Midea 12,000 BTU Smart Inverter Window Unit with Heat
The Midea 12,000 BTU window unit provides substantial cooling for larger living spaces while adding built‑in heating for shoulder seasons. It is designed for rooms up to 550 square feet and features an energy‑saving inverter compressor for improved efficiency. The unit offers five operation modes—Heat, Auto, Cool, Dry, and Fan—with three fan speeds and a 24‑hour timer. A remote control and a SmartHome/App integration enable convenient control from anywhere, and voice compatibility with Alexa and Google Assistant adds hands‑free operation.
