Residential and Light-Commercial Electrical and HVAC Essentials

Residential and Light-Commercial Electrical and HVAC Essentials

This 20-hour online training covers electrical fundamentals, motor troubleshooting, refrigeration diagnostics, and installation practices for residential and light-commercial systems.

Why HVAC technicians need electrical and HVAC essentials training

HVAC technicians troubleshoot systems that fail because of electrical faults, refrigerant issues, airflow problems, or motor failures. Diagnosing these problems requires understanding electrical circuits, multimeter readings, refrigeration cycles, and motor controls. Contractors need technicians who can trace a problem from symptom to cause without calling for backup.
