10 Best In Wall Ac Units 2025 in the United States

The LG 9,800 BTU through-the-wall air conditioner is a solid choice for cooling medium-sized rooms up to about 440 square feet, such as bedrooms or small offices. Its cooling power is suitable for maintaining a comfortable temperature in that space. A useful bonus is the supplemental heating feature, allowing you to warm the room on cooler days without needing a separate heater. The unit offers two fan speeds for both heating and cooling, giving you some control over airflow to match your comfort preferences. Installation requires a wall opening and a 230V power supply, which is typical for in-wall ACs but might need professional help if you aren't handy. Noise level is around 54 dB, which is moderate—noticeable but not overly loud, so it should be okay for bedrooms.

The Energy Efficiency Ratio (EER) is 9.8, which is average but it does not have Energy Star certification, meaning it might use more electricity compared to more efficient models. The included remote control and easy-to-use digital panel make operation convenient, and features like auto-restart after power outage and a washable filter add to ease of maintenance. Due to the unit’s size and weight (about 70 pounds), installation isn’t a quick DIY job. It also lacks advanced energy-saving features found in newer models. If you want an all-in-one wall unit that cools and heats moderately sized rooms and accept moderate energy performance, this LG model presents a practical option.

The LG 7,800 BTU Through the Wall Air Conditioner is designed for cooling rooms up to 330 square feet, making it a good choice for bedrooms or offices. Its cooling capacity is sufficient for moderate-sized spaces.

This unit operates at 115 volts and requires through-the-wall installation, not suitable for window mounting, so ensure your space can accommodate this setup. Installation aids like a plastic trim kit and foam insulation are included, which can simplify the process somewhat. At 56 dB, the noise level is moderate, which might be noticeable but generally acceptable for residential use.

Its remote control and multiple cooling speeds add convenience and customization to its use. Additional features like a filter light reminder and dehumidifier function enhance its value. However, the absence of an Energy Star rating might be a drawback for those prioritizing top-tier energy savings. Additionally, while the remote control is convenient, the unit does not include batteries, requiring an extra purchase.
