Industry Definition & Overview
Commercial and Industrial Machinery and Equipment (except Automotive and Electronic) Repair and Maintenance (NAICS 811310) encompasses establishments primarily engaged in repairing and maintaining commercial and industrial machinery and equipment per the U.S. Census Bureau[5]. Activities include heavy equipment repair for construction and mining machinery, industrial machine tool servicing, forklift and material handling equipment maintenance, armature rewinding and electric motor repair, commercial refrigeration equipment servicing, and welding repair services for industrial applications.
The industry serves manufacturing plants, food processing facilities, construction contractors, mining operations, and municipal agencies that depend on continuous equipment uptime to maintain production schedules. Service providers range from single-technician mobile repair operations to large multi-location firms with specialized capabilities in hydraulic systems, pneumatic controls, CNC machine tools, or commercial refrigeration. Caterpillar, John Deere, and Cummins dealer networks provide authorized repair services for their respective equipment lines, while independent repair shops compete on pricing, response time, and cross-brand capability. Preventive maintenance contracts provide recurring revenue streams, with many industrial customers shifting from reactive break-fix service to scheduled maintenance programs that reduce unplanned downtime. EPA Section 608 technician certification is required for technicians who service commercial refrigeration equipment containing regulated refrigerants.
Per the SBA Table of Size Standards[6], the size standard is $13 million in average annual receipts. OSHA[7] general industry standards govern workplace safety for repair technicians working with heavy machinery, electrical systems, pressurized hydraulic lines, and welding operations.
