Additional Course Materials:

Textbook: Fundamentals of HVACR

Learning Aid: Troubleshooting Guide for Compressors

The work performed by HVACR technicians is diverse and involves different applications of the fundamental concepts you’ve studied. The work also includes a wide range of air conditioning and refrigeration systems. This part of your program explains how those systems work and describes the major components, as well as the accessories used for the proper operation of systems with specific designs. This course discusses the many kinds of components you’ll encounter when servicing various types of refrigeration systems and what makes one type better suited for an installation than another. You’ll learn how to display good work practices, demonstrate care for the environment, and follow the law when handling refrigerants. Finally, this course discusses system servicing, evacuation, and charging.

Objectives:

  • Categorize the different refrigeration systems and their parts
  • Distinguish among refrigeration devices, components, refrigerant properties, and the safety measures associated with each
  • Describe the servicing, testing, and maintaining procedures for refrigerant systems
The ability to troubleshoot heating, ventilation, air conditioning, and refrigeration (HVACR) equipment electrical problems is an important aspect of the HVACR technician’s role. Troubleshooting involves reading schematic and pictorial diagrams, interpreting the information to isolate the problem and conduct the appropriate tests, and then replacing the correct component. To be effective in achieving the ultimate goal of correct diagnosis, you’ll need a firm grasp of electrical safety, basic electricity, and the proper use of test instruments.

Objectives:

  • Explain electrical power and the operating characteristics of equipment, circuits, motors, and control devices
  • Use schematics to determine the expected operation of an electrical system
In this course, you’ll describe how air-conditioning and heating systems are installed and serviced in residential and smaller commercial applications. You’ll also receive practical tips and instructions.

Objectives:

  • Identify the fundamentals of psychometrics and the various functions of air filters and ventilation systems
  • Distinguish the various operations, installation processes, and troubleshooting of refrigeration systems and air-conditioning systems
  • Analyze the principles, functions, and safety measures involved in combustion, gas, and oil heating systems
  • Categorize the various applications and troubleshoots of electric heating systems and heat pump systems
In this course, you’ll explore how heating, ventilation, air conditioning, and refrigeration (HVACR) play a huge role in designing residential and commercial spaces. You’ll study how HVACR is an integral part of all buildings and how taking into account issues like indoor air quality, duct design, and load calculations help make buildings a safer place to live and work. You’ll also discover the air conditioners, fans, and various systems and equipment that are in commercial buildings.

Objectives:

  • Describe the components, calculations, and designed associated with building constructions and systems
  • Analyze the methods of duct designing and the systems of zone controlling and air balancing
  • Identify the components and purpose of air-conditioning, commercial control, chilled-water, and air-handling systems
  • Distinguish among the types, components, and operating processes of chilled-water and hydronic heating systems
This course focuses on refrigeration systems related to food preservation and processing, including ice machines. It provides a more general guide to the types of troubleshooting, installation, and maintenance work carried out by heating, ventilation, air conditioning, and refrigeration (HVACR) technicians every day.

Objectives:

  • Analyze operations and troubleshooting related to supermarket refrigeration systems and ice machine equipment
  • Identify the various troubleshoots concerning commercial refrigeration systems
  • Categorize the major phases of installation, maintenance, and cleanup procedures in refrigeration systems
