10 Best Quiet Window Ac 2025 in the United States

The Midea 12,000 BTU Smart Inverter Window Air Conditioner is designed for rooms up to 550 square feet, making it a strong choice for larger bedrooms or living spaces. It offers solid cooling power combined with heating and dehumidifying functions, providing comfort through multiple seasons. One of its standout features is the quiet operation, running at about 45-58 dB depending on settings, which means it won't be distracting during work, relaxation, or sleep.

Thanks to its inverter compressor and Energy Star certification, it delivers good energy efficiency with up to 35% savings compared to standard units. The unit is easy to control via a remote, on-device buttons, or smart home apps with voice assistant support, adding convenience. Installation is typical for window units, fitting double-hung windows with specific size requirements, and it includes a washable filter to keep performance steady.

While the noise level is low, some users might still notice it when on higher settings. Also, the heating feature won't work in very cold outdoor temperatures (below 41°F), which limits its use as a heater in colder climates. The size and weight (58 pounds) mean installation might require some effort or assistance. This model is well-suited for those needing a quiet, efficient window AC with added heat and smart features, especially in mild to warm climates.

The Midea 8,000 BTU Smart Inverter Window Air Conditioner is a solid choice for cooling rooms up to 350 square feet, making it suitable for medium-sized bedrooms or living spaces. It stands out with a quiet operation at about 45 decibels, which means it won’t disturb conversations, work calls, or sleep. With its inverter technology, it runs efficiently and can save up to 35% on energy compared to standard units, backed by its Energy Star rating and a SEER of 14.5.

Besides cooling, it also offers heating and dehumidifying functions, adding versatility for year-round comfort, although the heating works best when the outdoor temperature is above 41°F. The unit is user-friendly, featuring multiple modes, an LED display, remote control, and smart home compatibility via WiFi, Alexa, and Google Assistant, making it easy to adjust settings from anywhere. Installation fits most double-hung windows within specific size limits, but the lower sash must open enough to accommodate the unit’s height. Its footprint is fairly compact for a window AC with heat.

This Midea model provides a versatile, energy-saving option for those seeking a quiet air conditioner with heating capabilities, especially in moderately sized rooms. The warranty period is limited to one year.

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.
