What are the reasons and solutions for poor cooling performance of car air conditioning?

[JeffreyFitz]

Reasons for poor cooling performance of car air conditioning: 1. Insufficient refrigerant causing inadequate cooling; 2. Moisture infiltration in the air conditioning refrigeration system leading to insufficient cooling; 3. Reduced heat dissipation capacity of the condenser resulting in decreased air conditioning cooling performance; 4. Aging compressor and belts; 5. Blocked refrigeration pipelines; 6. Long-term failure to replace the air conditioning system's filter; 7. Malfunctioning cooling fan. Solutions for poor cooling performance of car air conditioning are: 1. Add refrigerant; 2. Use a soft brush to remove dirt from the condenser surface; 3. Replace the compressor and belts; 4. Clear blocked refrigeration pipelines; 5. Regularly replace the air conditioning system's filter; 6. Inspect and repair the cooling fan.
