　　4. When cleaning the panel, use a soft cloth dipped in warm water or neutral detergent to wipe gently, and then wipe it dry with a dry soft cloth.

In fact, as long as there is no problem with the installation of the machine, there is generally no need to add liquid within five or six years. Hard addition will increase the burden on the compressor and burn the compressor.

　　 6. When cleaning the central air conditioner, do not clean it carelessly. Some people do not have professional cleaning techniques. They often just flush the filter with water and spray a cleaning agent into the air conditioner. They do not clean the central air conditioner at all. Such cleaning is a formality and has no practical meaning for cleaning the air conditioner. Only the complete disassembly and cleaning of the indoor unit can play the role of dust removal and sterilization.

　　 7. Beware of cheap bait. The most common trick used by unscrupulous businesses is to commit fraud in the name of central air-conditioning cleaning. Some businesses have found out the psychology of some consumers that only value prices, and often low prices are used as bait. Then in the process of cleaning the central air conditioner, he tried every possible means to find faults in the air conditioner, and finally held back on the excuses of replacing parts, repairing, and adding freon.

　　 8. No need for inferior cleaning agents. To clean the central air conditioner, in addition to the professional cleaning staff, the cleaning agent used is also critical. In order to reduce costs, some people often use inferior cleaning agents. Especially for some corrosive cleaning agents, once sprayed into the air conditioner, if it is not rinsed with a high-pressure water gun, it will cause great damage to the air conditioner.
