Best Air Conditioners of 2025

"I've been using this unit 365 days a year and have no complaints. It's decently priced and does the job."

"I was surprised at how well this air conditioner works in my small bedroom. It cools off both the bedroom and the room next to it when the doors are open. Plus, it looks great in my window."

"This air conditioner is powerful and exceeded my expectations. I used it in a difficult space and managed to cool down the entire upstairs of my old house."

"I work from home, and my office gets extremely hot, often 15-20° warmer than outside. After struggling with a Honeywell 8,000BTU unit that couldn't keep up, I switched to this Black&Decker 14,000BTU portable AC. It cools the room in minutes and keeps it comfortable throughout the day. Much quieter than previous models, I can even talk on the phone while it's running. The hose connection is also a significant improvement—it locks in place and doesn’t fall off like my old units."

"While I’ve only had this unit for a short time, I’m optimistic about its longevity. I use my portable AC for 14-16 hours daily from April to October. If it lasts as long as my last unit, which was a decade, it will be a smart investment. Also, I’ve noticed that it shuts off after cooling, which should help lower my energy costs."

"The only minor downside is the remote control design. The LCD screen needs better illumination; it’s hard to read in dim light. However, this is a small issue compared to the unit's performance. Overall, I’m very pleased with my purchase, especially since I got it for a lower price on Amazon than anywhere else."

"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 bought this for my master bedroom and it works great! It's quiet, and the remote works perfectly. My room stays a comfortable 68 degrees even when it's 100+ degrees outside. I would definitely purchase it again!"

"I purchased this for my daughter's small apartment in Toronto. She loves it! It's very quiet and keeps her bedroom cool during the night while controlling the temperature in her 4-500 sq foot apartment nicely. Great value for money!"

"This unit arrived just in time for a heat wave, keeping my room and living area cool even when temperatures soared to 106 degrees. It was easy to set up, and I recommend it to anyone looking for a window unit at this price!"

"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!"

"Installing this AC was a bit tricky at first, but totally worth it. It's incredibly quiet!"

"I thought I ordered a unit with heat, but it only has AC. It's easy to install and works well for cooling."

"I bought this unit last year, but now the back fins are rotting. Midea won't service it since it's past the one-year warranty."

"This AC is very quiet and cools the room quickly. The initial setup was a bit complicated, but after three years, I can do it almost in my sleep. I'm really pleased and hope they maintain this quality!"

"I was thrilled with the quiet operation of my Senville unit. It cools my 12x14 room down to 62 degrees within ten minutes on a hot day. I was even able to set it up temporarily with an extension cord while waiting for the professional installation. My installer friend, who has 32 years of experience, was impressed with the quality for the price. I wish I had done this sooner, especially now that my baby is comfortable during naps!"

"I found the Senville to be a high-quality product that performs exceptionally well. However, I recommend doing thorough research and having the right tools since the installation can be a bit challenging. While the physical installation was straightforward, the wiring and line set installation were time-consuming. Pressure testing is crucial, and I was glad I took that extra step to ensure everything was leak-free. After 22 months of use, I’m very satisfied with its performance in my garage, regardless of the outside temperature!"

“I purchased this to replace my overworked 6k BTU unit for my living room. It keeps the room very cool, and I appreciate how it kicks on and off as needed, helping me save money. Although it arrived with minor damage, this was due to UPS. I was really impressed with Amazon's customer support regarding this issue! I should have bought two!”

“I initially bought this for emergencies, but I love it so much that I use it daily. Living in an area with power outages during monsoon season, I needed an energy-efficient AC for my solar generator. This unit performed perfectly during my stress test, using only 9W in ECO mode. I did use a small USB fan to circulate the air better, but it's not necessary. It’s a great option for an RV, tiny home, or bedroom.”

“After my previous unit failed during a heat wave, I was eagerly waiting for this one. It's been phenomenal at cooling my large bedroom since it arrived. The setup was easy, and I couldn’t be happier!”

“I purchased two of these units during a sale, and they have been fantastic. My mother and I are enjoying the much-needed cold air during this heatwave. They are relatively lightweight, making them manageable, but having someone help with placement is ideal. The long cord is a bonus, and the cooling output is impressive.”

“I've been using this A/C in my single-room studio for less than a year, and it has worked wonderfully during the summer. I noticed it moves liquid around internally, so I installed it slightly tilted to let excess water escape outside. It uses quite a bit of power, but I found that running it for 20 minutes keeps my room cool for hours.”

“This unit cools off our medium to large bedroom nicely, even during heat waves. It’s designed for single-room cooling, and while some reviews mention using it for larger spaces, it doesn’t work that way for us. We didn’t expect it to, and it does its job well for the price.”

"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!"
