What is a common indicator of a clogged filter in a refrigeration system?

The identification of a clogged filter in a refrigeration system is often indicated by reduced airflow, increased system pressure, and suboptimal cooling performance. When a filter becomes clogged with debris or dirt, it restricts the flow of air through the system. This lack of proper airflow can cause a buildup of pressure within the system, leading to inefficiencies in heat exchange and cooling performance.

Additionally, because the refrigerant cannot move as effectively through the system due to the clogged filter, the cooling capacity diminishes. This results in the refrigeration unit working harder to maintain the desired temperature, which can lead to elevated pressures on both the low and high sides of the system. Consequently, technicians use these symptoms to diagnose potential issues with filters in refrigeration systems effectively.
