10 Best Quietest Window Air Conditioner 2025 in the United States

The Amazon Basics 5000-BTU window air conditioner is a solid choice for cooling small rooms up to 150 square feet, such as bedrooms or home offices. With a cooling capacity of 5000 BTU, it can efficiently handle these spaces without using too much energy, featuring a respectable Energy Efficiency Ratio (SEER) of 14. One of its main advantages is quiet operation, producing noise levels around 56 dB, which is fairly low for a window AC and suitable for sleeping or working.

It offers simple mechanical controls with 7 temperature settings and 2 fan speeds, allowing you to customize comfort easily. The unit also includes a washable filter that helps trap dust and allergens, making maintenance straightforward and helping keep air quality better. Installation is designed to be convenient, fitting standard windows between 23 and 36 inches wide with an adjustable window kit and mounting hardware included; however, you will need a screwdriver yourself.

The noise level isn’t the absolute quietest available—some models can be quieter if silence is your top priority. Also, it only offers two fan speeds, which might limit fine-tuning airflow for some users. Given its modest size and power, it’s best suited for small rooms rather than larger living areas. This model presents a budget-friendly, user-friendly option for anyone seeking a reliable, quiet air conditioner for smaller spaces without complicated features or high energy bills.

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 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.
