How Does the Windmill AC Work?

The Windmill AC is designed to be the ultimate modern window air conditioner. Featuring advanced technology, a mobile app, and an easy-to-install design, the Windmill AC aims to change the way you cool your home and keep indoor air clean.

Each Windmill AC order includes everything you need to install it, including the tools, insulation foam, and more. Even if you have no handyperson skills or experience, you should be able to easily install the Windmill AC on your home.

Once installed, the Windmill AC works similar to other inverter window-based AC systems:

In inverter air conditioners, you adjust temperature by changing the motor speed of the inverter, allowing you to maximize cooling power and minimize electricity consumption

You control the Windmill AC using a remote control or mobile app, choosing from 3 fan speeds and 3 cooling settings

Each Windmill AC uses advanced inverter technology and a near-silent linear fan, making it 9x quieter and 35% more efficient than legacy, non-inverter ACs

To make the Windmill AC even more efficient, Windmill Air uses a special, eco-friendly type of refrigerant; this refrigerant accelerates the cooling power of the Windmill AC, allowing your home to stay cooler and more comfortable

As air passes through the Windmill AC, it also passes through an activated carbon filter and antimicrobial mesh filter. These two filters cleanse the air of certain contaminants. You replace the activated carbon filter roughly every 3 months, and you wash the antimicrobial mesh filter as needed.

Overall, the combination of inverter AC technology, refrigerant, and filters makes the Windmill AC the ultimate window-based air conditioner on the market. With a combination of traditional AC experience with modern technology and contemporary design, the Windmill AC aims to exceed your expectations for a window AC unit.

Windmill AC Features

Windmill AC Features

The Windmill AC is designed to be the iPhone of window air conditioners. It has many features to make it better than competing AC units while achieving the ultimate cooling for your home.

Here are some of the features you can enjoy with each Windmill AC:

Easy to Install: The Windmill AC is specifically designed to be easy to install, and most of the air conditioner already arrives pre-assembled in the box. In comparison, other window air conditioners may require hours of work to install.

Blows Air Into Room at 45 Degree Angle for Better Cooling: Some window air conditioners blow air straight into your home, which isn’t efficient for cooling temperatures. The Windmill AC works differently, blowing air into your house at a 45-degree angle for better cooling. When air blows towards the ceiling, it makes it easier to cool your entire home. Otherwise, only the lower half of your home will be cool, and warm air rises to make the upper half an uncomfortable temperature (or putting excess strain on your air conditioner).

Control with Mobile App: The Windmill AC is a smart air conditioner because you can control it with a mobile app. The Windmill AC mobile app is available for Android and iOS devices. You can control the temperature, speed, and other settings from your phone.

Comes with Remote Control: You don’t need to use the Windmill AC mobile app. Instead, you can use the remote control to customize temperature and speed settings.

Eco-Friendly: Windmill Air helps offset the carbon footprint of every Windmill AC you purchase. Carbon offset is included for free with all Windmill AC purchases.

Includes Everything You Need to Install Windmill AC Today: Your Windmill AC box includes the Windmill AC and a complete installation kit, including cosmetic side panels, two types of insulation foam, scissors, window lock, and other installation hardware and accessories. Even if you have no tools and you’re not handy, you should have no issue installing Windmill AC.

Ultra Quiet Design: Some Windmill ACs use WhisperTech technology to cool your home while being ultra-quiet. According to Windmill Air, this technology allows the air conditioner to be “9x quieter than legacy non-inverter ACs,” helping your home stay cool without excessive noise.

Advanced Inverter Technology: Some cheap AC units simply blow air across your home to keep it cool. Others use ineffective water curtains or water tanks. The Windmill AC, meanwhile, uses advanced inverter technology to physically lower the temperature of incoming air before spreading it into your home.

Ultra Efficient: According to Windmill Air, each Windmill AC is 35% more efficient than legacy non-inverter ACs, which means you could save hundreds on utility bills over a summer.

Dual Air Intake: Windmill AC uses dual air intake for better cooling.

3 Cooling Settings: Windmill AC has 3 cooling settings, including low, medium, and high.

3 Fan Speeds: Windmill AC also has 3 fan speeds, including low, medium, and high.

Auto Dimming LED Display: Each Windmill AC has an LED display that automatically dims. You can view important information about your Windmill AC from the LED display.

Free Activated Carbon Filter: Each Windmill AC comes with a free activated carbon filter. Activated carbon filters are effective for removing certain volatile organic compounds (VOCs) from the air, improving indoor air quality. The Windmill AC’s activated carbon filter should be replaced roughly every 3 months, depending on air quality. You can subscribe to an activated carbon filter subscription program directly through Windmill AC.

Reusable Antimicrobial-Protected Mesh Filter: In addition to having a single activated carbon filter inside, the Windmill AC has a reusable antimicrobial-protected mesh filter. You simply wash that filter periodically to keep your Windmill AC running efficiently.

Adhesive & Non-Adhesive Window Insulation Foam: Your Windmill AC assembly kit comes with two types of insulation foam, including adhesive and non-adhesive window insulation foam.

2x Energy Star Required: Windmill AC features double-sided installation, beating Energy Star requirements two times over.

Control your AC from Anywhere: Because the Windmill AC works with the app, you can control your AC from anywhere. If you want to start cooling your home an hour before you arrive back from vacation, for example, then you can do that using the Windmill AC app. Or, you can turn off the Windmill AC after leaving the house if you forgot.

Works with Google Assistant and Amazon Alexa: The Windmill AC connects with Google Assistant and Amazon Alexa for voice control, allowing you to control temperature and speed settings through your smart home system.

Fits Most Single or Double-Hung Windows: Each Windmill AC fits most single or double-hung windows. As long as your window has an opening width of 23 to 37 inches (8,300 BTU AC) or 22 to 36 inches (6,000 BTU AC) and a vertical opening of at least 14 inches (8,300 BTU AC) or 13 inches (6,000 BTU AC), it should work with the Windmill AC.

Easily Cools Small & Medium-Sized Rooms: The Windmill AC is ideal for cooling rooms up to 250 square feet (with the 6,000 BTU model) or 350 square feet (with the 8,300 BTU model).

Earn Eco Rewards Via the App: The Windmill AC offers an Eco Rewards program in select areas, including parts of New York and California. The first-of-its-kind rewards system helps you use less electricity when it matters most – like during a heatwave. You enroll via the app, then earn rewards for certain cooling behavior.

Responsible, Eco-Friendly Refrigerant with Less Global Warming Potential: Many window-based AC units use a refrigerant known to be harmful to the environment and contribute to climate change called R410a. Windmill Air took a different approach, using a responsible, eco-friendly refrigerant called R32 with 68% less global warming potential than R410a.

Backed by 30 Day Risk Free Guarantee: All Windmill AC purchases come with a risk-free 30 day guarantee. You can request a complete refund on your purchase within 30 days with no questions asked if you’re unsatisfied for any reason.

TaskRabbit Installation Available: Anyone can install the Windmill AC into their home with no additional tools or experience. However, if you want extra help, you can use TaskRabbit. Windmill Air partnered with TaskRabbit nationwide to help you find someone qualified to install your air conditioning system.

Premium Installation Available: Windmill Air also offers premium installation services in New York City. Premium installation includes custom plexiglass and city-compliant installations performed by professional technicians.

Windmill AC vs. Traditional ACs

The Windmill AC is designed to be the ultimate window-based air conditioning system. The founders of Windmill Air developed Windmill AC based on 60+ years of family air conditioning experience, combining that experience with modern technology.

Here are some of the differences between the Windmill AC and traditional or new AC systems:

The Windmill AC has superior design, and the modern look fits with many modern interiors and decorating styles.

The Windmill AC is easy to install with no additional tools required. It comes pre-assembled, and you can easily install the Windmill AC even if you have no technical expertise or experience.

The Windmill AC is better for the environment. Windmill Air offsets all carbon emissions for each purchase. Plus, you can earn Eco Rewards for energy-efficient AC usage – like limiting usage during heatwaves.

The Windmill AC improves indoor air quality with its activated carbon filter. Many air conditioners simply cycle air through your home without filtering it, and you may be breathing in dirty (but cool) air. With the Windmill AC, you can relax knowing your indoor air is clean and cool.

You can control the Windmill AC via Wi-Fi, remote control, and a mobile app. In comparison, many other AC systems have basic remote controls or panel-based control systems.

The Windmill AC offers superior insulation for maximum efficiency, featuring double-insulating side panels.

The WhisperTech technology on the Windmill AC keeps your home cool without making excessive noise, which is much different than other noisy systems available toady.
