About the Course:

This Air-Cooled Chiller Maintenance microcredential trains HVAC technicians to safely inspect, clean, maintain, and verify the operation of air-cooled chiller systems. Learners will practice essential maintenance procedures, including electrical shutdown and lockout, component inspection, condenser coil cleaning, fan inspection, compressor checks, sensor inspection, and system restart. 

This air-cooled chiller maintenance training helps technicians strengthen practical skills in HVAC preventive maintenance, component inspection, and system verification.

Through immersive VR simulations, learners gain hands-on experience identifying signs of damage, leaks, dirt buildup, loose connections, and abnormal component conditions. The course emphasizes electrical safety, proper lockout/tagout procedures, equipment inspection, preventive maintenance, and safe system restoration. 

Learners can also strengthen their condenser coil cleaning skills through focused maintenance training.

Learning Objectives:

The course supports technicians performing routine HVAC chiller maintenance and preventive maintenance procedures.

  • Perform safe chiller shutdown, electrical isolation, and lockout procedures. 
  • Inspect the chiller for damage, leaks, loose components, and abnormal conditions. 
  • Inspect and clean condenser coils using appropriate tools and methods. 
  • Check condenser fan blades and assemblies for damage, dirt, or obstructions. 
  • Inspect the expansion valve and verify proper operation. 
  • Inspect compressor wiring, electrical connections, physical condition, and vibration. 
  • Inspect temperature sensors and verify secure connections. 
  • Clean and inspect temperature and pressure meters. 
  • Safely restore electrical power and restart the chiller after maintenance. 
  • Follow appropriate PPE, electrical safety, and workplace maintenance procedures.

Air-cooled chiller maintenance training for HVAC technicians

 

Workforce Development

HVAC technician performing air-cooled chiller maintenance

At ImmerseLearn, we equip HVAC technicians with hands-on, job-ready skills required for safe and effective chiller maintenance. This microcredential strengthens electrical safety, preventive maintenance, component inspection, cleaning, troubleshooting awareness, and system verification through immersive VR practice. 

These skills support technicians responsible for air-cooled chiller preventive maintenance, condenser maintenance, compressor inspection, and HVAC system verification.

How this course strengthens workforce skills:

Electrical Shutdown and Lockout −
Practice safely stopping the chiller, disconnecting the power supply, securing the electrical disconnect, and applying a lockout device before beginning maintenance. Learners reinforce proper electrical safety procedures to prevent accidental energization during service.
Chiller Inspection and Condenser Coil Maintenance +
Inspect the chiller interior for visible damage, leaks, loose components, and refrigerant-related issues. Learners practice inspecting condenser coils for dirt and debris, cleaning them using approved methods, and verifying that the coils are clean and unobstructed.
Condenser Fan and Component Inspection +
Practice inspecting condenser fan blades and assemblies for damage, excessive dirt, resistance, or obstructions. Learners also examine the expansion valve and other accessible components to identify conditions that may affect system performance.
Compressor and Sensor Inspection +
Inspect compressor wiring, electrical connections, physical condition, and vibration. Learners practice checking temperature sensor connections and cleaning temperature and pressure meters to support accurate system monitoring.
Power Restoration and System Verification +
Learn to safely remove the lockout device, restore electrical power, and restart the chiller following maintenance. Learners verify that the system is ready for operation and reinforce safe completion of maintenance procedures.

By completing this microcredential, HVAC technicians will develop the practical skills needed to safely inspect, clean, maintain, and restore air-cooled chillers, supporting reliable system performance, preventive maintenance, and safe HVAC service operations.
