While the weather is cold, no one’s going to be thinking about turning on their ACs. After all, it is already cold! However, as the weather gets warmer, many people start to think about turning on their AC to keep things cool. But what happens if you find that one room that just needs a little extra cooling? Well, it might be a great idea to invest in a portable air conditioner. After all, who doesn’t love the idea of being able to cool down their home or office with the push of a button?

However, before you go out and buy the first portable air conditioner you see, there are a few things you need to take into consideration. In this blog post, we’ll go over some of the most important factors to keep in mind when choosing a portable air conditioner:

1. Size

The first thing to consider is the size of the unit. You need to make sure that it is powerful enough to cool the room you want to use it in but not so powerful that it is too noisy or uses too much energy. A good rule of thumb is to choose a unit that is about 20% larger than the room you want to cool.

2. BTUs

BTUs, or British Thermal Units, are a measure of how much heat a unit can remove from the air in an hour. The higher the BTU rating, the more powerful the air conditioner. Portable air conditioners typically have BTU ratings between 7,000 and 14,000, so pick one that works for how fast you want a room to be cooled.

3. Energy Efficiency

Energy efficiency is an important consideration for any appliance, but it is especially important for air conditioners because they use a lot of energy. Look for a unit that has an Energy Efficiency Ratio (EER) of at least 10. This means that for every 1 unit of energy the unit uses, it will generate ten units of cooling power. This way, you can minimise your electricity usage while still enjoying that perfectly cool room.

4. Portability

One of the main advantages of a portable air conditioner is that it can be moved from room to room as needed. But not all units are created equal when it comes to portability. Some units are very heavy and difficult to move, while others have wheels or built-in handles that make them easy to transport. Consider how often you will need to move the unit, and choose one that will be easy to move when necessary.

5. Warranty

As with any appliance, it is important to choose a unit that comes with a good warranty. This will protect you in case the unit breaks down or stops working properly. Most portable air conditioners come with a 1-year warranty, but some extend to two or even three years.


With the above considerations made, you stand a much better chance of picking the perfect portable air conditioner that’ll meet your cooling needs without breaking the bank. That being said, always sit back and understand your needs before taking action. In doing so, you can figure out exactly what you want your portable AC to do, making choosing one all the easier!
