10 Best Thru Wall Ac Units 2025 in the United States

The LG 11,800 BTU through-the-wall air conditioner is well suited for cooling medium-sized rooms up to around 530 square feet, making it a good fit for bedrooms, living rooms, or apartments. Its cooling power is strong enough to keep these spaces comfortable on warm days. The unit uses an energy-efficient R-32 refrigerant with an Energy Efficiency Ratio (EER) of 10.6, which helps reduce electricity costs compared to less efficient models, although it doesn’t have the Energy Star certification to guarantee top-level efficiency.

Noise level is at 66 decibels, which is a bit louder than some quieter models, so it might be noticeable in very quiet settings like bedrooms at night. Installation requires a through-the-wall sleeve, and the unit won’t work in standard window frames. It comes with a universal design to fit most wall sleeves and includes helpful accessories like a trim kit, filter, insulation foam, and a remote control, making the setup somewhat easier. The unit offers three cooling and fan speeds plus multiple modes, including Energy Saver and Dry modes, which help manage humidity and save power by cycling the compressor off when the set temperature is reached.

The product weighs 76 pounds, so installation might require professional help. The 1-year limited warranty provides some peace of mind but is fairly standard. This LG air conditioner is a solid choice if you need reliable cooling through a wall installation for medium spaces and want some energy savings, but it may be a bit noisy and installation could be challenging without assistance.

The LG 9,800 BTU Through the Wall Air Conditioner is a solid choice for cooling medium-sized rooms, making it ideal for bedrooms or offices up to 440 square feet. Its dual function as both an air conditioner and heater allows users to enjoy comfort year-round, which is a significant advantage. The multiple fan speeds and 4-way air deflection provide personalized airflow, helping to achieve the desired temperature quickly and efficiently.

The energy efficiency ratio (EER) of 9.8 is decent, though it's worth noting that this unit is not Energy Star rated, which may be a consideration for those looking to reduce energy costs. The noise level at 54 dB is fairly typical for through-wall units, which means it may not be completely silent but should be manageable in a bedroom or office setting.

Installation may require some effort, as it needs to be fitted through a wall, but the included trim kit can simplify this process. The added convenience of a remote control and a digital control panel enhances usability, allowing you to make adjustments without getting up. Additionally, the auto-restart feature is a practical touch, providing peace of mind after power outages. However, potential buyers should be aware of the unit’s weight at 70 pounds, which might require assistance for installation. The warranty is limited to one year, which is on the shorter side compared to some competitors.
