First, it is important to note that the phenomenon of air conditioners (also known as coolers) emitting mist, vapor, or even small water droplets is quite normal.
Typically, before turning on the air conditioner, the temperature and humidity in the room are high. If we set the temperature low, the air conditioner will cause the moisture to condense into mist or tiny water droplets, which can also appear as a layer of humid air.
Air conditioners emitting mist is not a serious issue.
After the air conditioner has been running for a while, this phenomenon will cease due to its dehumidification function. You shouldn’t worry too much in this case; it will resolve on its own.
However, if the air conditioner is releasing a significant amount of water that even runs down the walls, the cause might be a clogged drainage system (blocked drainage tray, blocked drainage pipe, etc.), and you need to maintain (clean) the air conditioner thoroughly.
Note when the air conditioner emits white smoke.
In large cities, the dust concentration in the air is very high, causing the air filter in the air conditioner to become clogged quickly. Therefore, you need to clean the filter regularly. However, after a long period, besides the dust filter, the coil unit (the internal part of the cooling unit) gets clogged with dust, which can cause the unit to not cool properly, leak water, produce weak airflow, and create unpleasant odors due to mold, affecting the health of everyone, especially infants and the elderly.
To avoid this situation, you need to regularly clean and maintain the air conditioner, wash the filter, etc. Additionally, you should schedule maintenance for your air conditioner every 3-4 months to protect your health, your family, and to increase the lifespan of your air conditioning unit.
