Refrigeration technicians work in workshops, building sites, factories, manufacturing shops, and customers' houses. They often work alone; though larger building projects usually employ a team of 3–5 refrigeration technicians. An independent job entails that the technicians must acquire a broad set of skills. They must be able to understand installation specifications and plans and choose the best implementation method. A good result requires creative thinking.

Refrigeration technicians install several components which form the refrigeration system. This includes soldering pipes and the safe handling of refrigerants without causing danger to the environment. They are skilled in electronics and understand airflow techniques. Interpersonal skills are also needed since the technicians must be able to work with a variety of people.
