Air Conditioning System Repairs: While conducting a thorough diagnostic assessment, I identified a refrigerant leak as the root cause of insufficient cooling in the AC unit. To address this issue, I meticulously located and sealed the leak, preventing further refrigerant loss. Following the repair, I proceeded to recharge the refrigerant to its optimal level, ensuring the AC unit regained its full cooling capacity. This comprehensive intervention aimed not only to fix the immediate problem but also to promote long-term efficiency and performance.
