Portable Aircon Is Leaking Water – Top 7 Causes

Here are seven common reasons why your portable aircon is leaking water.

1. Clogged Drain Hose

The drain hose is responsible for moving the condensation out of the system. If the drain hose becomes clogged with dirt or debris, the water can go back into the unit and leak from somewhere inside it.

To fix this issue, ensure the drain is clean and free of blockages. You can also detach the drain to clean it properly. 

2. Full Drain Pan

A full or malfunctioning drain pan can be the reason why the portable AC is leaking water. Most aircon units have drain pans that accumulate condensation and let the water flow steadily through the drain pipe.

The water can start leaking if there is any problem with the drain pan or it is full. Make sure that you empty the drain pan regularly. If the pan is cracked anywhere, repair the crack, as water can leak from it to the outside.

3. Dirty Or Blocked Air Filters

Dirty or clogged air filters can be a reason why portable air conditioners are leaking water. Dirty filters cause air trapping within the aircon. Air can’t properly circulate through blocked air filters.

In this case, the evaporator coil can freeze up. When the ice on the coils melts, water can leak from the unit. Make sure to clean the filter once every month to prevent any air trapping. 

4. Improper Positioning 

Imperfectly aligned aircon or those with a slight tilt can leak water due to improper positioning of the condensation pan. This slight tilt can be a reason why the portable aircon is leaking.

Adjust the aircon so that it remains level. Some units also need a slight tilt backward to prevent water leakage. 

5. Broken Pump

Some aircon units still use a pump to remove extra water from the unit. Thus, a properly functioning pump is essential to remove the collected water. If the pump malfunctions, water can accumulate in the unit and can leak to the outside. Thus, check the pump to see if it is working properly. A broken pump might need replacement.

6. Low Refrigerant

Low refrigerant can lead to the aircon not exchanging the hot air properly. Low refrigerant causes ice formation in the evaporator coils, which then melt to cause water leakage from the unit.

Thus, get a technician to look at the gas levels of your aircon unit. You might want to consider filling the gas if the levels are low.

7. High Humidity levels 

The aircon may struggle to remove extra moisture in high humidity levels. Thus, water buildup may occur, leading to water dripping from the unit. You can also use a dehumidifier to remove extra moisture from the room. You should also ensure that the air con’s drainage is proper.
