10 Best Quiet Ac Window Units 2026 in the United States

The LG 18,000 BTU Heat and Cool Window Air Conditioner is a solid choice for medium to large rooms up to 1,000 square feet. Its cooling capacity is strong, making it effective for maintaining comfortable temperatures in sizable spaces. The unit also doubles as a heater, which is great if you want year-round use from one device. With a noise level of about 57 decibels, it is reasonably quiet but might still be noticeable in very quiet environments, so if ultra-silent operation is a priority, this could be a minor drawback.

Energy-wise, it has a Seasonal Energy Efficiency Ratio (SEER) of 11.1, offering decent efficiency but not the top tier. This means it should keep energy costs moderate but may not be the most economical option long term. The size is fairly large (around 30.5 x 25.5 x 16.8 inches), so installation needs a suitable window and some space.

One of the standout features is the smart control system with WiFi, allowing remote operation through a phone or voice assistants like Alexa and Google Assistant. This adds convenience if you like controlling your AC from anywhere or setting schedules easily. Additional handy features include auto-restart after power outages and filter light reminders to help maintain the unit. This LG air conditioner is a versatile, smart-equipped unit that offers good cooling and heating for bigger rooms with moderate noise levels. It suits those looking for smart home integration and year-round climate control, though it may not be the quietest or most energy-efficient option in its class.

The Midea MAW08HV1CWT EasyCool is a versatile window air conditioner that offers both cooling and heating, making it suitable for year-round use. With a cooling capacity of 8,000 BTU, it's effective for spaces up to 350 square feet, making it ideal for large rooms. Its noise level is impressively low at 45 dBA, which is a standout feature for those seeking a quiet environment. The unit’s energy efficiency is supported by an Energy Star certification and a Seasonal Energy Efficiency Ratio (SEER) of 14.5, promising energy savings of up to 35% compared to standard units.

It's designed for easy use, featuring a variety of modes and speeds, a convenient LED display, and compatibility with smart home systems like Alexa and Google Assistant. This allows users to control the air conditioner using voice commands or remotely via a smartphone app. The included remote control adds to the accessibility and ease of operation.

For installation, the unit fits double-hung windows with specific width and height requirements, and it comes with an installation kit. At 56 pounds, it's relatively manageable in terms of weight. However, potential buyers should ensure their window dimensions meet the installation criteria. One limitation is the heat pump function, which only operates effectively when outdoor temperatures exceed 41°F. This might limit its heating capability in colder climates. Additionally, while it offers a lot in terms of features, the upfront cost might be higher than basic models, but the energy savings could offset this in the long run.

The Midea MAW08HV1CWT is an excellent choice for those looking for an energy-efficient, quiet, and smart AC option with the added benefit of heating.

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.
