What Is the Best Size of Air Conditioner to Get for My Home?

Australian heat can be intense in the summertime, and you will need a high-quality air conditioner to make your living conditions more tolerable. There are different sizes of air conditioners, and depending on the size of your home, you will need to get a specific system and size.

Why Is It Important to Get the Correct Size Air Conditioner?

You need to get the correct size air conditioning system because you want to make sure that it can cool your home efficiently. The capacity of the system you will need is determined by the size of the space you are trying to heat or cool. An A/C that is too small may never be able to cool the room as needed; one that is too large may draw too much power or keep your room way too cold. 

What Size Air Conditioner Do I Have to Get?

Where you live determines what size air conditioner you will need to get. If you have a small apartment or a couple of rooms in your house, you should be able to get away with a smaller air conditioner. If you live in a bigger house, you may need a more oversized air conditioner to keep your entire home cool.

However, it is not only the size of the rooms or property that will affect your air conditioner size. There are also other factors that you will need to consider.

What Are the Other Factors That I Will Need to Consider?

You will need to find out the heating and cooling capacity of your home and the average temperature of the room you want to cool. You also need to consider the room’s insulation where you want to place the air conditioner.

Some other factors that will affect the size of the air conditioner are lighting, the number of people who live in your home, and your home’s foundation. While these may seem irrelevant, they can significantly affect air conditioners’ heating and cooling efficiency.

How Do I Know What Size Air Conditioner I Will Need?

While there are ways to do this on your own, such as using a formula or online calculator. We recommend you talk to a professional to get this done. Working with a professional will guarantee that accurate measurements are made, so that you will not have to worry about purchasing the wrong size unit. 

When you request a quote from an AC expert, there is a formula that is used to measure your home or the space you want to service, and this ensures that the correct unit is installed based on its heating and cooling capacity. 


When it comes to air conditioners, you will want to ensure that you get the best quality, especially as you are entrusting it to keep you cool during summer and warm in the winter.  It is good to make sure that you get a reputable brand air conditioner and one that is the right capacity for the space you are trying to cool/heat.
