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

Associate Degree


HVAC/R is one of the fastest growing industries in the world today. With the changing laws involving refrigerants and the influx of digital control systems, there is a constant need for qualified service technicians to work on HVAC/R equipment. A service technician will have to continually update his/her skills to keep up with the changing industry.

This program will provide proper training for people interested in a career in the heating, ventilation, air conditioning and refrigeration (HVAC/R) field. The technician will be prepared for employment in a variety of areas including servicing, installing, designing, estimating and selling HVAC systems for commercial and residential applications. The most modern equipment, test instruments, and computers are used for instruction.

After completing the HVAC/R two year associates degree program, students may wish to pursue additional training in heating, ventilation, and air conditioning engineering. Credit for many of the associate degree courses in the program may be transferred to a four-year institution.

  • Perform HVAC/R service and repair operations in compliance with published safety standards.
  • Promote customer satisfaction.
  • Operate tools/equipment according to process published in operator’s manual and/or demonstrated in class.
  • Service and/or repair/replace defective components established in equipment specific repair manual and/or electronic service information systems.
  • Diagnose root cause of problems by comparing test results to an established standard.
  • Efficiently complete tasks within the expected time frame for an entry level technician.
