What are the reasons for the weak air conditioning in the tenth-generation Civic?

The reasons why the tenth-generation Civic's air conditioning is not cooling are as follows: 1. Lack of refrigerant: A lack of refrigerant is a normal situation, not a malfunction. The air conditioning will not completely fail to cool, but its performance will be poor. However, this situation should be relatively rare because refrigerant is not a consumable. As long as the vehicle has not been involved in a severe rear-end collision or had its air conditioning pipeline and other components disassembled, affecting the sealing, the refrigerant will not deplete on its own. 2. Internal damage to the air conditioning pump: Such as damage to the piston rings inside the air conditioning pump or damage to the clutch disc. This can cause the air conditioning pump to fail to operate, thereby preventing the initiation of the cooling effect. Generally, damage to the air conditioning pump will produce abnormal noises. 3. Compressor damage: When the compressor is damaged, it either stops working or the pressure difference in the high and low-pressure pipelines becomes very small. This situation will result in the air conditioning not cooling.
When driving my 10th-gen Civic, I encountered an issue with the AC not cooling properly, which is usually caused by a few minor reasons. The most common one is insufficient refrigerant, possibly due to a system leak, and adding R134a can solve it. If the compressor is severely worn, not working, or has reduced efficiency, the cooling effect will be poor. Another issue is a clogged filter—dust buildup can block airflow and hinder cooling. A faulty fan or radiator can also cause heat exchange failure. I recommend checking these yourself first; replacing the filter costs less than 100 yuan, saving money and effort. If that doesn’t work, visit a professional repair shop promptly—don’t wait until summer when the heat becomes unbearable, affecting visibility and comfort. Regular AC system cleaning can prevent this; once a year is enough.
