The Heating, Ventilation & Air Conditioning Technology program prepares students to install, service and repair refrigeration and air conditioning systems. including geothermal ground source heat pumps.  Graduates may be employed with small businesses in the selling and maintenance of residential systems.

Many job opportunities exist to install and maintain the refrigeration systems of modern supermarkets.  Still other graduates may be employed in the maintenance of HVAC systems in buildings and factories.  Small classes in basic refrigeration and air conditioning theory are enhanced with extensive hands-on training in laboratories and on in-service equipment.

Comprehensive coverage is given to electrical motors, controls and wiring and systems diagnosis and repairs.  Students are required to join the Refrigeration Service Engineers Society (RSES), a nationally recognized educational certification agency.  RSES training materials are used in the classroom, and students can become certified in four RSES areas if they pass the required examinations.  Many contractors are RSES members and seek employees with certification.

The Heating, Ventilation & Air Conditioning Technology program has three national accreditations:  HVAC Excellence, the Partnership for Air Conditioning, Heating, Refrigeration Accreditation (PAHRA), and the National Association of Industrial Technology (NAIT).

Enrollment in the Heating, Ventilation, & Air Conditioning Technology program is limited and students are selected for this program on a competitive basis.  Contact the Office of Admissions for the specific application requirements and deadline.
