What is the effect of overcharging an AC system with refrigerant?

Overcharging an AC system with refrigerant leads to increased pressure within the system. When there is too much refrigerant, it can exceed the design specifications of the components, causing excessive strain. This elevated pressure may lead to potential system failure, such as compressor damage, as the compressor is not designed to handle pressures that are significantly higher than normal operating conditions. Moreover, overcharging can cause serious performance issues like reduced cooling efficiency, increased energy consumption, and potential leaks due to the additional stress placed on seals and fittings. Proper refrigerant levels are crucial for the effective and safe operation of an AC system.
