What Causes Poor Cooling Performance When the Car Has Sufficient Freon?

[DelBrayden]

Reasons for poor cooling performance despite sufficient Freon in the car include: 1. Refrigerant leakage: A common cause of ineffective car air conditioning is insufficient or low refrigerant levels, often due to minor leaks. 2. Excessive refrigerant: The proportion of refrigerant in the air conditioning system must meet specific requirements. Too much refrigerant can impair heat dissipation, similarly, adding too much cooling oil during maintenance can also reduce the system's heat dissipation capacity. 3. Loose drive belt of the car air conditioning compressor: Car cooling relies on refrigerant, which is transported by the air conditioning compressor, with the drive belt being a crucial moving part. If the drive belt is loose, the compressor may slip during operation, leading to reduced transmission efficiency, slower compressor speed, and decreased refrigerant delivery, resulting in poor cooling performance.
