10 Best Non Window Ac Units 2026 in the United States

The Hisense 8,000 BTU portable air conditioner is a solid choice for cooling spaces up to about 350 square feet, such as bedrooms or small living rooms. It uses dual-hose technology, which cools more efficiently and maintains consistent room temperatures better than single-hose models. Thanks to its inverter compressor, it’s up to 40% more energy-efficient compared to traditional portable ACs, helping to lower electricity bills. The noise level is reasonably quiet at 42 decibels, allowing you to run it overnight without much disturbance.

The unit offers 3-in-1 operation modes: cooling, dehumidifying, and fan, making it versatile for different needs. Installation is straightforward with the included window kit, and it doesn’t require draining water during cooling, which reduces maintenance hassle. It also supports smart control via Wi-Fi with Google and Alexa compatibility, which is convenient if you like managing devices from your phone or with voice commands.

On the downside, it weighs 65 pounds, so it’s somewhat heavy to move around frequently, and it requires a nearby window for venting, which might limit placement options. It doesn't have a BEE star rating, so its efficiency compared to other models might vary depending on usage. The limited 90-day warranty is shorter than some competitors, which is worth considering. This Hisense unit is well suited for users looking for an energy-efficient, relatively quiet, and versatile portable AC with smart features, especially for moderately sized rooms, but those needing lighter or longer-warranty units might want to explore other options.

The BLACK+DECKER 14,000 BTU Portable Air Conditioner and Heater is a versatile unit designed for spaces up to 700 sq. ft. Its 4-in-1 functionality (air conditioner, heater, dehumidifier, and fan) makes it a useful appliance throughout the year. The cooling capacity (14,000 BTU ASHRAE) and heating power (11,000 BTU) are adequate for medium to large rooms, making it a good choice for users needing a multi-functional unit without permanent installation.

The Energy Efficiency Ratio (EER) of 6.2 is on the lower side, meaning it may not be the most energy-efficient option available. However, it offers decent energy usage for its price range. At a noise level of 54 dB, it operates relatively quietly, which is beneficial for settings like bedrooms or home offices. The unit's portability is a significant advantage, featuring casters and side handles for easy movement between rooms. Installation and maintenance are straightforward, thanks to the included window kit and washable filter.

Additional features like the remote control, LED display, auto water evaporation, and a 24-hour timer enhance user convenience. One drawback is its relatively high weight (60.1 lbs), which could pose a challenge for some users when moving the unit. Moreover, it is not Energy Star rated, which might be a concern for those prioritizing energy efficiency. This BLACK+DECKER model is a solid choice for those seeking a portable, multi-functional air conditioner and heater with user-friendly features, although it may not be the most energy-efficient option on the market.

The BLACK+DECKER Smart Portable Air Conditioner offers a strong cooling capacity of 12,000 BTU (8,350 BTU SACC), making it suitable for medium-sized rooms up to 550 sq. ft., such as bedrooms or living areas. It stands out with its three-in-one functionality, combining air conditioning, dehumidifying, and fan modes, which adds flexibility depending on your comfort needs. Its energy efficiency is decent with an EER of 5.8, which can help manage electricity costs compared to less efficient models. Noise level is moderate at 52 decibels—noticeable but not overly loud, so it should be fine for most households, including bedrooms.

The unit’s portability is good, thanks to its compact size and included window installation kit, but it weighs almost 59 pounds, which might make moving it around a bit challenging for some users. Installation is straightforward with the window kit and exhaust hose provided, so you won't need professional help. A key highlight is its smart feature set: Wi-Fi connectivity and voice control via Alexa or Google Assistant allow you to control the unit remotely, and the 'Follow Me' remote acts as a mobile thermostat for better temperature accuracy.

On the downside, the unit doesn’t have an inverter compressor, which means it may consume more power and be less quiet compared to inverter models. Also, it lacks a heating function, so it’s only useful during warmer months. Maintenance is manageable with a washable filter, but the water drain hose requires occasional attention to avoid spills. This BLACK+DECKER portable AC is a solid choice if you want a versatile, smart-controlled unit for medium rooms with decent efficiency and moderate noise, but if lightweight portability or year-round use is a priority, you might want to consider other options.
