Mijia Air Conditioner Eco 3.5 kW

The Mijia Air Conditioner Eco 3.5 kW is a wall-mounted split air conditioner from Xiaomi’s Mijia line. It is an inverter heat pump, so it cools and heats, and it is priced for the entry-to-mid range. Xiaomi recommends it for rooms of 15 to 25 m². The Eco series launched in Spain in April 2026, next to the older Pro Eco models, in 2.6, 3.5, 5.2 and 7.0 kW versions.

Cooling and heating capacity are both 3,700 W. The unit draws 1,423 W when cooling and 916 W when heating. It is rated A++ for cooling and A+ for heating, with a SEER of 6.3. The system is a full DC inverter, and Xiaomi claims up to 24.5% lower energy use in AI mode. It also quotes 30 seconds to cool and 60 to heat. A STABILIZER function is meant to protect the unit from unstable voltage. Control is through the Xiaomi Home app or Google Assistant. Other features include self-cleaning, a timer, sleep curves, a dry mode and automatic restart after a power cut.

It launched in Spain at €519. It suits a bedroom or small living room where the buyer wants app control and a heat pump but doesn’t need the Pro Eco’s A+++ rating. Xiaomi sells two close neighbours: the Mijia Air Conditioner Eco 2.6 kW at €469 in Spain, and the Mijia Air Conditioner Pro Eco 3.5 kW, which launched at €699 with 3.6 kW of heating capacity and an A+++ rating. From other brands, the Haier Flexis Plus 3.5 kW has an app, voice control and a 3.5 kW design cooling load. The Midea Xtreme Save Lite 12 is a 3.6 kW unit where Wi-Fi costs extra. The closest match is the Midea Xtreme Save Pro 12 (3.5 kW), which includes Wi-Fi.
