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 LG 12,000 BTU Window Air Conditioner is a solid choice if you’re looking for a quiet unit that cools medium-sized rooms up to 550 square feet, such as bedrooms, living rooms, or small apartments. It operates at about 52-53 decibels on its lowest setting, which is fairly quiet for a window AC and should let you work or sleep comfortably without much disturbance. It offers three fan and cooling speeds, so you can adjust airflow to your liking and use the auto cool mode for easy temperature maintenance. The digital control panel and remote control add convenience, while the 24-hour timer helps save energy by letting you schedule when the unit runs.

Installation is made easier with the included window kit and slide-out washable filter, which also reminds you when it needs cleaning. The energy efficiency ratio (SEER) is 13, which is decent but not top-tier, so the unit balances performance and running cost moderately well. One downside is that it lacks a formal energy star or BEE star rating, which means it might not be the most efficient compared to some newer models. Also, the unit weighs 81 pounds, so it might require some help during installation.

The 1-year warranty covers parts and labor, giving some peace of mind. With generally positive customer ratings around 4.2 out of 5 stars, this LG model is a reliable pick if quiet operation and customization are your priorities, though if energy savings are your top concern, you might find alternatives with higher efficiency ratings.

The Midea MAW08V1QWT stands out for those looking specifically for a quiet window air conditioner. Thanks to its unique U-shaped design, it blocks outside noise and operates as quietly as 32 decibels, which is very low compared to typical units. This makes it ideal for bedrooms or offices where noise can be a distraction. It provides 8,000 BTU cooling power, suitable for rooms up to about 350 square feet, making it a good fit for small to medium rooms.

Another plus is its energy efficiency—using advanced inverter technology, it saves more than 35% energy compared to standard models and holds an ENERGY STAR certification, so you can expect lower electricity bills. The unit also offers convenient smart features like Wi-Fi control and compatibility with Alexa and Google Assistant, allowing you to adjust settings from your phone or voice commands. Installation is relatively simple with the included bracket and fits various window types, plus the window can stay partially open for fresh air even when the AC is running.

The unit weighs over 55 pounds, which might require some help during installation. Although quiet, the airflow options are limited to two speeds, which might restrict fine-tuning comfort levels. Also, while it covers average room sizes, it may not be powerful enough for larger spaces. This air conditioner represents a solid choice for those who prioritize peace and energy savings in a compact, smart-controlled package.
