What is the solution of air conditioning not cooling

There are many reasons why the air conditioner is not cooling. For example, if the air conditioner refrigerant is insufficient, you can find a professional to add snow; secondly, it may be caused by the error of the air conditioner installation, such as the ventilation pipe is too long. It is recommended to shorten the length of the ventilation pipe; A lot of dust stains accumulate on the radiator and cause no cooling. It is recommended to clean the air conditioner.
