Every year, as Adelaide starts to warm up, the same pattern repeats itself. The first real burst of heat arrives, and that’s when people realise their ducted system isn’t quite ready for the season ahead. Some units blow warm air, others make odd noises and a few simply refuse to start. Most of it comes down to one thing – the system hasn’t been checked since last summer.

A little preparation now can save a lot of discomfort later. At aba AIR CONDITIONING, we see it every year – systems that would have performed perfectly with a bit of early attention. This is what you should look at before summer hits.

Start with the Filters

It sounds basic, but filters really do make all the difference. Over time, they collect dust, pollen, and fine debris that block airflow. When the system has to push harder to move air through those filters, it burns more energy and delivers less cooling.

Take them out and have a look. If they are covered in grey dust, they need cleaning or replacing. Washable filters can be rinsed and left to dry fully before going back in. Disposable ones are best replaced altogether. It’s one of the simplest ways to improve cooling instantly.

Check the Ducts — Especially the Hidden Ones

Ductwork often gets ignored because it’s out of sight. But even small leaks or splits in the ducts can lead to huge losses in performance. If some rooms stay warmer than others, or if your system seems to run longer than usual, it could be a sign of leakage.

Sometimes you can spot visible issues in accessible areas, but most of the time, a proper inspection is needed. Our technicians use pressure testing and thermal checks to find leaks quickly. Fixing them early can prevent unnecessary strain on the entire system once those long, hot days arrive.

Give the Outdoor Unit Some Breathing Room

The outdoor unit needs space to work. It expels heat, and if that air can’t move freely because of overgrown plants, leaves, or dust buildup, efficiency drops.

Take a few minutes to clear the area around it, half a metre of open space on each side is ideal. Brush away any dirt, and make sure nothing is blocking the fins or vents. You would be surprised how much smoother the system runs once it can breathe properly again.

Test Before You Need It

Don’t wait for the first hot day to see if your system’s still working. Turn it on early. Let it run for ten or fifteen minutes.

Listen. Does it sound normal? Does the air feel cool and consistent? If the thermostat takes too long to respond or the air doesn’t feel right, that’s a sign the system needs attention. Small irregularities now can become full failures once summer peaks.

Get a Professional Tune-Up

Even if everything seems fine, a pre-season service is worth it. A technician can check refrigerant levels, inspect internal components, and clean parts that aren’t visible without dismantling panels. It’s preventative work that keeps your system running efficiently for years instead of wearing out early.

At aba AIR CONDITIONING professional tune-up every spring. It ensures your ducted system is ready for heavy use and saves you from the scramble of emergency callouts when the first heatwave hits.

Think of It as Insurance for Summer

Most people don’t think about their air conditioner until it fails — usually on a 40-degree day. By spending a little time now, you avoid that risk entirely. Clean filters, sealed ducts, and a tested system mean less power use, more comfort, and peace of mind.

Get your ducted system checked before summer begins. aba AIR CONDITIONING can handle everything, from air conditioner inspection Adelaide, cleaning to servicing and performance testing, so you can face the heat knowing your home will stay cool and reliable all season long.
