Upon inspection of the outside unit found the inverter board displaying a fault code for low refrigerant. Cycled power and the system started up as designed. Checked evaporator coil for leaks. Electronic leak detector signaled at multiple locations. Coordinated with the office to get a coil ordered. Once part arrives will reach out and schedule installation.
