Instruction Set 4

Refrigeration Systems
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.

Instruction Set 5

Electrical 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.

Instruction Set 6

Residential and Light Commercial HVACR
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.

Instruction Set 7

HVACR System Design and Installation
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.

Instruction Set 8

Commercial Refrigeration 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.


Online Library and Librarian
Students in Penn Foster College have access to an online library for use during their studies. Students can use this library to do the required research in the courses they complete or can use it for general reference and links to valuable resources. The library contains helpful research assistance, articles, databases, books, and Web links. A librarian is available to answer questions on general research-related topics via email and to assist students in research activities during their studies with Penn Foster College International.
