How to Choose the Right Size Air Conditioner for Your Home

You want air conditioning for your Australian home but you don’t know which size air conditioner to choose? It can be confusing, as multiple factors go into selecting the right size air conditioner for your home. The key is to make sure that the unit you select is powerful enough to cool your space – not too big and not too small. You need the Goldilocks of air conditioning systems if you will. Today, we’ll explore some considerations to keep in mind!

First, you’ll need to calculate the size of your room or space. This will help you determine how much cooling power is required and what size air conditioner is right for you. Measure the length, width, and height of the area that needs to be cooled. Take these measurements in metres and multiply them together – this will give you an approximate square metre measurement of the space.

Once you have that number, check the manufacturer’s specifications to find out how much cooling power your AC unit needs in relation to the size of the room. The most common rule of thumb is that an air conditioner should provide around 20 BTUs (British Thermal Units) per square metre. This can vary depending on the type of room and climate, but it’s a good starting point.

You also need to consider other factors before selecting an AC unit. The size of any windows in the room should be taken into account as they let in heat from outside. If there are multiple stories or rooms that need air conditioning, calculate the total area of all rooms and calculate the BTUs for each one individually.

When you’ve calculated the BTUs needed for your room(s), it’s time to select a unit. Look at different size air conditioners and compare their cooling capacities (or ‘tonnage’) to see which one is right for your space. The higher the tonnage, the more powerful the air conditioner.

When shopping for a unit, look at its features and energy efficiency ratings to make sure you’re getting the best value for money. An Energy Star-rated product can help reduce your electricity bills. Additionally, if you’re looking for a more cost-effective way to cool your home, you should consider buying a ductless mini-split system.
