What is a common symptom of an overcharged refrigeration system?

Frost buildup on the evaporator is a common symptom of an overcharged refrigeration system. When the refrigerant levels are too high, it can lead to an increase in pressure within the system. This excess pressure can cause improper heat exchange in the evaporator. As the refrigerant struggles to absorb heat, it can cause the temperature in the evaporator to drop below freezing, leading to frost or ice accumulation on the evaporator coils.

This frost buildup can hinder the performance of the refrigeration system, resulting in inefficient cooling and possibly leading to compressor damage if not addressed. Identifying frost or ice on the evaporator is crucial for diagnosing issues in a refrigeration system, as it indicates a problem related to refrigerant charge levels.
