Syllabus

Introduction to Heating Motors

This module provides a detailed walkthrough of high-efficiency gas furnace anatomy, highlighting the physical location and purpose of critical internal components. It covers the air path from the return duct through the filtering system and blower, into the combustion and heat exchange phases. Technicians will gain a clear understanding of how the inducer motor, gas valve, and dual heat exchangers work in tandem to provide heat while maximizing fuel efficiency.

Gas Heating Parts

This module introduces the manifold gauge set, the most essential tool for diagnosing and servicing refrigeration systems. It provides a detailed breakdown of the gauge's physical components, including the color-coded hoses and high/low-side valves. Technicians will learn how to accurately interpret pressure readings and use the integrated temperature scales to evaluate system performance.

Hydronics

This module breaks down the fundamental components and physical layout of a standard split-system air conditioner. It explains how the system removes heat from the home through the evaporator coil and rejects it outside via the condensing unit. Additionally, the module covers the vital role of the air handler and filtration system in maintaining airflow and indoor air quality throughout the cooling cycle.

Electrical and Safety Controls

This module provides an in-depth examination of the outdoor condensing unit, focusing on both its structural design and internal mechanical operations. It details how the compressor and condenser fan motor work together to dissipate heat from the high-pressure refrigerant into the outside environment. Additionally, the module covers the electrical enclosure, explaining the critical roles that capacitors and contactors play in starting and regulating the system’s high-voltage components.
