Arrived on site to perform cooling maintenance on Goodman split system. I checked the filter and set the thermostat into cooling. Noted to customer filter was out in the wrong way. Explained the airflow and pointed out which direction the arrow on the filter should point to. Customer did not have replacement filter at this time. I then checked temperature split, blower amps, blower assembly, blower capacitor, electrical connections, and indoor coil. I went outside and checked refrigerant levels, amp draws, connections, and capacitor readings. No issues found during this maintenance. All work is complete
