In this course, you’ll learn system operations and the basic practices for maintenance and troubleshooting of air-conditioning and refrigeration systems, and the law for handling refrigerants.

Instruction Set 5

Electrical Systems
This course will provide you with an understanding of electrical power and the operating characteristics of equipment, circuits, motors, and control devices. You’ll use schematics to determine the expected operation of an electrical system, connect circuit components, evaluate systems to identify problems, and determine a process you can follow to solve the problems you identify.

Instruction Set 6

Residential and Light Commercial HVACR Systems
In this course, you’ll learn how air-conditioning and heating systems are installed and serviced in residential and smaller commercial applications, and receive practical tips and instructions.

Instruction Set 7

HVACR System Design and Installation
This course will teach you about building and duct design and HVACR system placement. You’ll explore the skills required to properly install an air distribution system, and learn about commercial-scale hydronic heating systems and the boilers that serve as their heat source, and identify common problems with these systems.

Instruction Set 8

Commercial Refrigeration and HVACR Maintenance
Learn how to identify components used in commercial refrigeration systems, and gain an understanding of the three categories of “everyday tasks” you’ll encounter while working in the field: installation, maintenance, and troubleshooting.

Lithium Bromide Absorption Systems
In this course, you’ll learn what absorption refrigeration is and how lithium bromide acts as the absorbent, and the recommended operation and maintenance of a lithium bromide absorption unit.
