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.

This course is a primer on lockout/tagout procedures. The course begins with the definition and purpose of lockout/tagout procedures, followed by employee roles during lockout/tagout. A discussion of hazardous energies is included, specifically primary, secondary, single, and multiple energy sources, with an emphasis on identifying all energy sources during lockout/tagout procedures. The course concludes with eight practical steps for an effective lockout/tagout program.

This course is designed to increase learners’ awareness of the lockout/tagout energy control procedure. Main topics of instruction include an outline of regulatory lockout/tagout procedures, applicable definitions and terminology, and an overview of standard tools and devices. In addition to instructional lessons, this course contains a simulation video demonstrating the implementation and removal of lockout/tagout devices.

This course will cover the impact low global warming potential refrigerants are having on the HVAC landscape. Learners will explore the history of refrigerants and come to understand their chemical composition and safety characteristics. They will also be able to recall best practices for working with A2L refrigerants. Finally, learners will be able to recall the tools, safety, code, and regulations involved in working with refrigerants. This course was developed in collaboration with NATE.

This Make Ready Course will provide you with the structure and procedures to perform a make ready inspection. The course begins with an overview of the clipboard and important information about the apartment itself. Next, you will see a video walkthrough for each room that goes through the various procedures and input fields in which record your results. After the videos you will engage in six separate training inspection simulations where you will traverse the apartment room by room, marking the condition of different components and fixtures within the unit. Finally, the training wheels are taken off and you will complete six randomly generated inspections with less help from the procedures and clipboard.

In this course, we will explore how Manual D protocols are used for calculating and designing HVAC systems in residential buildings. Manual D is the industry standard protocol for calculating the size required for return and supply ducts and registers. You will learn how HVAC technicians use the Manual D protocols to calculate duct and register requirements to ensure the appropriate distribution of heating and cooling to each area in a designated space.

In this course we will explore how Manual J protocols are used for calculating and designing HVAC systems in residential buildings. Manual J is the industry standard protocol for calculating heating and cooling loads. You will learn how HVAC technicians calculate and use the Manual J heating and cooling load results to select the appropriate HVAC equipment capacity.

In this course you’ll learn the fundamental math skills used in the electrical field. It covers symbols, units, followed by transposing formulas and solving equations using Ohm’s Law and Kirchhoff’s Law. You’ll also learn how geometry and trigonometry are used in the industry.

In Mechanical Commissioning, we will conduct a final inspection of a solar installation, before performing electrical commissioning. This inspection will confirm that all mechanical components are installed safely, and labeled properly.

The Metering Device course explores the multitude of regulating valves in an HVAC system. The thermostatic expansion valve (TEV) will be introduced and you will learn how it adjusts to maintain superheat. You will be able to identify valve types, discover how they are fitted to a pipe, and the differences in external and internal pressure equalization. Discover TEV bulbs and their roles in regulating superheat within the system, along with proper placement and methods for installation. Learn the unique model codes for some common manufacturers and the functions of several different kinds of metering devices.
