HVACR Field Service Specialist — Chillers & Boilers

A day in the life

You start your morning with a service dispatch, tools ready—ohmmeter in hand, gauges calibrated. By mid-morning, you’ve diagnosed a stubborn chiller issue, welded a small bracket to secure a vibrating line, and replaced a failing pump motor. The afternoon takes you to a property where you complete routine maintenance to keep systems efficient and compliant with safety standards. Along the way, you explain findings to clients in plain language, document your work, and drive a company vehicle between sites with a clean, professional presence.
