10 Best 115 Volt Air Conditioners 2026 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 Frigidaire 12,000 BTU Window Air Conditioner is a solid choice for cooling rooms up to 550 square feet, making it suitable for medium to larger living spaces or offices. With a cooling power of 12,000 BTUs, it effectively lowers room temperature, and its 115-volt design fits standard home electrical setups. The unit operates quietly at about 57 decibels, which is fairly low for an air conditioner of this size, allowing you to run it without much distraction in bedrooms or living areas. Its Seasonal Energy Efficiency Ratio (SEER) is 10.9, which is moderate—while it’s not the most energy-saving model available, features like Eco Mode and Sleep Mode help reduce electricity use during operation.

Installation is straightforward as it fits into standard windows and comes with a window kit for convenience. The included remote control and 24-hour timer add to ease of use, letting you adjust settings without getting up. Additional perks include a washable dust filter with a clean filter alert, 6-way directional airflow for even cooling, and a Dry Mode to reduce humidity, improving comfort in moist climates. On the downside, this model isn’t Energy Star certified, so if energy efficiency is your top priority, there might be better options. Also, while 57 dB is quiet, some ultra-quiet models operate at lower noise levels. The unit weighs about 63.5 pounds, so installation might require some help.

This air conditioner balances effective cooling, decent energy features, and user-friendly controls, making it a good pick if you want reliable window cooling without too much fuss.

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.
