10 Best Non Window Ac Units 2026 in the United States

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.

The Whynter NEX Inverter Portable Air Conditioner shines with its impressive cooling capacity of 14,000 BTU, making it suitable for rooms up to 600 square feet. Its dual-hose system and inverter technology enhance cooling efficiency and energy use, which can be quite beneficial for those looking to save on energy costs. However, it does not carry an Energy Star certification, slightly affecting its perceived energy efficiency. The Seasonal Energy Efficiency Ratio (SEER) of 12.3 is good but not exceptional in its category.

One of the standout features is its low noise level of 42.5 dB, ensuring a quiet environment, which is a major plus for home use. The unit's portability is facilitated by its compact dimensions and the inclusion of a hose-in-hose design that minimizes heat leakage. Installation is simplified with the provided window installation kit, though users might still find setting it up a bit cumbersome due to its size and dual hoses. The maintenance is user-friendly, primarily thanks to the washable air filter and built-in dehumidifier with an auto drain function that handles up to 87 pints a day.

Additional smart features like WiFi control through the NetHome Plus app and compatibility with Alexa and Google Home add significant convenience, allowing remote operation and voice control. These technological integrations can be particularly appealing to tech enthusiasts. The Whynter NEX offers powerful and efficient cooling with smart features, although it may require some effort in installation and lacks the highest energy efficiency certification.

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.
