10 Best 115 Volt Air Conditioners 2025 in the United States

The Midea 12,000 BTU Smart Inverter Air Conditioner is a versatile window unit designed to cool spaces up to 550 square feet, making it a good choice for larger rooms or small apartments. It offers strong cooling power with a seasonal energy efficiency ratio (SEER) of 13.3, which means it runs more efficiently than many standard models and can help save on electricity bills. The inverter technology allows the unit to adjust its cooling speed, providing consistent comfort while using less energy. It also has a heating function and dehumidifier, which adds value by offering year-round use, although the heat feature won’t work if the outside temperature drops below 41°F.

Operating noise is relatively low at around 45 to 58 decibels, so it won’t be very disruptive whether you’re working, watching TV, or sleeping. Installation is straightforward for double-hung windows within the specified size range, and the unit comes with an installation kit and remote control. Additional smart features include WiFi connectivity and voice control through Alexa or Google Assistant, which is handy for modern homes.

On the downside, the unit weighs 58 pounds, which can make installation a bit challenging for one person. Also, while the noise level is low for an AC, some users might still find it noticeable during quiet nights. The heat pump function’s limitation in cold weather means it’s not a complete replacement for a dedicated heater in colder climates. This model effectively blends efficiency, multiple functions, and smart controls, making it a solid option for those wanting more than just basic cooling from a window air conditioner.

The LG LW1424RD is a robust window air conditioner with a cooling power of 14,000 BTU, making it suitable for cooling medium-sized rooms of up to 800 square feet. Its dimensions are compact at 23.63” W x 15” H x 22.2” D, ensuring it fits well in most windows. One of its key strengths is the quiet operation, with a noise level of 56 dB, making it less disruptive compared to other models.

The unit also features electronic controls and three cooling and fan speeds, which can be easily adjusted using the included remote control. The Auto Restart function is particularly handy, as it automatically turns the unit back on after a power failure, ensuring consistent cooling. Additionally, the 24-Hour Digital On/Off Timer allows users to set a cooling schedule for convenience and energy efficiency. The device includes a slide-out washable filter, which is easy to maintain and comes with a Check Filter alert to remind you when it needs cleaning.

However, the unit's Energy Efficiency Ratio (EER) of 11.2 is decent but not the highest available, and it does not have an Energy Star rating, meaning there are more energy-efficient options out there. At 82 pounds, it's relatively heavy, which might make installation a bit cumbersome without assistance. The air conditioner also includes a dehumidifying feature, which can be beneficial in humid climates. The LG LW1424RD is a solid option for those needing efficient cooling for a medium-sized room, though there are more energy-efficient models available if that is a primary concern.

The LG 12,000 BTU Smart Window Air Conditioner is a solid choice for cooling medium to large rooms up to 550 square feet, making it well suited for spaces like kitchens or living rooms. It offers three fan speeds and an auto-cool option, giving you good control over airflow and temperature. One helpful feature is the LG ThinQ app compatibility, allowing you to control the unit remotely via your phone or voice commands with Alexa and Google Assistant, which adds convenience if you're often on the move at home.

In terms of energy efficiency, it has a Seasonal Energy Efficiency Ratio (SEER) of 12, which is decent but not the highest in its class, so it’s reasonably efficient but might not save the most on electricity compared to some other models. Noise-wise, it operates as quietly as 52 decibels on low mode, so it won’t be too distracting whether you’re relaxing or working. Installation is straightforward since it’s a window unit and includes a kit to help set it up. Additional useful features include a dehumidifier function, a dust filter with a light reminder for cleaning, and an auto-restart after power outages, which means it will turn back on automatically without manual intervention.

One limitation is the one-year warranty, which is standard but somewhat short compared to some competitors offering longer coverage. Also, it requires 115 volts power, so it fits typical US home outlets but should be double-checked for compatibility. This air conditioner blends smart features with solid cooling ability, making it a good fit if you want convenient remote control and reliable performance for medium-sized rooms without breaking the bank.
