10 Best Non Window Ac Units 2026 in the United States

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 is a solid choice for cooling medium to large rooms up to 700 square feet, thanks to its strong 14,000 BTU cooling capacity (10,200 BTU SACC). It offers good versatility by combining an air conditioner, dehumidifier, and fan in one unit. Its energy efficiency rating (SEER of 6.2) is respectable for a portable AC, helping keep electricity bills reasonable. Noise-wise, it operates at around 54 dB, which is noticeable but generally not too disruptive for most home environments. Portability is decent for its size, weighing about 62 pounds and having manageable dimensions, though it’s not something you'd move frequently without some effort.

Installation is straightforward with the included window kit and exhaust hose, making setup manageable for most users without professional help. The washable filter also simplifies maintenance. A standout feature is the smart connectivity: Wi-Fi control through a mobile app and compatibility with Alexa and Google Assistant adds convenience and modern ease of use. The 'Follow Me' remote, which uses the remote’s location as a thermostat, helps maintain precise comfort where you are.

On the downside, while the unit covers large rooms, it is relatively bulky and heavy for a portable model. The noise level might be a bit loud if you prefer very quiet cooling, especially for bedrooms. Also, the unit uses R-32 refrigerant, which is more eco-friendly but may require professional service if refills are needed. This BLACK+DECKER model is well suited for users who want a powerful, multi-functional portable AC with smart features and easy installation, particularly in room sizes around 700 sq. ft. It may be less ideal if you prioritize ultra-quiet operation or need a very lightweight unit for frequent moves.

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.
