One challenging repair I completed involved a large commercial freezer that was not maintaining temperature. After diagnosing the issue, I discovered a faulty compressor and a refrigerant leak. I replaced the compressor, repaired the leak, and recalibrated the system, ensuring it operated efficiently and met safety standards. This experience reinforced my ability to troubleshoot complex systems and work under pressure.

I prioritize tasks based on urgency and impact. For example, I address equipment failures that affect operations immediately, followed by preventive maintenance to avoid future issues. I also consider the severity of the problem, such as food spoilage risks, and coordinate with supervisors to ensure efficient scheduling.

I always follow OSHA guidelines and wear appropriate personal protective equipment, such as gloves and safety goggles, when handling refrigerants. I ensure proper ventilation and use leak detectors to identify hazards. Additionally, I train regularly on safe handling of chemicals and emergency procedures to minimize risks.

I regularly attend industry workshops, read technical journals, and participate in online courses to stay informed about new refrigeration technologies, such as energy-efficient systems and eco-friendly refrigerants. This helps me apply the latest advancements to improve system performance and sustainability.

I have extensive experience using electronic leak detectors and soap bubble tests to locate refrigerant leaks. I also inspect system components, such as valves and connections, for wear and damage. Once identified, I repair or replace faulty parts and recharge the system to ensure proper operation.
