10 Best Quiet Ac Window Units 2025 in the United States

The Midea MAW08HV1CWT EasyCool is a versatile window air conditioner that offers both cooling and heating, making it suitable for year-round use. With a cooling capacity of 8,000 BTU, it's effective for spaces up to 350 square feet, making it ideal for large rooms. Its noise level is impressively low at 45 dBA, which is a standout feature for those seeking a quiet environment. The unit’s energy efficiency is supported by an Energy Star certification and a Seasonal Energy Efficiency Ratio (SEER) of 14.5, promising energy savings of up to 35% compared to standard units.

It's designed for easy use, featuring a variety of modes and speeds, a convenient LED display, and compatibility with smart home systems like Alexa and Google Assistant. This allows users to control the air conditioner using voice commands or remotely via a smartphone app. The included remote control adds to the accessibility and ease of operation.

For installation, the unit fits double-hung windows with specific width and height requirements, and it comes with an installation kit. At 56 pounds, it's relatively manageable in terms of weight. However, potential buyers should ensure their window dimensions meet the installation criteria. One limitation is the heat pump function, which only operates effectively when outdoor temperatures exceed 41°F. This might limit its heating capability in colder climates. Additionally, while it offers a lot in terms of features, the upfront cost might be higher than basic models, but the energy savings could offset this in the long run.

The Midea MAW08HV1CWT is an excellent choice for those looking for an energy-efficient, quiet, and smart AC option with the added benefit of heating.

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 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.
