How to Calculate Refrigerant Line Charge

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

  1. Gather system information, including manufacturer, model, capacity, line set length, and diameter.
  2. Consult the manufacturer’s documentation for specific guidelines.
  3. Determine the target superheat and subcooling values.
  4. Measure ambient conditions (temperature and humidity) around the outdoor unit.
  5. Use the manufacturer’s guidelines to calculate the required refrigerant charge based on the gathered information.
  6. 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.
