Best Portable Air Conditioners of 2025

"I have a large room, and this unit keeps it very warm in winter and cool during summer. It works amazingly and quickly!"

"I needed a portable unit after my central air system failed. This one cools just as well as my old system, and the setup was fairly simple. It's a bit louder than I expected but overall, it's a perfect solution."

"After months of struggling with the heat, I finally got this unit. The setup was incredibly easy, and it fits perfectly in my room. The noise is like white noise, not distracting at all. I wish I had bought it sooner for a comfortable temperature!"

"Unpacking was a bit tricky for me since I was using only one hand due to an injury. I realized too late that I could have lifted the box instead of tearing it apart. A simple card with unpacking instructions would have been helpful. However, setting it up was incredibly easy! The only challenge was attaching the tube, which I had to stretch just at the end while holding the rest compressed. Once it was on, the unit felt really sturdy. When I first turned it on, it was quite powerful, cooling my room from 83° to 65° in about 25 minutes. I appreciate the adjustable airflow direction and its claimed energy efficiency of only adding $77 annually to my bill. I did have to deal with condensation, so I placed a small trash can next to it since my water bottle filled up quickly. Overall, it works well, though the window panel was a bit of a hassle to fit."

"After my central A/C went out, I got the Coolbus and set it up in my upstairs area, which was quite warm. Within hours, it removed a gallon of water from the air, and I was impressed with how well it cooled my space. I initially set it to 69° but adjusted to 70° for when I went to work. I didn’t expect it to draw out so much humidity, so I used a large container for drainage, which ended up being dry when I returned home. My house is around 1600 sq ft, and this unit has been a game changer. If anyone is unsure about buying a portable A/C, I’d say go for it! They are easy to install and move around."

"I've only had the Coolbus for a day, but it made a significant difference in my sleep last night. Our upstairs tends to heat up, and we used to blast our central AC just to keep it cool enough. With this unit, we comfortably slept while keeping the whole house AC set higher, which should help save on our electric bill. The delivery and packaging were top-notch, and I found the setup quite straightforward. Just make sure the vent hose is fully uncrimped for easier attachment. I set up a bucket for drainage, but surprisingly, there wasn't any water after the night. The unit has a reliable temperature control and cools quickly. For the price, I feel this was a great investment!"

"I work from home, and my office gets extremely hot, often reaching 100-110° with all my computer equipment. After trying a Honeywell unit that failed to cool the room, I upgraded to the Wynter 14,000 BTU portable AC, which worked but was quite loud and costly on my electric bill. Finally, I switched to the Black&Decker 14,000 BTU unit, and I was impressed! It cools the room quickly and maintains a comfortable temperature. It's much quieter than my previous units, and I can even take calls without shutting it off. I also love the hose connection; it’s fool-proof compared to what I've used before. My only minor complaint is that the remote control screen could use some illumination, but it's not a huge issue for me."

"I tend to run my portable AC for 14-16 hours a day during the summer months. After purchasing the Black&Decker unit in August, I’m optimistic about its longevity; my last one lasted a decade. I'm not yet sure about the electric costs since I haven’t used it long enough for a comparison, but I expect it to be lower due to its shut-off feature after cooling. Overall, very pleased with my purchase, especially since I got it for a significantly lower price on Amazon compared to other retailers."

"Living in Texas, I needed a reliable A/C unit during summer outages. I purchased the Westinghouse 12,000 BTU floor A/C and it cools my living space effectively. The setup was straightforward, and it's impressively quiet, allowing for easy conversations. The remote control and smartphone app are fantastic features that enhance usability. Overall, I'm very satisfied with my purchase!"

"I replaced a different brand's A/C in my sunroom with this one and it turned out to be an excellent choice. It not only produces more heat but is also much quieter than the previous unit. I would definitely recommend this product!"

"This portable A/C unit features a lovely design and works efficiently to cool a large area. However, I found it to be a bit noisier than expected. Installation was quick and easy, and I appreciate that I can store it away easily when the season ends."

"I really appreciate the compact size of this air conditioner. It's lightweight and portable, and it operates so quietly that I can still hear the TV or radio while it's running. The settings for low, medium, or high are so convenient, and I love being able to use it on my patio during hot summer days. This mini portable air conditioner is definitely a must-have!"

"I've found this to be a legitimate evaporative cooler. Unlike other products that just blow mist, this one actually cools the air, making it effective in lower humidity. The fan moves a decent amount of air on high mode, and it performs even better in hot, dry conditions. While there are some minor drawbacks, like the dripping noise and lack of a water-level sensor, I think it's a great value for the cooling it provides."

"This air cooler looks a bit different from the product photo, but I really like its compact size that fits well in my corner. The remote control is fantastic, allowing me to adjust settings easily. It does a good job cooling a medium-sized room, especially when using ice packs, which seem to last longer than ice cubes. Overall, for a windowless cooling unit, it's a great choice at a decent price."

"I find this AC to be great! It's a bit loud when it kicks on, but the cooling power is strong. It cools my entire one-bedroom apartment effectively, and it fits neatly next to my TV stand. I only had trouble with the window slide being too long, but overall, I'm so cozy now and haven't had to drain any condensation yet!"

"The setup for this unit was easy, and it immediately began to lower the temperature in my sunroom. I've had it for months with no issues. The 12,000 BTU size is just right, and I've noticed my electric bill is lower since using it. The noise level is similar to a window unit, but that's not a problem for me!"

"This unit arrived well-packed, and I could tell the parts were of high quality. Although the window adaptor was initially too big for my window, I managed to make it work. I would definitely recommend this product and would purchase it again!"

"I am extremely happy with my SLPA8 AC unit from Serene Life. It effectively cools my 10x10 office, making it bearable even during the hottest days last summer in Seattle. I find that I only need to run it 15 to 20 minutes to achieve comfortable conditions. The setup was straightforward, although I had to customize the window louver to fit my window. The unit is rated at 57 dB, which I find manageable, as my Zoom calls remain unaffected. I’m very satisfied with this purchase!"

"I absolutely love this portable AC unit! It was very easy to install, and I was impressed with how well it fits my window without any gaps. The operation is quite quiet compared to my previous unit, and it cools my living space effectively. The delivery was prompt, and everything arrived in perfect condition. Overall, I would highly recommend this product to anyone looking for an effective air conditioner!"

"I live on a lake, and despite the constant humidity, this unit cools my living area and bedroom perfectly. The installation was a breeze, and I'm pleased with how well it functions. The only minor downside is that it can be a little noisy, but it’s manageable for me. Overall, I think it’s a fantastic product!"

"I love how small it is, making it perfect for my office or when I'm working from home. It's also great to take to the RV and handy during power outages. The cold air it expels is impressive, and being wireless with a USB is a huge advantage. Plus, the spin function and three speeds make it even better. Highly recommended!"

"When I got this to keep my bedroom cool in the summer, I was surprised at how well it adds humidity in the winter too. Since purchasing it in January, it’s been perfect for my plant room. The water pump circulates moisture beautifully without any noise. The ice packs included are fantastic for keeping the water cold in summer. I can’t wait for the cool breeze it’ll provide when the heat hits!"

"I never knew a portable AC could be this effective! It’s perfect for both camping and my bedroom. I 100% recommend it!"

"I am really impressed with the portability of this Portable Air Conditioner. It's small enough to carry around, making it perfect for indoor use or even for camping. The three adjustable gears provide a strong and cool wind, which adds to my comfort. Plus, I love that it can also function as a humidifier, which is essential for dry air. Its attractive design is the cherry on top!"

"I decided to give this air conditioner a try since my room doesn't cool well. I was thrilled with its three power modes and the cold mode. It's also lightweight and comes with a remote control, making it super convenient. I highly recommend it for smaller rooms!"

"This little personal evaporative air cooler is fantastic! It has three speeds to choose from and doubles as a humidifier, which is great for hot summer days. The LED light with seven colors adds a nice touch to the ambiance. I mostly use it in my room, but it's so compact that I can easily take it outside. Overall, it's been a solid purchase!"

“I love this air conditioner! I was torn between a window unit and a standup, but decided to give this a try. It cools the room down really well and is also pretty quiet. Great choice for standalone A/C. I would definitely recommend it!”

“I’m someone who tends to feel hot all the time, and I’m really pleased with how well this product cools the room. I can fill the water tank, and it runs for a long time. It’s very quiet too!”

“I bought this fan mainly to keep mosquitoes away while I work on the farm. The power is perfect for blowing them away, and I use it daily during meals and when I’m resting. The battery lasts a long time, and it’s easy to carry around with its handle.”
