10 Best LG Window Ac Units 2025 in the United States

The LG LW1224RD window air conditioner is a solid choice for cooling rooms up to 550 square feet, making it suitable for larger spaces like living rooms or master bedrooms. With a cooling capacity of 12,000 BTU, it provides strong cooling power for most medium to large rooms. Its Seasonal Energy Efficiency Ratio (SEER) of 11.4 suggests it offers decent energy savings, though it’s not the top in efficiency compared to some newer models. Noise-wise, it operates quietly at 53 dB on low settings, which helps keep your environment peaceful without the usual hum of an AC unit.

Installation is straightforward for standard windows, and LG includes window curtain panels to help with fit and insulation. The electronic controls paired with a remote make it convenient to adjust settings without getting up, and the three fan speeds plus an Auto Cool mode allow you to customize airflow to your comfort. Additional handy features include an auto restart after power outages—so you don’t have to reset it manually—and a built-in dehumidifier that helps reduce moisture in the air. On the downside, the unit weighs 82 pounds, which might make installation tricky without help.

While it lacks a formal energy star rating, its efficiency is reasonable but not the very best available. Some users might find that the noise is still noticeable at higher fan speeds. The one-year warranty is standard but not extensive. This LG model is a dependable, moderately efficient window AC that balances quiet operation and user-friendly features, making it ideal for someone needing reliable cooling in a sizable room without complicated setup or controls.

The LG 18,000 BTU Window Air Conditioner with Heat is a solid choice if you need both cooling and supplemental heating in medium-sized rooms up to about 1,000 square feet, such as bedrooms, living rooms, or basements. Its cooling capacity is strong enough for spaces roughly 25 by 40 feet, providing effective climate control. The unit offers two fan speeds for cooling, heating, and just air circulation, so you can adjust airflow to your comfort. Installation requires a special 230/208V plug, which might mean extra setup considerations compared to standard 115V window ACs.

Noise-wise, it runs at about 61.7 decibels, which is moderately loud and could be noticeable in quiet rooms. The energy efficiency ratio (EER) is relatively low at 2.8, indicating it may use more electricity than some newer, high-efficiency models. On the plus side, the digital control panel and remote control make operation easy, and features like a 24-hour timer, auto-restart after power outages, and washable filters add convenience and usability. The 4-way air deflection helps distribute cooled or heated air more evenly.

The unit’s weight is on the heavier side, so installation may require help. Although it doesn’t have a high energy star rating, it’s a versatile unit for year-round use in spaces needing both cooling and heating without separate devices. If you want something simple, reliable, and multifunctional and don’t mind moderate noise or energy use, this LG model fits well.

The LG 7,600 BTU Window Air Conditioner with Heat is designed to cool and heat medium-sized rooms up to about 330 square feet, making it suitable for bedrooms, small living rooms, or apartments. Its cooling capacity of 7,500 BTU is adequate for this size, and it operates quietly at around 50 decibels on low, which won’t disturb your sleep or work. The unit offers two fan and temperature settings, giving you some control over airflow and comfort. Energy efficiency is reasonable with a Seasonal Energy Efficiency Ratio (SEER) of 11.3, but it lacks a formal Energy Star rating, so it may not be the most efficient option available. Installation is fairly straightforward with a slide in-out chassis and included kit, although a compatible window size and some basic setup are necessary. The built-in heating feature is a valuable bonus for cooler days, helping maintain a steady temperature year-round.

Additional conveniences include a remote control, 24-hour timer, auto-restart after power outages, and filter reminders, which enhance ease of use and maintenance. On the downside, the unit weighs 69 pounds, which might make installation a bit challenging for some users, and the warranty is limited to one year. This LG model delivers reliable performance and useful extras for those needing both cooling and heating in a medium room, though energy-conscious buyers may want to consider higher efficiency models.
