This list was compiled by analyzing the data of over 50 small AC units, including manufacturer information, expert reviews, and customer feedback all in the name of determining the very best small air conditioner. All units were also judged according to how well they performed in three areas: energy efficiency, safety, and functionality.
In other words, are they worth the cost and are they energy-efficient? Are they safe to use all day every day? And are they easy to use and functional? We put those results together and came up with this list of the absolute best small air conditioners that won’t let you down.
1. LG LP0817WSR Portable Air Conditioner
LG’s sleek and powerful portable air conditioner has landed itself on the very top of this list, and deservedly so. Among the smallest of the air conditioners offered by LG, this remote-controlled AC unit can still cool a room of up to 200 square feet and can be used all day without the need for draining.
Its impressive cooling ability is aided by an auto evaporation system and an auto-swing function that evenly distributes cool air to a room, which means you won’t have to worry about certain parts of the room being hotter than others.
And because it is a small portable air conditioner, it can very easily be moved to any part of the home you want to be in, from the kitchen in the morning to the bedroom at night. This LG unit also comes with three modes to suit your needs at any time of the year. The cooling mode is perfect for hot and humid days, but you can also choose the fan mode when you need air circulated or the dry mode for damp rainy days.
Its auto-swing function also means that it can keep a room at a consistent temperature for long periods of time, eliminating the need to adjust the temperature every few hours. It is truly an air conditioning system that has evolved to meet your needs at every turn, which is why it is undoubtedly the best small air conditioner (and best portable AC) available on the market.
2. Frigidaire FFRA0511R1E Mini-Compact Air Conditioner
This small but mighty AC unit may be one of the most popular air conditioning units out there because of the excellent way Frigidaire has combined effective results and good pricing in one unit. The Frigidaire FFA0511R1E can cool up a room of up to 150 sq. ft. to your desired temperature in a matter of a few short minutes and it has a 1.1 pints per hour dehumidification system.
Unlike other bigger units that can very quickly eat up the bulk of your power bill, this mini-unit boasts excellent energy ratings that won’t break the bank during the hottest days of the summer. It has a low power start-up and an easy reset system to make using this unit all day safe and efficient. This alone makes it a very worthy contender for the title of the best small air conditioner, even though it is not necessarily portable.

Your Possible Questions, Answered
1. What is the Most Important Factor to Consider When Choosing a Small Air Conditioner?
What you are looking for will ultimately depend on your own needs and what you prioritize (for instance: price, energy-efficiency, noise, etc.). If this is your first time buying a portable air conditioner, it may help you to list down the things you want from it and organize your choices according to how closely they match that list.
But with this buying guide that we have put together, we ranked AC units based on three things that we find most important for small air conditioners: energy efficiency, safety, and functionality.
Is it cost-efficient in how it uses your power? Is it safe to use and leave on? And does it have the functions people need to make air conditioning easy? Going from a traditional central AC unit to a small portable AC may be confusing, so we find that these three basic factors can cover a whole range of concerns.
2. What Are the Benefits of Switching to a Small Air Conditioner?
Small air conditioners are ultimately the better choice when you’re looking to cool a small space like a bedroom, a small apartment, a small home, or an office. Not only does it take up less space than a central AC unit, but it can also be stored away when it is not in use, further cutting down on the space it takes up.
It can also match or even surpass the cooling power of bigger ACs while using less energy and costing you less in bills. And if you choose a small air conditioner that is portable, you can easily move the unit to where you need cool air.
3. What is the Difference Between a Single-Hose and Dual-Hose Portable AC and What Should I Get?
Going through our list, you may have noticed that some of the small ACs have single-hose designs while others have dual-hose designs. Single-hose AC units take air from inside the space, cool it, and release most of the air back into the room. The rest of that air is used to cool the inside of the machine and the resulting hot air is then released outside through the single hose.
This means that the machine will have to constantly work to “replace” the air that was taken from the room and pushed outside. On the other hand, a dual-hose AC unit has one hose to take in air from the outside that is cooled inside the machine and released in the room and another hose through which hot air and moisture is released. This means that air conditioning is done more efficiently.
But ultimately, which one is best for you will still depend on your needs. If you have a small space, then a single-hose AC will work perfectly well. But if you have a large space, then you may find better cooling results with dual-hose portable AC units.
4. How Much Power Do I Need?
The power you will need from your small room air conditioner will depend on the size of your space. We recommend choosing a unit that fits your needs exactly to find the best small air conditioner for you, instead of underestimating or overestimating the power you need from your small air conditioner.
Generally speaking, units with 8,000 BTU can cool a room of up to 200 sq. ft., 10,000 BTU units can cool a 300 sq.ft. space, 12,000 BTU units can cool a 400 sq. ft. space and 14,000 BTU units can handle spaces of 500 sq. ft.
5. Does the Size of an AC Unit Matter?
This will ultimately depend on your needs. Generally speaking, the size of a unit should not affect its performance so it will be up to you to decide if the size does not matter or if you want the smallest air conditioner in the market.
But if you have a small space, you should consider that some larger units may be difficult to store away or even move around. And if you have a large space, you may worry that portable air conditioners on the smaller side may not be able to cool your large space as fast as a bigger one might be able to.
6. Do I Need All These Extra Digital Features That Come With Small Air Conditioners?
Yes and no. While you probably will not be too negatively affected by the lack of, say, remote control or an auto-draining system, they can definitely make your life easier. For example, remote control capabilities mean that you can control your mini AC even from across the room, saving you the time and trouble of walking over to it every time you want to adjust the temperature or turn it off.
Similarly, timers, which come built-in in many units, help cut on energy use by allowing you to choose exactly when it will turn on and when it will turn off without lifting a finger. For extra digital features, the rule of thumb is to consider how often you plan to use the unit, whether it will be your primary cooling source, and whether you have the time to manually drain it.
So if it is to be your primary cooling appliance, you may want to spend a little more to get the best features. And if you do not think you will always have time to drain the machine, then an auto-evaporation system is necessary for your own safety. It will ultimately depend on you but sometimes, it can be worth it to spend a little extra on the best small air conditioner possible to make your life a little easier.
