HVAC Repair AC Not Cooling

This air conditioner was not cooling correctly. The AC had a 10 degree split across the evaporator coil. Therefore I go outside and check pressures. I find the system charge is low. almost no subcooling. Therefore I add 410a refrigerant until I achieve the proper subcooling.
