Why does the car air conditioner have cold air but not cool enough?
2 Answers
Here are the reasons why the car air conditioner has cold air but is not cool enough: 1. Lack of refrigerant: Sometimes there is an issue with the refrigerant in the car air conditioning system. 2. Loose air conditioning compressor belt: When the belt driving the car air conditioning compressor is loose, the compressor will slip during operation. 3. Dirty condenser: It is often found in summer that the air conditioning does not work well. 4. Clogged air filter: If the filter is too dirty, it will affect the airflow. Here is additional information on why the air conditioner is not cooling: 1. Internal damage: Severe internal wear of the compressor can prevent it from working properly. 2. Oil stains: Oil stains at connection points or seams indicate refrigerant leakage, and the relevant parts should be tightened or replaced. 3. Circuit system failure: Circuit system failures are also a very common reason why the car air conditioning compressor cannot work normally. You can check if the circuit is unobstructed, inspect the temperature sensor solenoid valve, and other potential fault causes. 4. Low-pressure gauge reading much lower than normal: The surface temperature of the compressor suction pipe is lower than normal, appearing damp and cold (commonly known as sweating).
I found that the car's air conditioning has cold air but it's not cooling properly, which is mostly caused by insufficient refrigerant or a leak. Refrigerant is like the blood of the air conditioning system; without enough of it, the cooling effect won't be achieved. Compressor aging is also a common issue—if it's not running smoothly, cold air won't come out. I often see the condenser clogged with dust or leaves, leading to poor heat dissipation and an immediate drop in air conditioning efficiency. Additionally, a dirty air filter can block airflow, reducing the cooling effect when the cold air is blown out. If none of these components are the issue, it might be an internal system leak or a malfunctioning thermostat. It's best to visit a repair shop for a thorough inspection without delay, as it affects driving comfort. Regular maintenance before seasonal changes can prevent this problem from occurring.
