10 Best Floor AC Units 2026 in the United States

The LG 12,000 BTU Smart Window Air Conditioner is a solid choice for cooling rooms up to 550 square feet, such as kitchens or living rooms. With its strong cooling power, it can quickly bring down the temperature in medium to large spaces. It features three fan speeds and an Auto Cool mode, giving you flexibility to adjust airflow and comfort. Noise is kept relatively low at 52 dB on the lowest setting, which means it won’t be too disruptive during use. The unit also includes a dehumidifier with a 3.8-pint moisture capacity, helping to reduce humidity alongside cooling, which is handy in warmer, muggy environments.

Its energy efficiency rating (SEER 12) is decent, though it may not be the most energy-saving model available. One of the standout features is the smart control via LG ThinQ app and voice assistants like Alexa and Google Assistant, allowing you to adjust settings remotely or hands-free, adding convenience especially if you’re busy or away from home. The included remote control and timer further enhance ease of use.

This is a window unit, so portability is limited compared to portable ACs; installation requires a suitable window and some effort. It operates on standard 115V power, making it compatible with typical home outlets but not suited for larger power setups. The 1-year warranty is fairly standard and might feel short if you want longer coverage. Taking these points into account, this LG model suits users looking for a reliable, moderately efficient window AC with smart controls and decent noise levels for medium-sized rooms.

The LG 23,000 BTU Window Air Conditioner with Heat is powerful enough to cool or heat rooms up to about 1400 square feet, making it a solid choice for larger living spaces like a living room, bedroom, or office. It offers a good energy efficiency ratio (SEER 11.3), which means it balances performance with reasonable power consumption. Noise-wise, it operates quietly at around 50-51 decibels on low settings, so it won't be too disruptive whether you're working or sleeping. This unit includes a dehumidifier that can remove about 3.3 pints of moisture from the air, helping to keep your space comfortable and less humid.

For controls, it comes with a remote, allowing easy adjustment from across the room, and has multiple fan speeds for customizing airflow. The auto restart feature is handy if you experience power outages, as it resumes operation without needing manual intervention. On the downside, the unit is quite heavy at 145 pounds and fairly large in size, so while it’s a window unit, it’s not very portable and may require two people to install. Also, it does not have a high star energy rating, so while energy efficiency is decent, it’s not the top performer in this regard.

The included one-year warranty covers parts and labor, which is standard but something to consider for long-term use. This LG unit is well suited for those needing a reliable, no-fuss solution for large rooms that require both heating and cooling year-round.

The LG 9,800 BTU Through the Wall Air Conditioner is designed to cool medium-sized rooms up to about 450 square feet, making it a good fit for bedrooms or offices. It also includes a supplemental heating feature, so it can keep your space warm during cooler days, adding versatility beyond just cooling. The unit offers two fan speeds for both heating and cooling, giving you basic control over airflow and comfort. It comes with a remote control and a digital panel, making it easy to adjust settings from across the room.

With a noise level of 54 decibels, it’s relatively quiet, though some might notice it in very quiet environments. The air conditioner also helps reduce humidity with a 3.2-pint capacity, which can make your room feel more comfortable during humid weather. Energy-wise, the SEER rating of 9.8 is decent but not the highest, so it might not be the most energy-efficient option available. Since it’s a through-the-wall model, it’s less portable than window units and requires professional installation, which is important to consider if you want flexibility or plan to move it around.

The washable filter and filter light reminder are convenient for maintaining good air quality without much hassle. This LG unit is suitable for those looking for a reliable combination of heating and cooling in a medium-sized room, especially if a built-in setup rather than a window or portable AC is preferred.
