Patent ID: 8322151

Claim:
A method for diagnosing a condition of an air conditioning system using a diagnostic system, the air conditioning system including refrigerant, a condensing unit, an evaporator, a return, a return vent, a supply, and a first supply vent, the condensing unit including a condensing coil, and a compressor, the compressor including a suction port and a discharge port, the evaporator being nearer to the first supply vent than to any other supply vent, the method comprising: positioning a first transmitter adjacent to the condensing unit and connected to the condensing unit by at least one port; sensing at least one parameter of the condensing unit using the first transmitter, the first transmitter wirelessly transmitting data representative of the at least one parameter of the condensing unit directly to a receiver; positioning a second transmitter adjacent to the return vent; sensing at least one parameter of the return using the second transmitter, the second transmitter wirelessly transmitting data representative of the at least one parameter of the return directly to the receiver; positioning a third transmitter adjacent to the first supply vent with a sensing portion of a sensor inserted through the supply vent into the supply so as to accurately sense parameters of the air in the supply; sensing at least one parameter of the supply using the third transmitter, the third transmitter wirelessly transmitting data representative of the at least one parameter of the supply directly to the receiver; sending the data received at the receiver to a computing device; and analyzing the data with the computing device in order to determine a status of the air conditioning system, wherein the at least one parameter of the return comprises a return air temperature, and the at least one parameter of the supply comprises a supply air temperature.
