7 Best Ac Unit That Doesnt Need A Window 2025 in the United States

The BLACK+DECKER 8,000 BTU Portable Air Conditioner is designed to cool rooms up to 350 square feet, making it a suitable choice for bedrooms or small living areas. It has a 3-in-1 functionality, serving as an air conditioner, dehumidifier, and fan. The unit’s portability is one of its standout features; it comes with casters and side handles, allowing you to move it around effortlessly.

The included installation kit makes setting it up straightforward, although it does require a window for the exhaust hose, which might be a consideration for some buyers. The cooling capacity of 8,000 BTU is adequate for its intended space, but the Energy Efficiency Ratio (EER) of 5.4 is relatively low, meaning it might not be the most energy-efficient option available. At a noise level of 54 dB, it operates relatively quietly, suitable for a bedroom setting, but could still be noticeable for some users.

Control options are convenient with a remote and a 24-hour timer, adding to the ease of use. The dehumidification feature is a plus, especially in humid climates. However, its weight of nearly 53 pounds might be a drawback for some, despite its portable design. This BLACK+DECKER portable AC is a solid choice for those needing a flexible and easy-to-install cooling solution, particularly in spaces where window units are not feasible.

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.
