Choosing the right air conditioner

If you’re reading this, you’re probably in the market for an air conditioner. Like most people who come to us for air conditioning advice, they don’t have much of an idea of what they are looking for besides the obvious – relief from the relentless summer heat.

It’s okay if you know next to nothing about air conditioners. That’s what this blog is for. In it, we are going to look at a number of factors you need to consider when picking an air conditioner for your home. To make things easier, we are only going to look at two different systems: split and ducted.

While the information presented here may not be able to provide any concrete solutions, it’s definitely going to get you thinking about it before you set foot into a retailer. Having a better understanding of what you actually need is going to help you pick the right conditioning system when it comes time to buy.

How many rooms need to be cooled?

If you only need one room cooled (i.e. living room or a bedroom), then picking a split system is probably the best foot forward. Split systems are ideal for small apartments. If, on the other hand, you need multiple rooms cooled, this is where it becomes a little more complex.

If you think you need ducted air conditioning, it’s best to seek professional advice, simply because you really need to get the most suitable system for energy efficiency and longevity of the unit.

Room size

When choosing an air conditioner (and in particular a split system), you want to select one for the right cooling capacity for your room. Having a system where the cooling capacity is too high for the space is grossly inefficient (in terms of energy use and operating costs), despite the fact that it will get cooler much quicker. It is also known to reduce the lifespan of the system.

So how do you determine what the correct cooling output should be? Well, besides a professional doing, you might want to work it out for yourself using this size calculator.


An air conditioner is an expensive appliance. You want something that is going to run efficiently for you many years to come. Even though the cheaper price tag of lesser known brands can be appealing, it’s best to go with a well-established brand.

At Cool Technology, we have a wide range of brands available, however, in most cases, we recommend Panasonic models because they are reliable machines at a reasonable price.

Energy Efficiency

In Australia, air conditioners are sold with an energy star rating label. This is compulsory to have on all new systems. The more stars shown on the label, the great the efficiency.

Units that are highly efficient will be more expensive initially, but the savings you make over the lifespan of the system from reduced running costs will make it cost effective.

If you can afford it, we recommend you buy an air conditioner with a high energy efficiency.

These are just a few things you need to consider when buying an air conditioner for your home. If you’re ready to take the next step or require more advice, then feel free to contact us.
