Mr Hanna greeted us at door and showed us the alerts being displayed on his thermostat causing system not to function. Performed AC diagnostics: thermostat and outdoor equipment CDA board displaying high pressure lockout faults. Further inspection located a break in high pressure switch causing intermittent system lockout/faults. Performed courtesy repair: spliced the severed high-pressure switch back together and rerouted differently. After repair system automatically cleared alerts/faults. Put demand call for cooling from thermostat and system began functioning properly. Refrigerant charge is at manufacturers operate specifications. System cooling, draining, and functioning properly again at this time. Technician no charged homeowner due to call back and maintenance just performed.
