7 Common Air Conditioner Issues in Melbourne – And How to Fix Them

Living in Melbourne, we all know how unpredictable the weather can be. One moment it’s cold and windy, the next it’s a scorching 38°C. That’s why having a reliable air conditioning system isn’t just a luxury—it’s a necessity. But even the best systems can run into trouble over time. If your AC isn’t running as it should, don’t sweat it. Here are seven of the most common air conditioner issues in Melbourne homes, and what you can do to get things running smoothly again.
1. The Air Conditioner Won’t Turn On
You get home from work, grab the remote, and... nothing. If your air conditioner refuses to start, begin with the basics. Check if the remote has fresh batteries, confirm the unit is plugged in, and make sure the circuit breaker hasn’t tripped. If all seems fine and it's still not working, the issue could be internal—potentially a faulty thermostat, control board, or blown fuse. This is where calling the professionals at Melbourne Gas & Air makes all the difference.
2. Blowing Warm Air Instead of Cold
An AC that only produces warm air is frustrating, especially during the height of summer. The most common causes are dirty filters, refrigerant leaks, or a malfunctioning compressor. Try cleaning or replacing the filters first. If that doesn’t help, it’s best to book a professional assessment to prevent further damage.
3. Poor or Weak Airflow
If your system seems to be running, but the airflow is weak or uneven, you could be dealing with a clogged filter, obstructed ductwork, or an issue with the fan motor. Regular servicing and maintenance—like what’s offered by Melbourne Gas & Air, your local Air Conditioning Installation Experts—can prevent these issues from building up.
4. Strange Noises From the Unit
Rattling, buzzing, clicking, or grinding noises from your air conditioner are all signs that something isn’t quite right. Loose parts, fan blade obstructions, or electrical problems are all possibilities. Ignoring strange noises can lead to much bigger issues, so it’s important to get your system checked sooner rather than later.
5. Water Leaks or Moisture Buildup
A small amount of condensation is normal, but if you notice excessive water around your indoor unit, it could mean a blocked drain line or a cracked condensate pan. Leaks can lead to mould and structural damage, so don’t delay. A qualified technician from Melbourne Gas & Air can diagnose and fix the issue quickly.
6. Unpleasant Smells Coming From Vents
A musty or foul odour when your AC runs usually indicates mould, mildew, or a burnt electrical component. Replacing air filters and cleaning ducts can help, but persistent smells might require a full system clean. Regular maintenance can prevent this from becoming a recurring issue.
7. High Energy Bills
Has your energy bill suddenly jumped even though your usage hasn’t? An inefficient or overworked system might be to blame. Dusty coils, low refrigerant, or poor airflow can all force your system to use more energy than necessary. Routine service checks and an assessment of your system’s performance can help lower running costs—and keep your home cool more efficiently.
