Best Small Portable Air Conditioner

7 Best Small Portable Air Conditioner of 2021 (Reviews & Buying Guide)

There are lots of reasons to enjoy summer, but all of them appear to revolve around hot weather. Who’s not in love with spending time in the sun, under a beach umbrella, or floating in the pool? But there’s one spot that doesn’t embrace the heat: your house.

For many people, which is why air conditioning is important. Unfortunately, not everyone is lucky enough to have a central air conditioning system that, no matter how hot it is outside, keeps a comfortable temperature in their house.

Window air conditioners have always been the remedy, but units that protrude from a window are not permitted by certain apartments and city ordinances. Don’t worry, that doesn’t mean that for a long, hot summer you’re trapped in agony! Small p ortable air conditioners are an excellent option because, without being visible from the outside, they can cool the room as easily as a window device.

Benefits of a small portable air conditioner

You don’t have to think about municipal or building laws prohibiting equipment protruding from your house with a portable air conditioner. You certainly would not loose any of your eyes or natural light because the air conditioner does not fill up the whole window. By supplementing a central air conditioning system, a portable air conditioner will also help decrease electricity costs.

You should raise the temperature of the central air conditioner and turn the portable unit on in the place you want to cool if you only need to cool one or two rooms. A portable air conditioner should be transferred from room to room because it is bulky so that the ventilation system can be conveniently tailored to your needs.


Much as for a window air conditioner, when buying a portable air conditioner, the most important choice you need to make is what size to take. The strength of a portable air conditioner you require in a given room may be compromised by inadequate insulation and other factors in your house.


A one year warranty comes for most portable AC units. This guarantee can not be provided by cheaper models, whereas more costly units also give up to five years’ warranty. Before buying it, make sure to check the warranty specifics of a device to ensure your investment is secured. Some warranties protect only certain goods, such as materials, but not labour.

Therefore, it is important to consider specifically what you are receiving with the pledge. The LG 14,000 BTU portable air conditioner is a decent option for those wanting to cool a large portion of a house or apartment with air conditioning. It’s silent, simple to mount, and strong enough to cool 500 square feet of area.

Energy efficiency

A higher electricity bill typically comes from using an air conditioner. This is why choosing a portable model that is as energy efficient as possible is important. As they are deemed to follow energy efficiency requirements, search for models that bear the Energy Star tag.

It is also prudent to search for a handheld computer fitted with an energy saving mode or a programmable thermostat. Thus, when it reaches the temperature you have specified, it will immediately turn off.

Role of dehumidifier

Any of the moisture may be extracted from the air by any portable air conditioner. Some versions, however, are fitted with a dehumidification feature. Without adding cool air, this feature helps you to reduce the humidity in your house. Therefore, on humid days that are not inherently hot enough to need air conditioning, it performs well.

Level of Noise

It is likely that – like all air conditioners while they are on – the portable air conditioner would produce noise. Some models, though, are louder than others and can add more to your house than white noise.

Your safest choice is to use a system that is built to be as silent as possible, if you are worried with noise levels. To see how they do, you should compare the decibel (dB) levels of the models you are considering. 45 dBs indicates an AC system with low noise.


You would think that the portable air conditioner would be… yeah, portable, but the fact is, it’s normally very heavy. They can weigh up to 100 pounds, so it can be hard to carry them from room to room, though they are easier to move than a window device.

If your air conditioning system is to be used in many spaces, select a model that has casters or wheels to ease the operation. Be vigilant when bringing the air conditioner up and down the stairs too.


The evaporative cooler Honeywell C060PM takes much less electricity to work than air conditioners. It can cool indoors up to 825 square feet and even cool outside areas, such as a tent or patio.


You want your handheld air conditioner to be as convenient to use as possible, so you should be using user-friendly controls. Digital displayed models are usually the simplest to use, so aim for a device with a screen not too bright, which could annoy you when the lights are out.

Furthermore, a remote control may be helpful when you use the air conditioning in a big space or if you do not want to leave the bed to change it. Look for a remote control that can turn the computer on and off and adjust the speed at least.


A portable air conditioner will take up some space in the room you put – which will be impossible to miss – so you have to remember its appearance while shopping. The devices are available in various esthetic types but appear to offer preference to feature rather than shape. In most instances, you can select from simple colors such as white, gray or black.

Necessary maintenance

You must consider the maintenance needed to keep the appliance cooling properly while considering a portable air conditioner. The humidity that your air conditioner extracts from the air is contained in it and you have to get rid of it. Some systems need you to empty a bin, attach a tube, or pump water to periodically extract moisture.

Decide if you want the water to be disposed of, taking into account the location of the unit and the access to the water obtained. Look for an auto-evaporator model if this seems like a challenge for you. This ensures that the moisture it extracts will evaporate, so that you don’t have to get rid of it yourself.
