Mijia Air Conditioner Eco 5.2 kW

The Mijia Air Conditioner Eco 5.2 kW is a wall-mounted split air conditioner from Xiaomi’s Mijia smart-home brand, positioned between entry-level and mid-range. It has one indoor unit, one outdoor unit and an inverter compressor, and Xiaomi recommends it for rooms of 40–55 m². It is the third of four capacities in the Eco series (2.6, 3.5, 5.2 and 7.0 kW). The series came after the Mijia Air Conditioner Pro models that reached Europe in 2025.

There is no battery. The unit runs on 220–240 V / 50 Hz mains power. Rated cooling capacity is 5,400 W and heating capacity is 5,300 W, and it draws 1,928 W when cooling and 1,428 W when heating. The EU label shows A++ for cooling and A+ for heating, with a SEER of 6.9. Airflow is 1,050 m³/h. Noise is 45 / 41 / 26 dB(A) indoors at super high, medium and super low, and 55 dB(A) outdoors. Xiaomi claims up to 20.6% lower energy use with its cloud-based AI mode and 30-second cooling and 60-second heating. A STABILIZER function keeps it running through voltage fluctuations. You can use the remote, the Xiaomi Home app or a smart speaker. Wi-Fi works on 2.4 GHz only, not 5 GHz. The app shows power consumption and filter cleaning reminders, and delivers OTA updates.

In Spain the Eco 5.2 kW launched at €859, with deliveries expected from April 30 2026. I found no confirmed price for other regions. It fits a living room, open-plan space or small shop of 40–55 m² where the owner wants an inverter unit with app control and doesn’t need the GentleAir’s softer airflow. Within Mijia, the Eco 3.5 kW costs €519 and the Eco 7.0 kW €1,099, so the 5.2 kW sits between them. The Mijia GentleAir 5.2 kW overlaps with it: it has the same 5,400 W / 5,300 W capacity and the same 1,928 W / 1,428 W power draw, but uses micro-hole air flaps for a gentler airflow. Other brands offer 5.2 kW units too, such as the Midea Xtreme Save and the Haier Flexis Plus. The Midea Xtreme Save 5.2 kW is the closest direct comparison.
