The customer reached out for a comprehensive AC maintenance service to ensure optimal performance for the upcoming summer. Upon inspection, I found that the fan blades had accumulated debris, causing the unit to operate less efficiently. Additionally, the refrigerant level was slightly low, which could have affected the system’s cooling capacity. I cleaned the fan blades, topped off the refrigerant, and performed a thorough check on all system components. After running the system, it was cooling effectively again, ensuring the customer’s home stays comfortable all season long without unnecessary energy waste.
