BAS Technician – HVAC Monitoring and Controls

We are seeking a technically skilled and reliable Mid-Level BAS (Building Automation System) Technician to support the monitoring, maintenance, and optimization of HVAC systems via BAS platforms. The technician will play a critical role in maintaining environmental conditions across cleanrooms, labs, or process zones by ensuring precise control of temperature, humidity, and pressure. This role is ideal for professionals with hands-on experience in HVAC automation and building control systems.

Key Responsibilities:

1. BAS System Operation & Monitoring

• Monitor environmental parameters such as temperature, humidity, pressure, and airflow via BAS.

• Manage setpoints and control logic to maintain stability in regulated environments.

• Respond to and investigate system alarms or deviations.

2. Troubleshooting & Diagnostics

• Perform basic to intermediate troubleshooting on HVAC control loops and field devices.

• Resolve issues with sensors, actuators, dampers, and communication signals between BAS and HVAC equipment.

• Collaborate with maintenance and engineering teams to address persistent faults or performance degradation.

3. Preventive Maintenance & Calibration

• Execute preventive maintenance tasks for BAS equipment and control devices.

• Assist in calibration of sensors (temperature, pressure, humidity) and verify signal integrity.

• Ensure proper functioning of dampers, valves, actuators, and interface modules.

4. Environmental Control Compliance

• Support maintenance of classified zones such as cleanrooms and process areas according to GMP or ISO 14644 standards.

• Verify system performance for pressure cascades, air changes per hour (ACH), and climate conditions.

• Assist in HVAC system qualification and environmental validation activities.

5. Documentation & Reporting

• Maintain logs of alarm events, parameter changes, and maintenance activities using CMMS or BAS reporting tools.

• Document field device mappings, system drawings, and loop diagrams.

• Support compliance documentation for audits and internal reviews.

6. Collaboration & Technical Support

• Coordinate with HVAC technicians, QA, and production personnel to meet operational requirements.

• Support integration or upgrade of HVAC equipment into the BAS network.

• Provide basic training or guidance to junior team members when needed.

Key Focus Areas:

• BAS System Monitoring and Parameter Control

• HVAC Sensor and Actuator Maintenance

• Alarm Management and Fault Diagnostics

• Compliance with Cleanroom and Regulatory Standards (GMP, ISO 14644)

• Trend Analysis and CMMS Documentation

• Support for System Optimization and Upgrades

Qualifications:

• Diploma or Degree in Instrumentation, Automation, Electronics, HVAC, or Electrical Engineering.

• 3–6 years of experience working with BAS/BMS in a controlled environment (e.g., pharma, food, hospitals).

• Strong technical understanding of HVAC controls and automation fundamentals.

Preferred Skills:

• Experience with platforms such as Honeywell, Siemens, Schneider Electric, Johnson Controls.

• Knowledge of AHUs, chillers, ductwork pressure controls, and control loop configurations.

• Familiarity with GMP standards, ISO classifications, and cleanroom HVAC requirements.

• Basic knowledge of alarm trending, compliance reporting, and SOP usage.
