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.
