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.

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 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.
