## Refrigerant Charge Adjustment
**Additional Charge = (Line Length - Factory Length) x oz/ft**
AC condensing units ship with a factory refrigerant charge that covers a standard line set (typically 25 ft). For every additional foot of liquid line, extra refrigerant must be added per the manufacturer specifications (often 0.6 oz/ft for R-410A).

Exemple Résolu
50 ft line set, factory covers 25 ft, R-410A at 0.6 oz/ft, 96 oz factory charge.
- Extra length = 50 - 25 = 25 ft
- Additional = 25 x 0.6 = 15.0 oz
- Total = 96 + 15 = 111 oz = 6.94 lbs
