Performed one system ac tune up and efficiency checklist. We discovered on tune up check list and evaluated that the hard start kit ruptured, there was no access door to evaporator coil, there was a burnt wire going to start capacitor and system was low on refrigerant. We let the home owner know of concerns and Mr Don approved for us to make the repairs. After repairs we flushed condenser coil and tested refrigerant operations, compressor and starting amps. The system is working to manufacture specs at this time.
