Abstract
A method of adding refrigerant to an air conditioning system. The method includes measuring a first pressure inside of the air conditioning system and a second pressure inside of a container that holds refrigerant being added to the air conditioning system. The method also includes comparing the difference between the two measured pressures to empirical data in order to determine how long to pulse additional refrigerant into the air conditioning system. In addition, an apparatus configured to add refrigerant to an air conditioning system.
