10 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 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.

The KAMLAM 12000 BTU Portable Air Conditioner is designed for cooling rooms up to 500 square feet, making it suitable for bedrooms, living rooms, and small offices. With its 3-in-1 functionality, it not only cools but also acts as a dehumidifier and fan, providing versatile climate control. The cooling capacity is strong with 12,000 BTUs, ensuring quick cooling, and the dehumidifier can manage up to 76 pints per day, which is beneficial in humid environments.

Its energy efficiency ratio (EER) is not explicitly stated, but the use of an R32 refrigerant suggests a focus on efficiency and environmental care. The unit operates at a relatively quiet noise level of 48-52 dB, promoting a peaceful environment, especially in sleep mode. Portability is enhanced by four caster wheels and hidden handles, despite its 50-pound weight. Installation is straightforward with a provided window kit, suitable for both vertical and horizontal windows, and the easy switch between Fahrenheit and Celsius on the display adds convenience.

Control options include a remote control with a 28-foot range and an LED panel, allowing easy adjustments from a distance. However, users should note that in very humid environments, manual draining may be required, which could be inconvenient. Moreover, while it boasts high energy efficiency, the annual energy consumption is relatively high at 700 kilowatt hours. This unit is best suited for users seeking a comprehensive, portable cooling solution without the need for permanent installation, though its effectiveness in extremely humid settings might need additional consideration.
