Abstract
An air conditioning servicing system utilizes a number of sensors which monitor various operating parameters of a malfunctioning air-conditioning system. These operating parameters are provided to a hand held computer along with an identifier of the malfunctioning air-conditioning system. The hand held computer contains the normal operating parameters for a plurality of air-conditioning systems. The hand held computer compares the measured operating parameters with the normal operating parameters for the specific air-conditioning system to provide diagnostic results for the malfunctioning system and possible service procedures. If the hand held computer does not recognize the malfunctioning air-conditioning system identifier, a wireless connection is made through the Internet to a master computer which has a larger data base.
