7 Best Quiet Window Air Conditioners 2025 in the United States

The Midea MAW08R1BWT EasyCool is a solid choice if you need a quiet window air conditioner for a room up to about 350 square feet. It cools with 8,000 BTUs, suitable for medium-sized spaces like bedrooms or small living rooms. Its noise level is around 55 dB, which is quieter than many older models but still noticeable if you prefer very silent operation.

The unit offers three fan speeds and a 3-in-1 mode that lets you cool, circulate air, or dehumidify, adding flexibility to keep your room comfortable in different weather. Energy efficiency is decent with a SEER rating of 12 and an Eco mode, helping you save on electricity without complicated settings. Installation is straightforward for most standard windows, with all mounting accessories included, though a screwdriver is needed and pre-drilling holes might improve stability.

The reusable air filter is easy to clean, helping maintain air quality and saving money on replacements. An LED display and remote control make adjusting settings convenient from across the room. While the 55 dB noise level is relatively quiet, this air conditioner is not the best option if you require near-silent operation for sleeping. It does not have a star energy rating, which may make efficiency comparisons to other models more difficult. Weighing over 50 pounds, installation might require two people. If you want reliable cooling with simple controls, reasonable noise, and a good balance of features for medium rooms, the Midea EasyCool is a good fit.

The LG 6,000 BTU Dual Inverter Smart Window Air Conditioner is a solid choice if you're looking for a quiet and energy-efficient unit to cool a medium-sized room around 250 square feet. Its standout feature is the ultra-quiet operation, running as low as 44 decibels in sleep mode, which means it won’t disturb your peace or sleep. The Dual Inverter technology also helps it use up to 35% less energy compared to standard units, which can save you money on electricity bills over time. It offers four fan speeds, giving you some flexibility to adjust the airflow and cooling intensity to your comfort. The smart features are a big plus—being able to control the air conditioner remotely through LG’s ThinQ app or via voice commands with Alexa or Google Assistant adds convenience, especially if you want to set the temperature before you arrive home.

Installation is typical for window units and includes window curtain panels, but keep in mind it is designed mainly for rooms no larger than 250 sq. ft. If your space is bigger, it might struggle to cool effectively. The unit also has a dehumidifier function and filter reminder, which helps maintain air quality. On the downside, the warranty is limited to one year, which is shorter than some competing models offer. The size and weight (about 63 pounds) mean you might need some help installing it.

This LG model fits well for anyone wanting a quiet, efficient, moderately sized window AC with smart home features but may not be the best fit for larger rooms or those seeking longer warranty coverage.

The Midea MAW12HV1CWT EasyCool Smart Inverter Air Conditioner is a versatile choice for those seeking both cooling and heating in one unit. With a 12,000 BTU capacity, it's well-suited for large rooms up to 550 square feet. A key strength is its energy efficiency, boasting a 13.3 Energy Efficiency Ratio (EER) and Energy Star certification, which translates to up to 35% energy savings compared to standard units. This can lead to lower electricity bills, making it both an eco-friendly and budget-friendly option. The noise level is another highlight, operating as low as 45 dBA in low settings, ensuring a quiet environment for activities like Zoom calls or watching TV.

The unit comes with multiple fan speeds and modes, including heating, cooling, dehumidification, and fan-only settings, offering flexibility throughout the year. It also features convenient controls via an LED display, remote, and a SmartHome App, as well as voice control through Alexa and Google Assistant, enhancing user convenience. Installation is fairly straightforward, designed to fit double-hung windows with specific dimensions, and includes an installation kit.

However, a notable drawback is that the supplemental heat function doesn’t work if the outside temperature falls below 41°F, which may limit its effectiveness during extremely cold winters. The unit’s noise level at high settings (58 dB) might be noticeable for some users. Maintenance is relatively easy with a washable filter, but the overall weight of 58 pounds might make it slightly cumbersome to install. Despite these minor cons, the Midea MAW12HV1CWT stands out as a reliable, multi-functional air conditioner and heater that suits users looking for a quiet, energy-efficient solution for their large rooms.
