10 Best Quiet Window Ac 2025 in the United States

The Midea 8,000 BTU U Shaped Smart Inverter Window Air Conditioner stands out as an ultra-quiet window AC, making it a good choice for those sensitive to noise. It operates at a noise level as low as 42 dB, thanks to its U-shaped design that uses the window to block outside noise. This design not only ensures quiet operation but also allows you to open the window for fresh air, a unique feature among window AC units. The cooling capacity of 8,000 BTU is suitable for spaces up to 350 sq. ft., making it ideal for small to medium-sized rooms.

The unit is energy-efficient, boasting a SEER of 15 and achieving over 35% energy savings compared to traditional units, which contributes to lower electricity bills. It also has the ENERGY STAR Most Efficient certification, indicating top-notch energy performance. The installation is user-friendly with a quick-snap bracket, though it requires specific window dimensions (22''-36'' width and 13.75'' minimum height), which might not fit all window types. The smart control feature allows you to operate the AC via a smartphone app or voice commands using Alexa or Google Assistant, adding convenience to its operation.

Additional features such as a dust filter, fast cooling, and a dehumidifier enhance its functionality. The main downside might be its weight of 55.6 pounds which makes installation a bit cumbersome for one person.

The Frigidaire 12,000 BTU Window Air Conditioner is a solid choice for cooling rooms up to 550 square feet, making it suitable for medium to larger bedrooms or living areas. It offers customizable comfort with six-way directional airflow and three fan speeds, allowing you to direct cool air where you want it most. The unit operates quietly at about 57 decibels, which is relatively low for this power level, so it won’t be too distracting in quiet settings like bedrooms or home offices.

Energy efficiency is decent, with a Seasonal Energy Efficiency Ratio (SEER) of 10.9, and features like Eco and Sleep Modes help reduce electricity use without sacrificing comfort. While it isn’t Energy Star certified, it still provides useful energy-saving functions. Installation is straightforward for a window AC, and the included window kit and washable dust filter make maintenance easy. The remote control adds convenience, so you don’t have to get up to adjust settings.

Some drawbacks include its weight—over 60 pounds—which might require two people for installation. Also, although quiet, some users may notice the fan noise depending on room characteristics. The one-year warranty is standard but may feel short if you want long-term coverage. This Frigidaire unit is well suited for anyone who needs quiet, reliable cooling for medium-sized rooms and values easy controls and energy savings without paying extra for premium certifications.

The Midea 10,000 BTU U Shaped Smart Inverter Window Air Conditioner is designed for those who want a quiet and energy-efficient cooling solution for rooms up to 450 square feet. Its standout feature is the unique U-shaped design that fits into your window while allowing it to stay open, letting fresh air in and preserving your view—a rare benefit among window ACs. This design also helps block outside noise, contributing to its ultra-quiet operation at about 42 dB, which is noticeably quieter than many traditional units.

In terms of cooling power, its 10,000 BTU capacity is suitable for medium-sized rooms, offering fast and effective cooling. The inverter technology not only reduces noise but also saves over 35% energy compared to regular window units, earning it a 5-star Energy Star rating. This means it can cool your space efficiently without running up your electricity bill. Setting up the AC is fairly straightforward thanks to the included quick-snap bracket and support for single or double-hung windows between 22 to 36 inches wide. It also comes with handy features like a dust filter, dehumidifier, and remote control. For smart home enthusiasts, it supports Wi-Fi control and voice commands via Alexa or Google Assistant.

Some users might still find 42 dB noticeable in very quiet environments despite the low noise level. The unit is a bit bulky at nearly 57 pounds, so installation may require some help. Also, it’s designed for standard-sized windows, so it might not fit smaller or unusually sized ones. For those seeking a quiet, energy-saving window AC with modern smart controls and the convenience of an open window, the Midea U Shaped model offers a well-balanced combination of noise reduction, cooling power, and energy efficiency, especially suited for medium-sized rooms.
