How to Get the Right Size Air Conditioner

How to Get the Right Size Air Conditioner

Summer brings joy to many people in Australia as it means they can get out in the sun, sea and surf.

But for those who are stuck at home, the heat can get oppressive if they don’t have an adequate air con.

Getting the right size cooling system is essential so the best air conditioning services Newcastle has to offer – Breeze Air – will help you keep your cool.

Air Conditioning Size matters

The main consideration when buying a new air conditioning system is the size of the space it needs to cool.

If an air con is too big, it will rapidly cool down your space and stop the cycle before it can fully finish.

As the temperature increases, the cycle will begin again but will cut short even sooner each time.

This is hugely inefficient as the constant loop of turning on and off will drain power and your bank account too.

A system that is too small may not even be able to bring the temperature down to desirable levels.

Even if it can adequately cool the room, it will have to run constantly to keep up and it goes without saying, this isn’t ideal for your wallet.

Cool calculations

The unit of measurement for energy output is the kilowatt (kW), which is 1000 watts, and it is the easiest metric to use when working out the size of system you need for your space.

There are a few different ways to figure out the right kW output.

One way is to get the expert team at Breeze Air, providers of air conditioning systems Newcastle residents have come to trust, to precisely inspect the area and do all the maths for you.

There are online calculators that can be reasonably accurate, or you can use a simple formula to get a rough idea of what size air conditioning system is right for you.

You will need to find out the area of the rooms you want cooled by measuring the length and width of the room and multiplying them together.

Once you have done that for each room, add all the areas together which will give you the sum in square metres (m²).

Then you will have to measure your ceiling height which should either be 2.4m, 2.7m or 3m and multiply that by the sum of the floorspace.

For a 2.4m high ceiling, multiply the floorspace area by 150 (watts); a 2.7m ceiling will mean you multiple the floorspace area by 160 watts; and a 3m height means you multiply the area by 175 watts.

For example, if your floorspace is 100m² then:

100m² x 150 watts = 15 000 watts. Divide by 1000 and you will have 15 kW, which should be just the right size for your home.
