It’s currently 82 degrees, sunny and so humid I can feel the air settle against my skin like a weighted blanket. Tack on trying to achieve my ‘summer body’ that means visits to the gym and barn to see my pony, and I can’t seem to stay cool. It’s still early June, and that means the current temperatures are only the harbinger of summer heat and humidity.

If you’re looking to cool down a hot room, garage or pet area, a portable air conditioner could be a better investment option versus a standing fan. It ultimately depends on your budget, venting options, area size and chilling requirements. So if you’re new to portable air conditioners, we highly recommend checking out our complete beginner’s buying guide, which includes some helpful tips on proper BTU size, ventilation kits and some top picks of 2025.

What The Reviewers Are Saying

“Love it!” exclaims one reviewer, saying “This is the absolute coolest air conditioner I’ve ever used…I went with a less expensive model in a different brand, it didn't work as it should and [I] had to send it back. Since it was loud and I had to empty my water bucket twice a day, I decided to up my game and splurged little more and bought this.” They went on to mention that installation was easy - the only thing they’d change is some of the color options.

Another reviewer who lives in Arizona says, “I was worried about all the horror stories people report using these types of units. Turns out it just works, and works pretty well. We have about a 200 sq. f.t master bedroom and it takes about two to three hours to get it down to 72 degrees.” They mentioned they did not need to empty water in a month just using the AC feature.

One more says “it gets the job done”, and that it cools the room fast and stays cool consistently.

The most common complaints were around the power size - some felt like the lower BTU options are just not enough power to cool large room sizes. A few felt it was a little expensive, while another review noted it was tough on their power bill.

More Dreo Portable Air Conditioner Options

If you don’t necessarily care about snagging an AC at the lowest price point, there is a 10,000 BTU and 14,000 BTU option from Dreo that can power those larger room sizes.
