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. 

Though the scope and range of the industry has grown exponentially since then, RSES has remained dedicated to delivering technical information to HVACR professionals under a single vision and mission:

Vision Statement
To be the definitive industry leader in all segments of the HVACR industry by providing superior educational training.

Mission Statement
To provide opportunities for enhanced technical competence by offering comprehensive, cutting-edge education and certification to our members and the HVACR industry.  To advance the professionalism and proficiency of our industry through alliances with other HVACR associations.

RSES, a 501(c)(6) membership organization with members in chapters in the U.S. and Canada, with additional technicians routinely using its training material in 50 countries across six continents.
