After a period of use, LG air conditioners will accumulate dust and dirt, affecting the device. Let’s refer to the simple way to clean LG air conditioners at home in the article below to ensure operation and longevity.
1.What are the signs that LG air conditioner needs cleaning?
Regularly cleaning the air conditioner not only helps increase the life of the device but also helps you save on power consumption. In addition, doing this periodically will help you detect potential problems and unexpected incidents early. You need to clean the air conditioner as soon as you notice the device has the signs listed below.

- LG air conditioner gives off an unpleasant odor
Dust in the air will accumulate on the machine parts over time, causing mold and creating conditions for bacteria to grow. The air conditioner will then blow out an unpleasant smelling air stream that affects the health of consumers.
- Weak cooling capacity of the device
The obstruction of large amounts of dirt in the filter over time will prevent the cool air from circulating effectively. This makes the device unable to provide optimal cooling temperature compared to the temperature displayed on the control.
- LG air conditioner is frozen
The condition of the air conditioner being frozen is due to the filter of the machine being clogged with a large amount of dirt, along with the amount of refrigerant exceeding the necessary conditions. If the device is continued to be used for a long time at high capacity without cleaning, it will cause freezing.
- LG air conditioner is leaking water
Water from the air conditioner will flow back out if the drain pipe is clogged with dirt and debris. Therefore, learn and perform regular cleaning methods for LG air conditioners to ensure optimal performance of the device.
2. When should LG air conditioner be cleaned?

Before learning how to properly clean LG air conditioners, you should first pay attention to the time frames that need to be done. The time frame for periodic air conditioner cleaning will vary depending on the environment and frequency of use. You can refer to the suggested time frames below:
- For households: should clean after about 3-6 months/time if the frequency of use is not too high. For families with higher frequency of use, should clean at least 3 months/time.
- For companies/restaurants/hotels: on average, cleaning should be done about once every 3 months or once every 1-2 months for dusty environments.
- For production facilities: the production environment should be cleaned at least once a month to ensure optimal performance and cooling capacity of the equipment.
