Did a maintenance on a mini split unit. During the maintenance I cleaned the filters, did a water test drain line was clear. Supply temperature was 95 degrees. Out side I put my gauges on a refrigerant levels are in range for the unit. Did a amp check on the compressor and fan motor both are in range of the system name plate. System is operating properly at this point.
