Program Objective

Our collective concerns about the future health of the environment are at the heart of today’s dynamic Heating, Ventilation, and Air Conditioning Technology industry, driving progressive changes through planning and implementation. The shift away from some of the more conventional HVAC systems still used in older residences and commercial buildings has been dramatic and continues to evolve. Newer systems focus on renewable energy sources, energy efficiency, and creating comfortable indoor environments. One of the primary objectives of the HVAC curriculum is to introduce students to Green Technology concepts as they apply to HVAC systems. Students are prepared to confidently enter this vibrant field possessing fundamental skills required to service, troubleshoot, and repair commercial and residential indoor HVAC air management systems. Students also learn proper refrigerant recovery and recycling techniques, and are encouraged to complete Environmental Protection Agency (EPA) certification testing. Upon successful completion of this program, graduates will meet the essential skills and knowledge required for employment as an entry-level HVAC technician. With additional experience graduates may pursue opportunities allowing them to work independently, without direct supervision, supervise crews or teams of other technicians, or start their own business. Graduates may also choose to specialize in one or more specific areas of the HVAC market including refrigeration, air conditioning, and heating. Students will also be trained on OSHA 30 standards and given the opportunity to take and pass the exam. OSHA 30 is mandated by the State licensing board for all apprentices. An apprentice needs to have his or her OSHA 30 in order to seek qualification for future licensure. In addition, students are also prepared to take the following exam EPA 608 exam, 410a universal, heat load analyst, certified energy auditor, and green awareness exams. Students will be required to complete out-of-class assignments in each course in this program.
