Common problem
Air Conditioner Leaking Water in Salisbury Downs
A pool of water under the indoor unit, or a drip down the wall, almost always means a condensate problem rather than a refrigerant one. Salisbury Downs Air Conditioning finds the cause and fixes it, and we cover Salisbury Downs and the surrounding northern suburbs every week.
Water Where It Should Not Be
Water inside a split system is normal. The coil pulls moisture from your air, it collects in a tray, and a small line carries it outside.
The fault is when that water escapes somewhere else. Onto plaster, carpet, or a floor you walk on barefoot.
Most of the homes we attend here are single-storey brick veneer built through the 1970s and 1980s, so a ceiling drip from a ducted unit or a wall stain under a split head shows up quickly and is hard to ignore.
Catch it early and the fix is usually small.
Why Your Aircon Leaks Water
The causes are ordinary, and the cheapest ones are the most common. Here is what we find, in order of how often it turns out to be the problem:
Choked condensate line
Dirty filter or coil
Cracked or rusted tray
Dislodged unit or pipe
None of these get better on their own. A line that overflows once will overflow again, and each time it does, water sits where your house cannot handle it.
How it works
Checks You Can Safely Do
You can rule out the simple things before you call anyone. Turn the system off first, then:
-
Step 1: Step 1
Check the filter. If it is grey and matted, clean or replace it and run the unit again.
-
Step 2: Step 2
Look outside at the outlet. A steady drip while the unit runs is normal; nothing at all often means the line is choked upstream.
-
Step 3: Step 3
Check the head is sitting level on its bracket.
Leave everything else to us. Opening the casing, poking wire down a line or running the unit with the coil iced up tends to make the repair bigger, not smaller.
Do not wait on this
When a Leaking Air Conditioner Needs a Technician
Call straight away if water is dripping onto electrical fittings, or if the ceiling below a roof unit is bulging or stained. Those are damage-in-progress situations, not weekend jobs.
The same goes for a leak that appears during a heatwave. We hold ARC Licence L162586, the full refrigeration and air conditioning classification, so the work is done legally and properly.
We also move fast on urgent faults. Our Within-the-Hour Response applies where availability allows, and we answer emergency calls 24/7. A leak at nine at night is not something you should have to sleep next to.
How We Fix a Leaking Air Conditioner
Diagnosis comes first, because the fix depends on the cause:
- A choked line gets flushed clear and treated so the sludge does not rebuild.
- A split tray gets replaced.
- A frozen coil gets cleaned properly and checked for the airflow problem underneath it.
The price is settled first. You get Fixed Upfront Pricing before any work starts, so the figure on the quote is the figure you pay. No hourly rates, no bill shock at the end.
If the fault is our workmanship, our Lifetime Labour Warranty covers the return visit at no cost.
Some leaks are a symptom of a unit at the end of its life. If the tray, coil and line are all tired on a system past its second decade, we will say so honestly and quote a replacement rather than sell you repairs that buy a few months.
Why Older Salisbury Downs Homes Leak More
The suburb was built out fast as part of the City of Salisbury's northern expansion, and volume housing from that era sometimes carries condensate runs with marginal falls or non-standard fittings.
Add forty years of dust through the return air and those lines choke sooner than they should.
Ownership helps here. Most owners own their homes, so a proper fix beats a temporary one. We repair it once, with the right parts, and cleaning the system yearly keeps the line from silting up again.
Questions
Leaking Air Conditioner FAQs
Can I keep running my air conditioner while it leaks?
We advise switching it off at the wall, because running a unit with a choked condensate line can push water further into the ceiling or wall and turn a small job into a repair on plaster as well.
Why does the leak only show on hot days?
Heavy cooling pulls more moisture out of the air, so the condensate tray fills faster, and a line that copes on a mild day overflows once a heatwave has the system running flat out.
Is a leaking unit always a choked condensate line?
No, a choked line is the most common cause but a cracked tray, a rusted pan, a dirty filter freezing the coil or a unit that has shifted on its wall bracket can all put water where it should not be.
Do you quote before you start the work?
Yes, we diagnose the fault first and give you a fixed quote before any work starts, so you know the full cost up front with no hourly rates and no bill shock at the end.
