In this intermediate course on High Efficiency Boiler Troubleshooting, we will explore the troubleshooting tasks of the high efficiency boiler system. With each scenario, you will be guided with realistic steps of interaction to complete the procedures for how to inspect defects and faults through measurements from different error codes.

This is an assessment simulation, where you'll use the steps and skills you've learned and practiced on the Interplay platform to determine the fault and fix each scenario. Use the bottom tool bar to navigate around the environment, inspect components, access tools, and view diagrams. This is designed to mimic a real-world scenario, so there's no step by step guide giving you instructions for how to troubleshoot the scenario.

Welding, brazing, and other work that can create sparks are a fire hazard. In this course, you will learn about the hazards, safety precautions, responsibilities, and emergency procedures associated with hot work.

Knowing the basics of how plumbing works is essential in order to understand the more complicated topics. In this course, you'll discover the two different plumbing systems, how they work, and how they're set up in a building. You'll also learn about the "why" behind the design of these systems, which will help you to grasp more advanced topics later on. This is a great introductory course to get you started with plumbing!

A multimeter is an important tool for troubleshooting and measuring the overall performance of an electrical circuit or machine. It is designed to combine several different electrical meters all into one tool. This course covers each of the common settings on a multimeter such as voltage, resistance, amperage, diodes, and capacitance. It includes video demonstrations from your instructor Tim Smith and a virtual lab simulation where you can use a multimeter to test your skills.

Learn about the ventilation parts of an HVAC system. This course covers the ductwork, fans, grilles, and registers used to create proper airflow in a house. This is a beginner's course that focuses on the materials that make up the ventilation system and improve indoor air quality.

A well-maintained HVAC system ensures peak efficiency. Annual maintenance such as cleaning, voltage checks, condensate removal, and burner inspections are required to achieve maximum efficiency and avoid major issues. This course covers the maintenance needed on air conditioning systems and heating systems, both forced air and hydronic.

An introduction to motors used in residential and commercial settings. Learn about shaded pole motors, split phase motors, and three phase motors. This course also includes a section on the popular permanent split capacitor motor or PSC.

Always work with a safety first mindset! In the HVAC field you will encounter high voltage electricity, combustible gases, metal fabrication, and ladders. This course covers HVAC best practices and procedures on fire safety, personal protective equipment, ladder usage, electrical circuits, and shock risk, as well as, Lockout/Tagout procedures.

This course covers the things that aren't considered major parts but play a major role. It explores different kinds of thermostats, what a condensate pump does, common installation supplies, and the materials needed to braze line sets. This is a great course for understanding the little things that make up a whole HVAC system.
