Windmill Review 2024 → Powerful, Smart Window Air Conditioner

Let’s start with the most popular window smart air conditioner, the Small AC 6,000 BTU. With its 6,000 BTU capacity, this modern window air conditioner can properly cool your up to 250 sq ft room without breaking the bank.

Moreover, it also features a minimalist yet elegant design, making it a great add-on to enhance your living space. With its curved edges, clean lines, and auto-dimming LED display, this smart window AC is a beautiful add-on to your home.

Not only elegant, but this Windmill window air conditioner is also powerful thanks to its incredible top vent design that blows air up and out at the right angle. With this design, this window air conditioner can deliver better airflow to cool down your heated room temperature.

Another good thing about this Windmill smart window AC is, for sure, its smart features. With the smart features available, you can control this window AC via remote control, mobile app, or smart home assistant, such as Google Assistant, Siri, or Amazon Alexa.

Amazingly, the brand created this smart window air conditioner with eco-friendly refrigerant (R32) that is good for the planet.

So, do you have a small room measuring 250 sq ft and planning to find a suitable AC unit? If you do, we highly recommend choosing this Small AC 6,000 BTU. Priced at $329, this is a great bargain!

However, suppose you have a room of up to 350 sq ft. Then you can choose a larger version, namely Medium AC 8,000 BTU.

The next window Windmill smart air conditioner is the Large AC with WhisperTech 10,000 BTU. This AC unit is highly suitable for those with large rooms up to 450 sq ft and want to chill their rooms.

In addition, this Windmill large window AC is also equipped with WhisperTech technology that previous products did not have. This technology ensures that this AC unit has a noise operation at 42 dB, much quieter than the small window AC.

How about the design? Like the Windmill small AC, this large window AC with WhisperTech comes with a minimalist and elegant design. With this design, you no longer have to deal with the typical bulky yet ugly AC. Leave that behind, and move on to the minimalist one!

Not only that, but this Windmill large window AC also comes with excellent top vents design for better airflow delivery performance to all corners of the room.

Better yet, it also has smart features allowing you to control this window AC easily. You can control this smart window air conditioner using a remote control, mobile app, and even smart home voice assistants, such as Amazon Alexa, Google Assistant, and Siri.

Sustainable. That’s the point of this Windmill large window AC. It uses eco-friendly refrigerant (R32) to cool your room without harming the planet. Such a great thing, right?

• Weights: ‎‎63 Pounds

With the additional technology and the much larger dimensions, you have to pay a higher price. So, to get your hands on this window Windmill smart AC, you must pay $549.

How is it? Does this large window AC meet your requirements? If not, the Medium AC 8,000 with WhisperTech might be the right choice because you prefer the smaller version.
