10 Best Quietest Window Air Conditioner 2025 in the United States

The Midea MAW08HV1CWT EasyCool Smart Inverter Air Conditioner stands out for its ultra-low noise performance, operating at just 45 dB. This makes it an ideal choice for those seeking a quiet environment, whether for sleeping, working, or relaxing. Its cooling capacity of 8,000 BTU is sufficient for rooms up to 350 square feet, making it a versatile option for bedrooms or medium-sized living spaces. Additionally, its energy efficiency is notable with a SEER rating of 14.5 and Energy Star certification, promising up to 35% energy savings compared to standard models.

This air conditioner also offers multi-season functionality with both cooling and heating capabilities, providing comfort throughout the year as long as the outside temperature exceeds 41°F for heating functions. The unit is user-friendly with an LED display, multiple modes, three-speed settings, a 24-hour timer, and ECO energy saver mode. It can be controlled via a SmartHome App, remote control, or voice commands through Alexa and Google Assistant, adding to its convenience.

Installation requirements are standard for double-hung windows, and the included installation kit makes setup straightforward. Regular maintenance is made easy with a washable filter accessible from the front panel. However, at 56 pounds, the unit is relatively heavy, which might make installation a bit challenging for some users. Additionally, while it provides excellent energy efficiency and quiet operation, the heating function has its limits based on outside temperature. This air conditioner is best suited for users who prioritize quiet operation and energy savings, combined with the convenience of smart controls and multi-season use.

The Midea 6,000 BTU Window Air Conditioner is a solid choice for cooling smaller rooms up to 250 square feet, such as bedrooms or offices. Its noise level at 52 decibels on low mode makes it a relatively quiet option, which is important if you want a peaceful environment. The 3-in-1 functionality means it can cool, fan, or reduce humidity, giving you some flexibility depending on the conditions. You get three fan speeds to choose from, allowing you to adjust airflow to your comfort.

Installation is straightforward if your window frame fits the size range (23"-36" wide and 14" high), with all mounting accessories included—though you’ll need a screwdriver and possibly to drill pilot holes for a secure fit. The unit features an easy-to-use remote control and a reusable air filter that helps keep dust and pet hair out of your air. While the energy efficiency ratio (SEER 12.1) is decent, this model does not have the Energy Star rating, so it might not be the most energy-saving choice available. However, eco mode and a timer help you save on electricity bills.

This Midea window AC is well suited for those looking for quiet, multi-function cooling in a compact unit without complex installation. The one-year limited warranty is fairly standard but not particularly long.

The LG 18,000 BTU Window Air Conditioner is designed to cool large rooms up to 1,000 square feet, making it suitable for medium-sized spaces. It operates at a noise level of 61 dB, which is relatively quiet for its capacity, but may not be the quietest option available. This model offers three cooling and fan speeds with an Auto Cool feature, which allows for customized airflow to suit your comfort needs. The unit is equipped with electronic controls and comes with a remote, enabling you to adjust settings from across the room easily.

Additionally, it includes a 24-hour on/off timer and a 4-way air deflection system for optimal air distribution. The Auto Restart function is a handy feature that ensures the air conditioner resumes its previous settings after a power outage, providing convenience and peace of mind. Maintenance is straightforward with a filter light reminder that prompts you to clean the washable filter, helping maintain the unit's efficiency.

With a SEER of 10.3, it is not the most energy-efficient model on the market, and it is not Energy Star rated. Installation should be manageable using the included installation kit, though the unit's weight of 130 pounds may require assistance. This air conditioner is a reliable choice with several practical features, but it may not be the top pick if ultra-quiet operation and high energy efficiency are your primary concerns.
