Common problem
Air Conditioner Leaking Water in Mile End
Water pooling under an air conditioner is a fault we fix across Mile End every summer. Mile End Air Conditioning traces the leak to the cause, then quotes the price before any work starts.
Mile End homes run their cooling hard through dry Adelaide summers, and a leaking unit rarely fixes itself. The good news: most causes are simple, and most repairs are small once the fault is found.

Why Mile End Households Call Us For Aircon Water Leaks
A drip from an indoor unit usually means the system cannot get rid of the water it pulls from the air. Our crew is local, family-owned and available around the clock, so a leak on a hot afternoon does not have to wait until Monday.
In detail
Why Your Aircon Leaks Water
Condensation is the short answer. Every cooling unit pulls moisture from warm indoor air, and that water has to drain away cleanly. When something blocks that path, the water goes where you can see it.
The causes below run from cheapest to costliest, in the order we find them.
Choked Condensate Line
Dust, mould sludge and insect nests sit in the condensate line until water backs up. This is the most common cause we see, and a flush usually fixes it on the spot.
Dirty Filter And Coil
A choked filter lets the coil ice over, then the melt water overflows the tray. Homes a street back from South Road collect dust faster, so this shows up sooner there.
Corroded Drain Pan
Older ducted systems, especially in cottages and semi-detached pairs built before 1940, can carry a tray that has corroded through after decades in a hot roof space. The pan needs replacing, not patching.
Bad Installation Tilt
An indoor unit must sit level or slightly angled toward the outlet. If a previous installer got that wrong, water spills off the wrong edge every time the system runs long.

Checks You Can Safely Do Yourself
Two minutes of looking can save a callout, and it helps us diagnose faster if you do call. Keep it to these:
Switch the system off
Check the filter
Look at the outlet outside
Note where the water appears
Leave the roof space, the condensate line inside the wall, and anything refrigerant-related to us. That is licensed work.
Checklist
When A Leaking Split System Needs A Professional
Some leaks are call-now jobs, not wait-and-see jobs. Ring us when any of these apply:
- Water is dripping onto or near electrical fittings
- A ceiling stain is spreading below the unit
- The leak returns after you have cleaned the filter
- The leak comes with weak airflow or ice on the pipes
Water damage through a plaster ceiling costs far more than the repair that prevents it. We hold ARC Licence L162586, RAC01 - Full Refrigeration and Air Conditioning Licence, so the refrigerant side is covered properly, and we will diagnose the deeper fault honestly.
How it works
How We Fix Air Conditioner Water Leaks
Every leak gets the same straightforward treatment, and you know the cost before we start.
- 01
Trace The Source
We test the unit running, check the tray, the fall on the condensate line and the coil, and find where the water is actually escaping rather than guessing from the wet patch.
- 02
Fixed Quote First
You get the price in writing under our Fixed Upfront Pricing promise before any repair begins. No hourly rates, no bill shock at the end.
- 03
Repair And Flush
We clear or replace the faulty part, flush the condensate line, and confirm the water flows freely outside before we pack up.
- 04
Backed By The Warranty
If a fault later comes back to our workmanship, the Lifetime Labour Warranty means we return and fix it at no cost. That is the deal, in writing.
In detail
Why A Small Leak Deserves A Fast Fix
Water finds its own path. A drip that starts as a nuisance can soak insulation, stain ceilings and, in the older cottages through the original grid, sit inside solid masonry walls where damage stays hidden for months.
Electrical risk is the other reason. Water and switchboards in roof spaces are a bad combination.
Sorted early, most leaks are a one-visit job. Left alone, they become a plasterer's job too.
What you get
Aircon Leak Repairs Done Properly
A leak is rarely just a leak. It is a symptom of drainage, airflow or installation that needs a proper look, and that is what we do.

Air Conditioner Leaking Water FAQs
Is it safe to run an air conditioner that is leaking water?
Switch it off, because water near electrical parts and a dripping unit through a ceiling both get worse the longer it runs, and a technician can usually sort the cause quickly once you call.
Why does my aircon leak more on hot days?
A unit working flat out through a 38-degree day pulls far more moisture out of the air, so a partly blocked condensate line that coped in mild weather overflows once the cooling load peaks.
Can a leaking unit mean the system needs replacing?
Usually not, because most leaks trace back to a condensate line, filter or coil problem, though we test the whole system honestly and tell you if replacement is the better spend.
How do I stop it leaking again next summer?
Book a professional clean every twelve months, ideally in spring, because a service flushes the condensate line and clears the filters and coil that cause most overflows in the first place.
