You come home after a long day at work and go to put your air conditioner on to cool down your room… and it’s leaking. You are sure it wasn’t leaking water when you turned it on yesterday, and now a puddle is forming and you aren’t sure why. Is it broken? Does it need replacing or repairing? What should you do?
We all know how irritating a leaking aircon can be, so we have put together some information about dripping units, what you should do, and who you should call. Remember, this is a guide only and you should always call your local air conditioning specialist if you are unsure or the water is pooling around electrical wiring, this can be very dangerous, so get the experts in to help.
HOW DOES AN AIR CONDITIONER DEAL WITH EVAPORATION?
So, we have to start with the technical bit to ensure the rest makes sense. On a split system air conditioner, there is a drain from the head air conditioning unit that directs the water that is evaporating on the indoor unit coil to an external drain point. When an aircon is leaking, it is generally related to the drain component of the system not functioning effectively.
WHY IS MY AIRCON LEAKING WATER?
There are a few reasons why the indoor unit of an air conditioner can leak:
- The most common cause is a blockage in the drain from dust, dirt or mould.
- The drain can become disconnected from the head unit.
- The manufacturers drain may, over time, become brittle and crack.
- There may be dirt or other obstructions at the end of the drain. For example, the drain is in the garden and is blocked by a plant or debris.
- There was an installation error when the unit was first put in where there isn’t enough downward ‘fall’ on the head unit drain for the water being drained to flow properly.
- There is a failure of the drain pump. In some cases, a drain pump may be used in some aircon systems to help pump the water away in situations where there is no general ‘fall’.
