Since 1933, Refrigeration Service Engineers Society (RSES) has been a leader in training and education for professional HVACR technicians and contractors. RSES was launched in an era when the small commercial and domestic refrigeration industry was in its infancy. At that time the only training available was through the factory and it typically lasted three or four weeks. Those who completed the factory training were now considered a “factory-trained expert.” The majority of work was conducted by product dealers, distributors, or factory service departments. As more installations were done the need for independent service operators increased and the need for collecting, distributing, and exchanging ideas and information became paramount. It was through the untiring efforts of these independent service operators that RSES was born.
