Refrigeration and Air Conditioning Mechanics

Refrigeration and air conditioning mechanics install, maintain, repair and overhaul residential central air conditioning systems, commercial and industrial refrigeration and air conditioning systems and combined heating, ventilation and cooling systems. They are responsible for following blueprints and connecting systems to fuel and water supply lines, air ducts, and other components.

This non-vocational course introduces the student to the theory, installation, and design, operation, troubleshooting, and repair of closed/sealed refrigeration and air conditioning systems. Students will learn to test and repair various components; such as hermetic compressors, condensers, capillary tubes, expansion valves, driers, receivers/accumulators, evaporators, thermostats, defrost timers, etc. Students will also learn the safe handling of refrigerants; as well as proper soldering/brasing techniques. Students will also learn the proper use of leak testers, manifold gauges, vacuum pumps, etc. Students will also learns proper methods of changing and evacuating systems; as well as other specialized testing/ safety equipment.
