Why Air Conditioning Drips Indoors and What to Do about It

When your air conditioning’s outdoor side is dripping with water, then everything’s normal. Condensation is a sign that your unit is working to provide cold air, whether it’s a hot or cold day out. 

However, if it’s the indoor unit leaking water, it’s not something you should ignore. Unlike outdoor leaking, that’s not normal. Homeowners need to have an AC unit that works well during the summer wherever they are in Australia. If you see that your unit is leaking on the inside, the first thing you should do is turn the unit off and read this list of why it’s doing that and how you can handle it:

Reason 1: The Air Filter Is Dirty

When your air filter is dirty, it can restrict airflow to the evaporator coil. The coil can get too cold and freeze over if it lacks airflow. Once it melts, water will start dripping from the drain pan.

It’s essential to clean your air filter every three to six months.

Reason 2: A Clogged Condensate Drain

A blocked drain is the most common cause of water leaks from air conditioning. These drains can become blocked by the buildup of soil around the end of the drain outside, by a rodent climbing up the drain from outside, or by the drain hose becoming dislodged from the indoor unit. As a result, the water backs up and comes out of the indoor unit.

Fortunately, you can unclog it by ensuring the drain’s end is clear of soil. If there is a rodent stuck in your drain, you will have to cut the drain off above where the rodent is and replace it. If the drain hose has become dislodged, you can just reconnect it. You can also contact a professional to remove the blockage for you.

Reason 3: The Condensate Pump Isn’t Working Properly

If your air conditioning unit comes with a condensate pump, it will expel the water outside. If the pump stops working, water will come out of the front of the unit. You will need to have a professional check and replace the pump.

Reason 4: The Drain Pan Is Busted

The drain pan could be rusty if your air conditioner has been running for the past ten years. When it’s damaged, water can just fall right through the pan. The simplest solution is to replace it. 

Reason 5: Poor or Improper Installation

If you notice that the air conditioning is suddenly leaking, there was a problem with the installation. Contact the installers to come back and fix the issue so the system will continue working.

Reason 6: You’re Running Out of Refrigerant

The system will have low pressure if your air conditioning is low on refrigerant. This can cause the evaporator coil to freeze, just like a dirty air filter. Once it melts, water will overflow.

Another sign of a refrigerant leak is a bubbling or hissing sound. You may need to repair or replace the whole unit if you hear this.
