1. Does it matter if the air conditioner is not used for a long time?
The core of the air conditioner is the compressor, which contains lubricating oil. If it is not used for a long time, the lubricating oil will condense, and the compressor may be stuck when it is used again.
Special reminder: In the season when no air conditioner is used, it is best to keep the usage of turning on once a month.
2. The refrigerant needs to be changed once a year?
Many users feel that the air conditioner has been used for a period of time, they must change the refrigerant, in fact, this view is not correct. The statement that the air conditioner needs to change the refrigerant regularly is nonsense. The air conditioner is cooled by refrigerant like a refrigerator, but since the refrigerator is a closed type refrigeration device, there is never need to add refrigerant. The refrigeration system of the air conditioner is a semi-closed type. Generally, there will be refrigerant leakage in the refrigeration process, so sometimes it needs to add refrigerant. However, the leakage of refrigerant for each air conditioner is different, so there is no specific time specified, the user must be replaced. In fact, air conditioners that use four or five years without adding refrigerants are everywhere.
3. Only need to wash the filter to clean the air conditioner?
Among all household appliances, air-conditioning dust pollution is the most serious, and the cleaning of air-conditioning is also the most overlooked thing. Some users use it for many years after installing the air conditioner, and never clean it until it breaks down.
Special reminder: air conditioners generally need to be cleaned and maintained before use in summer or after use in autumn. In fact, the cleaning of the air conditioner can be done by the user under normal circumstances.
The first is to clean the internal machine. The filter must be cleaned, and the photocatalyst in the air conditioner needs to be exposed to the sun for ten minutes before use to maintain its function. If it is used for a long time, there is a lot of wind and dust in the internal machine, and the evaporator also needs cleaning. Air conditioners that work in areas with relatively large oil fumes require the entire air conditioner to be removed and fully cleaned.
In addition to the internal machine, the external machine must also be cleaned. If the external unit is not hung outdoors, users can clean the condenser and heat exchanger with clean water.
