10 Best Lightweight Window Air Conditioner 2025 in the United States

The Midea 5,000 BTU EasyCool Small Window Air Conditioner is a great option for cooling small rooms up to 150 square feet. It offers a decent cooling capacity with 5,000 BTUs, making it suitable for small bedrooms, living rooms, or home offices. One of its standout features is its energy efficiency, with a Combined Energy Efficiency Rate (CEER) of 11.0, which helps in reducing energy costs. However, it is not Energy Star certified, which might be a consideration for some buyers looking for the most energy-efficient options available.

The noise level is 57 dB, which is relatively quiet, comparable to a household refrigerator, making it suitable for a peaceful environment. Weighing 35.3 pounds and with dimensions of 15.35"D x 15.98"W x 12.05"H, it is compact and lightweight, making installation relatively easy. The unit features mechanical controls that are straightforward to use, and it includes a removable and reusable filter for easy maintenance.

Additional features include 7 temperature settings, 2 cooling and 2 fan-only speeds, and 2-way air direction, allowing for customizable comfort. The installation process is user-friendly, with all necessary mounting accessories included, although a screwdriver is required. A one-year parts and labor warranty provides some peace of mind regarding the product's quality. The Midea 5,000 BTU EasyCool is a solid, budget-friendly choice for those needing an efficient solution for smaller spaces.

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. Its cooling power fits spaces roughly 14 by 25 feet, covering many common room sizes effectively. Notably, it operates quietly, running as low as 53 decibels on the lowest fan setting, so it won’t disturb sleep or work. It offers three fan speeds and an Auto Cool mode, allowing easy airflow adjustment for comfort. The unit includes convenient features like a remote control, a digital panel for simple operation, and a 4-way air deflection to direct cool air where desired. Maintenance is straightforward with a slide-out, washable filter and a filter light reminder. 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. This LG model is suitable for those seeking a reliable, quiet air conditioner that cools efficiently without too many complicated features, making it ideal for bedrooms or smaller apartments where noise level and ease of use are priorities.

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.
