The Mijia Air Conditioner Eco EGAT Label No.5 with 1 Star 18000BTU does not require regular refrigerant refilling, as the refrigerant circulates within a sealed system and does not deplete under normal conditions. This is designed to maintain stable cooling performance under normal operating conditions.
Refrigerant refilling is only necessary if a leak occurs in the system, which is uncommon during normal use. As long as the system remains sealed, the air conditioner can operate reliably without routine refrigerant maintenance.
If you suspect any refrigerant leakage, please turn off and stop using the device immediately, then contact the official after-sales service center promptly for professional inspection and support.
