As Brisbane edges into the humid months, locals from Belmont, Capalaba, Chandler, Mackenzie, Gumdale, Wakerley, Cannon Hill, and Sheldon know exactly what’s coming, long, sticky days, restless nights, and the unmistakable buzz of air conditioners working overtime.
From October onwards, Brisbane transitions from mild spring days into the start of a long, humid summer that runs through to March. While the heat ramps up, so do common air conditioning and HVAC issues that can impact comfort, air quality, and even your energy bills.
The Most Common Air Conditioning Issues in Brisbane’s Humid Season
Mould in Aircon Units
With humidity on the rise, mould in aircon units becomes a major concern across Brisbane homes. When warm, moist air passes through your system, it creates the perfect breeding ground for mould and mildew, especially if your filters or coils haven’t been cleaned in a while.
Left untreated, this can cause musty smells, trigger allergies, and even spread mould spores throughout your home.
How to Get Rid of Mould in Aircon:
- Turn off and unplug your unit.
- Remove the cover and filters.
- Use a specific air conditioner cleaner or natural solution like tea tree oil and water to wipe away mould.
- Let everything dry completely before reassembling.
If mould keeps returning, it’s time for a professional HVAC cleaning or servicing, a small investment that can prevent bigger health and maintenance issues later.
Aircon and Humidity Control
During Brisbane’s sticky months (November–March), your air conditioner works harder to pull moisture from the air. But when humidity is extreme, even the best systems can struggle.
If your aircon is running constantly but not cooling properly, or your rooms feel damp rather than cool, you might be facing HVAC humidity issues.
- Try using your aircon’s humidity mode if available.
- Set your temperature to around 24°C for comfort and efficiency.
- Pair your system with a dehumidifier for stubborn humidity problems.
Reduced Cooling Efficiency and Rising Energy Bills
As air conditioners battle higher moisture levels, they often need to work harder and longer, which means increased energy use. This can lead to HVAC issues not cooling properly, even when the unit seems to be running fine.
Make sure your unit is the right size for your home, and have it serviced regularly to prevent clogged filters, low refrigerant, or worn components from draining its performance.
Hidden HVAC Problems: Pests and Mould Build-up
Warm, overworked outdoor units can attract pests like geckos, which can sneak inside and damage circuit boards. Combine that with internal mould build-up or blocked filters, and you’ve got a recipe for breakdowns.
Keeping your system clean and having an expert inspect your air conditioning unit before the peak of summer can save you a costly emergency callout later.
Simple Fixes for Common HVAC Issues
- Clean filters and coils at least once a month during summer.
- Improve ventilation, use extractor fans or cross-ventilation to reduce moisture indoors.
- Check insulation in walls and ceilings to reduce cooling load.
- Install zoning systems so each room can be cooled independently, perfect for large homes in Belmont or Capalaba.
Why Regular Maintenance Matters
Skipping maintenance might not seem like a big deal until your system fails on a 36°C day. Regular servicing keeps your air conditioning efficient, helps prevent mould growth, and can extend your system’s lifespan.
