The 3 Most Common Air Conditioner Problems in Brisbane Homes

At SJK Collective, we know how important a reliable air conditioner is for Brisbane households, especially in our hot and humid summers. Whether you’re in Kedron, Eagle Farm, or Everton Park, our licensed HVAC technicians often see the same recurring issues across local homes and businesses.

Here are the top three most common air conditioning problems we fix for Brisbane Northside residents, and what you can do to prevent them.

1. Dirty or Clogged Filters Causing Blocked Airflow

Why it matters
When filters collect dust, dirt and debris, your system struggles to move air. This reduces cooling efficiency, increases energy bills, and can even cause your evaporator coils to freeze. Poor airflow also leads to reduced indoor air quality, which is the last thing you want in Brisbane’s humid climate.

Local insight
Many Kedron and Everton Park homeowners are surprised at how quickly filters clog, especially during summer. Even newer split system aircon units need regular cleaning to keep them working properly.

What you can do
Clean or replace your filters every 2–3 months, or more often if you use your AC daily. For a deeper clean, book a professional air conditioning service in Eagle Farm, Kedron or Everton Park to ensure your unit is performing at its best.

2. Frozen Evaporator Coils or Ice Build-Up

Why it matters
Frozen coils are often caused by restricted airflow from dirty filters or blocked vents. When coils ice over, your system can’t cool the air properly and may eventually shut down or become damaged.

Local insight
We frequently attend callouts in Kedron and Everton Park for aircon repairs where ice build-up was left untreated. In Brisbane’s heat, this can quickly escalate into an urgent situation requiring emergency aircon repair.

What you can do
If you notice ice on your indoor or outdoor unit, switch the system off and let it defrost. Check your filters and vents. If the issue continues, it’s time to call a licensed aircon technician in Kedron, Eagle Farm or Everton Park for a proper inspection.

3. Refrigerant Leaks and Low Refrigerant Levels

Why it matters
Refrigerant is what makes your system cool the air. If your unit has a leak or is running low, you’ll notice poor cooling performance, higher energy use and extra strain on your system.

Local insight
Our HVAC specialists in Eagle Farm often diagnose refrigerant leaks during servicing jobs. These repairs require professional attention, as the system needs to be sealed and regassed to operate safely.

What you can do
If you hear hissing noises, notice weak cooling, or find that your unit runs constantly without lowering the temperature, book an air conditioning repair service in Kedron, Everton Park or Eagle Farm as soon as possible.

What Brisbane Homeowners Are Saying

Even locals agree maintenance makes all the difference:

“It seems it’s time to remind everyone that air conditioners require maintenance … cleaning the dust filters is very simple … companies can do a split system for $90–$180 depending on the level of filth.” — Brisbane Reddit user

“With the water spilling, it sounds like the drain is blocked. Get a tech out asap and get them to do a full clean with mould removal …” — Brisbane Reddit user

Regular maintenance not only saves money on repairs but also keeps your home cool and comfortable all summer long.
