10 Best Quiet Ac Window Units 2026 in the United States

The Midea MAW08V1QWT is designed with quiet operation in mind, producing just 32 decibels of noise, which is much quieter than many traditional window AC units. Its unique U-shaped design not only helps reduce noise by using your window as a sound barrier but also allows you to open your window for fresh air without removing the unit. This is a great feature if you value ventilation along with cooling.

With 8,000 BTU cooling power, it efficiently cools rooms up to about 350 square feet, making it suitable for medium-sized bedrooms or living spaces. The advanced inverter technology boosts energy efficiency, saving over 35% on power compared to standard models, and it has earned an ENERGY STAR certification, which means lower electricity bills. Installation is straightforward with the included bracket, fitting most single- or double-hung windows between 22 and 36 inches wide.

The unit also supports smart features like Wi-Fi control and voice commands through Alexa or Google Assistant, which adds convenience if you like managing devices from your phone or smart home system. Additional perks include a built-in dehumidifier and dust filter to improve air quality. However, the unit weighs about 56 pounds, so it might require help during installation. Quieter and more energy-efficient than many competitors, this model is ideal for medium-sized rooms but may not be powerful enough for larger spaces. If you want a quiet, energy-saving window AC with some smart features and an easy installation, this Midea model is a solid choice.

The Midea MAW12V1QWT stands out as a quiet and energy-efficient window air conditioner, making it a strong choice for anyone needing cooling in spaces up to about 550 square feet. Its unique U-shaped design not only helps reduce noise significantly, operating as quietly as 32 dB (which is much lower than typical window AC units), but also allows you to keep your window open for fresh air and a better outside view. This design also comes with an anti-theft lock feature for added security.

With a cooling capacity of 12,000 BTU, this unit is suitable for medium-sized rooms like living rooms or offices. Thanks to its advanced DC inverter technology and R32 refrigerant, it offers over 35% energy savings compared to traditional models and holds an ENERGY STAR certification, which means lower electricity bills and a greener operation. Installation is made straightforward with the included quick-snap bracket, fitting most single or double-hung windows 22 to 36 inches wide and at least 13.75 inches high. The product includes convenient features like remote control, a dust filter, a dehumidifier function, and fast cooling.

The unit weighs around 59 pounds, which might make installation tricky without help. Also, while the noise level is low during operation, some users might find occasional inverter hum. It requires a standard 115V power outlet and uses zinc carbon batteries for the remote, which may need occasional replacement. If you want a quiet, energy-efficient window AC with smart controls and flexible installation for medium-sized rooms, the Midea MAW12V1QWT is worth considering. Just ensure your window size fits and be prepared for moderate installation effort.

The LG 14000 BTU Window Air Conditioner is designed to cool large rooms up to 800 square feet, making it a solid choice for bigger spaces. It operates at around 53 decibels, which is relatively quiet for its size, so it won’t be too distracting in most home or office settings. Its cooling power is strong enough for one large room, and it uses an energy-efficient SEER rating of 11.2, helping keep electricity costs reasonable.

Installation is user-friendly with a slide-in/out chassis and a complete window kit, fitting double hung windows between 27 to 39 inches wide and 16 inches high. This makes it manageable for most standard windows without professional help. The unit also offers modern conveniences like WiFi control via the LG ThinQ app, plus voice command compatibility with Google Assistant and Amazon Alexa — useful if you want to adjust settings without getting up. Maintenance is straightforward thanks to a washable dust filter which helps improve air quality and maintain efficiency. The added dehumidifier feature can enhance comfort in humid environments.

Weighing 82 pounds, it’s a bit heavy and might require two people to install safely. While 53 decibels is quiet for this type of AC, it’s not the absolute quietest model available if you prioritize near-silent operation. The 1-year limited warranty is standard but might feel short for some buyers. This LG unit balances strong cooling, decent quietness, and handy smart features, making it a great fit for those needing to cool larger rooms with easy installation and modern control options.
