10 Best Non Window Ac Units 2026 in the United States

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.

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 TOSOT GO Cool RV Air Conditioner offers strong cooling and heating with a 15,000 BTU cooling capacity and a 12,000 BTU heat pump, making it suitable for RVs sized between 16 and 24 feet or spaces up to 600 square feet. Its energy efficiency ratio (EER) of 8.5 is fairly good for an RV unit, helping keep power use reasonable during trips. Noise level is moderate at 52 dB, so it won’t be completely silent but should be acceptable for most users inside an RV.

Installation is straightforward for compatible RVs since this is a ductless, rooftop-mounted system designed to fit standard vent openings, but it won’t work for RVs with ductwork. The included sealing kit aids in quick setup. Portability is limited since it’s a fixed rooftop unit, but this is typical for RV ACs. One standout feature is smart WiFi control and remote operation via an app, which adds convenience by letting you adjust temperature settings without getting up. It also performs well across a wide range of outdoor temperatures, from freezing cold (23°F) to very hot (115°F), making it versatile for different climates.

On the downside, it’s relatively large and heavy, and it does not have an Energy Star rating, so energy savings could be better. Some users may find the shipping in multiple packages inconvenient. This AC unit represents a solid choice for RV owners seeking a reliable, dual-function cooling and heating system with smart controls, provided their RV roof vent matches the standard size and they don’t require a ducted system.
