10 Best Quiet Ac Window Units 2025 in the United States

The Frigidaire 12,000 BTU Window Air Conditioner is a solid choice if you need to cool medium to large rooms around 550 square feet. It offers customizable cooling with three fan speeds and 6-way directional airflow, which helps spread cool air more evenly. The unit runs at about 57 decibels, which is on the quieter side for window ACs but not the absolute quietest available. If very low noise is your top priority, there might be quieter options, but this level should be comfortable for most living spaces and bedrooms.

The energy efficiency rating (SEER of 10.9) is decent but it’s not Energy Star certified, so it’s not the most energy-saving model on the market. However, features like Eco Mode and Sleep Mode help reduce electricity use by adjusting cooling based on your needs. Installation is straightforward with the included window kit, and its size fits standard windows without being overly bulky.

Extra perks such as a remote control, a washable dust filter with cleaning alerts, a 24-hour timer, and a Dry Mode to reduce humidity add convenience and comfort. The unit weighs over 60 pounds, so it might require a sturdy window and some help during installation. The one-year warranty is standard but somewhat limited. For those seeking a balance of quiet operation, effective cooling for medium-large rooms, and useful features at a reasonable price, this Frigidaire model is a worthwhile option.

The Frigidaire FHWC063TC1 is a 6,000 BTU window air conditioner designed for cooling small to medium-sized rooms up to 250 square feet. One of its key strengths is its noise level, which is relatively low at 51 dB, making it a quiet option for a peaceful environment. It also offers flexibility with a multi-speed fan that allows you to adjust cooling settings to your preference. The unit is compact, with dimensions of 15.9 x 13.2 x 12 inches, and weighs 38.2 pounds, making it easier to install and fit into most windows without much hassle.

It comes with a convenient remote control, a filter light reminder, and a dust filter, which adds to its user-friendly features. However, it is not Energy Star rated and has a seasonal energy efficiency ratio (SEER) of 11, which means it might not be the most energy-efficient option available. The included components like the window kit and washable filter add to its practicality, and the 1-year manufacturer's warranty provides some peace of mind.

This unit would be ideal for someone looking for a quiet and compact air conditioner with basic features for small spaces. However, if energy efficiency is a top priority, you might want to consider other options.

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.
