10 Best Windows Ac Units 2026 in the United States

The Amazon Basics 6000-BTU Window Air Conditioner is a solid choice for cooling rooms up to 250 square feet, such as bedrooms or home offices. Its 6000 BTU cooling capacity is well-suited for small to medium spaces, and the unit offers both cooling and fan-only modes, giving you flexibility depending on the weather. With 7 temperature settings and 2 fan speeds, you can customize comfort easily. It operates quietly at around 56 decibels, which means it won’t disturb sleep or work.

Energy efficiency is decent with a SEER rating of 12.1, helping keep electricity bills reasonable but not top of the line. Installation is straightforward for most standard windows between 23 and 36 inches wide, and the adjustable window kit with expandable panels is a helpful feature. Basic tools like a screwdriver are needed but not included. Maintenance is simple thanks to the washable filter that traps dust and allergens, beneficial for keeping the air cleaner without ongoing replacement costs. The unit includes a remote control and digital temperature display, adding convenience.

On the downside, at nearly 42 pounds, it’s somewhat heavy for a single person to install alone. Although the noise level is low compared to many AC units, 56 dB might still be noticeable in very quiet rooms. The cooling power is ideal only up to 250 sq ft, so larger rooms will need a stronger unit. The energy efficiency is good but not exceptional, so there are more energy-saving options available. This unit provides a user-friendly, affordable, and efficient solution for small spaces needing reliable cooling without much fuss, fitting well for those wanting easy installation, quiet operation, and basic smart features like a remote and filter maintenance.

The LG 12,000 BTU Smart Window Air Conditioner is designed to cool rooms up to 550 square feet, making it a solid choice for larger kitchens or living rooms. Its cooling capacity is suitable for medium to large spaces, providing three fan speeds plus an auto cool mode to help customize airflow. The unit operates quietly at about 52 decibels on its low setting, so it won’t be too distracting in your home environment.

While its energy efficiency ratio (EER) is 12, which is decent, it is not Energy Star certified, so it may not be the most energy-saving option available. The physical size is fairly standard for a window AC of this power, and it comes with everything needed for installation like an installation kit and mesh filter. A standout feature is the smart connectivity through LG ThinQ, allowing you to control the unit via your phone or voice assistants like Alexa and Google Assistant, which adds convenience for users who want modern control options.

Additional perks include a 24-hour timer, filter reminder, dehumidifier function, and auto restart after power outages. However, the unit weighs 81 pounds, which could make installation a bit challenging without help. The 1-year parts and labor warranty provides reasonable support. This LG window AC is a good pick if you value smart features, quiet operation, and effective cooling for larger rooms but want to keep in mind it doesn’t have the highest energy efficiency rating.

The Amazon Basics Window Air Conditioner is a compact unit with a cooling capacity of 5000 BTUs, making it suitable for small rooms up to 150 square feet. This means it is ideal for bedrooms, small living rooms, or office spaces. One of its strengths is its 3-in-1 functionality, offering cooling, dehumidifying, and fan options, which can enhance comfort in different conditions.

With seven temperature settings and dual cooling and fan settings, users have good control over their environment. The adjustable air direction is a plus, allowing you to direct the cool air where you need it most. The unit is designed to fit standard windows with its adjustable side panels, simplifying installation for many users. Additionally, the built-in filter is removable, washable, and reusable, making maintenance straightforward and cost-effective.

The air conditioner uses mechanical controls, which may feel less modern compared to digital interfaces. Weighing about 35 pounds, it might be slightly heavy for some users to install on their own. Despite these minor drawbacks, its ease of maintenance, versatility in fitting different window sizes, and multiple functionality make it a solid option for those looking to cool a small space without spending a lot.
