Step into a trade with steady demand and hands-on problem solving. This free online course is designed to help you build practical, job-ready skills for working with refrigeration and air conditioning systems, whether you are starting from scratch, reskilling, or looking to sharpen what you already know. You will gain confidence with the everyday tasks technicians face in installations, maintenance, and service calls, focusing on the techniques that keep systems efficient, reliable, and safe.
You will begin by understanding how to choose and use essential tools correctly, then move into copper tube handling that supports clean, professional work. The course guides you through creating durable pipework, forming and bending copper accurately, and making secure connections across common joining methods. Along the way, you will learn habits that reduce call-backs, such as careful preparation, proper fit-up, and attention to finishing details that protect system integrity over time.
A major part of quality HVAC/R work is preventing and finding leaks. You will learn how to detect leaks using practical methods that work in real environments, building a mindset for verification before you proceed to the next step. From there, you will develop an understanding of the preparation steps that protect equipment and performance, including proper evacuation practices and the importance of accurate refrigerant charging. You will also cover recovery procedures that support responsible servicing and better compliance in the field.
To support real-world servicing, the course helps you get comfortable connecting a RAC unit to a manifold gauge and interpreting what the setup is telling you. You will also learn why thermal insulation matters, how good cable preparation supports reliable operation, and how careful handling, transport, and storage practices reduce risk and damage on the job.
Finally, you will build safety awareness for working with flammable refrigerants and hydrocarbon refrigeration systems. You will learn to approach these jobs with preparation, the right specialist equipment, and an understanding of safety features designed to protect people and property. By the end, you will be better equipped to work confidently, follow safe practices, and communicate professionally in a refrigeration and air conditioning technician role.
