Associate Degree
A.S. in Mechanical-Electrical Technology
MET Program Information
The Mechanical-Electrical Technology (MET) program provides instruction in design, installation, operation, repair, and maintenance of a wide range of mechanical and electrical equipment from small residential equipment to large commercial and industrial facilities. The entire spectrum of mechanical and electrical systems is covered including energy management, mechanical system commissioning, indoor air quality, building automation systems, refrigerant recovery and management, electrical controls, pneumatic controls, electronic controls, instrumentation, and heat pumps. These systems include heating, ventilating, air conditioning, and refrigerating (HVAC/R).
Students will learn the theory and fundamentals of mechanical equipment and be exposed to hands-on training in sophisticated training laboratories. Laboratory equipment that students will work with include a water cooled chiller, cooling towers, steam and hot water boilers, thermal energy storage system, heat reclaim system, power management system, packaged and split system air conditioners, furnaces, and high, medium, and low temperature refrigeration systems. Students will also configure, program, and commission several Direct Digital Control (DDC) Systems, pneumatic systems, variable frequency drive (VFD), and programmable logic controllers (PLC), and work directly on the operating systems in the laboratory facility.
The program includes both day and evening lecture and laboratory class sections. Classes are conducted as both lecture and laboratory. Effective writing, verbal communication, electronic communication, sketching, drafting, mechanical calculations, and computer skills are emphasized across the curriculum.
Recommended High School Preparation
Completion of college preparatory English and general mathematics courses is highly desirable but not required. Courses in drafting, algebra, and computer fundamentals will be beneficial.
Program Costs
In addition to normal student expenses such as tuition and textbooks, MET students must purchase safety glasses for use in laboratory and shop classes. If this fee creates a financial burden, students should consult the Financial Aid Office for possible assistance.
