Common Air-Cooled Chiller Problems We Diagnose & Fix

Insufficient Cooling or Fluctuating Temperatures

• Chiller fails to reach or maintain set temperature
• Uneven cooling due to airflow restrictions, clogged coils, or refrigerant issues

High Energy Consumption & Overworked Compressor

• Increased power bills due to inefficient chiller operation
• Compressor running continuously or cycling excessively

Refrigerant Leaks & Pressure Imbalances

• Low refrigerant charge causing inefficient heat absorption
• High or low suction/discharge pressures leading to compressor strain

Electrical & Sensor Malfunctions

• Frequent tripping, wiring faults, or control system failures
• Inaccurate sensor readings affecting temperature and pressure regulation

Unusual Noises & Vibrations

• Rattling, grinding, or knocking sounds from motors, fans, or compressors
• Excessive vibration due to misalignment or worn-out bearings

Frozen Evaporator Coils or Excessive Condensation

• Ice buildup due to low refrigerant, restricted airflow, or improper expansion valve function
• Condensate drain blockages causing water pooling and system inefficiencies
