10 Best 110 Volt Window Air Conditioner 2025 in the United States

The Midea 12,000 BTU Smart Inverter Air Conditioner is a strong choice if you need a window unit that cools large rooms up to about 550 square feet. Its inverter technology helps it cool efficiently and quietly, running at about 45 to 58 dB, which is low enough to not disturb conversations or work from home. It’s also Energy Star rated with a Seasonal Energy Efficiency Ratio (SEER) of 13.3, meaning it uses less electricity than many basic models, potentially lowering your energy bills. The unit stands out by offering heating and dehumidifying functions, making it useful not only in summer but also for mild cold weather—though the heat won’t work if it’s colder than 41°F outside.

Installation requires a standard double-hung window with a specific opening size, and the unit’s size is fairly standard for its power. You also get convenient features like remote control, app control with Alexa and Google Assistant compatibility, and a washable filter for easy maintenance. On the downside, the heating function is limited in very cold climates, and while the noise level is low, some users might find 58 dB a bit noticeable depending on their sensitivity. It weighs 58 pounds, so installation might need some help.

If you want a versatile, energy-efficient air conditioner that also provides heating and can be controlled smartly, this Midea unit is a fitting option. However, if you live in very cold areas or want ultra-quiet operation below 45 dB, you might want to consider other alternatives.

The LG LW1424RD is a solid choice if you need a window air conditioner for medium to large rooms, as it offers a strong cooling capacity of 14,000 BTUs, which can effectively cool spaces up to 800 square feet. This makes it suitable for bigger living rooms or open-plan areas. It operates on standard 115 volts, common for household window units. Its energy efficiency ratio (EER) is 11.2, which is decent, meaning it balances power consumption and cooling ability reasonably well but could be a bit less efficient compared to premium models.

Noise level is around 56 decibels, which is moderately quiet but noticeable, similar to a normal conversation, so it won't be completely silent but generally won’t be disruptive. The unit is fairly compact with dimensions just over 23 inches wide and 15 inches tall, fitting most standard windows, and installation is straightforward for someone comfortable with window ACs. It comes with convenient features like a remote control, electronic controls, a washable filter with an alert to remind you when to clean it, and an auto-restart function that turns the AC back on after power outages. The 3 fan and cooling speeds let you tailor comfort, and a 24-hour timer helps save energy by scheduling operation times.

On the downside, it weighs 82 pounds, which might be heavy for some to install alone, and it lacks a BEE star rating, so it may not be the most energy-saving option available. The included window curtain panels can help with better installation and sealing. Considering its performance and features, this LG unit fits well for users needing reliable, mid-range cooling with some useful modern conveniences, though if you want ultra-quiet operation or top-tier energy savings, you might want to explore other models.

The Midea 12,000 BTU EasyCool Window Air Conditioner is an excellent option for cooling medium-sized rooms or spaces up to about 350 square feet comfortably. It offers a strong cooling capacity suitable for typical rooms or small apartments and features energy-efficient modes such as Eco mode and timer settings to help manage power consumption and reduce electricity bills.

This unit operates at a noise level around 55 decibels, quieter than a refrigerator but still noticeable in very quiet environments. It is easy to install in most standard windows and comes with all necessary mounting accessories, though a screwdriver is required for setup. The size is standard for a window AC, fitting most window frames within the recommended size range.

Additional features include a 3-in-1 function allowing it to cool, dehumidify, or circulate air with a 3-speed fan, plus a remote control for convenient adjustments. The reusable filter helps keep dust and pet hair out of the air. Coverage is best suited for smaller rooms rather than larger open spaces, and the unit includes a one-year warranty. Generally positive reviews highlight its reliable performance for everyday use, making this Midea model a solid, multifunctional, and energy-conscious choice.
