This May's Coupon Code — 20% Rses

Since 1933 Rses has been a leader in the training and education of HVACR professional technicians and contractors. They were initiated at a time when the small commercial and domestic refrigeration industry was in its infancy. At that time, the only training was through the factory and usually lasted three to four weeks. Those who completed the factory training are now considered "factory trained specialists". Most work was performed by product dealers and distributors or factory service departments. With the increase in installation work and the need for independent service personnel, the need to collect, distribute and exchange ideas and information has become very important. It was through the tireless efforts of these independent service operators Rses was born. They have become the absolute industry leader in all areas of the HVACR industry by providing superior education and training.
