Upon arrival, I inspected the furnace and identified that the fire eye was obstructed, preventing proper ignition. I carefully cleaned the fire eye, ensuring all debris and buildup were removed. Following the cleaning, I conducted a series of tests to confirm the furnace was functioning correctly. The furnace was then restarted, and it ignited smoothly, indicating the cleaning was successful. I verified the system's performance and ensured everything was operating efficiently. The job was completed to the client's satisfaction.
