Portable air conditioners fill a much-needed role within the mobile A/C market. They're a practical choice for anyone who needs a flexible, easy-to-move cooling solution without a permanent setup, and they're generally simple to install and store between seasons. When shopping for one, though, you'll want to look for a few key features to make sure you're getting the most out of your investment.
The best portable air conditioners are designed to deliver more consistent cooling with features like dual-hose designs, which help keep cooled air separate from warmer outdoor air. They also often use inverter compressors, which, like a dimmer switch, allow the unit to modulate its output and maintain a steady temperature by running continuously at a lower speed. Beyond cooling performance, it's also worth considering noise levels. Since the compressor sits inside your living space rather than outside like with a window unit, sound can be a greater concern than with a traditional window or central system. Any added convenience features, like programmable timers or app control, are worth factoring in as well.
We've tested 20 air conditioners with more on the way, and below are our recommendations for the best portable air conditioners on the market. These recommendations are based on their performance, feature set, price, and availability. If you're looking for an alternative and have the space and ability to install one, it's worth checking out our recommendations for the best window air conditioners, as they tend to be more efficient overall and can cool spaces more quickly and consistently than portables A/C's. Alternatively, if you want a broader overview of the A/C market, see our recommendations for the best air conditioners and the best air conditioners for bedrooms.
Behind all of our air conditioner recommendations are our product reviews. We buy our own air conditioners directly from major retailers and have our team rigorously test them in our lab. The result? Robust data on features you care about, like cooling capacity and inside noise, which you can then compare across the 20 models we've tested.

Best Portable Air Conditioner
Large Room8.0Bedroom/Small Room7.6Combined Efficiency7.7Oversizing Tolerance8.1Noise8.4Type:Dual-Hose Portable A/CAdvertised Capacity (DOE):12,000 BTU/hrTested Capacity:9,256 BTU/hr (2,714 W)See all our test resultsCompressor Technology:InverterThe best portable air conditioner we've tested is the Whynter NEX ARC-1230WN. This high-end unit has a tested capacity of around 9,000 BTU/hr, giving it enough cooling power to handle even big open-concept living spaces all by itself. Despite that output, it runs impressively quietly for its size, so it won't be overly intrusive in shared spaces. It also packs in everything you could want from a portable A/C. It has built-in Wi-Fi, so you can control it or check the temperature at home remotely through the NetHome Plus app. It also works with Google Home and Amazon Alexa so that you can adjust the temperature or fan speed with a voice command. On top of that, there's a dedicated dehumidification-only mode for humid days when you don't necessarily need cooling. Its two-in-one hose design is more compact than most dual-hose models, so it's easier to move between rooms since there's less to set up.
The one thing you can't get around is the size: this is still a genuinely bulky appliance, so if floor space is tight, that's worth keeping in mind. That aside, it doesn't suffer from the same oversizing issue that plagues non-inverter models. Its inverter compressor can run at a lower speed instead of cycling on and off when maintaining your desired setpoint, which gives it enough time to properly dehumidify the air as it cools. The result is a room that feels comfortably cool and dry rather than cold and clammy. If you're dealing with a large, humid space and want a portable unit that can actually keep up, the Whynter is about as good as it gets in this category.

Best Upper Mid-Range Portable Air Conditioner
Large Room7.7Bedroom/Small Room7.8Combined Efficiency7.3Oversizing Tolerance8.4Noise8.6Type:Dual-Hose Portable A/CAdvertised Capacity (DOE):10,000 BTU/hrTested Capacity:7,533 BTU/hr (2,209 W)See all our test resultsCompressor Technology:InverterIf you have a smaller space and don't need the sheer capacity the Whynter NEX ARC-1230WN offers, the Midea Duo MAP12S1TBL is a slightly more affordable option that delivers a similar feature set. It has a tested capacity of around 7,500 BTU/hr, making it a better fit for bedrooms or average-sized living spaces. The two units are actually nearly identical under the hood: they share the same digital interface, and Whynter's NetHome Plus app is effectively a reskinned version of the Midea Air smartphone app. It also shares the same space-saving two-in-one hose design. Its inverter compressor allows for relatively efficient operation with minimal swings in temperature or humidity while maintaining your desired setpoint, which is particularly useful in humid climates where keeping moisture levels stable matters as much as the temperature itself. It's also quiet enough to leave running in the background while you're watching TV or trying to sleep.
The main area where it falls short is cooling capacity, which runs about 20% lower than the Whynter. In practice, this means it'll take a little longer to cool a comparably sized space, so if you're trying to bring down the temperature quickly in a large room during a heat wave, you may notice the difference. For most bedrooms or average-sized living spaces, though, it's more than capable and unlikely to leave you wanting more.

Best Mid-Range Portable Air Conditioner
Large Room5.6Bedroom/Small Room7.0Combined Efficiency4.5Oversizing Tolerance7.7Noise6.7Type:Single-Hose Portable A/CAdvertised Capacity (DOE):7,000 BTU/hrTested Capacity:3,540 BTU/hr (1,038 W)See all our test resultsCompressor Technology:Non-InverterThe LG LP0721WSR is worth a look if you're shopping at a mid-range price point. It has a tested capacity of just over 3,500 BTU/hr, making it best suited for small to medium-sized rooms like a bedroom or a cozier living space, but not anything larger. It's also well-rounded on the features front. There's a dedicated dehumidification mode for muggy days when you want to take the edge off without dropping the temperature, a digital thermostat for precise temperature control, and a remote control so you can adjust settings without getting up.
Although the single-hose design does cut down on bulk and makes setup straightforward, it comes with trade-offs. It pulls air from inside the room to cool itself, which drags warm air back in from outside and forces the unit to work harder than it should. It also produces a fair amount of noise during operation, which can be noticeable in quieter environments like a bedroom or small office. It's also worth keeping it out of oversized spaces, as running the compressor continuously in a room that's too large will accelerate wear over time. That said, if your cooling needs are modest and you want a feature-rich unit for a smaller space, it's a solid option worth considering.

Best Budget Portable Air Conditioner
Large Room5.1Bedroom/Small Room6.2Combined Efficiency4.9Oversizing Tolerance7.5Noise4.4Type:Single-Hose Portable A/CAdvertised Capacity (DOE):4,000 BTU/hrTested Capacity:3,335 BTU/hr (978 W)See all our test resultsCompressor Technology:Non-InverterIf you're on a tight budget and only need to cool a small space, the SereneLife SLPAC8 could be right for you. With a tested capacity of around 3,000 BTU/hr, it's best suited for a bedroom or office. For a unit this basic, it's a welcome surprise how feature-rich it is: there's a remote control so you can adjust settings without getting up, a dedicated dehumidification mode for humid days when you don't necessarily need full cooling, and a digital thermostat for precise temperature control.
The main drawback of this unit is its noise: while the LG LP0721WSR is no whisper itself, the SereneLife is a step beyond that and can become a genuine nuisance in a quieter setting like a bedroom or small office. It occasionally produces brief bursts of noise exceeding 78 dBA, which is roughly on par with a vacuum cleaner and loud enough to interrupt a conversation or pull your attention away from what you're watching. Its single-hose design also forces it to work harder than it should, which takes a toll on efficiency. That being said, if noise isn't a dealbreaker for you and you just need something basic to cool a small space on a budget, it gets the job done.

LG DUAL Inverter LP1419IVSM:
The LG DUAL Inverter LP1419IVSM is a high-end portable A/C unit designed for medium- to large-sized spaces. It features a somewhat unique selling point: a dual-inverter compressor that operates at variable speeds rather than cycling on and off. Unfortunately, this unit is hamstrung by its single-hose design, which severely compromises its efficiency compared to dual-hose models like the Whynter NEX ARC-1230WN.
