Poor cooling and bad smells are the most frequent complaints. MSG Equipment explains causes such as refrigerant leaks, blockages and compressor faults.
Car air conditioning is used not only in summer but also in spring and autumn to fight humidity and fogged windows, and in electric vehicles it extends battery life by preventing overheating. MSG Equipment’s article reviews common faults and the equipment used to diagnose them.
Customers most often complain of weak or no cooling and unpleasant odours when the system runs. Causes of poor cooling include:
- refrigerant leaks,
- blockages in system components,
- compressor and electronic faults.
Less refrigerant means lower efficiency and a higher compressor load. To measure the amount accurately, the refrigerant must be fully recovered with an A/C charging station, the article notes.
