Abstract: An HVAC line set analyzer system is provided. The system includes a base unit and a remote unit, wherein the base unit is in communication with the remote unit. The base unit is configured to couple to an end of tubing of an HVAC line set and the remote unit is configured to couple to an opposing end of the tubing the HVAC line set. The base unit and the remote unit operate together in order to purge the tubing of all contaminates, remaining gases and so forth, equalize the temperature and then measure the length of the tubing of the HVAC line set, which length is an unknown length. This is done with two measurements. The first is the length of the tubing, and the second determines a number of sharp bends in that tubing and calculates an equivalent tubing length associated with the number of sharp bends.
