What should I do if I use an air conditioner for 6 or 7 years and the refrigeration effect is not go

The return air filter of the indoor unit of the air conditioner is too dirty, or the electronic control parts of the air conditioner are aging and damaged.

Generally speaking, the air conditioner can be used continuously for 5 years after installation, indicating that there are no obvious defects in the original installation of the air conditioner, resulting in problems with the air conditioner after 5 years of use, the biggest possibility is that the return air filter of the indoor unit is too dirty, dirty to the extent of basic blockage, or the electronic control components are aging and damaged. When the indoor return air filter is too dirty, resulting in a large attenuation of the air volume of the indoor unit of the air conditioner, the air conditioner is prone to evaporator icing, and the air conditioner is shut down intermittently. When the electronic control components, especially the capacitors of the outdoor fan motor and compressor, are aging, it is easy to cause the compressor to have a protective shutdown and cannot be used normally.

Suggested treatment:

1. Clean the return air filter of the indoor unit, dry the water and put it back;

2. Continue to observe the operation status of the air conditioner, if the air conditioner can continue to start running after a few minutes or ten minutes after the compressor is stopped, and then stop running, it means that the heat exchanger of the outdoor unit is too dirty and the capacitor is aging and the heat exchanger of the outdoor unit is poor, and the heat exchanger of the outdoor unit needs to be cleaned or replaced with a new capacitor of the same specification.

The refrigeration effect of the air conditioner is not good, and it is likely that the air conditioner refrigerant is not enough. The most important thing is to add refrigerant.

Hope, thank you.

First of all, it is necessary to clean up the outer and inner units, because after a long time, there is dust inside, which affects the refrigeration.

Since it is an air conditioner that has been used for six or seven years, either the refrigerant is insufficient and needs to be repaired, and the refrigerant can be added, so it is recommended to find a maintenance personnel to take a look.

Add the air conditioner freon refrigeration effect to the effect. After the air conditioner is used for a long time, the freon in it will be lost, which will affect the cooling effect of the air conditioner.

The air conditioner has been for a long time, and the natural effect is definitely not good, so it must be better to change it at this time.

It is estimated that there is a lack of refrigerant, and after-sales professional maintenance personnel are found to test and repair.

There are many reasons why an air conditioner does not refrigerate well, and it is best to ask an air conditioner repair professional to find out the specific cause.

The air conditioner that has been used for 67 years is not working well, and you should find a maintenance master for repair.

The general household air conditioner has been used for a long time, and the problem of poor refrigeration effect will occur, which is a normal phenomenon. Refrigeration is mainly related to the operation of the compressor, and the poor refrigeration may be due to the failure of the pressure disturbance and shrinkage machine, or the lack of refrigerant. Let's talk about the causes of poor refrigeration and the solutions:

1. The dust filter of the indoor unit is blocked. The air conditioning filter of the indoor unit of the air conditioner is generally installed at the position of the air outlet, and when this filter is blocked, the cold air of the air conditioner cannot flow out completely through the air outlet. Workaround:

Open the cover of the indoor unit, remove the dust filter, scrub it with a discarded toothbrush, and then install it back after brushing it clean. 2. Lack of refrigerant. After the air conditioner is used for a long time, the refrigerant will be lost more or less, and the refrigerant effect will not be good after the lack of refrigerant.

Solution: Add a certain amount of refrigerant. It is recommended to ask a professional master to add a delay in this operation, so as to avoid other errors when the user adds it by himself.

3. Lack of fluorine in the system. After using the air conditioner for a few years, there is no bad refrigeration, most of which is due to the lack of fluorine. Workaround:

Turn on the inner unit of the air conditioner and add a certain amount of fluorine. 4. The compressor is damaged. The refrigerant releases the cold air through the high pressure of the compressor, and when the compressor has a problem, the refrigerant cannot release the cold air.

Solution: Replace the compressor with a new one.

First of all, check the air conditioner settings, whether the air conditioner temperature is set high, and whether the operation mode is refrigeration mode.

When the air conditioner is cooling, the cooling mode should be set, the icon is a snowflake icon, and the temperature should be set a few degrees lower than the room temperature.

Secondly, check whether the internal and external units of the air conditioner are dirty and blocked, and clean them if they are dirty.

Test again whether the refrigerant is sufficient, and if it is insufficient, make up the amount.

If you don't understand anything, you can also call us for consultation or repair.

If the refrigeration effect is not good, the possible situations are as follows;

1. The refrigerant is insufficient, the system leaks fluorine, and it needs to be charged.

2. The air-conditioning system is blocked.

3. The condenser of the external unit is too dirty, resulting in poor heat dissipation, and it needs to be cleaned 4. The filter screen of the internal unit is too dirty, resulting in insufficient air volume at the air inlet, and it needs to be cleaned 5. The lubricating oil is insufficient, and the compressor is seriously worn.

This situation is basically that the heat dissipation of the host is not good, and it is recommended to try it after cleaning, which will have unexpected effects.
