Heating, Ventilation, Air Conditioning and Refrigeration (HVAC/R)

Students receive hands-on shop training to prepare them for the actual service and installation procedures that will be required of them in the field. Such technicians use a variety of hand and power tools to make repairs or adjustments. In addition, electrical problems require knowledge of electrical diagnostic meters and tools. In depth, theoretical classroom training leads to developing diagnostic skills and an understanding of terminology and specifications as well as relevant articles of the Massachusetts State Building Code as well as other mechanical codes.

Heating, Ventilation, Air Conditioning, and Refrigeration (HVAC/R) is a field that is essential to our modem technological society. HVAC/R technicians install, maintain, and repair various units that keep us warm in the winter, cool in the summer and maintain an indoor environment for business and industry that keeps workers’ productivity at its peak and makes possible for many precise manufacturing processes.
