HVAC-R Appliance Technology

Greater New Bedford Regional Vocational Technical High School


The HVAC-R Appliance (heating, ventilation, air conditioning, refrigeration, and appliance technology) industry is one of the faster growing, high-paying career paths an individual could choose. Every building today has some type of climate control system and over 80% of residential homes being built have central air conditioning systems and electronic/computerized appliance equipment installed. Commercial buildings (hotels, restaurants, hospitals, and high-rise buildings) all use modern EMS (Energy Management Systems) to efficiently operate their facilities.

There are a variety of career paths a graduate of this area can pursue, which include but are not limited to: licensed refrigeration tech, HVAC-R Appliance installer (dust system and sheet metal). Electrical control wiring, oil burner, gas heating technician, or residential/commercial appliance service technician. Upon further education, options include a career as a mechanical engineer, building superintendent, or self-employment. Opportunities are endless in this exciting and rewarding career, and lucrative employment is available worldwide. Upon enrollment, students are taught the trade and safety basics and the use of specialty trade-related equipment and analyzers. Their study continues on into trade-related theory that covers electricity and control wiring, refrigeration, air conditioning, gas and oil fired heating equipment, and appliance technology.

Junior and senior year students’ curricula includes commercial systems and being involved in the school’s off-campus construction program, where students get involved in community projects related to their trade. The State of Massachusetts requires a refrigeration technician’s license to work on and to operate machines that are rated at 120,000 BTU or larger. The EPA (Environmental Protection Agency) requires persons who handle refrigerants to be certified. Students majoring in the program at GNB Voc Tech are able to achieve this certification before graduation. Related classes and shop/lab hours can be applied to trade licensure requirements.
