About the Course:

This Packaged Rooftop Unit (RTU) Fundamentals microcredential trains HVAC associates to understand, operate, inspect, and safely maintain packaged rooftop units (RTUs) commonly used in commercial and light industrial environments. Learners will explore key RTU components, including compressors, condensers, evaporators, fans, filters, dampers, electrical controls, and thermostats, while practicing essential inspection and service procedures. 

The course emphasizes safe startup and shutdown, component identification, system inspection, basic troubleshooting, and preventive maintenance. Through immersive training, learners develop the practical skills needed to support reliable RTU operation, identify common issues, and perform service tasks safely and efficiently. 

 

Learning Objectives:

  • Identify the major components and functions of a packaged rooftop unit 
  • Understand the basic operation and airflow cycle of an RTU 
  • Inspect RTU components for damage, wear, contamination, and abnormal conditions 
  • Perform safe startup, shutdown, and operational checks 
  • Identify common electrical, mechanical, airflow, and refrigeration-related issues 
  • Perform basic preventive maintenance tasks, including filter and component inspections 
  • Verify proper airflow, temperature operation, and overall system condition 
  • Document inspection findings and report issues requiring further service 

Course delivered through our LMS and accessible in both VR and web. Learn on the web anytime, or enjoy immersive VR training with your own Oculus VR headset.

Workforce Development

HVAC hand tool identification and safe tool selection

At ImmerseLearn, we equip HVAC associates with hands-on, job-ready skills required for safe and effective packaged RTU operation and maintenance. This microcredential strengthens RTU component identification, inspection, operation, troubleshooting, preventive maintenance, and workplace safety through immersive VR practice. 

How this course strengthens workforce skills: 

RTU Components and System Identification −
Learn to identify major packaged RTU components, including compressors, condenser coils, evaporator coils, supply and return fans, filters, dampers, thermostats, electrical controls, and safety devices. Learners explore how these components work together to provide conditioned air and maintain comfortable indoor environments.
RTU Operation and Inspection +
Practice performing basic RTU startup, shutdown, and operational checks. Learners inspect equipment condition, airflow, filters, coils, fans, electrical connections, and other accessible components while recognizing signs of abnormal operation, damage, or reduced performance.
RTU Safety and Hazard Identification +
Recognize hazards associated with rooftop equipment, electrical systems, rotating components, hot and cold surfaces, elevated work areas, and moving machinery. Learners apply appropriate PPE, follow lockout/tagout principles where required, and maintain safe work practices during RTU inspection and service activities.
Preventive Maintenance and Troubleshooting +
Perform basic preventive maintenance activities designed to support reliable RTU operation. Learners practice checking filters, coils, fans, belts, electrical components, and other serviceable areas while identifying common operational issues and determining when additional troubleshooting or qualified service is required.

By completing this microcredential, HVAC associates will develop the confidence and practical skills needed to identify, operate, inspect, maintain, and safely service packaged rooftop units, supporting efficient, reliable, and professional HVAC operations.
