Condenser
During the cooling process of the air conditioner, condensed water will inevitably be produced. Condensed water is generated in the indoor unit and then flows outdoors through the condensed water pipe. Therefore, we can often see water dripping from the outdoor unit of the air conditioner. At this time, there is no need to worry at all, this is a normal phenomenon.
Condensed water flows from indoors to outdoors, relying on natural gravity. In other words, the condensate pipe must be on a slope, and the closer to the outside, the lower the pipe should be so that the water can flow out. Some air conditioners are installed at the wrong height, for example, the indoor unit is installed lower than the air conditioning hole, which will cause condensed water to flow out from the indoor unit.
Another situation is that the condensate pipe is not fixed properly. Especially in many new houses now, there is a dedicated condensate drainage pipe next to the air conditioner. The condensate pipe of the air conditioner needs to be inserted into this pipe. However, during the insertion process, there may be a dead bend in the water pipe, which prevents the water from flowing smoothly.
There is also a more special situation, that is, the condensate pipe was fine when it was installed, but then a strong wind blows the pipe away. Or some users reported that when there is a strong wind outside, the indoor air conditioner leaks. These are all because the outlet of the condensate pipe is warped and cannot drain. Therefore, after installing the condensate pipe, it is still very necessary to fix it a little.
Installation level
If there is no problem with the drainage of the condenser pipe, you can blow on the condenser pipe with your mouth to see if it is connected. Sometimes just blocking a leaf can cause the indoor unit to leak.
After confirming that there is no problem with the condenser pipe, we can go back indoors and check the horizontal position of the indoor unit. There is a device inside the indoor unit for receiving water, which is like a big plate. If it is placed at an angle, the water that can be collected in the plate will inevitably be less, and the water received in it will leak from the indoor unit before it can be drained.
Air-conditioning indoor units are required to be level from the front to the rear and from the left to the right. This requirement is very strict. Sometimes a difference of only 1cm between the two sides will cause water leakage. Especially for old air conditioners, the bracket itself is uneven, and level errors are more likely to occur during installation.
The safer way is to pour water for a test after installation: open the indoor unit and take out the filter. Connect a bottle of water with a mineral water bottle and pour it into the evaporator behind the filter. Under normal circumstances, no matter how much water is poured, it will not leak from the indoor unit.
Filter/Evaporator
As mentioned earlier, the condensed water of the air conditioner is generated near the evaporator. As more and more water is produced, it flows down the evaporator and onto the catch pan below. But there is a situation where the condensed water no longer enters the drain pan, but directly drips down from the indoor unit.
That means the evaporator or the filter used to protect the evaporator is dirty! When the surface of the evaporator is no longer smooth, the flow path of the condensate will be affected, and then flow out from other places.
The best way to solve this problem is to remove the filter and clean it. If there is dust on the surface of the evaporator, you can buy a bottle of air conditioner cleaner and spray it on, the effect is also very good.
The air-conditioning filter needs to be cleaned once a month, and the longest period should not exceed three months. This is to prevent water leakage and also to keep the air clean. Many people feel sore throat and itchy nose after staying in an air-conditioned room for a long time, sometimes because the air from the air-conditioner is polluted.
