The purpose of AC compressor oil is to keep all parts lubricated and help cool the various moving parts in the compressor.
In addition, the oil film protects the rubber seals -in the refrigerant lines and at joints/connections- greatly reducing the volume of refrigerant that leaks out.
As a result, an AC compressor can fail to cool air or have all kinds of problems if it doesn’t have enough oil.
The best way to prevent this issue is to keep an eye on the AC compressor low oil symptoms and to act when you notice signs of declining oil levels.
Below we explain all the common AC compressor low oil symptoms to help you learn when it needs an oil refill.
