Is a Portable Air Conditioner Right for You?

As with any purchase, it’s important to first determine if it’s going to be the right choice. A portable air conditioner is no different, and you need to be sure that it’s going to work with your home. Let’s go through a few of the key factors to consider. 

It’s first important to note that while portable air conditioners are great at keeping you cool, they are not as effective as the full-size standard models. 

However, a standard air conditioner also requires lengthy and expensive installation where a portable model does not. 

Similarly, portable air conditioning models don’t tend to need a lot of maintenance – making them cheaper in the long run. 

Additionally, a portable model can be unplugged and stored away when summer is over. This is a brilliant option to have and something that the full-size models lack. 

Many of them also double up as dehumidifiers, air purifiers, and heaters, bringing an extra element to their overall usefulness. 

 They cost a lot less to purchase than standard models, which can be a blessing. With regards to energy efficiency, they are cheaper to run but only because of their smaller size. Those with a higher energy efficiency rating will be cheaper to run as well, a factor worth considering.

How to Choose a Portable Air Conditioner

Before you buy a portable air conditioner, there are a few features that you should take into consideration. These will help you decide on the type of air conditioner that you want as well as any additional perks that might be appealing to you. 

Noise Level. Generally speaking, you’re going to want a model that runs relatively quietly. Most of the ones we have chosen are below 65dB, which is superb for bedrooms, living rooms, and home offices. 

Additionally, if you use a window kit you can expect the volume to go down even lower. Some of our chosen models feature silent running, which means they operate at under 50dB for a quiet and peaceful night. 

Hose Length. The length of the exhaust hose is an important factor because it helps you to determine where you will place your portable air conditioner. A short hose means it will need to be close to the window, whereas a long one will give you more freedom for placement. 

Room Size. You have to ensure that the air conditioning units you choose are suitable for the room you want to use them in. If you purchase a model that’s able to cool a small room and place it in a large one, you’re going to be left very toasty this summer. 

Size and Weight. Consider the size of the model before you buy. Is it going to take up too much room? Would you prefer a short or tall one? Additionally, pay attention to the weight and how portable it is. 

If it is quite heavy but has wheels, it will be a lot easier to move. But if it is heavy and has a handle, it may prove to be a lot harder. 

Features. Think about the additional features you want your model to have. Most portable air conditioners come with dehumidification, fan speeds, and sleep mode or a timer. However, there are also some that come with heating capabilities. 

Features aren’t always make or break, but they can add a lot of versatility to your chosen air conditioning model. 

Warranty. Most companies offer a year-long warranty for their portable air conditioners. This will tend to include parts and labour if there is a malfunction or it breaks down. Some companies may also provide an extended warranty when you register online, so make sure you check.


Do all Portable Air Conditioners Have to be Vented Out a Window?

Yes, all portable air conditioners do have to be vented out a window. You will not find a model without a hose, and this is because the exhaust hose is an integral part of the air conditioner. 

It removes hot air and moisture from the room and expels it outside, ensuring that your indoor air remains clean and does not become muggy, or a prime place for mould and mildew to grow.

What Happens if You Don’t Vent a Portable Air Conditioner?

If you don’t vent a portable air conditioner, the hot air becomes trapped in the room. The reason that this isn’t a great thing to happen is that it negates the effects of the air cooler. This means that your air conditioner becomes ineffective and won’t keep your home cool.

How Long Should a Portable Air Conditioner Last?

Generally speaking, your portable air conditioner should last for about ten years. They are quite sturdy and reliable machines, offering plenty of cool air while also being easy to move around.

Do Portable Air Conditioners Have to be Emptied?

Yes and no, portable air conditioners have to be emptied depending on what type they are. Those that also act as dehumidifiers will need to be emptied when the tank is full. Portable air conditioners that are solely for cooling air do not need to be drained unless they malfunction.

Do You Have to Put Water in a Portable Air Conditioner?

Yes, there are some models that will require you to fill them with water. However, many models of portable air conditioner don’t need this. Evaporative tanks need to be filled with water and regular ones need to be emptied, it just depends on the type you buy.

Can You Run a Portable AC all Day?

Yes, you can run a portable AC all day. Generally speaking, there is no risk to leaving it running. However, you may find that your electricity bill climbs up if it is left to run 24/7.
