Heating, Ventilation, Air Conditioning, & Refrigeration
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.
