10 Best Quiet Ac Window Units 2026 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 18,000 BTU Heat and Cool Window Air Conditioner is a solid choice for medium to large rooms up to 1,000 square feet. Its cooling capacity is strong, making it effective for maintaining comfortable temperatures in sizable spaces. The unit also doubles as a heater, which is great if you want year-round use from one device. With a noise level of about 57 decibels, it is reasonably quiet but might still be noticeable in very quiet environments, so if ultra-silent operation is a priority, this could be a minor drawback.

Energy-wise, it has a Seasonal Energy Efficiency Ratio (SEER) of 11.1, offering decent efficiency but not the top tier. This means it should keep energy costs moderate but may not be the most economical option long term. The size is fairly large (around 30.5 x 25.5 x 16.8 inches), so installation needs a suitable window and some space.

One of the standout features is the smart control system with WiFi, allowing remote operation through a phone or voice assistants like Alexa and Google Assistant. This adds convenience if you like controlling your AC from anywhere or setting schedules easily. Additional handy features include auto-restart after power outages and filter light reminders to help maintain the unit. This LG air conditioner is a versatile, smart-equipped unit that offers good cooling and heating for bigger rooms with moderate noise levels. It suits those looking for smart home integration and year-round climate control, though it may not be the quietest or most energy-efficient option in its class.

The Midea MAW08V1QWT is designed with quiet operation in mind, producing just 32 decibels of noise, which is much quieter than many traditional window AC units. Its unique U-shaped design not only helps reduce noise by using your window as a sound barrier but also allows you to open your window for fresh air without removing the unit. This is a great feature if you value ventilation along with cooling.

With 8,000 BTU cooling power, it efficiently cools rooms up to about 350 square feet, making it suitable for medium-sized bedrooms or living spaces. The advanced inverter technology boosts energy efficiency, saving over 35% on power compared to standard models, and it has earned an ENERGY STAR certification, which means lower electricity bills. Installation is straightforward with the included bracket, fitting most single- or double-hung windows between 22 and 36 inches wide.

The unit also supports smart features like Wi-Fi control and voice commands through Alexa or Google Assistant, which adds convenience if you like managing devices from your phone or smart home system. Additional perks include a built-in dehumidifier and dust filter to improve air quality. However, the unit weighs about 56 pounds, so it might require help during installation. Quieter and more energy-efficient than many competitors, this model is ideal for medium-sized rooms but may not be powerful enough for larger spaces. If you want a quiet, energy-saving window AC with some smart features and an easy installation, this Midea model is a solid choice.
