HVAC Systems & APM Operations Technician

A day in the life — Hawthorne, CA You start your shift by walking the facility, checking temperatures, airflow, and system status. A vibration alert on a rooftop unit prompts a quick inspection; you isolate the issue, swap a worn component, and document the repair. Next, you pivot to the O&M site to review APM Central Control consoles, run a diagnostic on a wayside subsystem, and prepare for a scheduled preventive maintenance window.

Midday, a service request comes in—an office zone is running warm—followed by a training block to maintain your certifications. By the end of the day, your logs are complete, the environment is comfortable, and the system is ready for tomorrow.
