Chevrolet Spark intermittent air conditioner issue with loss of cold air after an hour on Chevrolet Spark

Some Chevrolet Spark owners report experiencing intermittent air conditioning issues, such as losing cold air after about an hour of operation. Common factors contributing to this problem include refrigerant leaks, which can lead to a gradual loss of cold air, and compressor failures that prevent the AC system from maintaining consistent cooling. Additionally, clogged condensers are known to reduce cooling efficiency, while electrical issues can cause intermittent cooling or complete failure of the system. A dirty cabin air filter may also hinder airflow and overall performance. In cases where the AC stops working entirely after an hour, a system leak and lack of coolant could be the cause. To resolve these issues, it is recommended that owners have their AC system inspected by a qualified mechanic for proper diagnosis and repairs.
