When it comes to air conditioning, one of the biggest concerns every household has remains the electricity costs. Brisbane’s hot and humid summers make energy efficient methods a number one priority. This is where inverter air conditioning steps into the picture.

 Inverter or non-inverter?

First and foremost, before unveiling the benefits of this technology, let’s learn about the differences between an inverter and a non-inverter air conditioner.

  • Non-inverter

Also known as conventional air conditioners, the compressor in the outdoor unit is either working at full power or completely shut down. To achieve a good performance and comfort, it means that the compressor needs to switch on and off every time is needed.

This fact can lead to more wear and tear on the compressor, using much more power to start up each time. This kind of models can be cheaper to buy but they don’t have the long-term benefits that the inverter models offer. 

  • Inverter

In this case, an inverter is used to control and vary the speed of the compressor motor, similar to a car. In other words, the compressor from the outdoor unit doesn’t have to switch on and off continuously but it speeds up or down when necessary.

By not having to stop and start several times a day, there is less stress on the compressor and the other parts of the system. Nowadays, most split systems on the market are inverter models.


Advantages of inverter air conditioning

  • Low Running Costs

As summer kicks in, the electricity bill starts to be a very hot topic in each home. Hence, an unconditional use of air conditioning could lead to astronomical power bills.

If you are planning to buy your first air conditioner or replace the old one, then it only makes sense to choose a model that comes with the inverter technology. Whilst the initial investment may be slightly bigger, your long-term savings, on the other hand, will overcome any drawback.

  • Comfort

This is probably as important as the benefit that we’ve previously mentioned. With the peace of mind that comes from having a highly efficient air conditioner, your family could use it anytime is needed. You could instantly turn on the cooling or preset your climate control to turn it on during hot summer afternoons. Enjoy your home comfort!

  • Environmental friendly

Inverter air conditioning systems are unquestionably friendlier to the environment than the non-inverter ones.

For instance, if a room has been sufficiently cooled to its desired temperature level, the inverter scales down the power to only maintain that climate.

This low power mode leads to reduced electricity usage and environmental impact, which is why inverter models feature higher energy star ratings than non-inverter ones.


Inverter brands & technologies

Inverter technology was first introduced by Toshiba back in 1981 and since then it has always maintained a technological advantage.

Over the course of time, however, other big manufacturers started their own implementation of inverter technology, each with its own benefits. Most of the latest inverter AC models have a very strong focus on efficient operation, combined with low power mode, low standby power or other power-efficient functions.

To name a few, here are some of the most popular inverter technologies by brand:

  • Toshiba – DC Hybrid inverter
  • Mitsubishi Electric – Vector-wave Eco Inverter
  • Panasonic – Intelligent inverter
  • Daikin – Premium Inverter Ducted Technology
  • Samsung – Smart Inverter




Inverter technology provides a more precise room temperature by continuously controlling the temperature, without experiencing the temperature fluctuations of fixed speed air conditioning systems.

Bear in mind that inverter air conditioning systems are approximately 30% more efficient than fixed speed units and can reach the desired room temperature quicker. Besides an increased efficiency compared to conventional air conditioners, they are quieter and feature lower operating cost. Due to their consistency, inverter systems can be more durable and reliable.

Whilst the inverter systems may be more expensive than the constant speed air conditioners, this is balanced by lower energy bills overall. The payback time is approximately two years depending on the usage.

Until next time, stay cool and have yourself a merry Christmas!
