I arrived to the property for outdoor unit not coming on or cooling. I proceeded to the outdoor unit and found it to be in a lockout. The outdoor disconnect box does not have a disconnect so the tenant Zach,shut off power at the indoor breaker panel. Once shut off I found the unit to be in a lockout and also found the entire unit to be dirty and restricting the airflow t9 the outdoor coils. I rinsed the opuntia only and turned it back on. I checked the pressures and everything tested within range. The unit is cooling on departure. I received verbal authorization to charge Shane today and also mentioned out maintenance plan to avoid future issues. He declined at this time.
