Auburn Hills Campus

This program leads to an associate in applied science degree with specialization in Heating, Ventilation, Air Conditioning and Refrigeration. It is designated as an extended degree because the student must complete a minimum of 73 or more required credit hours. Program graduates are encouraged to transfer to a four-year college or university to complete their education in Engineering Technology or Energy Management. However, program graduates may qualify for occupations and careers in heating, ventilating and air conditioning such as systems designers, technicians, estimators, sales engineers and manufacturers’ representatives.

High school graduates who completed state-approved career and technical education (CTE) programs may be eligible to receive college credit for work completed while in high school.  Detailed information can be obtained by contacting an OCC Counseling Office or by visiting
