Facility Maintenance Mechanical Trades
Facility Maintenance Mechanical Trades technicians install, maintain, and repair heating, ventilation, air conditioning, and refrigeration systems; maintain and repair plumbing systems, and troubleshoot and repair electrical controls. Their knowledge and skills are in demand throughout Alaska in homes, office buildings, restaurants, public buildings, seafood processing and manufacturing plants and shipping industries.
The blend of classroom instruction, lab, and live work practice helps students to learn the necessary skills to become a Facility Maintenance/Mechanical Trades technician. The course is fast-paced and challenging. Students should have some mechanical aptitude, strong mathematics and reading skills, and the ability to their time productively. Students train on common domestic and commercial refrigeration systems and a variety of plumbing and heating systems. Heat pumps, air conditioning and distribution systems, compressors, evaporators, condensers, control devices, control valves, electrical controls and motors, and electrical trainers are also used in training.
Approximately 50% of the training is hands-on and 50% is classroom instruction. Training includes outdoor activities, so students need appropriate clothing for cold and wet working conditions.
To provide training through classroom instruction, demonstration, and practical application, methods for installation, maintenance, service, repair and diagnostics to maintain installations and repair various facility equipment.
