1. Not enough refrigerant
Once the air conditioner fails to cool, the first reaction of most people is: there is not enough Freon
Normally, the freon in the air conditioner is strictly sealed, and as long as it does not leak, it can last at least five or six years.
However, if the machine itself is not good enough, the operation of the air conditioner is not standardized during installation, the machine is moved, the pipeline is aging... it may also cause Freon leakage, resulting in poor air conditioning cooling effect.
2. The refrigeration capacity of the air conditioner does not match the room area
Here we can first figure out a concept: the number of horses of the air conditioner
The number of horses of the air conditioner refers to the cooling capacity. In general, the cooling capacity of 2300~2600W is called one horse, 3200~3600W is 1.5 horses, and 4500~5500W is 2 horses.
3. Inadequate cleaning and maintenance of air conditioners
If the outdoor unit of the air conditioner is used for a long time, it will easily adhere to a lot of dust and garbage, resulting in poor heat dissipation effect of the radiator, making the air conditioner not cooling, and easily causing unsanitary indoor air.
Fourth, the voltage is unstable
This situation is likely to occur during peak electricity consumption periods, such as noon on weekends when the temperature approaches 40°C. The solution is to install a voltage stabilizer to help protect the home appliances.
5. The weather is too hot
When the outdoor temperature is too high and exceeds the cooling limit of the air conditioner, the air conditioner may not be cooled. For example, in the equatorial region, fan air conditioners are not very useful.
6. Installation problems
When installing, if the steel pipe between the outdoor unit and the indoor unit is too long, it will also cause low heat transfer efficiency and insufficient cooling capacity of the air conditioner. In this case, shorten the length of the steel pipe as much as possible.
7. Equipment reasons
Is there any problem with the quality of the air conditioner itself; the second is whether the parts of the air conditioner itself are aging, damaged and cannot be used.
