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 SereneLife Portable Air Conditioner delivers strong cooling power with 14,000 BTU, making it suitable for rooms up to around 650-700 square feet, which fits well if you want to cool medium-sized spaces like bedrooms or offices. It supports three functions—air conditioning, dehumidifying, and fan mode—with three speed settings, giving you flexible options depending on your needs. Its energy efficiency is moderate, with a 3-star rating and a Seasonal Energy Efficiency Ratio (SEER) of 14, which is decent for portable units but not the most efficient on the market, so expect average electricity use.

Portability is a highlight: although it weighs about 68 pounds and has a compact design, it comes with a remote control and a window mount exhaust kit making setup relatively straightforward for temporary use. The included washable filter helps keep maintenance simple. Noise-wise, it operates at about 57 dBA, roughly the sound level of a normal conversation, which might be noticeable but generally not disruptive. Installation requires placing the exhaust hose in a window using the provided kit, which is common but might need some effort depending on your window size and type.

On the downside, this model lacks inverter technology, which means it may consume more power and run less quietly compared to inverter ACs. The build is sturdy but somewhat bulky for moving frequently. Taking these factors into account, the SereneLife portable AC is a solid choice for those needing a flexible cooling solution without permanent installation, especially if you value multiple modes and relatively simple maintenance. However, it may not be the quietest or most energy-saving option for very frequent or long-term use.

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.
