What are the potential consequences of overcharging an HVAC system with refrigerant?

Overcharging an HVAC system with refrigerant can lead to increased pressure within the system, which poses a significant risk to its components, especially the compressor. The compressor is designed to handle a specific pressure range; exceeding this range can result in mechanical failure due to excessive strain. This can lead to a failure of the compressor, resulting in costly repairs or even the need for a full replacement of the system.

Understanding the impact of refrigerant levels on system performance is critical, as not only does overcharging affect the compressor, but it can also disrupt the overall balance of the HVAC system, leading to inefficient operation and a decrease in longevity. The other options describe various issues that might arise from refrigerant undercharging or other operational problems rather than the specific consequences tied to overcharging.
