- Point out the scientific elements and laws associated with HVACR
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.

By the end of this course, you’ll be able to do the following:
- 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 the fundamental concepts of electrical safety, basic electricity, and the proper use of test instruments.

By the end of this course, you’ll be able to do the following:
- 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.

By the end of this course, you’ll be able to do the following:
- 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
