How to Choose a Split System Air Conditioner in Australia

When looking for the best brand of split system air conditioners in Australia, most people buy whatever comes first and end up making the costly mistake of over- or undersizing. 

The end results?

Wastage energy, insufficient cooling, higher power bills and accelerated wear and tear.

Don’t be among the misinformed buyers; consider these factors before making a purchase.

Size and Cooling Capacity Are Important

First off, determine how large the area or room that you’ll be heating or cooling is. 

The air conditioner has to be compatible with the space—otherwise, you’ll be hot and sweaty with a system unable to cool down or waste money (and energy) on a system that’s too large.

“A rule of thumb is to estimate around 150 watts per square meter. So if you have a 20m² area, you’re around a 3.0kw unit.”

Search for Energy Efficiency

As electricity prices increase, it’s wise to buy highly efficient split systems that will save on power use. To check how efficient the unit is, compare its Energy Star rating. 

Those with more stars are built to deliver optimal heating/cooling without minimal energy input. 

Also, prioritise models with inverter technology. Such systems adjust their output to match the requirements of a particular room, so they don’t start and stop repeatedly like traditional systems. 

This reduces the wear and tear on your system, conserves power, and maintains a more stable temperature.

Mind the Noise Level

No one enjoys having a noisy unit thrumming in the background, particularly in a bedroom or study area. 

Unfortunately, most split systems can have noticeable noise levels, although these differ between models and makes. 

When buying, you should check the decibel (db) ratings, which tell you more about the unit’s noise level. According to experts, picking those below 40 db ensures peaceful operations.

Consider Both Heating and Cooling

In most places in Australia, winters can be freezing cold while summer can be scorching hot, so it’s a good idea to opt for a reverse cycle split system that does both heating and cooling. 

In winter, the device will keep you warm, and in summer, you will stay cool without spending extra costs on an extra heating device. 

Consider Indoor Air Quality

Most of us don’t even know that our air conditioners have a role to play in improving the quality of air indoors, but they actually do.

Some air conditioners have built-in filters to capture dust, pet dander, pollen and even smoky particles from the air, keeping it clean. 

This is a must-have option, especially if you are allergic to dust particles.

Consider Installation and Recurring Maintenance

Not all split systems are easy to install or maintain; some are more complicated and will require more labour costs. 

That’s why it makes sense to consider the installation complexity and maintenance requirements of your split systems.

Choosing a system that’s straightforward to install and low on maintenance won’t just save you money upfront; it’ll also mean fewer headaches down the line.
