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 Dreo Portable Air Conditioner offers strong cooling power at 14,000 BTU ASHRAE (10,000 BTU DOE), suitable for rooms up to around 400 square feet, making it a good fit for bedrooms or medium-sized living spaces. It stands out with a patented drainage-free system that automatically evaporates excess moisture, so you don’t have to worry about emptying water tanks, which is especially useful in humid environments. Noise-wise, it operates quietly at about 45 dB, roughly the sound level of a soft conversation, so it won’t disturb sleep or work.

The unit is fairly portable with caster wheels and modular window panels, allowing easy installation in different window types. It also includes smart features like app control, voice commands via Alexa, Siri, and Google Home, and a programmable timer, which add convenience for daily use. The 3-in-1 functionality allows cooling, fan, and dehumidifying modes, covering multiple needs in one device.

Its energy efficiency ratio (SEER 5.6) is moderate, meaning it may use more power than some more efficient models, possibly impacting electricity bills. At about 65 pounds, it’s not the lightest portable option, so moving it around frequently might be a bit challenging. The included air filter helps improve air quality but may require regular cleaning or replacement over time. This unit represents a solid choice if you want a quiet, easy-to-control, and drainage-free portable AC with decent cooling power for spaces up to 400 square feet.

The Dreo Portable Air Conditioner AC515S offers strong cooling power suitable for rooms up to about 300 square feet, with a 12000 BTU rating providing fast and effective temperature control. Its noise level is impressively low at 45 dB, making it a quiet choice for bedrooms or workspaces where minimal disruption is important. This model shines with its patented drainage-free system, which automatically handles excess water, so you won't need to manually drain it even in humid conditions. The unit also includes a dehumidifier function, which can help reduce moisture in the air alongside cooling.

It features smart controls that let you adjust settings via voice commands through Alexa, Google Home, Siri, or through an app, adding convenience and customization for your cooling preferences. Portability is well-addressed by smooth caster wheels and a window kit that fits various window types, though the unit weighs around 63 pounds, so it may be less easy to move frequently. Energy efficiency is decent with a SEER rating of 6.1, but the power draw can be high at up to 1500 watts, which is common for this cooling capacity but something to keep in mind for electricity costs.

The product comes with a remote control and has a large LED display for easy use. This Dreo model represents a solid choice if you want a quiet, smart, and low-maintenance portable air conditioner with effective cooling and added dehumidification, especially for medium-sized rooms. It might be less ideal if you need a very lightweight or ultra-energy-saving unit.
