Additional Charge vs Total Line Set Length
Formule
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.
- 01Extra length = 50 - 25 = 25 ft
- 02Additional = 25 x 0.6 = 15.0 oz
- 03Total = 96 + 15 = 111 oz = 6.94 lbs
Questions Fréquentes
How do I know the oz per foot for my unit?
Check the manufacturer installation manual. Common values for R-410A are 0.5-0.8 oz/ft depending on the liquid line diameter and system capacity.
Can I have too much refrigerant?
Yes, overcharging causes high head pressure, reduced efficiency, possible compressor damage, and liquid slugging. Always verify charge with superheat or subcooling readings.
