Thank you for reaching out. To accurately check the refrigerant charge on your air conditioner, please follow these steps:


  1. Recover and Weigh the Refrigerant – Reclaim all refrigerant from the system and weigh the recovered amount. Compare this to the specified charge listed on the unit's nameplate.
  2. Check for Leaks– If the recovered amount is less than specified:
    • Inspect both the indoor and outdoor units for leaks.
    • If no obvious leaks are found, check the pipework for any issues.
  3. Warranty Service Note – If this is a warranty service call, please note that checking the installation is not covered under warranty. Any issues related to installation would not be eligible for warranty repair.
  4. System Evacuation – Once any leaks are identified and repaired, evacuate the system to 500 microns or lower to ensure no moisture or air remains in the system.
  5. Recharge the System – Weigh in a new refrigerant charge based on the exact amount specified on the unit's nameplate to ensure proper operation.
