10 Best Quietest Window Air Conditioners 2025 in the United States

The Midea MAW06R1CWT EasyCool 6,000 BTU Window Air Conditioner is a well-rounded option for those seeking a quiet and efficient cooling solution for spaces up to 250 sq. ft. One of its standout features is its low noise level of 52 dB, making it a quiet choice for bedrooms, small living rooms, or home offices. It offers a 3-in-1 functionality with cooling, a three-speed fan for air circulation, and a dehumidifier mode, providing versatile comfort options.

The unit is energy-efficient with a SEER of 12.1, and it includes features like Eco mode and an EasyTimer to help save on energy costs. However, it does not have an Energy Star rating, which might be a consideration for those strictly looking for the most energy-efficient options. Installation is straightforward with included mounting accessories, although a screwdriver is required. Maintenance is simplified with a removable and reusable air filter, which helps keep the air clean.

The unit is controlled via an intuitive LED display and a convenient remote control. While it is relatively lightweight at 38.2 pounds, some users might find the installation process challenging without assistance. The Midea MAW06R1CWT offers a good balance of quiet operation, cooling efficiency, and ease of use, making it a solid choice for small to medium-sized rooms.

The LG 18,000 BTU Window Air Conditioner with Heat is designed to cool medium to large rooms up to around 1,000 square feet, making it suitable for bedrooms, living rooms, or basements. It provides both cooling and heating options, which adds versatility for year-round use. The unit offers two fan speeds, allowing some control over airflow and noise levels. Speaking of noise, it operates at about 61.7 decibels, which is moderately loud compared to some quieter window ACs—this means it might be noticeable if you prefer very silent operation, especially in bedrooms or quiet spaces. The energy efficiency ratio (SEER) is 2.8, which is on the lower side, so it may use more electricity than some more efficient models. Installation requires a special 230/208V plug, which could mean additional setup steps or costs if your home isn’t already equipped for it.

On the plus side, LG includes helpful features like a digital control panel and remote control, a 24-hour timer, auto-restart after power outages, and a washable filter, all of which make operation and maintenance simpler. Its 4-way air deflection helps spread air evenly, improving comfort. The design is fairly large and heavy, so installation might need assistance.

If you want a reliable, multi-functional unit that covers larger spaces and don’t mind a bit of operational noise or added installation needs, this LG model is a solid choice. However, if a very quiet or highly energy-efficient unit is your top priority, there might be better options available.

The Midea 5,000 BTU EasyCool Window Air Conditioner is designed for small rooms up to 150 square feet, making it a good choice for bedrooms, home offices, or small living spaces. It operates at a noise level of 57 dB, which is quieter than many similar units but still noticeable in very quiet environments. With 7 temperature settings and 2 fan speeds, plus 2-way air direction, it offers some flexibility to adjust cooling and airflow to your comfort. Its cooling power is adequate for small rooms but wouldn’t be enough for larger spaces.

Energy efficiency is decent with a CEER of 11.0, helping keep electricity bills lower without sacrificing performance. The unit uses R410A refrigerant and has a reusable air filter, which helps with maintenance and environmental impact. Installation is straightforward for standard windows (23"-36" wide), with all necessary mounting hardware included, though you’ll need a screwdriver, and some window frames might require extra steps like pilot holes.

A downside is that it is not Energy Star certified, which means it’s not the most energy-saving option available. While the noise level is relatively low, it’s not completely silent and might be a bit distracting in very quiet rooms. The mechanical controls are simple and user-friendly, making it easy to operate without technical know-how. This window AC presents a practical and affordable solution for decent cooling in a small room with moderate noise and straightforward installation, though those seeking the quietest or most energy-efficient model might want to explore other options.
