DES PLAINES, IL — The Educational Foundation of the Refrigeration Service Engineers Society (RSES) recently expanded its National Technician Certification (NTC) program to a total of nine certification categories.
The new categories of certification include gas heating, hot water heating, and steam heating. In addition, the foundation separated the formerly combined refrigeration and air conditioning category into two individual categories. The categories of heat pump service technician, heat pump installer, and heat pump designer-estimator remain unchanged.
