An undercharged or overcharged refrigerant system can lead to reduced efficiency, increased energy bills, and potential damage to the system’s components. Undercharging can cause reduced cooling capacity, increased compressor pressure, and overheating, while overcharging can lead to liquid refrigerant flooding back to the compressor, causing damage to the compressor valves and bearings. Additionally, an improperly charged system can also lead to increased emissions, noise, and vibration. Regular refrigerant charge verification is essential to prevent these issues and ensure optimal system operation.
