Why is the truck air conditioning not cooling?

[DeRose]

Truck air conditioning not cooling may be due to insufficient refrigerant or damaged air conditioning flaps. Below are the related reasons for truck air conditioning not cooling: 1. Quality and purity of refrigerant: The quality and purity of refrigerant play a crucial role in vehicle air conditioning. Typically, inferior refrigerant can lead to inefficient operation of the air conditioning system. 2. Condenser and radiator: The heat dissipation condition of the condenser and radiator also affects the performance of the air conditioning. Long-term accumulation of dust and debris can cover the condenser and radiator if not cleaned regularly. 3. Excessive use of refrigerant: Many truck owners believe that more refrigerant in the air conditioning system is better, but this is not the case. During refrigerant charging, the amount should be neither too much nor too little. Too little refrigerant results in insufficient pressure in the air conditioning pipes, while too much leads to excessive pressure. In both scenarios, the air conditioning system cannot operate normally to provide cooling.
