Common problem
Air Conditioner Leaking Water in Blackwood
Water dripping from an indoor air conditioning unit is a fault we fix across Blackwood every summer. The drip itself is rarely urgent, but the damage it leaves on plaster and floorboards grows every hour you leave it running.
Why Your Air Conditioner Leaks Water
An air conditioner pulls moisture out of the air, and that water drains away through a small pipe. When anything blocks, rusts or shifts along that path, the water has nowhere to go except your floor. Here are the causes we find most, cheapest first.
Blocked condensate drain
Dust, mould sludge and insects pack into the drain line until it chokes. A flush clears it, and it is the most common and least expensive fix on our list.
Dirty air filter
A clogged filter freezes the coil over time, and the melt later floods the drain pan. Check the filter first, because this one costs you nothing but five minutes.
Rusted drain pan
Older units develop cracked or corroded pans that let water straight through. Many homes around Blackwood Railway Station still run original-era systems, and those pans are often the culprit.
Drain not sloped
Water only drains when the pipe falls consistently toward the outlet. On the foothills blocks here, where houses sit on sloping cuttings and the ground itself moves, a drain that was set right years ago can lose its fall and start pooling.
Safe Checks Before You Call
A few checks cost nothing and rule out the simple causes. Turn the system off at the wall first, because a wet unit and live power do not mix.
Check the filter
Look at the drain outlet
Check the controller
Anything past the filter is refrigerant, drainage or electrical work, and that needs a licensed technician. You can safely check the filter and settings, but leave the internals alone.
Do not wait on this
When a Water Leak Needs a Technician
Call us the same day if water is reaching electrical fittings, spreading across timber floors or staining the ceiling below a roof-mounted unit.
- Water near power Dripping onto power points or electrical fittings is a stop-and-call situation, not a watch-and-wait one.
- Timber and plaster Hills houses around the gullies often have older plaster and timber finishes that soak water up fast, so waiting a week turns a drain flush into a repair bill.
If the leak comes with weak cooling, it may be a frozen coil rather than a simple blockage, and that fault is covered on our air conditioner not cooling page.

Questions
Your Aircon Water Leak Questions
Is water leaking from my air conditioner an emergency?
It can wait a day unless water is reaching wiring, plaster or floorboards, because damage grows every hour it runs, and we hold ARC Licence L162586 to fix it properly.
Why does my air conditioner leak more on hot days?
A unit pulling hard through a heatwave produces far more condensate, so a drain that copes on mild days overflows once Blackwood hits a run of days over 40.
Can a leaking indoor unit damage my house?
Yes, because water soaks plaster, skirtings and floorboards long before the stain shows, and older hills homes with timber finishes wear that damage badly.
How much does it cost to fix a leaking air conditioner?
We quote Fixed Upfront Pricing before any work starts, so you know the full figure for the drain flush or pan repair before we lift a tool.
