Upon inspection, it was determined that the air conditioning system's coil and blower wheel required thorough cleaning to ensure optimal performance. I began by carefully accessing the coil, which had accumulated dust and debris over time. Using specialized tools and cleaning agents, I meticulously removed the buildup, ensuring that the coil could efficiently transfer heat. Next, I turned my attention to the blower wheel, which had also gathered dirt and grime. I disassembled the necessary components to access the wheel and used a combination of brushes and cleaning solutions to eliminate the contaminants. This process restored the blower wheel's efficiency, ensuring smooth and effective air circulation. After completing the cleaning, I reassembled all components and tested the system to confirm that it was functioning correctly. The air conditioning system is now clean, efficient, and ready for optimal performance.
