9 Best Ac Unit That Doesnt Need A Window 2026 in the United States

The BLACK+DECKER Portable Air Conditioner (14,000 BTU cooling) is a solid choice for those seeking a portable cooling solution without the need for a traditional window AC unit. It can cool rooms up to 700 square feet, suitable for bedrooms or living rooms. Its 14,000 BTU cooling capacity is quite powerful, and it also offers heating (10,000 BTU), which adds year-round usability. This unit includes a dehumidifier and fan mode, making it versatile beyond just cooling.

While it’s not Energy Star rated, it has a moderate energy efficiency ratio (EER around 6.2), meaning it won't be the cheapest on your electricity bill but remains reasonable for its power. Noise level is about 52 decibels, roughly the sound of a normal conversation, which some might find noticeable but not disruptive. Portability-wise, it weighs 35 pounds and measures about 27” wide, so it’s portable but a bit bulky to move frequently. Installation is straightforward with the included kit designed for window venting, although this product requires a window for venting the hot air out—so it isn’t fully windowless but avoids permanent window unit installation.

Control options are strong: you get a full remote control with a handy “Follow Me” feature that uses the remote as a thermostat for better temperature accuracy. It also supports Wi-Fi and voice commands through Alexa and Google Assistant, which is convenient if you like smart home features. This BLACK+DECKER model is well suited for users who need both cooling and heating in medium-sized rooms and do not mind the noise level or moderate energy use. Its size and venting requirements make it less ideal for those seeking a lightweight, fully window-free unit for frequent room-to-room movement.

The LG 10,000 BTU Through the Wall Air Conditioner is designed to cool medium-sized rooms up to 440 square feet, making it a solid choice for bedrooms, living rooms, or apartments where window installation isn’t an option. It uses an efficient R-32 refrigerant and has an Energy Efficiency Ratio (EER) of 10.7, which means it balances good cooling ability with reasonable energy use. The unit offers three fan speeds and cooling modes, including an Energy Saver mode that helps reduce power consumption by cycling the compressor based on room temperature. It also has a dry mode that removes moisture effectively, which is a helpful feature in humid climates.

Installation requires a through-the-wall sleeve, so it’s not portable like window units but is easier to install compared to central air. The included trim kit and washable filter add convenience and help keep maintenance simple. Noise-wise, it runs at about 56 decibels, which is noticeable but generally acceptable for indoor use. The remote control adds user-friendly convenience, allowing easy adjustments from across the room.

This model is fairly heavy at 77 pounds, so installation might require professional help. It does not have inverter technology, so it may use more power than some newer models during continuous operation. Also, since it’s not made for window mounting, it’s limited to homes where through-the-wall installation is possible. This LG unit is well suited for those needing a reliable, energy-conscious wall-mounted AC with flexibility in controls and good dehumidification but is less ideal for renters seeking easy installation or very quiet operation.

The LG 11,800 BTU Through the Wall Air Conditioner is designed for those who want cooling without using a traditional window unit. Instead, it installs through a wall, which can be great for apartments or rooms without suitable windows. It cools spaces up to about 530 square feet, which is ideal for bedrooms or living rooms. The unit uses a modern and energy-efficient refrigerant (R-32) with an Energy Efficiency Ratio (EER) of 10.6, meaning it can help keep electricity bills reasonable compared to some older models.

With three different cooling and fan speeds, plus pre-set modes like Energy Saver and Dry (for dehumidifying), it offers versatile climate control. The included remote control makes adjusting settings convenient. Installation requires a wall cutout of specific dimensions, and the product comes with a trim kit and grille to complete the setup neatly.

The noise level is around 60 decibels, which is moderately loud—comparable to a normal conversation—so it might be noticeable in quiet environments. Also, at 76 pounds, it’s not very portable, and installing it requires a permanent wall opening, making it less flexible than window units. It does not have an inverter compressor, which means it won’t adjust power usage as smoothly as some newer models, potentially affecting energy savings. This LG unit is a solid choice if you need a through-the-wall air conditioner with decent cooling power and energy efficiency, especially when window installation isn't possible. However, be prepared for a moderate noise level and a fixed installation that isn’t easily moved.
