What are the reasons for the air conditioning not cooling in a new car?

[LaChase]

The most likely reason for the air conditioning not cooling in a new car is the lack of refrigerant. Generally, unless the car is purchased in summer, owners do not carefully check or request the 4S store to refill the refrigerant. As a result, after driving the car for a while, when summer comes and they want to use the air conditioning, they realize there is no refrigerant, leading to no cooling. The daily maintenance of car air conditioning can be roughly divided into the following two parts: 1. Regularly clean the air conditioning filter: Otherwise, over time, the filter can easily breed bacteria and emit a musty smell. If not cleaned for a long time, the dust attached to it will be blown into the car when the air conditioning is turned on. 2. Periodically clean the air conditioning radiator: Frequent use of the air conditioning in summer can lead to the growth of dirt, dust, and bacteria in the air conditioning ducts, which can affect human health.
