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.

This Line Blaster portable air conditioner offers solid cooling power with 8500 BTU, suitable for rooms up to 450 square feet like bedrooms and home offices. It cools quickly, bringing temperatures down to 61°F in about 8 to 15 minutes, which is handy for beating summer heat fast. The 3-in-1 design, combining cooling, dehumidifying, and fan modes, provides year-round comfort without needing extra devices.

Noise levels are quite low at 52 decibels, quieter than a normal conversation, making it a good choice for bedrooms and light sleepers, especially with the Sleep Mode feature that gently adjusts settings overnight. Portability is strong thanks to 360-degree swivel wheels and side handles, letting you easily move it between rooms without hassle. Installation is renter-friendly, with a tool-free window mount kit and exhaust hose that fit most windows, so no permanent changes or professional help are required.

On the downside, energy consumption is on the higher side at 840 watts, so it might impact electricity bills if used extensively. Also, while the unit is compact, it still weighs 43 pounds, which might be a bit heavy for some to move frequently. The included mesh filter will need regular cleaning to keep performance optimal. This unit suits anyone needing a versatile, quiet, and portable AC for small to medium indoor spaces, especially renters or those who prefer an easy setup and multi-function use.

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.
