Upon inspection, it was determined that the unit requires a new heat exchanger to ensure optimal performance and efficiency. After discussing the issue with the customer, they approved the replacement. I meticulously assessed the current system, ensuring all necessary components and tools were prepared for the installation. The old heat exchanger was carefully removed, and the new one was installed with precision. The unit was then tested to confirm that it operates correctly and efficiently. The customer was informed that the installation will be completed tomorrow, ensuring they have a fully functional unit soon.
