In the Meters, Circuits, Loads and Switches course you will learn how to use four of the most common meters in HVAC today: the voltmeter, ohmmeter, ammeter, and multimeter. You will discover why safety controls are wired in series, and why most loads are wired in parallel. As well as, how to measure and calculate volts, ohms, and amperage and how to use these values to troubleshoot a system.

In this course on microwaves, we'll start off learning to identify the various components of a microwave. You’ll learn about the function of each component and how they all work together. After that we’ll look at the different configurations and installation styles, including countertop, built-in, over the range, and a few more. Then we’ll finish up the course looking at the different cooking operations microwaves can perform and how they work.

This course explores the common faults within the mini split heat pump such as faulty sensors, faulty motors, as well as communication system faults. This is a fun, interactive and effective way to learn how to fix the faults within the mini split heat pump system.

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 short course focuses on fundamental job skills and knowledge including components, tools, measurements, heat transfer, general safety and electrical safety. This course is designed for technicians who are just entering the HVAC field with little to no formal education or training. It's a great course to get started.

In this course on NEC Commissioning - Rough-in Inspection, we will explore the process of electrical rough-in inspection for multiple rooms in a residential home. With each scenario, you will be guided with simulation based steps to check key visuals and measurements for electrical inspection. You will also be referring to articles of code from the 2020 edition of the NFPA 70® National Electrical Code.

In this course, we’re going to be exploring the 2020 version of NFPA 70, National Electrical Code®. We will focus on a broad understanding of the material, so you can access and reference the codebook more easily when needed. As a whole, NFPA 70 consists of a total of nine chapters, but not all apply to residential applications. Chapters one through four apply generally to all electrical installations, including Methods and Materials in Chapter 3. The NEC goes over specific areas for types of wires and where they are acceptable to be installed, and how they should be installed and protected from environmental and physical damage. We will cover the most impactful sections of the chapter, including conductors and cables, cabinets, cutout boxes and meter socket enclosures; outlet, device, pull, and junction boxes; conduit bodies, fittings, and handhole enclosures, as well as various types of cables and other wiring installations that may apply to residential applications, and some commercial and urban applications, as well.

Packaged refrigeration unit (PRU) servicing requires primary knowledge of refrigeration and unit operation. This introductory course will help you gain, or refresh, that essential knowledge. We will begin with the standard features of a PRU and the uses of each type. Then we will examine each of the PRU components and how they operate together. Last, we will go through a basic inspection process and some common issues you will find.

In this series of simulations, you'll gain valuable experience when it comes to preventive maintenance on packaged refrigeration units. These procedures will ensure long equipment life, energy efficiency, as well as proper system performance. You'll have an opportunity to perform cleaning procedures, system performance checks, both electrical and temperatures and pressures, as well as leak detection. This course will get you thinking and acting like a pro when it comes to maintenance on packaged refrigeration units.

Apply your knowledge of Packaged Refrigeration Units (PRUs) in this course as you inspect, diagnose, and repair PRUs within a 3D simulation program. These simulations will demonstrate what you’d experience when encountering the 10 most common PRU failures. We’ll also cover the safety risks involved and important measures you must take to avoid them.
