10 Best Quiet Window Ac 2026 in the United States

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 Whirlpool WHAW242CW is a strong choice if you need a window air conditioner for a large space up to 1,500 square feet, like a big living room or apartment. Its 24,000 BTU cooling capacity means it can efficiently cool large rooms, and it also handles dehumidification well, removing 6.5 pints of moisture per hour to keep indoor air comfortable. One thing to note is its noise level of 62 dB, which is average for a unit of this size—not the quietest on the market, but generally acceptable for most living spaces. Energy efficiency is decent with a SEER rating of 10.4, which helps manage your electricity costs without compromising performance.

Installation is fairly straightforward if you have a window at least 19.5 inches high and a 230V power outlet, which is less common than standard 115V outlets—this could limit where you can place it unless your home supports this voltage. The unit includes user-friendly features like a remote control, digital display, three cooling speeds, an eco mode, sleep mode, and a 24-hour timer, giving you good control over your comfort and energy use. Maintenance is made easier by a replaceable filter with a Clean Alert system to remind you when it needs attention.

This Whirlpool model fits well for large rooms requiring powerful cooling with flexible settings, though it might not be the best option if you prioritize a very quiet unit or if your home lacks the required 230V outlet.

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.
