Conquer the Journeyman HVAC Exam in Under 90 Minutes: Study Guide for Warm Air Heating, Ventilation Systems, Air Conditioning Systems, Ducts, Chimneys, Boilers, Piping, Combustion Air and Refrigerants

By: Philip Martin McCaulay

Narrated by: Virtual Voice

This concise study guide delivers a focused technical review of journeyman-level HVAC systems, covering the core mechanical concepts found across warm air heating, ventilation, air conditioning, and hydronic applications. It explains how HVAC systems function as integrated assemblies rather than isolated components, emphasizing airflow behavior, heat transfer, combustion principles, and system interaction. The material is structured for efficient listening, making it well suited for audio study and rapid review.

Coverage includes furnaces, boilers, air conditioning systems, ductwork, chimneys, venting, fuel delivery, controls, insulation, and refrigerant fundamentals. Each topic is presented with clear technical explanations that prioritize system behavior and operational logic. The content avoids unnecessary theory while preserving the depth needed to understand how HVAC systems perform under real operating conditions.

Special attention is given to areas often tested at the journeyman level, including combustion air, ventilation pressure relationships, refrigerant piping integrity, hydronic circulation, and commercial kitchen exhaust systems. The guide also addresses chilled and condenser water piping and firestopping considerations, reflecting the broader mechanical knowledge expected of licensed HVAC professionals.

Designed as an efficient refresher rather than an exhaustive textbook, this guide supports tradespeople who already work with HVAC systems and want a structured, audio-friendly technical review. If you’ve already invested time and money into preparing, don’t leave success to chance. This quick, focused review is here to help you pass the first time.
