Every HVAC system runs on electricity. A technician without strong electrical fundamentals wastes time, replaces good parts, and creates safety hazards. This course builds your electrical knowledge from the ground up - from Ohm's Law to systematic troubleshooting - in 7 structured modules with real-world HVAC applications on every concept.
Any HVAC technician at any experience level who wants to troubleshoot faster, diagnose more accurately, and understand why things work the way they do. Also essential prep for the NATE Core exam and EPA exams where electrical knowledge is tested.
