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 Daikin 24,000 BTU 18 SEER2 Entra R32 Series Ductless Mini Split Heat Pump System is a versatile and efficient option for those seeking an alternative to traditional window AC units. With a cooling capacity of up to 24,200 BTUs and a heating capacity of up to 27,300 BTUs, it can comfortably handle spaces up to 1,500 sq. ft., making it suitable for various rooms and environments, including basements, attics, and sunrooms. The unit's high energy efficiency, evidenced by its 18 SEER2 rating and 10.5 EER2, ensures lower energy consumption and cost savings over time.

Additionally, it operates effectively in a wide range of temperatures, providing reliable performance in different climates. Portability is enhanced by the comprehensive installation kit and wall mounting bracket, allowing for flexible placement without the need for extensive ductwork. The inclusion of advanced features like ECO+ mode for energy efficiency, Blue Fin Protection for durability, and an air purifying filter for improved air quality enhances the user experience.

The unit is not Energy Star rated, which might be a consideration for those prioritizing energy certifications. The Daikin Entra system offers robust performance, excellent efficiency, and convenient installation, making it a viable choice for those needing efficient climate control in non-window AC unit installations.

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.
