10 Best Quiet Ac Window Units 2026 in the United States

The LG 12,200 BTU window air conditioner is a strong choice if you need to cool a medium-sized room up to about 570 square feet. It offers a good cooling capacity suitable for typical living rooms or bedrooms. Noise-wise, it performs well, running quietly at around 50-51 decibels on its low setting, which means it won't be too disruptive for daily use or sleeping. The unit also features supplemental heating, giving you extra warmth during cooler days, which adds versatility beyond just cooling.

With two fan speeds and simple electronic controls plus a remote, adjusting temperature and airflow is straightforward. Energy efficiency is decent, with a SEER rating of 11.3, so it won’t cause excessive power bills, though it doesn't have a top-tier energy star rating. Installation fits standard window sizes with a slide-in/out chassis, making setup manageable but it’s a bit bulky at almost 24 inches wide and weighs 93 pounds, so it may require help during installation.

Additional perks like an auto-restart after power loss, a dust filter, and filter cleaning reminders keep maintenance easier. On the downside, the noise level while low might still be noticeable in very quiet rooms, and it only offers two cooling speeds, which limits fine-tuning comfort. Also, the warranty is fairly standard at one year. For those seeking a reliable, reasonably quiet, and multi-functional window AC unit mainly for medium spaces, this LG model represents a practical option.

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 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.
