Different Types of Air Conditioners for Small Rooms

There are several different types of air conditioners in the market ideal for small rooms. They include:

Window Air Conditioner

The 5000 BT window air conditioner is cheap and tiny to offer you convenience when you want to use it. This type of AC has a compact design, efficient, easy to use and install in your window. 

Portable Air Conditioner

This AC unit is smaller than the 5000 BTU AC but expensive. However, the benefit of using this AC unit is that it’s easy to carry and move from one room to the other. 

Battery-Powered Air Conditioner

The battery-powered AC unit uses 2300 BTU and the good thing about it is that it’s cheaper and efficient. Although it requires batteries, its benefit is that you can use it anywhere like in your room, RV, or office desk.

Air Conditioners vs Evaporative Coolers

Air conditioners and evaporative coolers differ in various ways such as functioning and features. Air conditioners eliminate heat and moisture inside a space through the use of refrigerants. Air conditioners use fans to distribute the conditioned air to improve thermal comfort and indoor air quality.

Evaporative coolers, on the other hand, only need few materials to operate. These may include water and electricity. What’s more, evaporative coolers don’t require much maintenance compared to air conditioners. They can help you save a lot of money in a year than using air conditioners. However, evaporative coolers don’t produce any mist, spray water, or fog. 

Which is the Best Option?

Both air conditioners and evaporative coolers are beneficial in their own ways. Each has its advantages and disadvantages. Therefore, it’s up to you to decide the most ideal option for your needs. 

As you’ve seen, air conditioners are effective, portable, efficient, and require regular maintenance. Air coolers are also efficient, require less maintenance, and can help you save money in the long term. Both air conditioners and evaporative coolers are suitable to use, but it will depend on your preferences.

Sizing Air Conditioner for Your Room

Sizing an air conditioner is one of the most important factors to consider before even buying one. Selecting a smaller unit than your room will not be effective enough to provide the cool temperature you need. Also, buying an oversized AC may cool the room faster but cycle on and off inefficiently, thereby resulting in high electricity costs.

To calculate the ideal size of an air conditioner, you need to multiply the length and width of your room. Once you find the result, multiply it by 25 BTU and this will give you the proper cooling suitable for all-weather seasons.

Other Factors to Consider when Choosing Air Conditioners

Some of the factors you need to consider when choosing an air conditioner include:


The cost of an air conditioner contributes to its effectiveness. Cheap is expensive. Therefore, you should always strive to buy an AC sold at a considerable price and one that offers value for money.


Although most people consider the cost of an AC more, it’s also important to check the quality. There are costly AC units that are high-quality, while others don’t offer much value. Focus more on the specifications of the AC you want to buy to ensure you don’t end up regretting it later on.


The size of your room will dictate the size of the AC unit you’ll buy. When you want to buy an air conditioner, ensure it has the right size to be effective where you want to use it. Large rooms require large ACs while small rooms require smaller ACs. You can also buy a portable or mini air conditioner for personal use or while traveling.


Whenever I want to buy an air conditioner, I always conduct thorough research to find out whether it’s durable or not. You should buy a durable AC unit that needs less maintenance or replacement.
