Key figures
How this selection was made
BGR built this list from buyer ratings and reviews, not from laboratory measurements. It is a useful starting point, but noise levels and savings quoted here are manufacturers' figures. Cooling power is given in BTU per hour: the larger the room, the higher the figure you need.
The five models at a glance
| Model | Capacity | Smart features | Strength | Common complaint |
|---|---|---|---|---|
| Midea U-shaped | 6,000–12,000 BTU | Matter, Alexa, Google, Apple Home | Window stays openable, 32 dB, up to 37 % savings (Midea) | Some units buzz |
| GE (SmartHQ) | 8,000–14,000 BTU | SmartHQ app, voice assistants | Wide choice of capacities | Wi-Fi pairing and connection issues |
| Windmill 6,000 | 6,000 BTU | Google, Alexa | Simple, attractive design | Thermostat can be inaccurate |
| LG Dual Inverter | 6,000 BTU and up | LG ThinQ | Energy Star, 44 dB sleep mode | Higher price |
| Della | 5,000–12,000 BTU | App with geolocation | Low price | Noise and durability concerns |
What to check before buying
- Room size: match the BTU figure to the area to be cooled; too small runs non-stop, too large cycles on and off.
- Window type: U-shaped units suit sash windows; check the measurements and the mounting kit.
- Power supply: larger units may need a dedicated circuit.
- Smart platform: choose a model that works with the assistant you already use; Matter support makes this easier.
- Energy use: an inverter and an Energy Star label reduce running costs.
Verdict
For most people, the Midea U-shaped range offers the best mix of quiet operation, smart-home compatibility and efficiency. The LG Dual Inverter is a good choice if energy use and quiet nights matter more than price. Whatever you choose, check local rules on refrigerants and installation, and have a qualified installer help if the unit is heavy or the window high up.
