The long-term work of the air conditioner is definitely not possible without cleaning and maintenance. The most obvious sequelae is that the cooling effect will deteriorate. External air conditioners are often easily overlooked by people, and dust may accumulate to affect heat dissipation for a long time. So the correct approach is to clean and maintain the air conditioner external unit every few months.
2. Replace the old air conditioner over the service life

The normal service life of the air conditioner is about 10 years. After more than 10 years, the components inside will begin to show different degrees of aging. Even if individual parts are replaced, other components will slowly start to have problems, resulting in a serious decline in the performance of the air conditioner. , The maintenance cost is too high, so it is recommended to replace such old air conditioners over the age of use
3. Check whether the copper pipes of the indoor and outdoor units of the air conditioner are too long

When the air conditioner is installed, many people think that the external unit is too noisy when it is in operation, so they want to install the external unit far away. In fact, this is unscientific, which will not only increase the installation cost, but also cause the cooling performance of the air conditioner to decline. The correct approach is to reduce the length of the indoor and outdoor unit copper tubes as much as possible to achieve the best working effect of the air conditioner.
4. Check whether the power of the air conditioner matches the indoor space

The power of the air conditioner is generally proportional to the size of the space. In order to save money, some people buy the air conditioner with too little power, and if the room is relatively large, the cooling effect is definitely very poor. The correct approach is to purchase air conditioners, we must calculate the applicable area of the air conditioner, on this basis, add 0.5 to 1 horsepower is the best.
5. Check whether the installation environment of the air conditioner is suitable
When the outdoor temperature is too high, it is difficult for the air conditioner to conduct the indoor heat to the outdoor environment through the external unit, resulting in the air conditioner being unable to cool. So the correct way is to replace the external machine to a more ventilated place to avoid direct sunlight.
6. Replenish refrigerant
After the air conditioner is used for a long period of time, refrigerant loss or leakage will occur, resulting in poor cooling effect of the air conditioner. The correct way is to find air-conditioning after-sales personnel to add fluoride treatment to the air-conditioning, and check whether there is a phenomenon of fluorine leakage.
