10 Best Window Air Conditioners 2025 in the United States

The Midea 12,000 BTU Smart Inverter Air Conditioner is a solid choice for cooling (and heating) rooms up to 550 square feet, making it suitable for larger bedrooms or living areas. Its inverter technology helps save energy by running efficiently and quietly compared to many standard units. With an Energy Star rating and a cooling efficiency ratio (SEER) of 13.3, it offers noticeable savings on electricity bills. Noise levels are quite low for an air conditioner, so it won't disturb conversations or sleep, operating around 45 to 58 dB depending on settings.

Installation fits most double-hung windows with specific size requirements, and the unit comes with all necessary mounting kits and a remote control for easy use. A key highlight is the multi-season functionality—it includes heating and dehumidifying modes, which extend its usefulness beyond summer. Smart features like app and voice control add convenience if you want to adjust settings remotely. One limitation is that the heat function may not work well in very cold weather (below 41°F outside). Also, while it’s quieter than many models, some users might still notice noise at higher speeds.

The unit is reasonably compact but quite heavy, so installation might require some assistance. This Midea model provides a good balance of power, energy savings, and quiet operation with modern features that cater to year-round comfort.

The Midea MAW12V1QWT is a 12,000 BTU window air conditioner designed to cool rooms up to about 550 square feet, making it a good choice for medium-sized living spaces or offices.

The unit weighs nearly 59 pounds, which might be challenging for one person to install alone. While 12,000 BTUs provide solid cooling power and energy savings, this capacity may not suffice for larger rooms or spaces with poor insulation. The Midea MAW12V1QWT is a strong option for those seeking a quiet, energy-efficient window air conditioner with smart controls and an innovative design fitting most standard windows.
