10 Best Portable Air Conditioner Towers 2025 in the United States

The BLACK+DECKER Smart Portable Air Conditioner with Heat offers a versatile 4-in-1 solution for your climate control needs. With 14,000 BTU (ASHRAE) cooling capacity and 12,000 BTU heating, it can effectively service rooms up to 700 sq. ft., making it a solid choice for larger spaces. The unit also functions as a dehumidifier and fan, adding to its utility throughout the year.

The energy efficiency ratio (EER) could be improved with a SEER of 6.2, which is not the highest in the market, meaning it may consume more electricity compared to other units with better ratings. Additionally, this model is not Energy Star rated, which might be a concern for energy-conscious users. Another highlight is its smart functionality – you can control it via a mobile app or through voice commands using Amazon Alexa or Google Assistant, adding a layer of convenience. The remote control with a 'Follow Me' feature ensures precise temperature control by acting as a thermostat wherever you place it.

At 54 dB, the noise level is moderate and should be manageable for most users but might be noticeable during quiet nights. The unit is fairly portable with dimensions of 16.5” x 14.06” x 27.09” and includes an easy-to-install window kit, making set-up straightforward. While it manages up to 375 square feet optimally, its performance might decrease in spaces closer to the 700 sq. ft. threshold especially without proper insulation. Weighing 35 pounds, it is reasonably easy to move around. Those looking for a robust, multi-functional air conditioning solution with smart features might find this product particularly appealing, albeit with a few trade-offs in energy efficiency.

The Whynter Inverter Portable Air Conditioner stands out with a strong cooling capacity of 14,000 BTU, making it ideal for large rooms up to 600 square feet. It's praised for its powerful and quiet operation, with a noise level of just 42.5 dB, ensuring minimal disturbance.

The unit is energy efficient with a Seasonal Energy Efficiency Ratio (SEER) of 12.3, although it does not have an Energy Star rating, which might be a consideration for environmentally conscious users. Its inverter technology is a notable feature, enhancing cooling efficiency by 20% and operational efficiency by 40%, which can lead to energy savings. This model includes a dehumidification function capable of removing up to 87 pints of moisture per day, making it suitable for humid climates.

The smart Wi-Fi control via the NetHome Plus app, along with compatibility with Alexa and Google Home, adds a layer of convenience for remote operation. Users will appreciate the three operational modes (cool, dehumidify, and fan) and the full thermostatic control range from 60°F to 86°F. The portability is enhanced by a dual-hose design that reduces heat leakage and an extendable hose for flexible window installation.

The Dreo Portable Air Conditioner AC318S offers solid cooling performance with an 8000 BTU ASHRAE (5000 BTU DOE) rating, suitable for rooms up to about 150 square feet. It stands out with a quiet operation at 45 dB, making it a good option for bedrooms or workspaces where low noise is important. The unit includes a patented drainage-free system that automatically evaporates excess water, removing the hassle of manual draining in normal humidity levels. Its 3-in-1 functionality (cool, fan, dry) adds versatility to adapt to different weather or comfort needs.

Users will appreciate smart features like app control, voice commands via Alexa, Google Home, or Siri, and programmable timers that simplify temperature management. Portability is well addressed with smooth wheels and a modular window kit fitting a variety of window types. The energy efficiency ratio (SEER) of 6.1 is decent for this size, helping to keep electricity use reasonable without sacrificing cooling power. While the cooling capacity suits small to medium rooms, it may struggle in larger spaces or very hot climates.

Weighing 55 pounds, it’s portable but not ultra-light, so moving it frequently might require some effort. The included air filter helps maintain cleaner air but periodic replacement or cleaning is needed to keep performance optimal. With strong customer support and generally positive user feedback, this model is a practical choice for those wanting a quiet, easy-to-use, moderately powerful portable AC with smart home compatibility. For those needing powerful cooling for bigger spaces or ultra-light portability, other options might be more suitable.
