God, why is it still so hot in the air-conditioned room?

I. Not caused by air conditioning failure

1. The air filter screen is blocked, resulting in slow cooling. Clean the filter screen in time.

2. The temperature set by the temperature regulating switch is not appropriate.

3. There are obstacles in front of the outdoor unit, which affect the normal work of the air conditioner. Clean or install air conditioners in open areas without obstacles.

4. The doors and windows of the room are not closed properly, and the indoor sealing is not done well. Do not open and close doors and windows frequently, and keep the air-conditioned room closed.

5. There is strong direct sunlight coming in or shining on the air conditioner. It is suggested to install curtains in the room and close them when the sun is shining.

6. The air volume is set at the "low wind" position, and the air conditioner runs at a low speed. To achieve the cooling effect, increase the air volume as much as possible.

7. There are too many people in the room, resulting in too much heat to adjust the temperature quickly. It is common sense that there should not be too many people in an air-conditioned room.

8. The indoor area is too large, and the cooling capacity of the air conditioner is too small to meet the actual use requirements. Pay attention to this problem when shopping, and be sure to choose the appropriate air conditioner according to the room area. For example, 1 air conditioner correspondence 12~ 15 square meters.

9. Heating elements such as electric heating appliances are being used at home, resulting in insufficient power of air conditioners, which makes the air conditioners not cool or the cooling effect decline. Try not to use high-power electrical appliances at the same time.

10. The power supply voltage is insufficient. If the voltage is often unstable, it is recommended to install a voltage regulator.

Second, caused by air conditioning failure

1. Freon is not enough (commonly known as insufficient snow species). Find a professional to check whether there is a shortage of fluorine and replenish it in time.

2. There is no good solution to the situation that the air conditioner is not cooled due to the high temperature of the external environment.

3. The air conditioner is not cleaned for a long time. The cleaning of air conditioning is an essential link in air conditioning maintenance.

4. The steel pipe between the outdoor unit and the indoor unit is too long, so it is suggested to shorten the length of the steel pipe.

5. The motherboard problem, the circuit can't send electricity, so the motherboard should be replaced.

6. If the air conditioner you just bought doesn't cool, you should consider whether the air conditioner has quality problems. It is recommended to buy a first-line brand air conditioner, the quality and after-sales can be insured.

7. The compressor problem. The compressor is aging and inefficient before it is used for too long. Like the sound and vibration of the air conditioner, it is necessary to consider whether it is a compressor problem. Such problems can only be repaired by professionals, or consider buying a new machine.
