Air Conditioner Leaking or Dripping Water? Here’s a Simple Fix (90% of Cases Solved)
If your air conditioner is leaking or dripping water, it’s usually not a major issue.In many cases, the cause is a blocked drain pipe — something we commonly see in rental properties across Brisbane, including areas like Darra and surrounding suburbs
1. Common Cause: Blocked Drain Pipe
Air conditioners remove moisture from the air, and that water flows out through a drain pipe.
Over time, dust and debris can build up inside the pipe, causing water to back up and leak from the indoor unit.
2. A Simple Way to Fix It
In many situations, the issue can be resolved with a simple flush:
- Turn off the air conditioner
- Take a water bottle
- Slowly pour water into the drain pan (indoor unit)
- Check the outdoor unit to see if water flows out
If the water flows through, the blockage is usually cleared and the dripping stops.


3. If It Doesn’t Work
If the water doesn’t drain, the pipe may be fully blocked, and a technician may be required to clear it using a vacuum or compressed air.
If water drains but the unit is still leaking, it could be related to low refrigerant gas, which will also require professional inspection.
4. How We Handle This
When a tenant reports water dripping, we don’t immediately arrange a technician.
Where possible, we attend the property first, check the issue, and carry out the simple fix above using the water bottle method.
In many cases, this resolves the problem on the spot,
without the need for unnecessary call-out costs.
For example, we recently attended a property in Darra where a tenant reported a leaking air conditioner.
After a quick inspection and flushing the drain, the blockage cleared and the issue was resolved immediately — no technician required.
If further work is required, we then arrange the appropriate professional.
Final Thoughts
Water dripping from an air conditioner is often caused by a minor blockage and can usually be resolved quickly.
A practical, hands-on approach helps ensure the issue is fixed efficiently while keeping maintenance costs under control.
