I have over five years of hands-on experience working with HVAC control systems, including installing, troubleshooting, and maintaining programmable logic controllers (PLCs) and direct digital control (DDC) systems. I stay current with industry advancements by attending training sessions, reading trade publications, and participating in online forums. Additionally, I hold certifications in HVAC controls from recognized organizations, which helps me stay abreast of emerging technologies like IoT integration and energy-efficient solutions.

Once, I encountered a malfunctioning DDC system causing erratic temperature fluctuations in a commercial building. After diagnosing the issue, I discovered faulty wiring and a misconfigured PID loop. I rewired the connections, recalibrated the loop, and tested the system under various load conditions to ensure stability. The resolution required collaboration with the building automation team and thorough documentation for future reference. This experience reinforced the importance of systematic troubleshooting and teamwork in resolving complex HVAC control problems.

Safety is my top priority, so I always adhere to OSHA guidelines and manufacturer specifications. Before starting any work, I conduct a risk assessment, wear appropriate PPE, and ensure the system is properly locked out/tagged out. I also verify that electrical and pneumatic components are de-energized. Regular safety training and staying informed about code updates help me maintain compliance. Additionally, I document all safety procedures and communicate hazards to team members to foster a culture of safety on every job.

I am skilled in using multimeters, manometers, and clamp meters for electrical and pressure diagnostics. For software, I’m proficient with building automation systems like Siemens Desigo, Honeywell EBI, and Tridium Niagara. I also use Schneider Electric’s EcoStruxure and Johnson Controls Metasys for programming and troubleshooting. These tools enable me to efficiently identify issues, adjust setpoints, and optimize system performance. My familiarity with these platforms allows me to quickly adapt to new systems and provide effective solutions.

When commissioning a new system, I start by reviewing design specifications and sequence of operations to ensure alignment. I then verify sensor accuracy, calibrate actuators, and test control loops under varying conditions. Communication with stakeholders is key, so I document all adjustments and provide training for end-users. Finally, I perform a thorough system validation to confirm optimal performance and energy efficiency. This methodical approach ensures the system operates reliably and meets the client’s expectations from day one.
