Responded to a no AC call and discovered the system was not functioning. Upon inspection, I identified a failed capacitor and low refrigerant levels as the primary issues. I replaced the faulty capacitor and recharged the refrigerant to the required levels. After completing the repairs, I performed a comprehensive test to ensure the system was cooling efficiently and operating correctly. The AC unit is now fully operational, providing consistent and effective cooling throughout the home, ensuring the homeowner's comfort.
