A refrigerant overcharge has a significant and detrimental effect on the refrigeration system. When too much refrigerant is added to the system, it results in excessive pressure within the components. This increased pressure can lead to several issues, including the risk of leaks, rupture of components like hoses or seals, and even a complete system failure.

The overcharged refrigerant can restrict the flow of the refrigerant, preventing optimal heat exchange from occurring within the evaporator and condenser. This not only diminishes the efficiency of the cooling performance but also raises operational temperatures, which can lead to overheating and further damage to the compressor and other vital components.

Proper refrigerant levels are crucial for maintaining the efficiency and longevity of the refrigeration unit, and an overcharge disrupts this balance, leading to potential mechanical failures and costly repairs. Thus, understanding the consequences of refrigerant overcharging is essential for maintaining a properly functioning refrigeration system.
