Mini Portable Air Conditioner – Buyer’s Guide

When planning to purchase the best mini portable air conditioner, you need various factors to consider that are discussed below.

Unit Size

The unit size of the portable air conditioner is the first thing that you should look into. These small AC units usually come with the 25 to 35 inches height and 12 to 18 inches width. So, when going to buy the AC, make sure that its height, width, and weight are according to your needs.

But in order to buy the compactly sized air conditioner, don’t comprise on the performance. If you have low space available, go with those units that cover the minimal space. But, if you want the AC for large rooms, height and weight are important to consider. Moreover, portability is also necessary to consider, but after finding the perfect spot near the electrical outlet or window, there will be no need to move the unit.

Cooling Power

Cooling of Air Conditioner

The cooling power of the air conditioner is another most important factor to note down. BTU is the unit of measuring the cooling power of the portable ACs. So, the higher the BTU rating, the higher will be the speed to remove the heat from the air that will make the room cool faster.

But many manufacturers don’t mention the exact BTU power and it always comes lower than expected. But, many air conditioners possess the ability to make the rooms cool even at reduced BTU levels which is a great thing.

Generally, 20 BTU requires making one square feet area cooler, so you can easily calculate how much BTU power you will need to make your room cool according to its size.

But it is also necessary to count other factors such as climate, the height of the room, window size, humidity, and the direct sunlight that reaches to your room.

So, before going to purchase the mini portable air conditioner, measure the size of the room to have an estimated cooling power in your mind. Also, consider the other factors including the environmental ones.

Noise level

Noise level is also another factor that is not essential, but you can take into consideration. Some portable air conditioners produce very less sound during operation, and there are some that are quite louder. So, it is best to go with a quieter unit if you always need total silence in the room while sleeping.

The noise level that the portable AC produce falls between the range of 50dB to 80dB. So, it is better to focus on the noise level before purchasing to get the unit that makes less noise.


Control of Portable AC

Some portable air conditioners are controlled with remote controls and louvers, whereas some are controlled manually. It all depends on your needs what type of controls you want in your unit.

Some models restart automatically after the power interruption on the same settings. Also, some units offer 24-hour on/off timer that automatically turns them on and off when required.

  • Units with improved air circulation and ventilation are also ideal to go with. The models that come with the auto-swing option are best to purchase.
