How To Choose The Right Air Conditioner (Part 2)

One of the most important steps when choosing an air conditioner is making sure you choose the right size air conditioner for your needs. This is important because if your air conditioner is too large or too small for your needs it will not run as it was designed to which can have negative effects including:

  • If Your Air Conditioner Is Too Large

If you choose an air conditioner that is too large for your needs it will cool the room quickly and then turn off. This means that the air conditioner won’t stay on long enough to complete its cycle and control the humidity in the room. As a result, you will be left with a cold and clammy feeling room.

  • If Your Air Conditioner Is Too Small

Conversely, if you choose an air conditioner that is too small for your needs, the air conditioner will be working on overdrive to cool the area. This will cause your air conditioner to age prematurely, reducing the lifetime of the system. Additionally, your air conditioner will be constantly running as it doesn’t have the power to cool the area to the set temperature, which will cause your electricity bill to skyrocket.

So, how do you choose an air conditioner that is perfectly sized for your needs?

How To Choose The Right Size Air Conditioner

To calculate what size air conditioner you need you will need to know the area (in metres squared) of the room that you are cooling. To find the area of the room, simply multiply the length of the room by the width of the room. Once you have found the area of the room, you will need to multiply it by 0.15kW to find out how big your air conditioner should be.

For example, if you’re looking to cool a room that is 5 metres wide and 7 metres long, multiply 5 by 7 to find the area.

 

EXAMPLE:

calculate the right size air conditioner

Area of the room = 5m x 7m = 35m²

Next, multiply the area of the room (35m²) by 0.15kW.

35 x 0.15kW = 5.25kW

So to cool a room that is 5 metres wide and 7 metres long you will need a 5.2kW air conditioner*.

*Note: sizes are calculated assuming a standard ceiling height of 2.4m and standard window sizes.

Other Factors To Consider

It is also important to note that when choosing which size air conditioner is best suited to your needs you should take into account windows and insulation of the room to be cooled. If the room you need to cool has larger than average windows or poor insulation, you may need a larger air conditioner. Conversely, if the room has small windows or is well insulated you may need a smaller air conditioner.
