10 Best 115 Volt Air Conditioners 2025 in the United States

The LG 12,000 BTU Window Air Conditioner is a solid choice for cooling medium-sized rooms up to 550 square feet, making it ideal for bedrooms, living rooms, and apartments. With its 3 cooling and fan speeds, you can customize the air flow to suit your comfort. One of its standout features is the low noise performance, operating at just 52 dB, which ensures minimal disturbance whether you are working or sleeping.

The unit also includes a digital control panel and remote control, offering convenient operation and flexibility with its 4-way air deflection. The energy efficiency ratio (EER) is approximately 12, which is good but not the highest available. Unfortunately, it is not Energy Star certified, which might be a consideration if energy savings are a priority for you.

Another handy feature is the 24-hour on/off timer, allowing you to set your cooling schedule and save on energy costs. The included filter light reminder and washable filter simplify maintenance. The provided window installation kit should make setup straightforward. Some users might find the lack of Energy Star certification a drawback in terms of long-term energy savings.

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 GE ClearView 10,000 BTU window air conditioner is a strong contender for those seeking efficient cooling for medium-sized rooms up to 450 square feet. Its standout features include an impressive 10,300 BTU cooling capacity and inverter technology that enhances energy efficiency, achieving a SEER of 11.2. This efficiency is complemented by its Energy Star certification, which promises lower energy bills.

The unit operates ultra quietly at just 40 decibels, making it ideal for those sensitive to noise or for use in bedrooms or living rooms. Installation is straightforward with its full window view design, allowing natural light and functional window use even after the unit is set up—a rare feature in window ACs. The flex-depth design ensures versatile fitting for varying wall thicknesses, supporting a secure and custom fit.

An added bonus is its built-in Wi-Fi capability, allowing remote control via the SmartHQ app or through voice assistants like Alexa and Google Assistant. However, at 75.7 pounds, it might require assistance during installation. While it includes a remote for convenience, the lack of a more advanced SEER rating could be a slight drawback for those seeking the utmost energy efficiency. For someone prioritizing quiet operation and smart features in an air conditioner, this GE model offers a compelling mix of performance and innovation.
