During the inspection, I discovered significant restrictions in the coil due to accumulated debris, which was impeding proper airflow. Additionally, the blower wheel was covered in dirt, further compromising the system's efficiency. To address these issues, I replaced the old filter grills with new ones to ensure better filtration. Furthermore, I thoroughly cleaned the ductwork to remove any accumulated dust and debris, enhancing overall air quality and system performance. These actions were taken to restore optimal functionality and efficiency to the system.
