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 Frigidaire FHWC054TE1 Window Air Conditioner offers a cooling capacity of 5000 BTUs, making it suitable for small spaces up to 150 square feet. One of its key strengths is the multi-speed fan, which provides three different fan speeds for flexible cooling options. This unit also includes a remote control, a filter light reminder, and a washable dust filter, adding to its convenience and ease of use.

With a noise level of 52 dB, it operates relatively quietly, which can be a significant advantage for light sleepers or those who prefer a quieter environment. The air conditioner has an Energy Efficiency Ratio (EER) of 11, which is decent but not the highest in its category. It's also important to note that it is not Energy Star rated, which might affect long-term energy savings.

Weighing 35.5 pounds and with dimensions of 14.4 x 16 x 12.2 inches, it's relatively lightweight and compact, making installation easier. The unit also comes with a window kit and two AAA batteries for the remote, making it ready to use out of the box. Some potential drawbacks include its lack of an Energy Star rating and the absence of advanced features such as smart home compatibility. This air conditioner is suitable for those looking for a straightforward, reliable cooling solution for small rooms at a reasonable price.

The LG LW1024RD window air conditioner is a solid choice for cooling medium-sized rooms up to 450 square feet, making it suitable for larger bedrooms or living rooms. It delivers a decent cooling capacity of 10,000 BTUs, which is enough to keep such spaces comfortable during warm weather. The unit offers three fan speeds and an Auto Cool mode, allowing you to fine-tune the airflow and cooling to your preference. One noteworthy feature is the quiet operation on low mode, running at about 52 dB, so it won’t distract you with loud noise—although on higher settings, noise can reach around 60 dB, which is average for window units. The energy efficiency ratio (EER) is 11.4, which is reasonable but not the highest in its class, so you might see moderate electricity use compared to more energy-star rated models.

It includes convenient features like electronic controls with a remote and an auto-restart function that turns the AC back on after a power outage, adding to ease of use. Physically, it weighs 57 pounds and has typical window AC dimensions, which means installation may require two people and checking your window size to ensure a good fit. The unit also has a built-in dehumidifier, which can improve indoor comfort by reducing moisture. A potential downside is the one-year limited warranty, which is standard but on the shorter side for major appliances. This LG air conditioner is a reliable, user-friendly option if you want effective cooling with quiet operation and handy features for medium-sized rooms, but keep in mind it’s not the lightest or most energy-efficient model available.
