Commercial HVACR Field Service Technician

A Day in the Field Picture this: you start your morning reviewing the dispatch on your tablet, load up your company vehicle, and head to a client site. Your first stop is a rooftop where you diagnose an RTU that is short cycling. You reference wiring diagrams, verify airflow, test the refrigerant circuit, and bring the unit back to peak performance.

Next, you complete a preventive maintenance visit on a bank of split systems and package units, tuning equipment and documenting findings. Throughout the day you communicate clearly with customers, recommend proactive repairs, and close each call with accurate reports — all while following safety policies and industry regulations. When needed, you rotate through on-call to keep critical facilities running.
