Due to a broken drain pipe
The most common cause of air conditioner leaking water in the outdoor unit is a broken drain pipe.
Usually, when the air conditioner operates for a long period of time, the humidity in the room is separated from the air before falling to the evaporator coil and then forming water and dripping into the drip tray, forming flowing streams into the drain pipe. Therefore, if the drain pipe is broken, the water inside will leak out.
How to fix: In this case, you can buy a new pipe to replace it yourself or call a repairman.
Due to dust buildup on the evaporator coil
After using the air conditioner for a period of time without cleaning or maintenance, dust buildup can occur and may lead to a clogged drain pipe.
Due to low refrigerant
Air conditioners with low refrigerant are also one of the causes of air conditioner leaking water in the outdoor unit. Because insufficient refrigerant will cause the evaporator coil to frost, the air conditioner cannot maintain the right temperature and causes the ice to melt through the drip tray, overflowing.
How to fix: This is a case where you cannot fix it yourself and need the intervention of a repairman. Besides calling a repairman, check if there are any obstacles blocking the outdoor unit (such as cardboard, fabric, plastic bags...) as this can also be a cause of water leakage.
Due to installation errors
During installation, inexperienced technicians may install water pipes without the proper slope or use excessively long pipes without ventilation holes. This results in water not draining properly and flowing back into the water tray, causing this issue.
These are the main causes of air conditioner leaking water in the outdoor unit and how to fix it. Remember these tips to prevent this from happening to you.
