PURPOSE: An air-conditioning servicing system and method is provided to improve efficiency and reduce costs in examining and repairing an air-conditioning system. CONSTITUTION: An apparatus for servicing a malfunctioning air-conditioning system including an electric motor comprises a first sensor for sensing a first operating parameter of the malfunctioning air-conditioning system; a second sensor for sensing a second operating parameter of the malfunctioning air-conditioning system; a third sensor for sensing a motor operating parameter of the malfunctioning air-conditioning system; a micro-controller(42) in communication with the sensors for receiving a signal from each of the sensors; a hand computer(34) in communication with the micro-controller. The computer has a memory containing normal operating parameters for a plurality of air-conditioning systems. The computer is operable to compare the first, second and motor-operating parameters with the normal parameters of one of the plurality of air-conditioning systems to diagnose the malfunctioning air-conditioning system.
