What's the matter if the air conditioning pipe is not cold

There are three reasons why the large pipe of the air conditioner is not cold, such as blockage of the refrigeration system, dust accumulation on the filter screen and lack of refrigerant. At this time, we need to carefully observe and distinguish, find the main reason why the large pipe is not cold, and then solve it.

1. The refrigeration system is blocked

If the air conditioner is used for a long time, its refrigeration system will inevitably have some problems, such as being blocked, which makes it difficult to cool. At this time, when we observe the air conditioner, we will find that the small pipe is relatively cold, while the large pipe is not cold. It needs to be cleaned in time to ensure the normal use of the air conditioner.

2. Dust accumulation on filter screen

Too much dust accumulated by the filter screen will also lead to the cold of the air conditioning pipe, because the cold air of the air conditioning can not pass through the filter screen well at this time, resulting in the cold of the pipe and the low air in the house.

3. Lack of refrigerant

When the main pipe is not cold, we can turn on the air conditioner normally for about ten minutes. Listen to the sound of the compressor. Basically, it is always running for a while. It is mostly due to the lack of refrigerant and needs to be added in time.
