Aircon maintenance in Australia isn’t something we get to leave till next year anymore because of the crazy energy demands and blistering heat waves that are popping up all over the place. You might not even notice it at first, but when summer starts pushing the mercury above 35°C it starts to take its toll on your aircon system. When these things aren’t properly looked after they can start to lose up to 20% of their efficiency because of restricted airflow and worn out parts. And just when you thought things couldn’t get any worse, your electricity bill starts to climb by as much as 25% during heatwaves that top 40°C. So now residential cooling is getting managed in a whole new way, with data from energy authorities and HVAC experts making a pretty strong case for getting your aircon serviced before the start of each season. This helps keep it running smoothly, reduce the chances of it breaking down and give it a good long life.
Pre-Season Inspection and Load Assessment
Pre-season inspection and load assessment has become the benchmark for whether your residential cooling system is going to make it through the summer or not, especially with the northern and western regions of Australia regularly seeing temperatures exceeding 35°C. And it’s not just a total system failure you need to worry about either. The efficiency of the system can actually degrade by up to 20% if it’s not looked after properly, just because dust and wear and tear are clogging up the works and making it work harder. When we do field audits in homes that are really struggling, we find that their electricity bill can shoot up by as much as 25% when it gets really hot. That’s a lot of extra pressure on the grid and it’s making it harder for systems to do their job. Meanwhile, long term studies are showing that regular maintenance really does make a big difference to how well your cooling system copes with the heat.
Filter and Airflow Efficiency Management
The state of your filters and airflow has a big impact on how much energy you use in your home. Studies have shown that if your filters get clogged up, your energy usage can go up by 5% to 15% depending where you live and how your split system installation Melbourne made. But doing a bit of maintenance every 90 days can make a big difference. It reduces stress on the compressor and stops dust building up in the filters. It’s especially important in coastal cities like Brisbane and Sydney, where humidity makes filters clog up a lot faster than they do inland. The Australian Building Energy Ratings framework actually takes note of all this and suggests that regular filter maintenance is a key part of keeping your Seasonal Energy Efficiency Ratio stable.
Coil Cleaning and Thermal Performance
One of the biggest reasons that aircon systems start to lose their efficiency is because of all the dust and debris that builds up on the coils. It can reduce heat exchange efficiency by up to 30% if it gets too bad. But if you do your coils regularly, you can save between 10% and 25% on your energy bills, depending on where you live and how hard you are using your system. And if you don’t do the coils at all, and the airflow is all wrong, you can end up paying an extra 12% on your bills every year in really dusty areas.
Refrigerant Management and Leak Detection
Refrigerant undercharge and leaks are still causing all sorts of problems with system efficiency. The data from Australian HVAC servicing shows that even if you’re 10% undercharged, you’re looking at a 20% reduction in cooling capacity and a big hit to your compressor workload. If you’re not checking for leaks for 2 or more years you’re basically asking for trouble. Repair costs can range from AUD 200 to 500, depending on the type of refrigerant and how big your system is. The research also shows that refrigerant leaks in residential systems can go undetected for a year or more. This can rack up losses that add up to 15% or more of your system’s efficiency before you even get around to fixing the problem. And as an added bonus, breaking the rules on leak checks in Australia can land you with higher costs and a worse environmental score.
