Upon arrival found system not cooling. Turned system on and only outdoor unit came on. Checked inside air handler and found some wires not connected so that when the thermostat calls for cooling it didn’t send 24v to turn on blower motor. Made wire repair and motor came on. Checked outdoor unit and found the system slightly low on charge added 1lb of 410-a. System is now cooling properly at this time. Supply air temp 52 return 76
