## How to Calculate Refrigerant Line Charge

To calculate the refrigerant charge for a split-system air conditioner or heat pump:

- Gather system information, including manufacturer, model, capacity, line set length, and diameter.
- Consult the manufacturer’s documentation for specific guidelines.
- Determine the target superheat and subcooling values.
- Measure ambient conditions (temperature and humidity) around the outdoor unit.
- Use the manufacturer’s guidelines to calculate the required refrigerant charge based on the gathered information.
- Fine-tune the refrigerant charge using HVAC tools, if needed.

Always refer to the manufacturer’s guidelines and consult with a qualified HVAC professional for accurate calculations specific to your system.
