the tray. This is common in the 1970s brick homes around Kestral Way, where systems have run hard for years without a service. A clean often fixes it outright.
Drain with no fall
Condensate drains rely on gravity, and this suburb sits on the foothill slopes where every fall matters. A pipe that has sagged or shifted holds water instead of shedding it, and the tray overflows on long run days.
Rusted or cracked tray
Older units can rust through the tray itself, so water escapes before it ever reaches the drain. If the pan is gone on a system of that age, we will tell you honestly whether repair or air conditioning replacement makes more sense.
Low refrigerant
Low charge makes the coil freeze and then drip as it thaws. It also means the system is working harder than it should, so it needs a proper test rather than a top-up and hope.

Safe Checks Before You Call for Aircon Repairs
There are a few things worth checking before you book anyone. None of them involve opening the unit or working at height.
Check the filter
Look at where the water appears
Turn the system off
Check the drain outlet outside
If the filter was clean and the water keeps coming, stop there. The next steps need a technician with the right tools and licence.
Do not wait on this
When a Water Leak Needs Urgent Air Conditioning Repairs
Some leaks can wait a day. Others cannot. Call us straight away if any of these apply:
- Water is dripping onto a power point, light fitting or electrical appliance
- The ceiling below the unit is bulging, stained or wet
- The system has iced over and is still running
- It is a heatwave day and the house has no working cooling
We hold 24/7 emergency availability, and urgent issues get our Within-the-Hour Response where availability allows. A leak onto plaster or wiring only gets worse while you wait.
How it works
How We Fix a Leaking Cooling System
The diagnosis comes first, because guessing at a leak wastes your money.
- 01
Find the water path
A technician traces the condensate from tray to outlet, checks the fall along the pipe and tests the flow. On sloping blocks, a pipe that has shifted is a regular culprit, so we check the run properly rather than just flushing it blind.
- 02
Clear, repair or re-pipe
Choked lines get flushed and treated so the sludge does not return next summer. Sagging or cracked sections get re-supported or replaced. If the tray is rusted through, we quote the honest fix.
- 03
Test and clean up
We run the system through a full cycle, confirm water is leaving the property the way it should, and leave the work area clean. Every refrigerant job is carried out under ARC Licence L162586, a full refrigeration and air conditioning licence.
Good to know
Leaking Water Questions From Local Households
Is it safe to keep running a leaking air conditioner?
Usually not, because the water can reach electrical parts, stain ceilings and feed mould in the roof space. Turn the system off at the wall and call us for a diagnosis.
Why does my air conditioner leak more when it has run all day?
Long running hours produce more condensate, so a line that was coping on short cycles gets overwhelmed and overflows. A choked condensate pipe or a sagging run is usually the cause.
Can a dirty filter really cause water inside the house?
Yes. A choked filter starves the coil of air, the coil ices over, and the melt water ends up dripping from the indoor unit instead of draining away cleanly.
How much does it cost to fix a leaking air conditioner?
It depends on the cause, which is why we diagnose first and give you a fixed quote before any work starts. No hourly rates, no bill shock, and the price holds.
