What's wrong with Gree air conditioning not cooling? Nanchang air-condition maintenance

Check whether the air conditioner works normally, including indoor unit and outdoor unit. Check the compressor of the outdoor unit. If one of them is abnormal, please ask the master to repair it. Check the filter. If the air conditioner starts normally, but there is no cold air, it is likely that there is too much dust in the filter, so it should be cleaned with a special filter cleaner. Check whether the refrigerant is insufficient, which is called freon. If it is not enough, add freon. How to deal with air conditioning without refrigeration 1, air conditioning refrigeration needs a certain voltage, if the voltage is not enough, it is likely to affect the performance of air conditioning, which directly leads to air conditioning without refrigeration. In view of this situation, it is necessary to buy a voltage regulator to stabilize the voltage and avoid the peak period of electricity consumption. 2. Generally speaking, this is a common reason why Gree air conditioners are not cooled. Because the power of air conditioning is generally fixed, generally speaking, a certain power of air conditioning corresponds to a certain indoor area. If the indoor area is large and the power of the air conditioner is small, it is very likely that the air conditioner will not cool. In view of this situation, it is necessary to check whether the air conditioning power is sufficient. 3. The air conditioner contains a certain amount of refrigerant. If the air conditioner is used for a long time and the refrigerant consumption is not replenished in time, the refrigeration effect will be poor due to insufficient refrigerant. On the other hand, the cooling effect may be insufficient due to refrigerant leakage. In view of this situation, it is necessary to check whether the refrigerant is sufficiently replenished or leaked for maintenance.
