The need for heating, air-conditioning, and refrigeration exists all over. Cooling and heating devices help regulate the temperature, humidity, and air quality in residential homes, commercial locations, and industrial facilities. Many items like food and medicine require refrigeration to keep them from spoiling. Technicians carry out repairs, maintenance, and installations of heating, air-conditioning, and refrigeration systems. As these systems are often called HVACR systems, workers are often referred to as HVACR technicians.
Frequently technicians will pick an area of specialization, be it in installation or maintenance and repair, though they are typically trained in both areas. A few technicians work solely with one type of device such as an oil burner, solar panel, or commercial refrigerator. Contracting businesses, manufacturers, and wholesalers often employ technicians. Technicians employed by smaller companies often install and maintain all types of systems.
