Have you noticed a small drip in your air con? Or seen water underneath the indoor unit….or a damp patch on the wall or if it’s been going on for a while, a puddle on the floor? It’s easy to assume the air conditioner is simply getting old but a leaking air conditioner in Adelaide can have several different causes, and some are surprisingly simple to fix.

With Adelaide heading into warmer weather, it’s worth knowing what that water could be telling you before you switch the system on for another long summer.

7 common causes of your air conditioner leaking water

1. A blocked drain line

This is one of the more common reasons an air conditioner is leaking water. Your air conditioner naturally produces condensation while it is cooling the air and that moisture needs somewhere to go, usually through a drain line. If dust, dirt, algae or other debris builds up inside the drain, the water can back up and eventually overflow.

You may notice dripping from the indoor unit or water appearing around it. A professional air conditioning service in Adelaide can check the drainage system and clear a blockage safely.

2. A dirty air filter

Air filters are easy to forget. When a filter becomes heavily clogged with dust, airflow through the system can be restricted and in some cases, this can cause the indoor coil to become too cold and ice to form. Once that ice melts, there may be more water than the drainage system can handle. Regular filter cleaning is one of the simplest things you can do to help maintain your split system air conditioner.

3. Frozen evaporator coils

A frozen coil might seem like the opposite of a water leak, but the two can be connected. Restricted airflow, low refrigerant or an underlying mechanical issue can cause the evaporator coil to become excessively cold and freeze. When the ice eventually melts, water can spill where it shouldn’t.

If you can actually see ice forming on your air conditioner, it’s best not to keep running the system and hope it sorts itself out.

4. Low refrigerant

Refrigerants doesn’t normally disappear simply because an air conditioner has been running for years. If refrigerant levels are low, there may be a leak somewhere in the system. Low refrigerant can affect cooling performance and may also contribute to coil freezing and subsequent water leakage.

If your air conditioner is leaking water and not cooling properly, it is worth having the system checked rather than simply topping it up.

5. A damaged or poorly positioned drain pan

The drain pan collects condensation before it leaves through the drainage system. If the pan is cracked, damaged, rusted or incorrectly positioned, water may escape before it reaches the drain. This is something that usually requires a professional inspection.

6. Poor installation or drainage

Sometimes the problem isn’t the age of the air conditioner at all…if an indoor unit hasn’t been installed with the correct positioning or drainage fall, condensation may not flow away properly. This can eventually result in water finding its way back into the room.

For air conditioning installation Adelaide, correct drainage is just as important as choosing the right size and type of system.

7. The system simply needs a service

A dirty filter or restricted drainage and general dust buildup may not cause a noticeable problem but together they can affect how efficiently the system operates and for these small issues regular air con maintenance is all you need. A professional air conditioning service in Adelaide can check the system, drainage, filters, coils and other components to identify what’s actually happening.

Don’t ignore a leaking air conditioner

A small amount of water might not seem urgent, but repeated leaks can damage walls, flooring, paintwork and surrounding areas. And if the underlying problem is mechanical, continuing to run the system could make the issue worse.
