10 Best 115 Volt Air Conditioners 2026 in the United States

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.

The Whirlpool 15,000 BTU window air conditioner is designed to cool medium to large rooms, claiming to handle spaces up to 700 square feet. However, the specs show a cooling capacity of only 5,000 BTU and coverage around 150 square feet, which suggests it is better suited for smaller rooms rather than large living areas. This discrepancy is important to keep in mind when choosing this unit.

It operates on 115 volts and offers an Energy Efficiency Ratio of 11, which reflects decent energy use for a window AC. Noise level is moderate at 51 decibels, which is about as loud as a normal conversation, so it’s relatively quiet for home use. Installation is straightforward with the included mounting kit, fitting windows with a minimum height of 19 inches, making it a convenient choice for most standard windows.

Additional features add value, such as a built-in dehumidifier that removes 3.5 pints of moisture per hour, electronic controls with multiple cooling speeds, eco and sleep modes, a 24-hour programmable timer, remote control, and an auto-restart function after power outages. Maintenance is user-friendly thanks to a replaceable filter and a filter clean alert. This Whirlpool AC is well suited for those needing reliable, quieter cooling with added convenience features in smaller rooms rather than large spaces.

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.
