<b>WHO YOU ARE</b>
This candidate is responsible for advanced HVAC and mechanical maintenance, troubleshooting, repair, and equipment operation across the Orlando campus. Acts as a senior technical resource on the HVAC/mechanical team, supporting complex troubleshooting, system optimization, preventive maintenance, planned outages, and the technical development of other HVAC personnel.
Provides advanced support for building automation system (BMS) operation and troubleshooting, using alarms, trends, points, schedules, and sequences to diagnose performance issues and failures in mechanical equipment, controls, sensors, actuators, communications, or programming. Performs field verification and repair of HVAC controls within trained capability and coordinates with controls contractors or Engineering when specialized assistance is needed.
Maintains and troubleshoots commercial and industrial HVAC equipment and associated mechanical systems, including air‑handling units, chillers, pumps, cooling towers, exhaust, hydronic loops, variable‑air‑volume systems, controls, and related infrastructure.
Works closely with the HVAC/Mechanical Maintenance Supervisor and Planner/Scheduler to execute planned and emergent tasks. Provides field technical leadership on complex work, assists with recurring‑failure troubleshooting, supports root‑cause analysis, mentors less‑experienced technicians, and coordinates with Engineering and specialized contractors as required. Ensures all preventive and corrective maintenance complies with safety, environmental, quality, technical, and documentation standards. Accurately records work and equipment conditions in LMBuildings and identifies opportunities to improve equipment reliability, BMS performance, sequences of operation, and preventive‑maintenance requirements.
Primary responsibilities include advanced HVAC/mechanical troubleshooting and repair, BMS operation and troubleshooting, controls diagnostics and repair, preventive and corrective maintenance, system performance analysis, planned‑outage support, technical field leadership, technician mentoring, root‑cause troubleshooting, contractor coordination, Quick Path project support, and work‑order documentation. Installs, services, modifies, rebuilds, and repairs air‑conditioning and refrigeration systems and equipment in an industrial or commercial establishment in accordance with applicable building codes and safety regulations. Tasks range from periodic inspection to locate and determine cause of equipment malfunctions to conducting maintenance programs to prevent failure of such equipment as centrifugal compressors, electrical controls, evaporative condensers, pumps, fans, and heating equipment. Charges air‑conditioning systems with refrigerant; checks and tests for leaks; sets and adjusts controls and regulators; fabricates, assembles, and installs ductwork; overhauls equipment. May service, modify, and maintain centralized HAC computer systems and make program corrections. May be required to install and maintain high‑technology clean room environments.
