To make it simple and to save you money all they need to do is the
following:
1. Have them pump down the system.
2. After the system has been pumped down they can now open and repair the
leak on the suction line.
3. After leak has been repairs and leaked checked they only have to run a
short vacuum on the line set.
4. They then open up the line set to the refrigerant they had pumped down.
5. Top off the system.
