10 Best Quiet Ac Window Units 2025 in the United States

The Midea MAW12HV1CWT EasyCool Smart Inverter Air Conditioner Window Unit offers both cooling and heating capabilities with a robust 12,000 BTU capacity, making it suitable for large rooms up to 550 square feet. One of its standout features is the ultra-low noise performance, operating as quietly as 45 dB, which makes it an excellent choice for bedrooms or home offices where low noise is crucial.

Energy efficiency is another strong point of this unit, boasting an impressive CEER of 13.3 and being Energy Star certified, which can help save up to 35% on energy costs compared to standard models. The built-in inverter technology ensures that it uses electricity efficiently, contributing to the cost savings and environmental benefits. Installation is straightforward for double-hung windows with the required dimensions and comes with an installation kit for convenience.

The unit's smart features, including WiFi connectivity, allow you to control it via a smartphone app, Alexa, or Google Assistant, adding a layer of convenience to its operation. However, it has some drawbacks. The heating function is limited and will not work if the outside temperature is below 41°F, which might be a concern for those in colder climates. Additionally, while the noise level at its quietest is very low, the maximum noise level can reach up to 58 dB, which may still be noticeable in some settings. The unit is relatively heavy at 58 pounds, which might make installation a bit challenging for some users. Despite these minor drawbacks, this Midea unit excels in providing year-round comfort, energy efficiency, and smart home integration, making it a strong candidate for those looking for a multi-functional and quiet window AC unit.

The LG 23,500 BTU Dual Inverter Smart Window Air Conditioner is a strong choice if you need to cool a large space, up to about 1,400 square feet, like a big living room or office. It stands out with its ultra-quiet operation, thanks to the dual inverter technology that keeps noise as low as 44 dB in sleep mode—quiet enough to avoid disturbing your peace. This technology also helps it be 50% more energy efficient than typical Energy Star standards, which means it can save you money on electricity. The unit has a good energy rating (5 stars) and a SEER of 14.5, confirming its efficiency.

In terms of installation, it’s a fairly large unit (about 30" deep by 26" wide), so make sure your window can accommodate it. It runs on 230 volts, which is common for powerful window units. Extra features add convenience: it connects to WiFi, allowing you to control it remotely via the LG ThinQ app or with voice assistants like Alexa and Google Assistant. You also get multiple fan speeds, a dehumidifier function, and reminders for filter cleaning, making maintenance easier.

The size might be a bit bulky for smaller windows, and being a higher capacity unit, it may be more than needed for small rooms, which could lead to less efficient operation in those cases. This LG model offers a quiet, energy-efficient air conditioner with smart controls suitable for large rooms.

The Midea 6,000 BTU Window Air Conditioner is a solid choice for cooling rooms up to 250 square feet, making it suitable for bedrooms, small offices, or studies. It operates quietly at about 52 decibels on low mode, which is relatively gentle compared to louder units, helping maintain a peaceful environment. With a cooling power of 6,000 BTU, it efficiently cools small spaces without using excessive energy, supported by features like Eco mode and a timer to help save electricity. Although it does not have an Energy Star rating, its SEER of 12.1 suggests decent energy efficiency for this class. Installation is straightforward for standard windows, with included mounting hardware, though you might need a screwdriver and some care with pilot holes for best fit.

The unit also acts as a fan and dehumidifier, adding versatility beyond simple cooling. A remote control and LED display make operation easy from across the room, and the reusable air filter helps keep dust and pet hair out of your space. On the downside, the unit is a bit bulky and weighs over 38 pounds, which could make handling and installation a bit challenging for some. The noise level, while quiet enough for most, may still be noticeable in very quiet settings. Also, it lacks advanced smart features found in pricier models.

In summary, the Midea EasyCool is a practical, easy-to-use air conditioner that balances quiet operation, good cooling power, and energy-saving options. It is ideal for those needing a reliable unit for smaller rooms without breaking the bank.
