10 Best Lightweight Window Air Conditioner 2025 in the United States

The GE 5000 BTU window air conditioner is a solid choice for small rooms up to 150 square feet like bedrooms or home offices. Its cooling power is suitable for compact spaces, providing enough refreshment without being overpowering. One strong point is its relatively low noise level at 56 dB, making it quiet enough for nighttime use without disturbing your sleep. The unit is lightweight at just under 5 pounds and has a compact size, which makes it easier to install and less bulky than heavier models. Installation is user-friendly thanks to the included EZ Mount kit designed for double-hung windows, so you likely won't need professional help.

The air conditioner offers adjustable controls with two fan speeds, two cooling modes, and 10 temperature settings, allowing flexible comfort management. The washable filter is a nice feature for easy maintenance and longer-lasting performance. On the energy side, the unit has a Seasonal Energy Efficiency Ratio (SEER) of 11, which is decent but not top-tier, so it won’t be the most energy-saving option available. It is well-rated by users and backed by a 1-year warranty, making it a reliable choice for small spaces.

If you want a straightforward, compact air conditioner that cools small spaces effectively without complicated features, this GE unit fits the bill nicely. However, it might not be ideal for rooms larger than 150 square feet or for those seeking ultra-quiet operation below 50 dB.

The LG 8,000 BTU Window Air Conditioner is a solid choice for cooling medium-sized rooms up to about 350 square feet, such as bedrooms or small living rooms.

The Auto Restart feature ensures it turns back on after a power outage, which is beneficial in areas with unstable electricity.

However, the unit weighs 58 pounds, which might require two people for safe installation. It is not Energy Star rated and has a Seasonal Energy Efficiency Ratio (SEER) of 13, indicating it is less energy-efficient compared to some other models and may incur higher electricity costs with frequent use. The dimensions are compact but typical for this cooling capacity. A 1-year warranty covering parts and labor is included.
