10 Best Non Window Ac Units 2025 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 10,000 BTU Portable Air Conditioner is a versatile choice for rooms up to 450 square feet. It offers a solid cooling capacity suitable for medium-sized rooms, with a 3-in-1 functionality that includes an air conditioner, dehumidifier, and fan. This makes it a flexible option for various climate needs throughout the year.

The unit is portable, featuring casters and side handles that make it easy to move between rooms, and it includes a convenient remote control and a top-mounted LED display for easy operation. Users will appreciate the slide-out washable filter and auto water evaporation feature that simplify maintenance, along with the 24-hour timer for setting cooling schedules. The included installation kit allows for straightforward setup, making it user-friendly even for those who aren't particularly handy.

The noise level is 52 dB, which is relatively quiet but might still be noticeable in very quiet settings such as during sleep. One drawback is its SEER rating of 6.7, which isn't the most energy-efficient on the market. This means it might consume more electricity compared to some other models, potentially leading to higher energy bills. At 47.3 pounds, it is not the lightest unit, but the casters help mitigate this issue. With a 1-year limited warranty, this portable air conditioner is a reliable option for anyone looking to cool a medium-sized room efficiently, albeit with slightly higher energy consumption.

The Dreo Portable Air Conditioner offers 8,000 BTU cooling power, which is suitable for small to medium bedrooms up to about 150 square feet. It uses R-32 refrigerant and provides a decent energy efficiency ratio (SEER) of 6.1, helping to keep electricity use moderate. Noise levels are impressively low at 45 dB, making it quiet enough for bedrooms or home offices without disturbing sleep or work. One standout feature is its patented drainage-free system that evaporates excess moisture automatically, so you won’t have to worry about manually emptying water tanks in most humidity conditions. This adds convenience and reduces maintenance effort.

The unit is portable, equipped with smooth caster wheels, and includes modular window panels and a 59-inch exhaust hose, allowing relatively simple installation on various window types and easy movement between rooms. Its smart climate controls are friendly for everyday use, supporting voice commands through Alexa, Google Home, and Siri, and offering app control for temperature, humidity monitoring, and a custom sleep mode. The 3-in-1 functionality lets you cool, fan, or dehumidify, adding versatility beyond basic cooling.

While 8,000 BTU is fine for smaller spaces, it might struggle in larger rooms or very hot climates. The weight of 55 pounds means it’s portable but not ultra-light, so moving it frequently might require some effort. Its energy efficiency is good but not top-tier compared to some newer models. Installation is easier than most window ACs but still requires setting up the window kit and exhaust hose, which could be a minor hassle for some. This unit represents a solid choice for bedroom or small room use, especially if you value quiet operation, smart features, and low maintenance.
