Upon inspection, the system's mechanical components were found to be functioning properly. However, significant dust and debris accumulation, along with a noticeable split in the ductwork, were identified as the root causes of strain on the system and poor air quality. Our team meticulously cleaned the affected areas, removing all accumulated dust and debris. Additionally, we repaired the split in the ductwork, ensuring a seamless and airtight connection. These corrective actions have significantly improved the system's efficiency and air quality.
