Heating, Ventilation, Air Conditioning, Refrigeration Program Overview

  • Request work from Diman's HVAC/R Program

    The Heating, Ventilation, Air Conditioning, and Refrigeration program has been designed to prepare students for immediate employment in the heating, ventilation, air conditioning and refrigeration industries. Upon completion of this program, students possess the necessary knowledge, skills and certifications to diagnose, repair and install today's equipment. Our instructors work to instill 21st Century Skills and social responsibility in all students, and highlight areas of our trade that effect sustainability and environmental impact.  The HVACR shop believes that a diverse workforce will help strengthen the industry of the future, and create a positive learning environment for everyone. 

    The Heating, Ventilation, Air Conditioning, and Refrigeration program is one of the licensed mechanical trades here at Diman, and the only trade where students are immediately able to enter the industry after graduation, without the need for continuing education or night schooling.  Students will earn the Environmental Protection Agency (EPA) 608 Certification which allows work on most air conditioning and refrigeration equipment found in most residential and light commercial properties.  Upon completion of the four-year program at Diman and being eighteen years of age, new technicians should register with the Massachusetts Division of Apprentice Standards (DAS) and for their Refrigeration Apprentice License from the Massachusetts Bureau of Pipefitters, Refrigeration Technicians, and Sprinkler Fitters.  After 2000 hours of on-the-job-training (OJT) and proper registration, technicians will be allowed to test for the Massachusetts Refrigeration Technician license which permits unrestricted large commercial work.  This license is transferable to other states that currently have articulation agreements.
