10 Best Low Profile Window Air Conditioner 2026 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 suitable for bedrooms, living rooms, and apartments. It operates at a relatively quiet noise level of 52 dB, which is beneficial for maintaining a peaceful environment, especially during sleep or work. The unit offers three cooling and fan speeds, along with an Auto Cool feature, giving you the flexibility to customize the cooling according to your preference.

The digital control panel and remote control enhance its usability by allowing you to adjust settings conveniently from a distance. Additionally, the 4-way air deflection ensures even cooling throughout the room, and the included timer lets you set a cooling schedule to save on energy costs. However, the unit's Seasonal Energy Efficiency Ratio (SEER) of 13 is decent but not the best, and it is not Energy Star certified, which might be a consideration for those looking for the most energy-efficient options.

The dimensions and weight of the unit are fairly standard, but it’s worth noting the product’s size to ensure it fits your window. Installation is made easier with the provided window installation kit, and maintenance is simplified with a slide-out, washable filter and filter light reminder. In summary, the LG 12,000 BTU Window Air Conditioner is a reliable and user-friendly option with some energy efficiency limitations, ideal for medium-sized spaces where quiet operation is valued.

The LG 7,500 BTU Window Air Conditioner is a solid choice for cooling medium-sized rooms up to around 320 square feet, such as bedrooms or small offices. It offers a decent cooling capacity that should keep your space comfortable during warmer days. The unit runs quietly at about 50 decibels on low, so it won’t disturb your peace while it’s working. It also features supplemental heating, which means you can use it year-round to add warmth on cooler days, making it more versatile than models that only cool.

You can adjust the airflow and temperature with two fan and cooling/heating speeds, plus it has convenient electronic controls and a remote, which makes operation easy. Installation is straightforward thanks to its slide in-out chassis and included installation kit, though at nearly 70 pounds it can be a bit heavy to handle alone. The energy efficiency is decent with a SEER rating of 13, which means it won’t be too costly on your electric bill, but it’s not the most efficient model out there.

Its size is fairly compact for a window AC, but you’ll want to check your window dimensions carefully, as it measures about 21 inches wide and 18 inches deep. One minor drawback is the one-year warranty, which is standard but somewhat limited. If you want a reliable, quiet air conditioner with heating capabilities for a moderate-sized room, this LG model covers the basics well without being overly complicated.

The LG 8,000 BTU window air conditioner is designed to cool medium-sized rooms up to about 350 square feet, making it a solid choice for bedrooms, small apartments, or living rooms. It operates quietly, producing noise as low as 53 decibels on its lowest setting, so it won’t disturb your sleep or conversations. The unit offers three different fan and cooling speeds, allowing you to customize airflow and temperature easily. You can control it either through the digital panel or the included remote, adding convenience. Its low-profile size (just under 20 inches in each direction) and the included installation kit make it relatively straightforward to set up on most standard windows. The washable filter and filter reminder help keep maintenance simple.

The energy efficiency ratio (SEER) is 13 and it does not have an Energy Star certification, which means it may use more electricity compared to more efficient models. Weighing about 58 pounds, it’s moderately heavy, so installation might require some help. One handy feature is Auto Restart, which turns the unit back on automatically after a power outage.

This model is well-suited for general home use and offers quiet, reliable cooling. It provides a good balance between ease of use, noise level, and cooling power for typical bedroom or apartment needs, although those focused on maximum energy savings might want to consider other options.
