Are Small-Displacement Car Air Conditioners Not Cooling Enough?

[SanCayden]

Small-displacement car air conditioners may not cool effectively due to their limited engine capacity. Here are the reasons why the air conditioner might not be cooling: 1. Internal Damage: Severe internal wear of the compressor can prevent it from functioning properly. 2. Oil Stains: Oil stains at joints or seams indicate refrigerant leakage, requiring reinforcement or replacement of the affected parts. 3. Electrical System Failure: Faults in the electrical system often prevent the car air conditioner compressor from working correctly. It's advisable to check the circuit for continuity and inspect the temperature sensor solenoid valve and other potential faults. 4. Low-Pressure Gauge Reading Much Lower Than Normal: The suction pipe surface temperature of the compressor is lower than usual, accompanied by a damp and cold phenomenon (commonly known as sweating).
