Responded to a no cool issue with an air conditioning system. Diagnosed the problem and found that the capacitor had failed, preventing the compressor and fan from starting. Replaced the faulty capacitor with a new OEM part, checked the refrigerant levels, and inspected the condenser coils for any blockages. After completing the repairs, tested the system to ensure it was cooling effectively. The AC unit is now functioning properly and delivering consistent cooling to the home.
