While installing air conditioning in your home can help keep the breezy coolness you need, it can be expensive to fit an AC unit in every room of the house. Portable air conditioning units give you the possibility of zonal cooling in your home. As you are able to move the units from room to room, you can enjoy cool, fresh air wherever you are.
However, to keep from buying anything too cumbersome or space-guzzling, it is important to consider the most effective AC units for their size. Here’s our guide to the finding the smallest portable AC units worth their salt!

Finding a Small AC Unit for Your Space
If you don’t have central air conditioning in your home, you might be looking for something to help break the sweaty monotony of the heat. Employing a small, portable AC unit to do the job is a great idea. Additionally, if you’re finding that the central system in your home doesn’t really do the job, purchasing a small AC unit to supplement will keep air flowing more effectively.
The excellent thing about finding small portable units is the ability to move them around. If you’re a person who works out in their garage or workshop, you may want to put use a portable unit rather than installing something more comprehensive, as you use the space less frequently. In this case, the smallest portable AC units are easy to store away.
For others, you may find you don’t have a suitable window to install air conditioning. In this case, using a small portable AC unit will suffice in place of a central system.
What to Look for in a Small AC Unit
When shopping for an AC unit, your first priority may be to find something small and portable. However, there are a range of things to consider:
Power capacity is extremely important. If you select something too small, you’ll find that it won’t have the power to actually cool the room you desire. However, if you buy something with too much power, you’ll forever be turning it off to keep from freezing. This may cause a large amount of wasted energy and money.
Consider the BTU rating to understand the output power of each unit. While this may vary between manufacturers, you can also look for indications that show the square foot of cooling capacity. As a rule, you need 1800 BTUs per 100 square feet.
If you’re looking for something portable, you need to consider size. A unit too cumbersome will be a pain to transport about, especially if you’re trying to fit it into a vehicle. Equally, you need to look for a unit that isn’t too heavy, otherwise lifting it may cause injury.
Consider the features such as whether it has a carry handle or wheels, as this will make it easier to move.
Cooling units with overheat protection and tip-over safety measures tend to have longer lifespans.These features help to reduce the risk of fire, while protecting the components inside the unit. Especially important for those with pets and children, you must ensure you have a unit that doesn’t get too hot while in operation. Read our buyers guide for the best heater for baby room here.
Energy efficiency refers to the amount of power that a unit needs to cool the room and the expense of that power. Units with good energy ratings or bearing the Energy Star seal are usually a little more expensive upfront but tend to have lower running costs as they utilize energy more efficiently.
When selecting an air conditioning unit, you need to consider the hose drainage. Single-hose AC units use only one hose for both the air intake and exhaust. These are less efficient as they need to work harder than dual-hose AC units. Dual-hose AC units have separate intake and exhaust hoses. These models cool ta room faster and are more energy efficient, yet tend to cost more upfront.
The condensate type that you select for your AC unit can determine how easy it is to use. Drip air conditioning units work by allowing the waste condensate to drip into a bucket inside the unit, which then needs to be emptied when full.
Alternatively, you can have an air conditioner that doesn’t drip, instead, it releases the condensate into the room’s atmosphere. These units tend to be more popular due to ease of use.
You can also find a hybrid of the two designs that needs emptying less frequently as most of the condensate is released back into the air.
The filtration system in portable AC units is designed to keep out airborne particles such as dust or spores. Some models even come with built-in air purifiers. This helps reduce the humidity in the room as well as ‘conditioning’ the air for a cleaner atmosphere.
You need to clean the filters in these units to ensure that their ability to do this job effectively. Doing it once every two weeks is a good idea, as this will stop them from clogging. Blocked filters prevent the AC from cooling the air as they cannot suck in air effectively. This leads to reduced effectiveness and higher energy bills as the air conditioner works overtime in an attempt to cool the air.
