Job description

EOA Technologies is seeking a Commercial HVAC/R Technician to support Data Center & Mission-Critical Systems. You will be responsible for:

• Performing installation, maintenance, troubleshooting, repair, startup support, and operational verification of commercial HVAC/R systems supporting data centers, critical facilities, and large commercial buildings.
• Works with chillers, air-handling systems, pumps, cooling towers, CRAC/CRAH units, controls, and associated electrical and mechanical equipment to ensure reliable, efficient, and continuous cooling operations.
• Conducts chiller pre-start inspections and startup readiness checks for mission-critical data center cooling systems.
• Verifies mechanical completion, electrical power, control wiring, refrigerant and oil conditions, chilled-water and condenser-water flow, valve positions, pump operation, strainers, sensors, safeties, interlocks, and BAS/BMS communication before equipment startup.
• Perform pre-start inspections on air-cooled and water-cooled chillers prior to manufacturer or commissioning-agent startup.
• Verify chilled-water and condenser-water system readiness, including pumps, valves, strainers, expansion tanks, flow switches, pressure readings, and proper system circulation.
• Inspect compressor, evaporator, condenser, refrigerant, oil, electrical, and control components for proper installation and operating readiness.
• Confirm correct electrical service, phase rotation, voltage, amperage, grounding, disconnects, breakers, control power, and equipment connections.
• Validate safety circuits, alarms, sensors, interlocks, emergency shutdowns, freeze protection, flow proving, and equipment sequencing.
• Assist OEM technicians and commissioning teams during chiller startup, functional performance testing, and system commissioning.
• Record startup conditions, operating pressures, temperatures, superheat/subcooling where applicable, amperage, water temperatures, flow conditions, and other performance data.
• Troubleshoot commercial HVAC/R systems using electrical schematics, mechanical drawings, control diagrams, diagnostic tools, and BAS/BMS data.
• Maintain and repair centrifugal, screw, scroll, and reciprocating refrigeration systems, as applicable.
• Service AHUs, RTUs, VAV systems, fan-coil units, pumps, cooling towers, heat exchangers, exhaust systems, and hydronic equipment.
• Support CRAC and CRAH systems used for precision environmental control within data halls and other critical spaces.
• Diagnose mechanical, refrigeration, electrical, airflow, hydronic, sensor, actuator, and control-system faults.
• Perform preventive and predictive maintenance on HVAC equipment to maximize reliability and minimize unplanned downtime.
• Inspect belts, bearings, motors, contactors, relays, capacitors, VFDs, actuators, dampers, valves, filters, coils, and electrical connections.
• Support BAS/BMS point-to-point verification, alarm testing, equipment sequencing, lead/lag rotation, and control-system troubleshooting.
• Coordinate with electricians, controls technicians, commissioning agents, OEM representatives, facility engineers, and construction teams during equipment installation and startup.
• Follow lockout/tagout (LOTO), electrical safety, refrigerant-handling, confined-space, PPE, and site‑specific data‑center safety procedures.
• Maintain accurate maintenance records, startup documentation, equipment logs, deficiency lists, and commissioning reports.
• Respond to cooling‑system alarms and equipment failures in mission‑critical environments where HVAC reliability directly affects IT operations and facility uptime.
• Identify equipment deficiencies before startup and coordinate corrective actions to prevent equipment damage, nuisance trips, or commissioning delays.
• Maintain compliance with EPA refrigerant regulations, manufacturer specifications, mechanical codes, and company safety standards.
