10 Best Quiet Window Ac 2025 in the United States

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.

The LG 12,000 BTU Smart Window Air Conditioner is designed to cool rooms up to 550 square feet, making it suitable for larger spaces like kitchens or living rooms. It offers three fan speeds and an auto cool mode, allowing you to adjust airflow for comfort. Noise-wise, it performs well for a window unit, operating as low as 52 dB on its quiet setting — comparable to a normal conversation, so it won’t be too noisy for most users.

The unit includes smart features such as WiFi control via the LG ThinQ app and compatibility with Alexa and Google voice commands, letting you manage settings remotely or hands-free. It also has practical additions like a 24-hour timer, 4-way air deflection for more even cooling, and an auto restart function after power outages. Its Energy Efficiency Ratio (EER) is 12, which is decent but not top-tier for saving on electricity bills. Also, it’s not Energy Star certified, so it might use more power compared to more efficient models.

The physical size is fairly standard for this cooling capacity, and installation should be straightforward with the provided kit, but at 81 pounds, it might require two people to mount. This LG unit balances good cooling power with quiet operation and smart features, making it a solid choice for those wanting a comfortable, easy-to-control window AC in medium to large rooms, albeit with modest energy efficiency.

The LG LW1223HR window air conditioner is a solid choice for cooling medium-sized rooms up to 570 square feet, such as bedrooms or living rooms. Its 12,200 BTU cooling capacity is well-suited for this space size, delivering effective cooling without being oversized. The noise level of 52 dB is moderately quiet, so it won’t be completely silent but should be acceptable for most users looking for a peaceful environment.

With a Seasonal Energy Efficiency Ratio (SEER) of 11.6, it offers decent energy efficiency that can help keep electricity costs reasonable, though it’s not the most efficient model on the market. The size of the unit (22 x 23.63 x 15 inches) is fairly standard for window ACs, and it comes with window curtain panels to assist with installation. The 1-year warranty is standard but could be longer for better peace of mind.

One of the standout features is its smart connectivity via LG ThinQ technology, allowing you to control the AC remotely through your phone or voice commands with Alexa or Google Assistant — a great convenience for modern homes. Additional perks include multiple fan speeds, heating function, a 24-hour timer, auto restart after power outages, and a built-in dehumidifier. While the noise level might still be noticeable for those extremely sensitive to sound and it lacks a high energy star rating, this LG window AC provides a good balance of cooling power, smart features, and ease of use for medium rooms, especially if you value remote control and voice commands.
