Electricians install, maintain, and repair electrical power, communications, lighting, and control systems in homes, businesses, factories, and other structures. The work encompasses reading technical diagrams and blueprints, installing wiring and electrical components, using testing devices like ohmmeters and voltmeters to check connections, inspecting electrical systems for compliance with codes, and diagnosing malfunctions. Electricians must stay current with evolving electrical codes, which vary by jurisdiction and are updated regularly for safety. The role spans diverse specializations—residential wirers focus on homes, commercial electricians handle office buildings and retail spaces, industrial electricians work with heavy machinery, and lineworkers maintain the power grid. The explosion of smart home technology, EV charging infrastructure, and solar integration has created new specialties requiring electricians to continually update their skills. Work conditions vary from new construction to renovating systems in buildings that may be decades old.

HVAC technicians install, maintain, and repair heating, ventilation, air conditioning, and refrigeration systems in residential, commercial, and industrial buildings. The work involves reading blueprints and technical specifications, installing ductwork, piping, and electrical components, charging systems with refrigerants, testing system performance, diagnosing malfunctions using specialized tools, and performing preventive maintenance. Modern HVAC work increasingly incorporates smart thermostats, zoning systems, and building automation integration. Technicians must understand electrical systems, plumbing principles, refrigeration cycles, airflow dynamics, and indoor air quality. The job varies between routine maintenance visits, new construction installations, and emergency repair calls for systems that have failed during extreme weather. Specializations include commercial refrigeration, industrial climate control, clean room environments, and energy efficiency optimization. Physical demands include working in tight spaces like attics and crawlspaces, handling heavy equipment, and exposure to temperature extremes.

Pipefitters install and maintain piping systems that carry chemicals, acids, gases, and other materials in industrial and manufacturing settings, often involving high-pressure and high-temperature systems. The work requires reading blueprints, cutting and threading pipe, fitting and welding components, testing systems for leaks, and ensuring compliance with safety codes. Pipefitters work in power plants, refineries, chemical facilities, pharmaceutical manufacturing, shipyards, and commercial buildings. Systems include steam, compressed air, hydraulics, process piping, and fire suppression. The work demands precision—systems carry hazardous materials or operate under extreme conditions where failures have serious consequences. Specialized knowledge includes different pipe materials, fitting methods, and code requirements for various applications. Physical demands include working in industrial environments, confined spaces, and elevated positions.
