Best Portable Air Conditioners of 2026

"I've been using this unit in my 700 sq ft bonus room filled with electronics, and it keeps the space at a comfortable temperature even during the hottest days. Although it's louder than I expected, I haven't found another portable AC of this size that can cool as efficiently without running non-stop. Would definitely purchase again."

"This air conditioner was simple to set up and fit perfectly into our garage workspace. The noise level was lower than I thought, and the remote control and sleep timer make it super convenient. It really made the space much more comfortable during hot weather."

"I've had some trouble with the water drainage—the hose is a bit short, and if I don't keep an eye on it, it can fill up and turn off the AC. The unit does cool a small room well, but you have to stay on top of maintenance. It does its job, but the design could be improved."

"I mainly use this as an A/C, but the heating feature works well for supplemental warmth in winter. The fan is powerful, and the cooling is very effective during hot months. I find the noise level completely acceptable. The remote and timer are handy, and I like it so much I bought two of them."

"I picked this up to replace my old portable A/C and was impressed right away—the airflow, even on the low setting, is outstanding. I love how it cools my open kitchen, dining, and living area effortlessly. Yes, it’s a bit noisy, but it’s nothing unusual for an A/C, and the remote makes it super convenient."

"I installed this unit myself without any issues—everything needed was included. After several weeks of use, it’s been running at 100% with no problems. The installation was simple, and the flexible exhaust tube is helpful for directing airflow. So far, I’d say it’s totally recommendable."

"I've had this machine for years and it's honestly been the best addition to my Florida home. It keeps my 15x15 room cool, even with computers and podcasting gear running constantly. Noise isn't an issue for my recordings, and the filter is a breeze to clean. I love that I barely ever have to empty the water. Even after 7 years, it's still running strong—I’m extremely satisfied with my purchase!"

"Living in San Antonio, Texas means brutal heat and humidity, but this AC quickly cools my 500 sq ft bedroom by over 10 degrees, even when it's 100°F outside. The hose and window kit work perfectly, and the noise is just like gentle white noise—not intrusive at all. I don't notice any spike in my energy bills, and the condensation is practically nonexistent. Highly recommend for anyone needing serious cooling."

"As someone who is disabled and works from home, this unit has been a lifesaver during heatwaves. It's easy to set up and move, keeps my entire top floor comfortable, and the filter maintenance is simple. It even handled a flooding emergency thanks to the dehumidifier feature. Truly one of my favorite purchases."

"Working from home with lots of computer equipment makes my office extremely hot, but the Black & Decker 14,000 BTU unit cools the room quickly and maintains a comfortable temperature all day. Compared to previous units, this one is noticeably quieter, and the hose attachment is much more secure. While I wish the remote control screen was easier to read in low light, that's a small trade-off for such a solid performer."

"After my central AC failed, I relied on this portable unit and it kept my space cool and comfortable even in humid weather. The setup was surprisingly simple, and the unit handles multiple small rooms well, lowering both temperature and humidity. The unit is a bit heavy and makes some noise, but nothing out of the ordinary for this type of AC. It’s saved me a lot of money compared to replacing my central AC right away."

"After using this Amazon Basics air conditioner for a couple of months, I can say it's been a huge relief during hot days. Setup was straightforward, the controls are very intuitive, and it cools my room quickly and quietly. I love that it keeps a consistent temperature without wasting energy, and the design is clean and unobtrusive. Overall, it's been effective, affordable, and reliable—just what I needed."

"I picked up the 5000-BTU unit for my bedroom, and it's become an essential part of my smart home setup. Installation was incredibly easy and the mechanical controls make it perfect for use with a smart plug. It cools my room quickly, and the washable filter makes maintenance simple. While it's not the quietest, the white noise is actually soothing for sleep. For single rooms and automation, it's a fantastic value."

"My room is about 120 sq ft, and this AC unit is powerful enough to cool it down in about 10 minutes. Installation was quick and secure, and the price was great. It's a bit noisy—I notice it especially when my desk is close to the window—but for what I paid, I have no complaints. Solid performance for the cost."

"I have asthma and hay fever, so finding an AC that actually delivers fresh, dry, cool air is a big deal for me. This Black & Decker outperforms my building's HVAC—it's super quiet, easy to move from room to room, and the installation was genuinely a breeze thanks to the thoughtful window panel design. The slim, boxy shape fits perfectly in my space. I'm so pleased, I'm thinking about getting another for a different room."

"I use this portable AC on the hottest, most humid nights at my coastal home. It was set up and running in under five minutes. The compact size fits my small bedroom perfectly, and it cools the space quickly. The timer function is a great bonus, letting me cool the room and then have it shut off automatically. Would definitely buy again!"

"I needed something that could make my bedroom comfortable again after temperatures soared above 90°F. This unit did the job—installation was straightforward, though the hose attachment instructions could be clearer. It's a bit on the loud side, but to me, it's just like a box fan. For the price, it’s absolutely worth it."

"I’m seriously impressed with how well this AC cools my 850 sq ft house—it keeps my kitchen and living room up to 20 degrees cooler than outside, even with kids running in and out. If you have a small home or need to chill a big room, this unit is awesome."

"After getting tired of heavy window AC units in my apartment, I tried this portable one. Setup and maintenance are simple, and my bedroom is cold all night long. The only thing to watch for is humidity—it can make water, but the constant drainage option works well for me."

"I learned the hard way that you should crack a window when using this AC! Once I did, my whole apartment became cool and comfortable. Before that, it didn’t cool as well and I noticed a weird smell. Now, it works excellently—just remember to let in a bit of fresh air."

"When my central HVAC system failed during the hottest part of summer, I picked up this Black & Decker portable air conditioner. It cooled my large bedroom from 90° to 68° in no time and kept my pets and family comfortable. Setup was a breeze; I managed it solo in minutes. The unit is robust, running for months without any issues, and I love that it's on wheels for easy movement between rooms. My only small gripe is that the remote control isn’t backlit, but overall, this AC was a lifesaver and is incredibly durable and efficient."

"I was skeptical after reading mixed reviews, but so far, this portable AC has been fantastic for my apartment where window units aren't allowed. It gets my room icy cold—down to 64 degrees if I want—and even helps cool multiple rooms when I leave the door open. There was a bit of a learning curve with the controls, and occasionally the switching between AC and fan modes wakes me up, but the cooling power and convenience are totally worth it. If you're worried about noise, it's no worse than a standard fan."

"I purchased this unit because my apartment's AC doesn't reach upstairs well. The Black & Decker portable AC has made our nights so much more comfortable and is easy to install. The only thing I’d mention is that the noise level is noticeable when it cycles on and off at night, but leaving the door open helps it run more steadily. Overall, I’m really happy with the purchase and recommend it for anyone in a similar situation."

"For me, the quiet performance of this little swamp cooler stands out. I can barely hear it running on low, and it quickly raised humidity in my room, making it feel much more comfortable. It's the perfect size for smaller rooms and offers great value for the price. I mainly use it as a cool air humidifier, and it does the job beautifully."

"Honestly, I found this product overpriced for what it delivers. The cooling effect is minimal, the included ice-gel packs thaw too quickly, and even adding extra ice doesn't help much. The airflow is weak, even at the highest setting. I wouldn't recommend spending your money on this."
