In my previous role, I encountered a malfunctioning chiller that was causing inconsistent cooling in a large office building. After diagnosing the issue, I discovered a refrigerant leak and a faulty compressor. I repaired the leak, replaced the compressor, and recalibrated the system to ensure optimal performance. This experience taught me the importance of thorough diagnostics and precision in HVAC maintenance.

I prioritize tasks based on urgency and impact. For instance, if a system failure affects critical operations, I address it immediately. Routine maintenance, such as filter replacements and inspections, is scheduled around urgent tasks to ensure efficiency. I also communicate with supervisors to adjust priorities as needed.

I strictly adhere to OSHA guidelines, including wearing personal protective equipment (PPE), ensuring proper ventilation, and following lockout/tagout procedures to prevent electrical hazards. I also conduct regular safety checks on tools and equipment to minimize risks.

I regularly attend industry workshops, read technical journals, and participate in online courses to stay informed about new technologies and best practices. For example, I recently completed a course on energy-efficient HVAC systems, which has helped me implement cost-saving measures for clients.

I use a systematic approach to troubleshooting, starting with identifying symptoms, checking system logs, and testing components. For example, if a system is overheating, I inspect the condenser, check refrigerant levels, and test the thermostat. This method ensures accurate diagnosis and efficient repairs.
