HVAC 3 continues the progression of technical training by expanding on prior coursework with a focus on system diagnostics and advanced applications. Modules include fasteners, hardware, and wiring terminations; troubleshooting of control circuits, motors, cooling systems, heat pumps, gas and oil heating systems, and accessories; as well as zoning, ductless and variable refrigerant flow (VRF) systems, commercial hydronic and steam systems, retail refrigeration systems, and customer service practices. This course is part of a comprehensive four-level HVAC apprenticeship program that meets DOLI standards and is recognized by North American Technician Excellence (NATE).
