Windmill features: Power: 8,000 BTU | Space size: Medium | Price: $369
The Windmill Air Conditioner may not be the cheapest on our list, but it is our top pick for the best cheap air conditioner, given the fully loaded benefits this model provides. It is a smart air conditioner that goes right into your window, its sleek design requiring a very small footprint. It comes ready to go right out of the box, so you can save the time and heartache of set-up. A convenient guide is included to steer installation in the right direction.
The unit comes with 8,000 BTU power, giving a bit more than the average air conditioner, so it is enough to cool down a medium-sized space. That in itself offers far greater flexibility in where you can use it and still feel the cooling effects. It is also the quietest machine on our list, as soft as the evaCHILL that is a fraction of its size. However, it still comes packed with features.
It is also Wi-FI-enabled and connects to a convenient app that easily works with your Android or iPhone device, allowing you the option to control the unit remotely. With an auto-dimming LED display, you can use Google Assistant or Amazon’s Alexa to control the unit by voice. In case you’re not completely satisfied with your purchase, the air conditioner comes with a 30-day, no-questions asked return policy.
