10 Best Quietest Window Air Conditioners 2025 in the United States

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 LG 8,000 BTU Window Air Conditioner is designed to cool rooms up to 350 square feet, making it suitable for medium-sized bedrooms, living rooms, or apartments. A key feature is its quiet operation, with noise levels as low as 53 dB in low mode, which is beneficial for users who need a peaceful environment for sleeping or working. The unit offers flexibility with three cooling and fan speeds, as well as an Auto Cool feature that adjusts airflow based on needs.

Additionally, its energy efficiency ratio (EER) is good but not outstanding, making it moderately efficient in terms of energy consumption. The digital control panel and remote control enhance usability, and the 4-way air deflection allows for customizable cooling direction. Installation and maintenance are simplified by the included window installation kit, slide-out washable filter, and filter light reminder.

A notable drawback is that this model is not Energy Star certified, which might be a concern for those prioritizing energy savings. Auto Restart adds convenience by automatically turning the unit back on after a power outage. The LG 8,000 BTU Window Air Conditioner is a solid choice for anyone looking for a quiet, user-friendly cooling solution with adequate cooling power and moderate energy efficiency, though the lack of Energy Star certification could be a downside for energy-conscious buyers.

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.
