Claim Text:
1. A method of adding refrigerant to an air conditioning system connected to a refrigerant charging system, the method comprising: obtaining a recommended amount of refrigerant for the air conditioning system; measuring a first refrigerant temperature with a first temperature sensor, wherein the first temperature sensor is located on or near a refrigerant container of a refrigerant charging system; measuring a second temperature with a second temperature sensor, wherein the second temperature sensor is located on or near the air conditioning system to be charged; determining a compensated amount of refrigerant to be added to the air conditioning system via a set of hose connectors based upon a second temperature differential between the first refrigerant temperature and the second temperature, wherein the compensated amount of refrigerant allows for compensation of refrigerant remaining in the set of hose connectors; and charging the air conditioning system with the compensated amount of refrigerant and the recommended amount of refrigerant.
