Trane RTU Maintenance

Near Research Blvd. Austin, Tx 78758
Trane RTU Maintenance. I cleaned the condenser coil. This coil has severe hail damage picture provided. I washed out the evaporator coil and cleaned out the drain pan, I found circuit 1 compressor low on refrigerant. Charged 4lbs of r410a, I found the main control board faulty causing the system to keep compressor stage 2 off. I had to jump out the board completely and run contactor voltage for both compressors. No further action needed today.
