Heating, Ventilation & Air Conditioning Technology (A.A.S.)

One of the fastest-growing service occupations, Heating, Ventilation and Air Conditioning has seen major changes over the past years as a result of the national emphasis on fuel conservation and environmental concerns.

Every private residence, business, industry and agency needs the skill of technicians trained in the installation, maintenance and repair of air conditioning, refrigeration and heating systems.

Students are trained to diagnose and repair malfunctions; size, fabricate and install air duct systems; and estimate cooling and heating loads for selection of the most efficient systems for a given building. Practical training in a well-equipped shop and outside installation of service projects gives students on-the-job experience before they graduate. EPA technician certification is taught and the test is offered to all curriculum students.

Advisement Information

Program notes

It is best to start in the fall semester.  Place students in ACR classes even if they need developmental coursework. If a student wishes to enroll during spring or summer term, advise for general education courses. A student may also enroll in ACR 109 in the spring. In the summer a new student may enroll in ACR 150 and ACR 160, but check with department head first.

Students will earn an A.A.S., Major in HVAC Technology (HVA3) by the completion of the Refrigeration Applications Certificate, the Heating Fundamentals Certificate and completion of (18 credit hours-which includes CPT 101 or CPT 169) of general education.

Courses are offered during day and evening hours

Top-quality tools, meter and gauges, which are required for this program, will cost $500 - $700.  There is a list at the bookstore, or you can contact Bill Cockrell for more information.
