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

The Whynter NEX Inverter Portable Air Conditioner stands out as a versatile and efficient option for cooling rooms up to 600 square feet. With a substantial 14,000 BTU cooling capacity, it can handle large spaces effectively. One major plus is its dual-hose design, which improves efficiency and minimizes heat leakage compared to single-hose models. Another highlight is the SEER rating of 12.3, indicating good energy efficiency, though it does not have an Energy Star certification. This could be a minor drawback for those specifically looking for Energy Star-rated appliances.

The noise level at 42.5 dB is relatively quiet for a portable unit, making it suitable for bedrooms or living rooms without causing major disturbances. Portability is a key feature, with its compact dimensions and built-in wheels, making it easy to move around. Installation is user-friendly with the included window kit, even though window usage is minimized. The built-in dehumidifier with a capacity of 87 pints per day is a strong feature, addressing high humidity environments effectively.

The unit offers smart control capabilities via the NetHome Plus app and compatibility with Alexa and Google Home, allowing for convenient operation from anywhere. However, the power consumption at 1293W might be on the higher side for some users concerned about electricity usage. In conclusion, the Whynter NEX Inverter Portable Air Conditioner is a well-rounded choice for those needing a powerful, efficient, and smart-controlled cooling solution without the need for traditional window installation.

The LG 7,800 BTU Through the Wall Air Conditioner is a solid choice for those needing an alternative to traditional window units, especially in rooms up to 330 square feet. With a cooling capacity of 7,800 BTU, it can efficiently handle moderate-sized spaces like bedrooms or offices. Its energy efficiency ratio (EER) of 10.7 is respectable, making it cost-effective in terms of power consumption. The unit uses R-32 refrigerant, known for being environmentally friendly and effective. Installation is straightforward for through-the-wall setups, with dimensions that fit standard wall sleeves, but it's not suitable for window installations, which might limit its versatility.

Noise levels are moderate at 56 dB, which is reasonable for most home settings, ensuring that it doesn't disrupt daily activities excessively. Portability isn't a feature here; once installed, it remains in place, but this suits permanent setups well. The unit also doubles as a dehumidifier, which adds to its functionality, especially in humid climates.

This model comes with a remote control, offering convenience in adjusting the three cooling speeds and pre-programmed cooling modes, including an energy saver mode for efficient operation. However, it lacks the Energy Star certification, which may concern those particularly focused on energy savings. Additional accessories like a washable filter and trim kit aid in maintenance and installation. The LG Through the Wall Air Conditioner is a reliable choice for through-the-wall applications, offering good cooling performance, energy efficiency, and ease of operation, though with limited flexibility in installation options.

The Whynter Portable Air Conditioner ARC-14SH is a versatile cooling solution for spaces up to 500 sq. ft. With a cooling capacity of 14,000 BTU, it effectively cools large areas. One of its notable strengths is its quiet operation, producing only 51 dB of noise at low speed, making it ideal for bedrooms and other quiet environments. The unit is also environmentally friendly, using CFC-free R-32 refrigerant.

It offers multiple functionalities with four operational modes: cooling, dehumidifying, fan, and heating, allowing year-round use. The built-in dehumidifier has a robust 71 pints/day capacity and an auto drain function, which is handy for maintaining comfortable humidity levels. However, the Energy Efficiency Ratio (EER) of 7.6 is relatively low, meaning it might not be the most energy-efficient option available. Additionally, the unit is fairly heavy at 85 pounds, which may affect its portability despite being labeled as portable.

Installation requires a window kit, which may not be suitable for all window types or be as straightforward as a plug-and-play device. The product comes with necessary accessories, including an extendable hose, window kit, and storage bag. It also includes a one-year warranty on the unit and a three-year warranty on the compressor. While it may not be the most energy-efficient, its strong cooling performance and versatility make it a solid choice for those needing a reliable portable AC unit.
