Should my aircon be leaking water?

It is normal for some water to be coming from your air conditioner when it is on, as long as it is coming from the drain tube outside and dries pretty fast once your air conditioner is off. The amount of water that is leaking from your AC's drain will depend on a range of factors though, including humidity, the temperature outside, and/or the temperature selected on your air conditioners thermostat.

If, however, water is leaking from the air outlet grille, or any other part of your unit inside (including dripping on your furniture) this is not normal and needs to be addressed.

Signs your aircon is leaking water

Besides the obvious, what other signs should you look out for when it comes to a leaky aircon?

  • Your ceiling has stain marks.
  • Your ceiling has bubbled paint.
  • There is damaged and/or broken plaster on your ceiling (this can include plaster caving in).
  • There are pools of water present.

Areas your aircon can be leaking

  • Water is leaking from the drain pipe connected to the outside unit: A small amount of water, when your air conditioner is on, is normal. Leakage when your unit isn't on can be a sign of a blocked drain pipe, causing it to build up instead of flowing through the drain.
  • Water is leaking from the inside unit: This can be caused from a range of things, from a drain line being disconnected to a condensation pump malfunctioning, so call in the professionals to help you out.
  • Water is leaking from the bottom of the outside unit: This can occur if you are using your aircon for heating, as opposed to cooling. Not usually a huge cause for alarm but keep an eye on it and call in a professional if you are in any way unsure.

Why is my aircon leaking water?

There is a range of reasons why your air conditioner may be leaking water.

Humid weather

If you are located in a region that has humid weather, condensation can pool from your aircon due to the difference in temperature. Remember, aircon's remove humidity from the air, so the more humidity, the more condensation from your system.

Filters and/or finned coil

When your air conditioning unit is on, the finned coil in the system stays moist and collects airborne dust particles easily. If there is a build-up of dust though, the finned coil may become clogged, which stops airflow and results in it being iced over .

Tip: If you are finding that more condensation then normal starts after you turn your ac off, this may be a sign of a blocked finned coil and a more serious problem.

Refrigerant gas levels

If the refrigerant gas levels in your ac system are too low, this means both the finned coil and condenser coil won't be able to create the 'cooling effect' they are required too. This can also cause the compressor to work with longer cycles, which can result in the finned coil ice-ing over .

Tip: If you are finding that your room isn't being cooled like it should, and there is less condensation, is a sign of a more serious issue.

Drain system

If your air conditioners' drain tray is blocked, or any of the pipes are clogged, this can cause leakage from your unit. Even if the drain tray is cracked or leaking, which may not be clear to you when looking at your system, this can still cause extra water to pool too.

Drain line

If the drain line of your ac unit has been disconnected, this can cause leakage.

Installation

If your aircon hasn't been installed correctly, or you have an incorrectly sized system (e.g. too small), this can cause extra water to be produced and cause leakage.
