Air Conditioning Repair Service: Upon responding to a service call regarding an air conditioner's insufficient cooling performance, I conducted a thorough inspection. It became apparent during the investigation that the refrigerant levels were significantly depleted, severely impacting the unit's cooling efficiency. To address this issue, I meticulously replenished the refrigerant, ensuring it reached the optimal level necessary for effective cooling. Subsequently, I conducted rigorous testing to confirm the system's capability to deliver the desired cooling capacity and comfort. Once optimal functionality was confirmed, I shared information about our maintenance plans with the homeowner to ensure the sustained excellent performance of their system.
