10 Best Windows Ac Units 2025 in the United States

The Midea 6,000 BTU Window Air Conditioner is a solid choice if you need to cool a room up to about 250 square feet, such as a bedroom, office, or study. Its cooling power is suitable for small to medium spaces, giving quick relief from heat. One standout feature is the 3-in-1 functionality: it cools, circulates air with a 3-speed fan, and even reduces humidity, which adds comfort in damp environments. The unit operates quietly with noise levels around 52 dB on low mode, meaning it won't be disruptive during sleep or work.

Installation is straightforward for anyone with basic DIY skills, fitting standard windows 23 to 36 inches wide, and it comes with all mounting hardware except a screwdriver. The remote control and LED display make it easy to adjust settings from across the room. In terms of energy efficiency, it has a SEER rating of 12.1 but is not Energy Star certified, so it saves some energy but may not be the most efficient model available. Features like Eco mode and a programmable timer help reduce electricity consumption. The included reusable air filter protects against dust and pet hair, which is helpful for cleaner indoor air.

The cooling capacity might be limited if your space is larger than 250 sq. ft., and the noise level, while low, might still be noticeable in very quiet environments. Also, it lacks Energy Star certification, which might be important if you want the highest energy savings. The unit’s weight (38 pounds) is moderate, so some care is needed during installation. Midea backs the product with a one-year warranty, providing some peace of mind. This air conditioner is well suited for users needing a reliable, easy-to-use window unit for smaller rooms, offering multiple comfort modes and decent energy control without complicated setup or excessive noise.

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.
