What Does a Maintenance Technician Do?
Maintenance technicians install, repair, and maintain industrial equipment and facility systems in manufacturing plants and other commercial buildings. They perform preventive maintenance, diagnose mechanical and electrical problems, and restore equipment to working condition. This versatile role requires a broad range of technical skills and the ability to work under pressure when equipment breaks down.
Maintenance Technician Duties and Responsibilities
The primary responsibilities of a maintenance technician include:
- Perform preventive maintenance on production equipment according to established schedules.
- Diagnose and repair mechanical, electrical, pneumatic, and hydraulic equipment failures.
- Respond to emergency breakdown calls to restore production as quickly as possible.
- Install new equipment and make modifications to existing systems.
- Read and interpret electrical schematics, mechanical drawings, and equipment manuals.
- Maintain spare parts inventory and order replacement components as needed.
- Document all maintenance activities, repairs, and parts usage in the CMMS system.
- Perform facility maintenance including HVAC, plumbing, and building systems.
- Follow lockout/tagout, confined space, and other safety procedures during maintenance work.
- Assist with equipment upgrades, capital projects, and continuous improvement initiatives.
Required Skills and Qualifications
To succeed as a maintenance technician, you will need the following skills and qualifications:
- Mechanical repair and troubleshooting
- Electrical systems and controls
- Welding and fabrication
- PLC and motor control basics
- Preventive maintenance planning
- Blueprint and schematic reading
- CMMS software proficiency
- Safety protocols (LOTO, confined space)
Education and Training
A high school diploma plus completion of a maintenance training program, technical school certificate, or apprenticeship is typically required. Associate degrees in industrial maintenance technology, mechatronics, or a related technical field are increasingly preferred. Key certifications include industrial electrical, PLC programming, welding, and HVAC. Many employers also expect OSHA 10-Hour or 30-Hour General Industry certification. On-the-job training is extensive, as technicians must learn the specific equipment and systems at their facility. Multi-skilled technicians who combine mechanical, electrical, and controls knowledge are most valuable.
Salary and Job Outlook
Average Salary: $42,000 - $65,000 per year
Maintenance technicians are in extremely high demand across manufacturing, food processing, utilities, and commercial facilities. An aging workforce and the increasing complexity of modern production equipment are driving a significant skills shortage. Technicians who develop expertise in automation, robotics, PLCs, and predictive maintenance technologies are particularly sought after. Career advancement paths include maintenance supervisor, maintenance planner, reliability engineer, or facilities manager. The profession offers strong job security as equipment maintenance is essential to every manufacturing and facility operation.
