10 Best Quiet Window Ac 2025 in the United States

The TCL H14W35W window air conditioner is a strong choice if you need to cool a medium to large room up to 700 square feet, thanks to its solid 14,000 BTU cooling power. It works quietly at about 38 decibels, which is comparable to a soft conversation and suitable for bedrooms or living spaces where low noise is important. Energy efficiency is decent with a SEER rating of 15, and features like Sleep and Eco modes help reduce power use, which can save on electricity bills over time.

Installing this unit is mostly straightforward if your window fits the size requirements (26-36 inches wide by 16 inches high), but some setups might need extra prep like drilling pilot holes. The package includes a remote control and an easy-to-use app, plus voice control compatibility with Alexa and Google Assistant, making it convenient to operate without needing to get up. It also functions as a fan and dehumidifier, which adds versatility for different weather conditions.

The unit is fairly heavy at nearly 70 pounds, so it might be a bit challenging to handle alone during installation. While the noise level is low, some users might still notice it in very quiet rooms. The unit comes with a one-year warranty, which is standard but not extensive. This TCL model effectively balances powerful cooling, smart features, and quiet operation for those looking for a reliable window AC that can cover larger spaces.

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 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.
