About the Course:

This Boiler Maintenance microcredential trains HVAC technicians to safely inspect, maintain, and verify the performance of commercial boiler systems. Learners practice isolating gas and electrical supplies, servicing air filtration components, cleaning and inspecting ignition system parts, measuring electrode gaps, and performing gas pressure verification using a manometer. The course emphasizes preventive maintenance, safe work practices, proper component reinstallation, and performance testing to ensure efficient, reliable, and safe boiler operation.

Learners seeking a foundational overview of boiler systems and components can explore our Boiler Introduction microcredential.

Learning Objectives:

  • Safely isolate gas and electrical power before servicing the boiler  
  • Inspect, clean, and replace boiler air filter and foam pre-filter components  
  • Remove, inspect, clean, and reinstall ignition system components   
  • Measure and adjust the electrode gap to manufacturer specifications  
  • Reassemble boiler components using proper tools and procedures   
  • Perform gas pressure testing using a manometer  
  • Verify proper boiler startup and confirm operating pressure is within specification  
  • Apply preventive maintenance practices to improve boiler reliability and efficiency

Workforce Development

Boiler maintenance training for HVAC technicians

At ImmerseLearn, we equip HVAC technicians with hands-on, job-ready skills required for maintaining commercial boiler systems. This microcredential strengthens preventive maintenance, equipment inspection, troubleshooting, system testing, and safety compliance through immersive VR practice. 

How this course strengthens workforce skills:

Boiler Inspection and Preventive Maintenance −
Learn how to safely prepare a boiler for maintenance by isolating gas and electrical supplies, accessing internal components, and inspecting air filtration systems. This training helps technicians identify maintenance requirements before they affect system performance or reliability.
Air Filter and Ignition System Servicing +
Practice removing, cleaning, inspecting, and reinstalling boiler air filters, foam pre-filters, flame sensors, igniter injectors, O₂ sensors, and ignition electrodes. Learners use proper maintenance techniques, verify electrode gap specifications, and ensure components are correctly reassembled for reliable ignition performance.
System Diagnostics and Performance Verification +
Develop the skills to identify common maintenance issues such as dirty filters, worn ignition components, improper electrode gaps, and combustion-related performance concerns. Learners understand how preventive maintenance improves combustion efficiency, equipment lifespan, and overall system reliability.
Gas Pressure Testing and Operational Verification +
Perform boiler startup procedures, connect a manometer to the pressure test port, measure gas pressure, and verify readings against manufacturer specifications. Learners complete the maintenance process by confirming proper system operation, combustion performance, and safe boiler functionality.

By completing this microcredential, HVAC technicians will develop the confidence and technical skills needed to perform routine boiler maintenance, improve system efficiency, ensure safe operation, and maintain reliable heating performance in real-world service environments.

Learners seeking broader skills in system diagnostics, advanced troubleshooting, repair, and installation can explore our advanced HVAC Technician training program.
