What is a common cause of low refrigerant levels in a refrigeration system?

Low refrigerant levels in a refrigeration system are commonly caused by refrigerant leaks. Over time, systems can develop small leaks due to wear and tear on components, poor sealing, or physical damage. When refrigerant escapes, the system is not able to maintain the correct pressure and temperature levels required for effective cooling. Detecting and repairing these leaks is crucial for restoring system efficiency and preventing further damage.

High ambient temperature, while it can affect system performance, does not directly cause low refrigerant levels. A faulty compressor might lead to inadequate cooling, but it does not inherently result in lower refrigerant amounts. Inadequate insulation can cause a refrigeration system to work harder and might create some inefficiency, but it does not directly contribute to losing refrigerant from the system.
