What Water Leaking From Your Aircon Means
Water dripping from the indoor head or pooling on the floor almost always means the condensate drain, drip tray, or coil is not doing its job properly. Coombabah's humid, wetland-adjacent air makes this common. Our ARC-certified technicians (ARC #L160535) find the cause and clear it properly.
Common Causes of an Aircon Leaking Water in Coombabah Homes
A blocked or algae-filled drain line
The most common cause. Warm, humid air near Coombabah Lake feeds algae and slime in the condensate line, so it blocks and backs up water into the unit or onto the wall.
A dirty filter causing the coil to ice up
A choked filter starves airflow, the coil freezes, and when it thaws the tray cannot cope with the sudden meltwater, sending it dripping through the ceiling or down the wall.
A full or cracked drip tray
Over time the tray under the indoor unit can crack, corrode, or simply fill faster than it drains, especially in older units common in Coombabah's 1980s and 1990s housing stock.
Poor drain line fall from the original install
If the drain pipe was not installed with enough downward fall, water sits in the line rather than draining away, and it eventually overflows back into the room.
Salt-laden air corroding fittings near the waterways
Homes closer to Coombabah Creek and the Broadwater see faster corrosion of drain fittings and trays, which can crack seals and let water escape where it should not.
Is a Leaking Aircon Urgent?
A slow drip is not an emergency, but ignoring it risks ceiling and wall damage, so it is worth acting on promptly. You can check the filter yourself; clearing the drain line properly is a technician's job.
- You can safely check and clean the filter and see if dripping slows
- Clearing the drain line and inspecting the tray properly needs a technician, not a DIY attempt
- Water staining a ceiling or wall should be looked at within a day or two, not left for weeks
- A steady drip during a heatwave, when the unit runs constantly, needs prompt attention
What To Check Right Now
A couple of quick, safe checks can tell you whether this is simple or needs a technician:
- Turn the unit off and check the filter, a choked filter is a common trigger for ice-then-melt leaks.
- Look for visible pooling under the indoor unit and place a towel to protect flooring.
- Check the outdoor unit's drain point is not blocked by leaves or garden debris.
- Note whether the leak started after a hot, humid run or during light rain.
- Call an ARC-certified technician (Lic #83326, ARC #L160535) if dripping continues.
When To Call an Aircon Technician for a Water Leak in Coombabah
- Water is running down the wall, staining the ceiling, or pooling on the floor
- The drip continues after a filter clean and a day of normal use
- The indoor unit smells musty alongside the leak
- The leak started suddenly after the unit iced up and then thawed
- You cannot see or reach the drain line to check it yourself
Any of these means it is time to call rather than keep mopping up. We respond same-day where availability allows, with clear pricing before we start. See our air conditioning repairs and air conditioning cleaning.

How We Fix an Aircon Water Leak in Coombabah
Fault Finding
We trace the water back to its source, whether that is the drain line, the tray, the coil, or the original install fall, before touching anything.

Once we know the cause, we explain it in plain terms and give you clear pricing before we start, with any options laid out on site.

We run the system, confirm water is draining correctly, and check for any further pooling before we call the job done.
Why This Is Common in Coombabah Homes
The humidity off Coombabah Lake and the surrounding wetlands feeds algae growth in drain lines faster than drier suburbs, and many homes still run original 1980s-90s drain fittings. Nearby Arundel sees the same pattern.

Common questions
Air Conditioner Leaking Water FAQs
Real questions homeowners ask when their aircon starts dripping water.
Why is water leaking from my air conditioner?
Almost always a blocked or algae-filled drain line, a dirty filter causing the coil to ice up and then melt, or a full drip tray that has nowhere for the water to go.
What causes an air conditioner to drip water inside?
A blocked condensate drain, a frozen coil that thaws and overflows, a poor install fall on the drain line, or a cracked or full drip tray under the indoor unit.
Can I fix an aircon water leak myself?
You can safely check and clean the filter, but clearing the drain line and inspecting the drain pan properly is a job for a technician to avoid water damage returning.
Do I need a technician to fix a leaking air conditioner?
If water keeps returning after you have checked the filter, yes, the drain line or tray needs a proper inspection and clean by a technician.
How much does it cost to fix an air conditioner leaking water?
It depends on whether it is a drain clean, a tray repair, or an install fall issue. We give clear pricing before we start, with options explained on site.
Does coastal humidity cause more aircon drain blockages in Coombabah?
Yes, the humid air off Coombabah Lake and the surrounding wetlands feeds algae growth in condensate drains faster than in drier inland suburbs, leading to more frequent blockages.
